Question about Car Audio & Video

1 Answer


Basically i got a amp and a sub the other day and fitted it in my car. everything was working, but i notcied little sparks from the wires at the back of the amp (when you moved it abotu) because it would sometimes touch each other (the red wire and the black wire) the subwoofer used to go out randomly sometimes and come back. anyway today the subwoofer stopped working altogether but theres still power in the amp because the green light comes on which means the amps ON, but still nothing comes from the sub. I checked all the wiring and it looks correct. from grouding, to remote cable... everything seems in order. anyone know whats wrong? I have 2 12s in my car (07 suzuki sx4) well one went out when i was bridging them it just wouldn't come back on (my fav. box/speaker too I made it myself.:-)..) well then my only 12 left would go out some, usually due to the ground was lose.. I've checked all the wiring fuses and ground shows nothing wrong. amp is getting power but sub isn't working. My fiance does the work must the time, but he in out of town. I'm lost on what do to now. (I know how to wire and car stuff even tho i'm a girl so don't try that comment lol I've done my strobes, neons fog lights all that) any suggestions thanks!!

I would say that you blew a capasitor on the out take of the amp. All the green light means on the amp is that you are getting power to it, not that it is working properly. If this is the problem it is because you probally tried to bridge a non bridgeable amp. This problem occurs when an amp is not ready to take the 1 or 2 Ohms that come back through it and it blows this little ***** capasitor inside rather than frying the amp, again if this is the case you should be able to open it up and see the one that you have blow. If this is the case get a sodering gun and take the capasitor out, but make sure you mark the - side so that you will know which side to put where (it will be the side with a  different color line on it). after that take the piece out to a radio shack or another electronics store and tell them you need that exact piece. After that just soder it back in and see if it works, if it does great if not ..... it is like a $1 part and you can't break something that is already broke. oh and if it does work .... don't bridge it again XD

Hope that helps :)

I have a kenwood KR-V8080 and i had 4 subwoofers hooked up to it. then one day it jus shut off an smoked a little. now when i turn it on an try an hook up speakers it sparks an the speaker pops. i dont kno...

You blew the amp. If you were running 4 subwoofers off of a dual channel amp you most likely running them bridged off of two different outputs. You most likely blew the resistor and because it was pushing more power then it could handle. Also when you bridge speakers it brings down the impedance which allows for the more power to course through. Suggestion is to buy a new amp that can handle 4 subs or 2 different amps for both sets.

I got a 10'' alpine type r subwoofer and it was plaing but it just quit working the speaker is not blowed up it is still brand new but what could be the problum it just wont come on and play

some times you cant visually see if a speaker is "blowed up". Many times (especially with new subs) the voice coil can burn out due to being worked too hard, too much voltage, or too little voltage. most manufacturers recommend not using the sub at max for several days to brake it in. that said, check (with an ohm meter) tho see if it has the proper resistance flowing through the sub. Next i would (assuming you have it hooked up to an amp) check the amp and make sure it is functioning properly...

Sub cutting out

Check the 12v wire running from the battery to the amplifier. Also the sony explode is a garbage subwoofer compared to the Alpine.. sony (they say 1200w max but its more like 100w to power the thing) Amp could be going. Is the amplifier hot when running. If there is a burnt smell comming from the amp, its the amplifier

Low output on subwoofers

You may have wired the sub backwards or it could be only somehow hooked into one channel instead of 2. I think this is a wiring problem.

Wires on SUB - Make sure they are connected correctly
RCA leads to AMP

youll need distribution blocks for second amp.this is the basic solution though.other things like wire guages,amp power and crossover settings need to be considered.

if you have real old wires from the amp to the sub try getting new wires on it. check the little wires that go to the cone itself on the sub. sometimes they can manage to get pulled out of their terminals and make sure that thier touching the terminals on the correct spot
