About the Scosche LOC90 Speaker to RCA Line Output Converter

Converts speaker-level signals to preamp-level

Scosche's LOC90 line output converter transforms high-level speaker wire signals to a set of line-level RCA outputs. If your car radio doesn't have preamp outputs, this 2-channel converter lets you tap into speaker wires to send up to a 4-volt signal to the preamp inputs on your 2-channel or mono amp.

Converts speaker-level signals to preamp-level

Scosche's LOC90 line output converter transforms high-level speaker wire signals to a set of line-level RCA outputs. If your car radio doesn't have preamp outputs, this 2-channel converter lets you tap into speaker wires to send up to a 4-volt signal to the preamp inputs on your 2-channel or mono amp.

The converter will turn on your amp when it senses an incoming signal, so there's no need for a turn-on wire. If you're installing a subwoofer, the package includes a wired remote control for adjusting the bass level from the front seat.

Great product

Ivan from Sparks, NV on 7/25/2019

Verified customer (What's this?)
Verified employee purchase (What's this?)

At first I was skeptical of this product but now I'm a believer. I made a mistake though. So I fallowed the instructions and tapped into my rear deck 6x9 's. I hooked up the amp and away I went bumping down the street. But it just didn't sound right. What I learned is, in my 2005 Chrysler 300c, there must be a crossover that blocks low end frequency on the rear speakers. So I disconnected the LOC from the left and right 6x9' s and tied the 2 LOC channels together and tapped into my factory subwoofer instead. Wow! Night and day difference. So if you have a car with a factory sub. Tap into that instead of the rear left and right speakers. Also, for me the remote turn on works like a charm. I see in YouTube videos people say you don't need to connect the ground wire. That couldn't be further from the truth. I give 4 stars because both white wires looked the same. No negative strip indicator.

Pros: Works as advertised

Cons: No negative wire indicator on white wire.

Used to take RCA speaker inputs back to new subwoofer. Easy to install. Remote turn-on wire didn't work but that may have been a bad connection that I made. Luckily the audio sensing turn on feature of my amp works very well. I will troubleshoot the remote turn-on wire at some point. The remote gain control made the tuning process easier to make sure the signal being sent to the amp was loud enough without adding distortion to the signal prior to amplification.

Pros: Easy to install, good instructions, clean signal

Cons:

Perfect LOC

Chris from Jackson, MO on 9/12/2018

Verified customer (What's this?)
Verified employee purchase (What's this?)

I decided to use the LOC90 instead of others mostly based on the reviews and price. I didn't want to spend $100 but I didn't want to spend $10. This line converter does not disappoint in any way ( maybe wire length). Easy to wire, remote turn on, and easy to hide. Highly recommended.

Pros: Easy to wire, remote turn on, compact, and powerful.

Cons: Power, ground, and remote wires could be longer.

Good product, works as expected.

Steve from Hopewell Jct, NY on 1/8/2018

Verified customer (What's this?)
Verified employee purchase (What's this?)

Works as expected. Used this LOC when adding a subwoofer to my stock Jeep stereo system w/ stock head unit. Easy to tap into speaker wire, used T-connectors and didn't have any problems. I like that this LOC has a remote lead so I didn't have to find and tap into a remote wire elsewhere. I set the two level adjustments to 1/2, and I did not use the remote knob. I am able to make all of the adjustments I need from the sub woofer downstream. Thanks Crutchfield for the recommendation and the guidance with matching the LOC wires to my Jeep's speaker wires.

Pros: Easy to use, compact. Simple solution to add a sub or amp to a stock head unit.

Cons: Build-quality seems light and cheap but it still works as expected so I guess it doesn't matter.

Works well was easy to install. I had am issue figureing out the polarity of the wires comming off a factory sub. 5 mins total time on the phone with tech support and i was hooked up and happy. The remote wire dosent seam to work hence the 4 stars. As always im very pleased with Crutchfield. The free tech support is worth hundereds. Dont be afraid to tackle a sub amp upgrade with thos product. My girlfriends car had factory navagation and she wanted to jeep her factory setup she just wanted real bass. This product fit thr bill perfectly. With a 5 min phone call everuthing went perfect. Than you Crutchfield. I wish i could rember my techs name but i cant. Keep up the amazing customer support

Pros: Worked great has remote gain control so u dont have to "bump" all the time. Small easy to hide easy to hook up. Tech support is amazing

Cons: Couldnt get the remote turnon to work but could have been a bad conection on my part. The box was already hidden anf i didnt feel like traring the trunk pannales out again so i just ran a mew wire off the fuse block.

Want to talk about bang for your buck! This product provides everything one needs to add an aftermarket sound system to your factory head unit. It even provides it's own remote wire which is just fantastic and saves one the trouble of having to use a multimeter to find an accessory lead. There are other products are on the market that start at $150-$200 but this is a no-brainer I would highly recommend this product.

Pros: Small size, provides own remote wire, super easy installation.

