What are factory sound processors?

Upgrade your sound and keep your factory stereo

Kicker Front Row

Kicker's Front Row puts your music where it should be — right up in front of you

Factory car stereos are getting more and more complicated, as car manufacturers move away from standard-sized receivers to complicated, integrated designs. Often they are tied into a navigation system, climate controls, or other electronic functions, which make swapping them out for aftermarket stereos difficult or even impossible. The problem is, its sound might not be up to your lofty standards.

Replacing the factory speakers is a great way to start. You might also choose to add an amplifier or subwoofer — or both. All of these things, done together or on their own, will improve your factory stereo's sound. But there will always be something holding you back, and it's built right into the stereo.

Factory stereos have built-in sound shaping

Your factory stereo uses preset equalization designed to make cheap factory speakers sound better, meaning that it automatically adjusts the different frequencies, creating audio "peaks and valleys" which can degrade sound quality. It is particularly noticeable when you add amplifiers, speakers and subwoofers to your setup, as any deficits in the sound are literally amplified.

Most factory stereos also limit the bass output as volume increases in an attempt to protect the speakers. The trouble is, even if you upgrade your speakers and install an amp and subwoofer, the bass output is still limited by your factory stereo. This throws your system out of balance and makes the bass sound muddy and weak.

How can I overcome the factory processing?

Fortunately, there's an easy cure. You can install a sound processor, which strips away the sound-shaping limitations enforced by your factory stereo and sends a clean signal to your external amplifiers. The amps send the signal to your speakers and subs. Your reward will be resonant lows, sparkling highs, and a realistic sense of space and depth.

Are these sound processors complicated to install?

Installation generally isn't too difficult — these processors connect to your stereo using your vehicle's speaker wires, and then to your amps and subs. You'll be able to keep the look and controls of your factory stereo, but expand your system for serious sound.

Sound processor system diagram
  • A sound processor connects to your factory stereo through the stereo's speaker wires.
  • The processor removes the factory sound-shaping, so the signal is clean.
  • The signal is sent to your external amplifier(s). The amps power your front and rear speakers, and subwoofers.

Choosing the right sound processor

We carry a handfull of different factory sound processors, each with slightly different capabilities. Generally speaking, they range from "easy to use" to "seriously intense". Here are some examples:

JL Audio FiX 82 sound processor

JL Audio FiX 82 sound processor

Processors like the JL Audio FiX™ only require you to connect them to your factory stereo and aftermarket amplifier, then they do all the sound shaping for you. No hassles or tweaking needed — easy in, easy out.

Audio Control LC6i

Audio Control LC6i sound processor

For a more traditional approach, check out AudioControl's line of factory sound processors. They clean up the sound and give you manual control of the output for your amps. They're a particularly good choice if you have a premium factory stereo system. They can convert the amplified signal from premium factory systems so you can add your own amps and subs. AudioControl's line drivers can send a clean, 9.5-volt signal to an aftermarket amp, giving you clean sound. All their processors have highly customizable configurations.

Rockford Fosgate 3Sixty.3 signal processor

Rockford Fosgate 3Sixty.3 signal processor

At the other end of the spectrum are processors like the Rockford Fosgate 3Sixty.3. Once you've installed it in your system, run a USB cable to your laptop and and you can not only flatten the factory stereo's processing, but you can also use a 31-band equalizer to adjust the sound to your heart's content. The 3Sixty.3 is a hardcore sound-shaping toolbox for the serious sound tweaker.

Rockford Fosgate 3Sixty.3 control screen

From your laptop, the 3Sixty.3 lets you control every aspect of your sound system.

Keep the look, love the sound

For some car owners, radio replacement isn't a thing they can't do; it's a thing they don't want to do. And that's okay. With a sound processor, you don't have to put up with a lousy stereo just because you genuinely like the look of your car's interior or some of the infotainment functions. If you've tired of settling, give us a call and let us help you find a sound processor that's right for you and your car.

