Inspect the insulation on the wires, make sure it is not touching any metal or points where it could possibly short circuit.I had my first amp installed at a shop, and while later upgrading the wiring, i found several points upon the wire leads that had bare wire exposed because the installer did not properly route the wiring and had scraped off insulation by forcing it through sharp edges, etc. also check the ground point and make sure that it is properly grounded to the vehicles chassis, and is not touching any painted aread, just bare metal. (most likely you are going to have to rip apart your vehicle to do this (which is why the installer should do it - there really is no substitue) also, check the speaker connections and speaker wire. again, check the insulation. make sure that the wires are connectes securely to the sub, and that they are not short circuiting themselves. i had a similar problem, i ended up shorting out the amplifier by the speaker wire connections (not secure).again, i would go back to the installers and talk to them about it. they did what exactly i figure any lousy installer would do, blame it on the amp and just fork over for a new one. i think it is a substitute for a much simpler problem. go back and suggest some of the possibilities that i mentioned.</blockquote>
