Our take on the Clarion SRV303

by Steven Johnson
Clarion

Who needs a powered subwoofer?

To produce bass, you need a sub, an enclosure, and an amplifier, and it can be little tricky to match them all up. A powered sub eliminates all the hassle, as the manufacturer designs the enclosure to house the sub and amp together. This all-in-one solution is especially useful in smaller vehicles, where there's no room to mount a separate amp, or in any vehicle where you need every bit of cargo space. Powered subs range from small, flat boxes that fit under your seat to larger boxes that go in your trunk.

Just want to add a little punch to your bass without a lot of booming and shaking? Clarion's SRV303 powered subwoofer combines a 7" speaker with a built-in 64-watt amplifier in a super-compact ported enclosure. It'll go places where a normal sub won't fit (under the front seat of your small car, for instance), and it'll add new impact and authority to your system.

The low-pass filter lets you adjust the bass to fit your vehicle, while the phase switch maximizes the sub's performance. You can hook up this versatile unit in any car, thanks to its preamp- and speaker-level inputs. And, if you like to adjust your bass on the fly, the control panel is detachable and comes with a 16-foot cable for remote use.

Better off without it

Written By Tobin, Tampa, FL on Sunday, September 10, 2006
Crutchfield Customer Review (What's this?)
 
I own a Subaru Baja and due to the set up of the car/truck I have extremely limited space to add a sub, basically 3" under the seats. Knowing I was not going to get much from a 7" sub I purchased it to slide under my seat figuring there was not much else I could do. Let me tell you now, I would have been better off without it. All this unit does is thud and pop. The sound quality is terrible and I have to turn the volume on it all the way down to even get a reasonable tone from it. My advice, save your money and if your strapped for space put the $250 into better speakers.

Be realistic

Written By Eleanor, Mass. on Friday, September 08, 2006
 
I read all the bad reviews on here and decided to buy this item anyway. Im glad I did. I think people are expecting to much out of this. It is a 7" speaker, this is not going to add a ton a bass to any car. I am running two of these in a 1986 Toyota MR2. They add a great amount bass in this little car. I also had only two 4" dash speakers so low end sound didn't exist before. For this car they are perfect. If you have a large car or mount this in the trunk you will be disapointed.

Getting the settings right makes a huge difference in the sound quality. I am running the crossover at a hair over 80Hz and the phase is REVERSED. Reversing the phase made the biggest difference. With it at normal the bass was very boomy and muddled. I am also able to set a high pass crossover for the 4's with the headunit. This prevents the smaller speakers from distorting when you turn up the bass. I have these set at 80Hz also. I wonder if some are cranking the bass for these subs and killing sound quality of the stock smaller speakers.

Clarion SRV303

Written By Dennis, Long Island , New York on Wednesday, August 16, 2006
 
Well.... first off I dont know if I should be mad or glad that I added some bottom to my system. For the price the unit costs it is alittle disappointing.

I can't trash talk the unit since I knew what I was purchasing...I read reviews and based on my knowledge due to size factor of the cabinet and fitting the amplifer that is low powered, but enough for what it does all into one housing that the bass wouldn't be great. My biggest dilemma is tailoring the sound to the cabin of the truck... you could get decent low frequency production that's a tad punchy, before the nitemare of any woofer that does not have enough space to have proper excursion. BOTTOMS OUT BIGTIME.

Second obstacle one must scrape clean is tuning the unit to another genre of music. Can not handle going from one thing to another at all, deffinently must start from scratch again playing around with all the adjustments. Well then again this is a subwoofer that is the size of a small boardgame box

Did you read the description???

Quote from Crutchfield's Overview: "Just want to add a little punch to your bass without a lot of booming and shaking?" and "It'll go places where a normal sub won't fit (under the front seat of your small car, for instance), and it'll add new impact and authority to your system."