    I've added a monoblock amplifier and 2 subwoofers in a ported dual woofer enclosure to my 2013 Nissan Rogue with the Bose premium sound system by simply soldering a single RCA jack across the existing factory signal wires that go from the main amp wiring connector to the small secondary amp that's inside the enclosure that's attached to the spare wheel in the rear cargo well. My old amp was a Kicker DX250.1 which had a high/low level input switch. The switch didn't seem to make much of a difference but I think it sounded a bit better when it was set to the high setting. The amp always ran hot and I engaged the thermal protection circuit a few times when driving it hard for extended periods of over an hour or so, but I was driving a pretty serious 2 ohm load with it to a single 4ohm DVC. Now I have upgraded to 2 of those drivers and an Orion 600 watt amp at a 1 ohm load(1.3 actually). It sounds pretty good and has good bass and the amp runs quite a bit less hot and I've driven it pretty hard (max volume on the factory Bose) for extended periods of time without tripping any thermal protection circuits however the Orion amp doesn't have any option for speaker level inputs nor does it have a switch for high/low level input. All it says in the documentation is max input 5volts. But after reading this because a friend wants me to bass out his Altima coupe I'm curious to know if a sound processor would benefit my Rogue. I left the Bose intact and intend to cuz it sounds good.

    Ray, If you like the way your speakers sound, there is absolutely no reason for you to add a processor - which basically is used to improve the sound quality of a system.

    I have a car with a Harmon Kardon factory system. At this point, I've disconnected the factory "subwoofer" I use parentheses because it's just a 6x9. Anyway, I have a low-end sub connected to that output signal. It helps by adding some low-end bass, but definitely need more power. My question is whether I could connect a 2-channel line converter to that subwoofer output by essentially bridging the connection? Or, would I need to use the rear output signals to have a true left / right connection for the line converter?

    Buck Pomerantz from Crutchfield

    on 6/9/2021

    Joel, You really don't need a line output converter in your situation. You could install a powered sub or subwoofer amplifier that has speaker-level inputs and use the factory subwoofer wiring for inputs.

    I have a 2008 GMC Sierra Crew Cab. I don't have the factory radio installed anymore. I installed a pioneer radio. I'm looking to update my system I don't have Bose (front door speakers, back door speakers, pillar speaker). I already have a 10" Kicker under the passenger back seat that runs off of a Kicker CXA300.1 and a Kicker CX360.4 that runs the door speakers and the pillars tweeters. I want great sound, crisp sound, loud enough to feel it. Would like to install a Digital Sound Processor. Please let me know how to achieve this on my 2008 GMC Sierra. Thanks in advance for all your help in this matter. Thanks, Jesse Blewer [email address removed]

    I have an issue with a 2019 Mercedes sprinter with t a 7" MBUX radio i found out im pretty much stuck with, It only uses 3 speakers and sounds disgusting. most of the highs n mids run through a single center channel speaker while part of the mids and low ranges are in 2 speakers in the doors, My question is can any of these modules take the 3 channels i have and reprocess them into 4 speakers and a subwoofer output. I am really lost and disgusted that Mercedes wouldt go back to 1960's era single speaker in the dash setup and would appreciate any help

  • Chris from PNW

    Posted on 5/2/2019

    I have a 2016 Kia Cadenza that is sending too wide of frequencies to the factory separates up front causing some distortion. Plus the tweeters are just too tinny sounding. So I picked up some Infinity Kappa 60.11 CS 6.5" separates to replace the factory speakers as they come with crossovers which I figured might solve the factory stereo issues up front. After reading this article though, I'm now not so sure that's the case given whatever pre-EQ work my factory stereo is doing. I am trying to upgrade on a budget and don't want to purchase an aftermarket amp. the factory amp seems to put out enough juice as it is. Is there a DSP that will allow me to continue to use the factory amp?

    Buck Pomerantz from Crutchfield

    on 5/3/2019

    Chris, That's a great idea for a product; a DSP that works with a factory amp. I don't know that one exists. It would have to incorporate a vehicle-specific interface harness of some sort. The receiver in your vehicle, for example, sends only digital data to the amplifier, so interfacing with that may be impossible. Adding an amplifier with a built-in DSP may be your best solution. The new amp would get its inputs from the factory amp's outputs and mix the signals together to form a full-range stereo signal. Then you'd apply your tune-up via the DSP to get your high-fidelity sound.

