bad amp?
Wednesday, July 20, 2011 5:02 AM
Ok, I have the worst luck with audio... if I have my music really loud and when the subs hit, it cuts out.. I've been told its not getting the best ground but I still have yet to get a "good" ground yet then.... then yesterday while driving, music cut off, later revealing I blew my fuses in the amp. I looked everything over and was all good, but im still blowing fuses as soon as I plug them in. It was hot when I had checked it, not sure of it had overheatedfrom being used or just being in the car.. any help is appreciated.

Sorry if this is messed up, im using my phone..

if you're blowing fuses like that, there's a short somewhere. trace back on your power wire and check it for frays or pinch points.

A bad ground could also cook an amp, wires, or your neighbor's cat, which it looks like might be the situation. Like JL said, check your wiring, definitely clean up your ground as well.

I checked all wires, and didnt find anything... ended up redoing my ground, and hooked the amp back up, to find it smoking... so im assuming it was just the amp.. it was a cheap one anyways

sounds like the amp. but when you check wires make sure you check from front to back meansing pull the carpet up and check the entire length of the wire. not just each end. who knows it could have gotten pinched under the carpet somewhere and the jacket torn on a sharp piece of metal.

Yea, I took the seats out and pulled carpet up and followed the wire looking for any sign of it getting pinched or tore

Ok.. So I got new amps and now I've got the stupid engine noise throughout my subs, but its only those rca cables. I made sure its not interfering with the power cable. Could it be a possible bad rca?

bad ground is most likely. Where exactly are you grounded to? I know you swear the ground is solid, but is it bare metal and where exactly is it?

Its attached to the bolt for the rear driver side seatbelt buckle.. I ground all the metal around it till it was bare, including the bolt, then put a bare metal washer then the connector(forget what its called) then the seatbelt buckles on top of those. I don't believe its a ground because I switched the rcas between the two ams (speakers and subs) and it's appearing to just be the set of rcas meant for the subs, because it will make engine noise through the speakers if I connect it to the speaker amp

That's still a garbage ground dude. Those bolts are sandwitched in there. Drill a hole, grind the metal, bolt directly to chassis

that isnt the best grounding spot. the metal they use to beef up that bolt location is a poor conducter. sounds like you have narrowed the issue to an rca though time for a new rca.