This sub is meant for people that don't have a lot of room, like under the FRONT SEAT. It was not intended to be used in a trunk, you WILL NOT hear anything! This is not a sub to make your car rattle, it says that right there in the first sentence people! This sub was made to FILL IN your existing sound and for what it is, this is a GREAT product. A friend of mine has one behind the seat of his '04 Ford Ranger and it sounds great. No, his truck does not make your brain rattle. No, he can't set off car alarms. No, the cops don't look at him driving down the street. BUT, inside the cab, the bass is very full and even has a bit of kick to it. More than it did before he installed it.

Read what you're buying people!

Does what it says it will do...

Written By D, Grasonville, MD on Monday, January 09, 2006
 
I recently purchased the Clarion(SRV-303) for my 01 Tundra and must say at first I wasn't pleased with the result.. But after I tweaked the settings on the builted-in amp with the unit and tweaked the settings on my head unit for the sub woofer. It provided a decent sound for a variety types of music.. It really sounds good with jazz, r&b, old school music(oldies) and some hip-hop. If you happen to listen to alot of bassy music ie.. hip-hop and rap you will not be satified with this product. I basically see this product with music as a "Bass Filler" because it brings out the lows that your speakers can't hit and hold but does not over power your music with back breaking/rattling bass. Trust me you will definately not be setting off any car alarms with this speaker or be in any music competitions.

Has anyone informed Clarion HQ about this dud yet?

Written By H. W. Parkhurst, Eielson AFB, Alaska on Friday, November 11, 2005
 
I purchased a Clarion Pro Audio head unit from Crutchfield and was/am 100% satisfied with it. However, the 5-1/4" component speakers I also purchased craved much more power than the head unit's 18W x 4 channel amp put out. This is where I decided to maintain a Clarion theme throughout my truck. I bought a Clarion APA450 amp for the components and this so-called subwoofer. I installed the head unit and components in a friends garage but decided to have the amp and subwoofer installed professionally, no expense spared. I read all these reviews below my post
but decided to throw caution to the wind and use high-end amp wiring kits, RCA patch cables and such to ensure the quality that Clarion intended. I don't know if its the shoddy job that the installers did or if it is the SRV303 itself, but I am not impressed.

Look for other options if space allows

Written By Jerr, Sumner, WA on Thursday, September 15, 2005
Crutchfield Customer Review (What's this?)
 
Only if space does not allow for a larger subwoofer should this product be considered. Mounted in the trunk of my '03 VW Beetle 1.8T Convertible. Unable to notice any difference in deep bass at all, even while adjusting products volume control. Not recommended.

Worst item I ever purchased

Written By John, New Jersey on Friday, August 12, 2005
 
This is the worst item I ever purchased. This thing sounds like a tin can and worst yet the crackels and pops are unbelievable. You can't even tell it is in the car till it starts making horrible noises. I am not a kid either and I didn't expect it to boom, I expected some added bass to compliment the music... not what I got. I didn't buy from crutchfield which is my loss because the company I bought it from has been giving me a hard time for months on returning my money even though I returned the product

Clarion SRV303

Written By Curtis, Tulsa, OK on Sunday, July 31, 2005
Crutchfield Customer Review (What's this?)
 
If you're looking for convenient way to add a "fuller" sound to your system the SRV303 will do an okay job--just keep your radio presets to "easy listening". You will in no way get a "punch" or "hit" from this unit. If you increase the volume past what grandma would normally use, you'll get a "thwap" or a "blat" sound. This unit will bring out some lower frequencies you may not have heard before, but that's about as exciting as it gets. I tried it for THREE months, tweaked every setting, and too bad Crutchfield's return policy is only 30 days. This baby is goin' on eBay.

Jeep Wrangler - Perfect Match

Written By Mark, Thomaston, CT on Monday, June 20, 2005
Crutchfield Customer Review (What's this?)
 
I had been searching for a compact sub for my Wrangler simply for the ability to hear my music while driving with the top down. I also have a Clarion ProAudio head unit so connecting the 2 was very easy. After the installation, I was able hear the bass when driving with the windows open or the top off.