    Arturo, Although it isn't easy digging through the settings menus and pushing the right buttons, that receiver has a lot of DSP features built-in, like graphic EQ and time-alignment, so you don't really need an addition DSP device.

    I have a 2015 buick regal. I wanted to keep the factory head unit and keep everything looking as OEM as possible without having any visible amplifier in the car or truck. I went with the small alpine ktp-445u power pack and Alpine R series speakers. I believe the 6.5 components are hooked up to 2 of the channels and the 6x9s are hooked up to the other 2 channels. The 3.5 center dash is left disconnected and the rear door 6.5s are hooked up to the head unit. I want a smaller sound processor that can fit easily behind the dash but I dont know where to begin and what one will work best for this application. Looking for suggestions on what processor to buy and what I should be looking to pay for installation. Thanks!

    I have a 07 Acura TL and Elliot Scheiner put a lot of work into tuning the factory radio. He did a great job and the stock system does not sound at all but it did need an enhancement. I'm into Sound quality now and I learned a lot about dynamic sound and time alignment along with floor level sound. I had my factory amplifier modified by a guy who changed out the passive capacitors and used muse amps to enhance the sound in my TL. I would like to know is there a way to use a high output converter to use on my factory amp instead of buying an aftermarket amp?

    Tim, A digital signal processor (DSP) can improve the sound in any system, especially one using a factory radio. Most are simple to install but very difficult to tune. Your installer should have a better idea of what specific processor to use to solve the issues he or she hears. And they should be familiar enough with the gear to tune it properly. As for factory subwoofers: they're highly sensitive, low-impedance (1 or 2 ohms) drivers powered by very small amplifiers. If you replace the factory sub without replacing the factory sub amp, you'll end up with less bass than before.

    I have a 2015 Dodge Ram 2500 with the 10 speakers I replace the door speakers with JL Audio 6 by nines I believe the two in the ceiling with Infinity Kappa and the front dash with infinity kappas. I use the factory amp for the kappas but the JL Audio I had a Kenwood Exelon put in in the issue is there they said I needed a sound processor to make them sound right. I'm not looking for top of the line but I definitely want something that in time maybe would be expandable. But yet something that has Crisp sound. Seems like I have a little bit issue with Bluetooth sometime not being loud enough to hear people. Would the JL audio sound processor be the easiest way to go yet have the quality that I'm looking for? Also the 8 inch sub in the rear is there a way to replace it with the factory amp that I can get some quality sound out of a speaker just putting in there some type of JL Audio or something of same quality? I have two 10-inch Subs with another amp but I was hoping maybe there was something to put in and replace that 8-inch some sub to make it sound good without going through the trouble of adding the subs I have now? Is there an amp that would work best to put in for the speakers in the dash and the speakers in the ceiling? Or what do you recommend so that they can keep up the power with the door speakers? Also is there a way to add a different 8 inch sub in the amp for the dash speakers in the ceiling speakers all in one so that I don't have to put in 3 amps.?

    I have a stock radio. I took signal from a rear speaker and sent it to an AudioControl LC2i for my remote turn on for an amp/sub-woofer set up. My problem is my factory radio heavily equalizes the signal(s) going to all speakers including the one i tapped for my remote turn. What can i use to get a clean signal from that rear speaker? Name of some brands/model? Also does the ACLC2i achieve this? In other words, I would like to kill the EQ or get clean/flat unequalized signal from my stock speaker to send to my ACLC2i > Amp > Subwoofer.

    T, Your stereo shop's recommendations sounds good, but I would add bass blockers to your door speakers to clean up the sound even more. Adding a sound processor and amplifier almost always improves the sound. And just because you add a sub doesn't mean you have to replace speakers.

    I have a 2013 Subaru BRZ Ltd. There's a rattle in the driver's side door and, in addition to applying Dynamat, the stereo shop recommended installing a subwoofer to lighten the stress on the front speakers. I was intrigued by this article and would like to get your recommendations for getting the best bang for my buck while keeping the head unit. Would a FSP help, and would I need to replace the factory speakers if I add a subwoofer?

    Nator, There are a couple of ways to upgrade the audio system of a vehicle which has a factory amplifier. One, as you say, is to take signal from the factory amp's outputs and send it to a DSP with speaker-level inputs. Another method is to employ an amplifier replacement interface, if one fits your car, that'll let you add your own DSP and amps while retaining all factory audio controls and features.

