been doin car audio for 14 years still work in a shop and it sounds like the amp on car one is shot what ohm load is your sub wnd is your sub single or dual voice coil and what kind of am mono 2 chanel etc.

It sounds like the power wire has a short to ground. Check around wwhere it goes through the firewall, into the trunk, or anywhere the wire could be pinched or chafed. A bad ground is possible, but dosent explain the blown fuses. Check ohms between the negative terminal on the amp and a known good ground on the car. There should be zero (or VERY close to it)ohms. If you have a reading over .1, then you have a bad ground. Check ohms between the power wire to the amp and a known good ground (you should disconnect the wire from the amp first). You should have infinate ohms (no connection). If there is less than infinate ohms, you have a short to ground in the power wire. Also, check that your ground location is actually part of the main body of the car (I usually use a seatbelt bolt). Another thing...a system draws a lot of power. You prbably added somewhere between an 8 to 4 guage wire to the positive side of the battery. In order for the electrons to flow at the maximum rate, you need to add a same size wire to the negative side, too. It's the one in, one out rule. Run it between the negative terminal on the battery and a known good ground on the body under the hood. Keep this wire as short as possible.

he took the words right out of my mouth......... spoke in true car lingo.....

I agree with both ^^ post.... I have been doing car audio for 10+ years..


invest in a good voltage meter...

Nope, got my brothers car done though.

Yea, I'm thinking the amp is shot as well. I have no idea what the load is on my sub, I bought it used off of my cousin, it is a great sub though. It is an older JL 12", the kind that is all black with the large JL in white in the center. The amp is a P.O.S. no name 500 watt, 2 channel.

does the sub have 2 or 4 hookups on the back if you have a voltmeter just set it for ohms and test it that way we can let you know the proper way to hook it up and the best amp for it

Won't be able to do it for a bit, but I will let you know when I do...Thanks!!! I will bump this thread when I can do that...