Cons: None

Superior L.O.C.

Ben from St Charles, MO on 12/20/2016

Verified customer (What's this?)
Verified employee purchase (What's this?)

Replaced a very cheap line out converter with this one and I am amazed at what a difference it made. Virtually zero feedback and great signal strength with plenty of adjustment. Easy install especially if you can tap into your rear speakers and run the 12v, remote and ground directly to the amp (although probably less feedback with a seperate ground). I am very happy I purchased this product.

Pros: Wiring instructions were simple and easy to follow and the wires were easy to distinguish between (I am a little color blind so this was a big help). Compared to the non-adjustable version from another manuf. I used before this one is 100X better.

Cons: Not enough double-sided foam tape included to mount the LOC itself; although there was some included to mount the bass boost knob. Very minor issue and would in no way keep me from suggesting this product to others.

Adjustable controls Should make adjustments...

Mike from Chandler, AZ on 11/11/2016

Verified customer (What's this?)
Verified employee purchase (What's this?)

As a simple Line output converter it works well. The adjustments on the unit itself work. However they used the wrong range potentiometer on the remote adjustment because only about the first 10% of the dial rotation makes any adjustment, which is why some reviews have said it is on or off. Don't plan on being able to adjust your sub on the fly for each song because it simply doesn't work. I'm sure Crutchfield would happily take the product back but now i have cut into my factory harness, soldered heat shrunk and mounted into my dash the remote wired through my dash and the entire dash put back together so it's not coming out. I'm a little disappointed to get a faulty product from Crutchfield, but i'm way disappointed sosche didn't do their homework and make sure the thing works. but I guess that's what you get for the price.

Pros: Great unadjustable LOC, simple install

Cons: Adjustment knob is useless

nick from Maryland on 6/21/2015

Verified customer (What's this?)
Verified employee purchase (What's this?)

good product except if you have a digital head unit. if you do its not compatible and the remote wire will sometimes fire and sometimes not, only turning your amp on or off some of the time. you need to run your remote wire on your amp to a not continuous power supply on your fuse box and bypass the remote wire on the LOC. a small hassle but an achievable obstacle

Pros: the remote gain is convenient and price is cheap

Cons: the compatibility problem discussed in the review

Features

Line Output Converter: The Scosche LOC90 Line Output Converter converts speaker wire (high-level) to RCA outputs (low-level) for the purpose of adding an aftermarket two-channel or mono amplifier to an existing factory or aftermarket stereo system which lacks low-level outputs. The LOC90 features up to 4 volts output and works with high power car stereos up to 50 Watts (RMS) per channel.

Wired Remote Control: The LOC90 also includes a convenient remote mountable volume control for precise control over a subwoofer amplifier's volume level from the front of your vehicle. The wired remote is fitted with an attached 17' cable terminated by a right-angle 3.5mm male connector which plugs into the LOC90's minijack (3.5mm) remote input. The wired remote control is designed to be mounted under the dash using the included 3M tape or two self-tapping screws.

Connections: The LOC90 features four speaker level input wires and a stereo line-level output. There is also a +12V power wire, ground wire, and turn-on lead.

  • Speaker Inputs: Connect the left (+) speaker wire of your car stereo to the white wire of the LOC-90 and connect the left (-) speaker wire to the white/black wire of the LOC-90. Then connect the right (+) speaker wire to the gray wire of the LOC-90 and connect the right (-) speaker wire to the gray/black wire of the LOC-90.
  • RCA Outputs: Connect the RCA output jacks of the LOC-90 to the RCA inputs of your amplifier or EQ booster (Red = Right, White = Left).
  • Power/Ground: The +12V power wire (yellow) must be connected to your vehicle's constant battery power, while the ground wire (black) needs to be connected to your vehicle's metal surface.
  • Turn-On Lead: Signal sensing turn-on lead (blue/white) for aftermarket amplifier turn-on.

Output Level Adjustment: The LOC90 Line Output Converter is equipped with output level controls that can be adjusted for proper sound level matching. This done by inserting a small flat-blade or phillips-head screwdriver into the gain adjustment holes, located on top of the LOC-90. by turning clockwise, the gain for that individual channel, or the amount of sound allowed to pass through the LOC-90 is increased. By turning counterclockwise, the gain for that individual channels is decreased. If you feel that after increasing the volume of your stereo, the sound is too quiet, then equally increase both the left and right gains of the LOC-90 until the sound level is adequate. If the sound level is too loud with only a slight increase in stereo volume, or distortion (poor sound quality) is noticeable, then equally decrease the gains of the LOC-90.

Dimensions:

  • Line Output Converter: 2.1875" (w) x 1.125" (h) x 3.5625" (d)
  • Wired Remote Control: 1.9375" (w) x 0.875" (h) x 2.875" (d)

Q
Does this act as a low pass? I have a factory sub that doesn't have a crossover so connecting just the RCA out to the harness causes highs to go to the sub. My head unit doesn't have a sub out, with this do the trick?
[ Devon  Jun 30, 2019 ]
2 answers
A
your question is a bit confusing. this does act as low pass for cars without rca outputs and without a factory subwoofer. if your car already has a factory subwoofer and you are trying to steal that signal from the plug this product will not work. you will need audiocontrols lci2 to convert that factory sub signal into something your new amp and subwoofer will like.