    Daniel, I know it wasn't talked about much in the article - dealing with factory tuning. A great way to get a flat, clean signal from a factory system is with a JL Audio FiX 86 processor and DRC-200 remote. You'll set your radio's volume at ¾ full and then control volume with the remote. The FiX processing automatically sums, EQs, and aligns the factory signals to a unified, flat stereo mix. Then you take the outputs of the Fix and apply your own customized DSP tuning and amplification.

    I have a general question about these DSP's... Once a factory stereo limits or cuts out certain frequencies, how are those frequencies restored, and are they actually fully restored? It seems to me that once they are limited and the sound is sent out in edited form they would be gone and lost for good. Can you further explain? I'm interested in upgrading my 2017 Honda CR-V in this manner, but I truely want full-range original sound and to make sure that is what I'd be getting with this purchase. Also specific product recommendations would be welcomed. I'll be running the signal from my factory touchscreen stereo, through the DSP, into an Infinity Kappa5 amplifier, pushing 4- Infinity Kappa 6.5's and 2- 10" Kicker CVT's. Thanks in advance

    Bill, I don't think there's any signal processing that can focus a musical image spread apart by the distance between tweeter and woofer. The remote knob that comes with the DQ-61 does more than just control the volume of bass - it's also used to make time adjustments. And if you don't like what the AccuBass circuit sounds like, don't use it.

    I have a 2017 Hyundai Sonata Sport and am keeping the stock HU (mine plays .flac files-thank you Hyundai!) and am thinking of using an AudioControl DQ-61, with either a Pioneer PDX-V9 amp or JL Audio RD900/5 amp. I own Focal ISS-165 components (tweeters will go in stock location, dash firing at windshield) and mid-woofers in the doors, knee level; Focal ISC coax in rear stock locations and a JL Audio CS112RG-W3v3 Subwoofer. 1) Since the mids and tweets are not near each other as is recommended, is there anything I can do with the DQ-61 or another processor, to digitally close the gap between the mids and tweets? 2) The processor and either amp accommodated a remote knob - do I need both or just one - which one? 3) I am concerned about the AccuBASS circuitry of the DQ-61 sounding artificial. Is that possible? I appreciate any advice you can give. Thanks!

    Hey Buck. I have a 2013 Nissan Rogue with the "premium" sound system. The sound lacks any punch and everything seems to come out of the speaker in the center dash. Not happy with the imaging at all. I was very upset to learn that with this system trading out amps and/or speakers can be very problematic. I have now decided that I would like to get a new amp(s), component front speakers, rear speakers and a new powered subwoofer. So everything but the head unit. My question is simply this, can I expect to get high quality sound with the use of some sort of sound processor to go along with everything else I am getting or will it be hit or miss?? And if yes, what should I get? Any help would be greatly appreciated.

    Mohamed, That receiver has so many tuning features, I doubt you'll need a separate DSP. Adding a DSP to a system will never improve its level of distortion. I think the Helix DSP Pro upconverts its input signal to 64-bit resolution and 96 KHz sampling rate.

    Hi, Do i need any DSP while i have Sony RSX-GS9 Headunit? Not for controlling the EQ or HPF or ... . Im thinking about the harmonic distortion and playing High Res. music files while im connecting my Headunit to my BRAX GRAPHIC GX2400 and BRAX 3 way Component Speakers with no phase Plug. And here is my biggest question, does these DSPies convert any low quality 16bit music files to 24bit or higher?

    Jim, I'm not sure the Honda receiver is as bad as you think, but you can remove all of the factory sound processing automatically with a JL Audio FiX 86 DSP.

    I drive a 2016 Honda Civic EX with a total of 8 factory speakers (4-6.5" and 4-tweeters). Sounds like a big bag of trash. In order to keep the HU and it's functions, I'm thinking of replacing the speakers (except for the rear tweets, probably just disconnect those) and adding the Alpine F300 to power them. I'm fairly certain that the HU is still going to hamper my sound upon completion. Do you agree and if so, which FSP would you recommend for me?

    Brentton, Check out AudioControl's DM-608, which has all its controls and adjustments accessible via PC, Android, or iOS device.