I gave this sub a 4 star rating because it was exactly what I wanted. A sub that fits (perfectly) under my front seat, so it doesn't take up what little cargo room I have. This sub will not blow your windows out, but it will give you the little extra bass for a very small footprint. Had the price been a little cheaper I would given it a 5.

Very Disappointing

Written By Jeffrey, Friendswood, TX on Tuesday, May 17, 2005
Crutchfield Customer Review (What's this?)
 
I was looking for a simple and (relatively) inexpensive way to fill in the lower bass frequencies with my factory system with aftermarket door speakers. After doing my research and reading several reviews, I decided on this Clarion powered sub. Several people had written that this was a good choice for filling in the low frequencies with a factory system, and were really impressed with the sound from such a small unit. The few bad reviews seemed like they were from kids who were expecting to win a stereo contest with this thing.

So, I ordered it and spent the good part of a day installing it under the passenger seat of my Tundra. I finally turned it on to hear the fruits of my labor, and what I heard sounded like a blown speaker. If I turned up the volume and/or gain enough to even hear a difference in the bass, the rock bass drum hits in my "test song" (Rush's "Territories") caused the unit to make a "bwop" sound. I called tech support and tried a few adjustments, but to no avail. They even were gracious enough to send me a replacement just to be sure I didn't get a defective unit, but the replacement sounded the same. The bottom line is that this thing just can't handle much volume at all.

Perhaps mounting it under the seat in my truck caused too much sound to be absorbed, requiring more volume than other people needed in their vehicles. Or, perhaps my aftermarket speakers (Polk 6.5") already put out better bass than the other reviewers had from their factory speakers, causing them to hear more of an improvement. For whatever reason, I was extremely disappointed with this product and was glad Crutchfield has that return policy.

Decent sound in a compact box

Written By Brian, Lynnwood, WA on Saturday, April 30, 2005
 
I'm shocked at how many people are installing this sub to magically improve their factory systems. NOTHING is going to make a factory system sound good! If you've installed aftermarket systems before, you should know this. I've installed three systems now and they have all drastically out performed the factory units that were in before them. Now let's talk about this Clarion sub. If you are short of space in your vehicle, this could be the sub for you. I decided to install it under the front passenger seat of my Subaru. I hooked it up using a patch cable, not the speaker inputs. When I first heard the sub, I was less than impressed. But after some adjustments to my Alpine unit and to the sub itself, I was able to get a pretty good sound out of it. This sub will give your system more of a "full" sound, so don't expect it to rattle the neighbors' windows, because it just won't do that.

Pure disappointment

Written By dj strict, Saugus, MA on Sunday, April 17, 2005
Crutchfield Customer Review (What's this?)
 
I have been working with car audio professionally for several years, and was excited to see the release of such a space-saving product with a decent power rating. Aware that this subwoofer wouldn't sound like the Earth rattling system I had as a teenager, I bought it simply to add another chunk of thump to my Jeep's factory sound system. Reading some good reviews, I thought "Great! Now I can add some bass and keep all of my cargo space free!" When I read some of the poorly rated reviews, I figured "Eh.. it's probably some young kid who was expecting the thing to sound like two 12" DVC subs." So I thought about my needs, and went for it. After the relatively easy installation, everything looked beautiful... and then I turned it on. The bad reviews suddenly popped into my head. WOW - What an extremely misleading, innefective, poor design. As one previous posting mentioned, nice sounding low frequencies at low levels, but when you give it even a slight amount of decent volume, the entire unit would crap out, distorting or weakening in power, and creating an obnoxious rattle from the unit itself. I tried to tune it and work with it several ways, but found myself on the phone calling for a return authorization 30 minutes later. As I mentioned, I speak as someone who is capable of producing a knowledgable car audio review, and if the scale goes 1 (poor) to 5 (best,) I give it a flat 0. I suggest viewing any other options before purchasing this powered sub.

