my borther has a denali with some cerwin vega 15 woofers and three tvs set up inside his truck. he is runnig 0 gauge wires for positive and ground but on the side where the positive connects to the amplifier, which is a boss 3000w, the connection seems to be melting whenever he is really bumping the system. So any suggestions as to whether wat it could be any help would be appreciated>>>???? thanks

 

what size fuse is he running? the only time ive seen the wire melt only at the amp is when the amp is on its last leg

 

The amp has three 25 amp fuses on it and he's had that amp running for a couple years now so it might be giving up already then

 

A grounding power cable can cause melting or a wire so small for your power output. check the amp on a bench tester or swap it with another one to rule out the amp. Check all of your external wires and that they are no bare or touching bare metal.

 

I had the same problem only with other 'vendor'.You need to check it out all of your cables, wires, or better to change all these for high-quality stuff.
Its not enough to have high-tech audio system if your cables/wires are chinese...