Q
i have a 2018 honda accord. how do i figure out which rear speaker wire color is positive and which 1 is the negative ?
[ shahan  Mar 30, 2018 ]
3 answers
A
Set a multimeter to measure DC voltage, and touch the speaker wires to the probes. If your probe is touching a wire with an opposite polarity, such as the positive probe to a negative wire, you will get a negative numerical reading. Try switching which probe you're using to get a positive reading instead.
[ Codi  Mar 30, 2018 ]
A
Use a multi meter to check the output. Set it on 12v and put the leads on the speaker terminal. If it doesn't read with a minus in front of the voltage then the red lead will be the positive and the other the negative.

Thanks for your question. For information on amp control I would recommend reaching out to an Advisor by phone (1-800-324-9695) or online chat. They will be able to discuss how your current system is set up and if it is ideal. They can make recommendations as well to keep your system running trouble free.

The Scosche LOC90 has a signal sensing turn-on lead (blue/white) for connecting an aftermarket amplifier remote lead--this will automatically turn your amp on when a signal is present to the high-level inputs on the LOC90 and then turn it off when it stops receiving a signal. I hope that helps. My Bio: http://www.crutchfield.com/Support/Bio.aspx?bio=159

I installed this LOC in my Silverado because I wanted to add a sub and amp and still use my factory radio. My question is when adjusting the input sensitivity, would it be better to start with the amp or the LOC?

I just set the loc at like 3/4 on the 2 flathead screw gain adjustment. I left the " bass " knob off. Then did a standard tune with the sub amplifier. Sounds great.

I would start at the converter. I set my converter around 75% and then gradually set the amp. Hope this helps
[ jon  Nov 12, 2015 ]

I would leave it in the middle just like plugging your phone to your radio if the volumes to high on the phone you will get distortion try adjusting the amp first might be just enough.

How long is the remote turn on wire?
[ Evan  Sep 18, 2015 ]

About 1FT. Short but if you just add a crimping sleeve and pinch it you can always add more wire to suit your purpose. I installed it in a friends car about 4wks ago, NO ISSUES works great! I would buy this unit again for a factory radio install.
[ Dennis  Sep 21, 2015 ]
A
I would say about 8 inches which is the same for all wires leading off. Definitely not long enough to be routed anywhere but long enough to tap directly into some rear speakers or harness behind stock HU.
[ Jesse  Sep 20, 2015 ]
A
Short... i think less than 12 in. ... plan to match/ have equal distance for remote wire same as rca's. So pan to extend it unless/ if you wire it right next to the amp. Meaning if you want to hide the LOC and need 5ft length for rca, get 5 ft of (blue)remote wire Also plan to get wires to run 1. power and 2.ground + 3. a fuse... (for 12v) I bought 6 ft. long red/black/blue 16 guage. This device requires 12v power & ground. You should * fuse the 12v - 5A is enough. You could probably use 18 -20 guage.
[ GREGORY T  Sep 18, 2015 ]
A
its pretty long. I don't know the exact length but I would say at least 4-5 feet long.

ake signal from right(+ & -) and left speakers(+ & -) connect to loc... 1. now run 12v power from battery (w/fuse) 2. Run ground. Now you plug rca's into LOC and connect remote output to the amp. Adjust the LOC... done :)
[ GREGORY T  Sep 18, 2015 ]
A
The converter wires to you factory rear speakers and is also your remote power.
[ mickey  Aug 27, 2015 ]
A
You splice the box's wires in line with the radio's output wires. So you can splice this product in at the rear speakers or directly behind the head unit. There is also a nice option with this that splices 12 volts power in so you can have your amp's remote spliced to it instead of all the way back to the head unit. When it receives a signal from the speaker outputs, it will put 12 volts on the remote wire and turn your amp on.
[ robert  Aug 24, 2015 ]
A
You can tap into the rear speakers in the rear or just behind factory head unit. Either way works fine. Converter works great. Also has remote turn on built in. If you use the included bass knob you'll have full control at your fingertips. Just make sure you ground converter.
[ jon  Aug 23, 2015 ]
A
Uu got it. Rear speakers, just as the instructions suggest. I used the rear power point (cigarette lighter) for the power source on the converter is an all time power. So you don't need to have one that turns on and off for the converter to dignal the amp to turn on. Remember, with this converter there is NO need to take the dash apart.
[ Evan J.  Aug 23, 2015 ]
A
If your installing the amp in the trunk the rear speakers are you best choice for source for input. This item requires two speaker level input a 12v input and a ground. Fron this it will give you two rca outputs and a 12v remote output.