Sub for Ram Trucks

Written By Keith, Atlanta on Friday, March 18, 2005
Crutchfield Customer Review (What's this?)
 
I purchased this same sub 3 years ago when I bought my new 2002 Dodge Ram Sport and it fit perfect under the rear seats. It was just the extra bass the factory Infinity system needed. About 2 mo. before I put it into my new 2005 Ram 1500 with Infinity, Nav. and Sirius, it started rattling like it was blown. Wore-out. So I'm buying another one. Good sub.

Clarion SRV303

Written By Steve, Millis Ma. on Sunday, March 13, 2005
Crutchfield Customer Review (What's this?)
 
I purchased this for installation in my 1966 Ford Galaxie convertible. I have spent the last 3 years restoring the car, and I wanted music but with out cutting up a 38 year old interior. I went to great lengths to hide as much of the music system as possible, and when it came to a sub woofer, I didn't want a box in a truck which I had spent hours detailing to look origional. This unit was perfect and added a great depth of sound missing with just the combination of mid range and high speakers. Installation was easy, placing it under the passenger seat, and the sound greatly inhancing the low range. I listen to mostly 60-80's pop music, and I am satisfied with the sound quality and the packaging of the unit. I plan to install one in my 04 Tahoe next.

Calrion Powered Sub

Written By Benjamin, Mobile, AL on Wednesday, March 09, 2005
 
I had this installed with my Alpine stereo at a professional installer behind my seat in my Mercedes SLK32. When they finished they said it was dissapointing after they tried tuning it a number of ways. I worked with my equalizer and down tuned my mid and treble controls. Also I set the gain to max and the 70 by pass setting. Then I set the subwoofer gain in my stereo and it works great. When rap or hip hop is on it will blow plenty of air and sounds good with the top down too. I suggest working with it, since it is not 3-10" subs with a 400 watt amp.

HMM

Written By Steven, TN on Wednesday, March 02, 2005
 
The previous review on this product should be ignored all together. There is no possible way you can tell what this product can do with a factory stereo. It just wasnt made for that kinda thing. I have installed several systems in my vehicle and others so I know what I'm talking about. Get a stereo with a little more kick and a little more options to control the sound and I'm sure it will sound just as good as any other small powered sub!

Clarion sub

Written By Steve, Pleasanton, CA on Wednesday, March 02, 2005
Crutchfield Customer Review (What's this?)
 
When I first read about this product it sounded very impressive, unfortunately the article was the only thing impressive about it. My infinity perfect 6.1's located in the doors of my 1994 Viper put out almost as much bass as this unit but did so in a clearer more percise fashion. The more I turned up the gain the worese it sounded. I tuned it for almost an hour before I threw in the towel. Thats just my 2 cents. I hope this helps.

buy something else

Written By Eric, Rockton, IL on Sunday, February 20, 2005
 
I bought this unit thinking I could keep the factory stereo, stuff the unit under the drivers seat and get some extra bass fullness to my 2002 Civic's stock stereo and aftermarket speakers. I used the speaker level inputs and hooked it up as directed. It powered on but I couldn't hear it, so I adjusted the gain up from minimum, I could finally hear it at about 1/2 gain with my ear on the unit. It wasn't what I was hoping for, so I turned it up to full gain and it sounded like absolute crap, just like someone beating on a large drum with rusty sides that fell apart as it was beatin on. This is by far th poorest excuse for a subwoofer I have ever heard. No matter how I adjusted the settings, it either couldn't be heard or sounded terrible. Removing from the car altogether and turning up the bass on the head unit and adjusting the fader to be more on my 6X9's in the rear proved to provide a much more enjoyable listening experience. I was impressed by the small size, but have learned that age old saying, if it seems to go to be true, it usually is. Do not buy this unless you were gonna just through that money in the fireplace or whatever. You'd be better off installing an empty 5 gallon bucket in you car and beating it with a wooden spoon to the beat of the music.