    Outside of the Rainbow DSP 1.8, are there and DSP options controllable and tunable directly from and iPad? Or Mac?

    Dave, Your vehicle is a particularly difficult one in which to upgrade the sound. One way would be to connect a DSP with speaker-level inputs and signal-summing, along with an aftermarket amplifier, that takes its inputs from the factory amp's outputs or right at the speaker connections. A great product for you to check out is Helix's P SIX DSP MK2, a powerful digital signal processor with a built-in six-channel amp. I don't know exactly what to do about the automatic noise control (ANC) in the factory system. Perhaps you could find out how to disable it in a Honda owners forum.

    I have a 2015 Honda Accord Sedan, 7-speaker system. I'd like to make audio system changes in steps. The first step I'd like to take is to add a DSP and disable the ANC. I'm hoping that this will make an improvement on it's own, but am concerned about the OEM amp un-doing some of the good that the DSP does to the signal. Will I need to replace the OEM 5-channel amp to see the benefit ?

    Jay, Almost any processor or equalizer can be used to improve the bass in a system. Maybe you should consider an AudioControl Epicenter. This processor restores and creates bass signals specifically for improved bass response.

    I have a 2006 Lexus IS250. I only have a 3 band EQ (Bass Mid Treble). I have a 500W kicker mono amp with 2 Dual 12 inch subs. Do you think a processor will give me deeper clean bass to my subs for them to hit harder with my factory stereo or should I go along with a in trunk EQ for stronger deeper harder hitting bass?

    Mike, To get great sound while keeping a factory system, you can use a sound processor that has speaker-level inputs, like Rockford Fosgate's 3Sixty.3 digital signal processor.

    Hello. I currently have a 1999 Lexus ES300 with the Pioneer factory stereo/amp/speaker/tweeter/sub setup. I plan to switch the stereo/amp to the Nakamichi ones and replace the OEM speaker/tweeter/sub with a Polk Audio set. I purpose want to keep the OEM head unit for the tape/cd to explain why I'm going that route. I'm wondering how I can incorporate a factory sound processor into that mix to add "oomph" to the Nakamichi stereo/amp?

    Gregory, There are a few digital signal processors that can solve your problems. For example, JL Audio's FiX 82 processor automatically removes all factory processing leaving you with a flat, coherent signal for your aftermarket amps to work with. An AudioControl DQ-61 can take your factory signals, combine them, and let you add you own EQ and time alignment for your amplifiers to then pass along to your speakers.

    I have a 2016 Tacoma double cab with the JBL system. I think it sounds muddy and bass heavy. It does have a sub and a reasonably powerful amp. I'd like to clean up the factory signal and increase the amount of equalization. Can I run some type of DSP or FSP that would give me a good signal but still allow me to use the factory amp / speakers? Then I could decide what speakers need to be replaced, if any, or what I need to add for amps. Or are there any amplified DSP's?

    I have a 2007 Chrysler aspen with navigation system, rear dvd player, all the bells and whistles controlled by the radio. I have a nagging volume limiter that constantly kills my sound when I'm driving. It never stays up at a satisfactory level unless its nighttime. Will a sound processor help me sir. I have an alpine factory system in my truck. It seems like every radio tech here in Michigan seems to think that there is nothing I can do about it unless I swap out the entire system compromising all my controls. I cannot do that, will you please help me with some honest advice. I would greatly appreciate it. The sound processor thing seems logical. I wander why no one has advised me to try that.

    I have a 2011 Yukon Denali with Bose premium system. I have upgraded and bypassed the Bose amp using Audiocontrol L6ci LOC Currently running kicker ix1000.5,( about to upgrade to Arc Audio 1200.6 amp ) Would something like an Audison Bit One or BIt Ten, or other like brand be an upgrade over the Audiocontrol L6ci and help better the SQ of my system and function as a LOC? Speakers in my system listed below- open to upgrades: 6.5" dsk hertz components in front, 6.5" RF Punch 3-ways in rear JL 12" 3v3 4ohm sub in rear- (sub is in small ( built to spec) sealed box. )

    Hello. I have a 2013 Honda Accord Sport. Factory 180w stereo. I installed Polk Audio Db6501 components in the doors, factory rear speakers, and I had a Pioneer GM D8601 amp powering 2 10" JL Audio W3s installed. I was thinking of adding a DSP and possibly an amp to power the Polk's. What would be a good DSP option? Also, when I turn my ignition off, a tone cones through my subs like a single bump. Will a DSP remediate this issue? Thanks in advance.

