Car sound system. only sub is giving off sound. other 4 speakers dont work at all

Hi. please help me if you can. ive been asking everyone i know for help and nobody seems to know, even mechanics!

the problem is in my jeep wrangler only my 10" sub is giving off sound and its all bass so you cant hear any high sounds that the regular speakers usually give off. I installed the system myself. I have a kenwood stereo, dub 550w mosfet amp, 4 sony tweeters and 1 10" mtx sub. They all worked at one time but the past few days either they worked or didnt and now they dont work at all, just the sub. The sound is very bad as its only a deep bass sound. I tried playing around with the settings on the amp but nothing works.. the crossover settings dont work, the frequency range doesnt work... or should i say doesnt make the tweeters work. I can rule out that it is not the amp that is the problem because I went and bought a new amp and hooked it up today and that didnt work, it was the same as before so that is not the problem. Please help!!!

Could be bad outputs from the back of your head unit or also could be bad rca cables. Make sure the amp is on and powered.

Check setting on the head unit if you have SUB settings. Make sure amp is bridged running 1 channel combined not 2 seperate, Make sure RCA leads are plugs in correctly and not backwards, turn do the power on your amp, turn SUB volume down on your amp.

I just needed some help with wiring my p8002 rockford amp to 2 fosgate 10 inch subs i just bought. there 4 ohms a piece and dual voice coil. i dont know much about car stereos but people keep telling me...

Well i tried looking up that amp, but Fosgate sight is down. So assuming that the best power out of your amp is 2ohms off the bridged hookup, and the subs are 4 ohms per coil, the best way is to only use one side of each speaker and hook it straight the the bridge. Only using one hook up wont hurt anything, its just for giving you wiring options. And when adding up ohms of speakers, it goes like this. If you had two 4 ohm subs, that'll give you a 2 ohm load. If you hooked up all your hookups, it would be like having four 4 ohm subs, and would give you a 1 ohm load.

if you dont have a crossover you will not get the best performance out of your sub. you need to seperate the frequencies and send only the lows to the sub woffers.

Hello empsglen,

If the sub voice coil is open, you will get exactly no sound. No crackling, nothing.

Use a multimeter to check the sub voice coil. If the meter reads infinity, the coil is open and to the amp, it's as if there's no sub connected, and you will need to replace it.

Hope this helps.

SWR-1242D wired at 4ohms


Having to much power for a subwoofer is a veeeery good thing, it will provide a lot of control and quality sound to your sub.

But this sub is a dual voice coil at 2 x 4ohm so if you want to hook it up at 4 ohm u need a 2 channel amplifier running mono mode.

i dont recomend that you hook up in 4 ohm, its better to take some time adjusting the levels on the amp and the headunit.

This system has the potential to create a realy good bass sound if u tune it the right way.

No sounds through sub and rear speakers

Your radio probably has a sub on and off function on it that was reset when it lost power. Go into your setup menu to turn it on.
