Question about Jl Audio 12W3 Car Subwoofer

1 Answer

Subs sound terrible (Ive tried so many things)

First off I know its not the subs or the amp.... Hooked them up to a different car and they sounded GREAT. two different sets of amps and subs. ive tried 2 10 inch MA audio subs with a 800w Xplod amp and then two ten inch kickers with a 325w rockford punch amp). both sets sound fine in other peoples cars.
wire them into my Impreza and they sound like ****. more of a vibrating knocking instead of a low bass sound. Once in a while they will pound beautiful for like 5 minutes then go back. I've tried changing the ground wire, the power wire, and the two cords that plug from the deck to the amp, and the speaker wires that connect the amp to the subs. The amp POWER light IS lit.

Could it possibly be my battery? orrr.....

NO it won't be your battery. Sounds more like your deck.

Well i was driving one day and my subs just whent out so i bought brand new wires and hooked everything up but the power protector light turns red whenever uu turn it up past volume 10 i really do not know...


It sounds like your amp is going into protection. I know it's frustrating, but this is actually a good thing. If you subs you have are drawing too much power and the amp can't keep up, it will shut off instead of melting the board. Usually, the protection mode only last a few seconds. The user normally turns the music down that the protection shuts off and the music plays again. I recommend looking at a larger amp for your subs, if you are going to play them that hard.

I have an Alpine CDE-100 and when I hooked up my subs and amp I would only get subs with radio and regular speakers for my ipod via usb and the cd player? I had a friend that use to install sound systems...


While I don't know the specifics of this head unit, I would guess that it has settings that can be adjusted for each source. You might check to see if there's a menu that allows you to turn the subs on/off for the various program sources.

Hello i just recently bought alpine speakers for my eclipse 2003


mostly because the subs in the back are probley using more amps than the ones in the front in the front should be used mostly for vocals and your bass in the trun so maybe trying to unhook the ones in the front from the sub and just leave then hooked up to the cd player where you can hear the vocals really good and leave your subs in the back hooked up to the amp

Subs will not work right.


the subs coils are melted and shorting out so the amp shuts off

How do i make my two l5 10 subs sounds with clear


Try these:
Make sure the gain isn't set too high. That's a very common cause of distortion. You'll never want it set above 3/4 of the way to high. It will be a small dial on your amp marked "gain".

See if your receiver has a built in crossover on the channel your amp is hooked up to and set it so the cut off is at 400hz if possible. Meaning that the receiver will only send frequencies of 450hz or lower to your amp

Look on the amp for a built in crossover to the channel your amp is hooked to and set it to 450hz.

Make sure the cable that connects your amp to your stereo isn't running near any power cables of any kind because electricity running through a power cable can be picked up and then the sound it makes will be amplified, sent to your subs and cause distortion.

Make sure your amplifier isn't grounded to
your battery as this can cause what's called ground loop noise...also distortion.

Ground your amp as far away from the amp itself and your subs as the manufacturer safely recommends.

If none of those help then i'll try again :)

Subwoofers pop then immediately produce no sound


Sounds like the two subs wired together might be too much of a load on the amp and it is shutting off. Try wiring the two subs in series. That will reduce the load on the amp but will conversely put out less power. Less is better than none though. In any case check your amp to see what the lowest ohm rating it can see, that ohm rating is where you want your subs and if faced with a choice of either going under (lower numerically) or over (higher numerically) GO OVER!-it is much safer.
Here's an article I wrote that can help explain how to wire the subs to the amp.

OHM LOADS, SUB WIRING, OHM RELATED POWER OUTPUT

SERIES SUBWOOFER WIRING
Wire the positive pole from one voice coil (using wire that is as thick or thicker than your wire from amp to sub) to the negative pole of the other voice coil (on the same sub). This will leave you with a positive pole from one voice coil and a negative pole from the other giving you the two leads that will be hooked up to the amplifier or other subs. When wiring in series, the ohms will go up numerically, and the load on the amp will go down. Almost all amplifiers power output will follow this rule, except some amps such as JL Audio's “Ohm matching” D Class amps.

PARALLEL SUBWOOFER WIRING
Wire the positive pole from one voice coil (using wire that is as thick or thicker than your wire from amp to sub) to the positive pole of the other voice coil (on the same sub). Then wire the negative to the negative in the same way. You can then wire to the amp or other subs. When wiring in parallel the ohms will go down numerically, and the load on the amp will go up. Almost all amplifiers power output will follow this rule, except some amps such as JL Audio's “Ohm matching” D Class amps.

MULTIPLE SUBS USING SERIES AND PARALLEL WIRING
In order to match your amplifiers ohm rating you can use parallel and series wiring together, just keep things even for power distribution and to avoid phase issues.
Example: I have two “Type X 12” subs” that have dual 2ohm voice coils and have to match my “Amplifier X” ohm rating of 2ohms mono. In this case, I would wire each subwoofer in series (giving me a 4ohm load), and then wire the two subs in parallel to get my 2ohm mono load. When wiring multiple subs just, treat each sub as a voice coil and wire accordingly.

POWER OUTPUT AND OHM LOADS
For example if “Amplifier X” can make 100watts@8ohms, it would make 200watts@4ohms and 400watts@2ohms. However with every drop in ohms the amplifier is put under more pressure. It starts to create a lot of heat, distortion figures begin to climb, damping rates drop, and some amps even throw power spikes when clipping. SO BE SURE TO CHECK YOUR AMPS RATING AND DO NOT EXCEED IT!

Subwoofers were said to be bad


overpowered definitely. when you bridge subs your almost doubling the power. if the subs were set for 2000 then the guy he took them too should have known better or at least turned the power down on the amp.

Make sure that you have the subs wired in a 4-ohm series and not a 8-ohm load