    Brent, Alpine's INE-W960 navigation receiver includes 9-band equalization and time correction, so you may not ever need an additional signal processor in order to get excellent sound. But if you're unhappy with the sound available, adding a digital signal processor to your system should enable you to attain the sound you want.

    David, I think any of the processors mentioned in this article might work for you, but not knowing anything about your vehicle (it's not available in the US) nor what processors are available in your country, I can't say for sure which would work best. For a novice, I'd recommend going to a local car audio shop and ask for their opinions and recommendations.

    CT, That receiver has all the digital sound processing you'll probably ever need right onboard, so any additional processor would be unnecessary. The DEH-80PRS' features include time alignment, 16-band equalization, and 3-way crossovers for active systems.

    Jazzy, The sound quality of almost any system will benefit from the addition of a sound processor. From your description, it sounds like your premium system changes tone as the volume changes. A processor like JL Audio's CleanSweep compensates for this effect, resulting in a flat signal that you can EQ to your own taste. Almost any processor will allow you to set the tone the way you like at the volume you like.

    Pavol, Almost all car audio systems benefit by the addition of an amplifier in musical clarity, energy, and loudness. While your sound will improve with the installation of those speakers alone, it will improve even more if you drive each of them with 50 to 75 watts RMS.

    Hi there, Considering to upgrade speakers on my VW Golf Mk7 with 2-way FOCAL Performance Expert PS 165F (both in front and rear doors). In addition the doors will be filled with three layers of noise blocking and anti vibration material (ZN FINISH and STP GOLD). I am concerned with the output of the stock Composition Media stereo (4x20w). Could you please give me an advice if the stereo's output will be appropriate in comparison with the speakers' output? Shall I rather go for lower Focal series as the factory stereo will not be able to utilize full 165F's potential? Or shall I rather buy aftermarket DSP/amp in order to match the speakers' level? My goal is just to have crispier sound at normal level of sound volume hence I believe that don't need high power output. I prefer to listen liquid drum and bass and house music. Many thanks and regards, Pavol

    I think your situation is pretty cut and dried, as far as the cost-benefit goes: if you change the stereo, you lose the navigation system, aux & USB inputs, and you have to hardwire all the connections. In my mind, that's not worth doing in a nice truck that has a pretty good factory stereo system. Maybe put in some aftermarket speakers (but make sure you get low-impedance speakers to match the factory speakers) or a subwoofer. Of course, using a factory signal processor changes that. You get to keep all the nice bells & whistles Toyota gave you in the dash, but replace all the other audio components with your choice of amps and speakers. Your truck is a prime candidate for this approach. Give us a call if you have any questions or would like some help selecting the gear.

    Highly considering an Aftermarket HU for my 2014 Toyota Tundra however my door lock,chimes etc maintenance, Navigation & personal reminders are all integrated into factory HU. Crutchfeild has several aftermarket HU choices BUT the dilemma is if I go that route how much of the those so called minor conveniences from the factory am I willing to lose, for example on my model if I forget to close the sunroof and exit the vehicle I get an immediate chime to remind me that it's left open. A minor loss if it can't be integrated into a aftermarket HU, but it's a major loss if it happens to rain & you forgot because of the former factory reminder. I think Crutchfeild will eventually do this but they or someone should do a item by item cost benefit analysis of retaining factory HU vrs aftermarket HU, not your run of the mill audio specs. As any respectable audiophile knows the factory DSP's is so choked down & unalterable that it's almost worthless to modify with add on's. I assume a aftermarket FSP would solve most of these issues but a real hard core test would be how much of a sound stage do you get vrs dumping the entire manufacturers system & getting a proven aftermarket HU with programable sound stage. I'd Like to hear from any Tundra owners that have done ONLY an FSP add on to factory & someone that went 100% aftermarket then have both list pro's & cons of their install & soundstage.
