do you have a fuse on the power wire to the battery terminal, if so that fuse may be blown

what amp are you using and what subs do you have. are the subs impedance wired lower than what the amp is stable at?

cheap magnum kit from circuit city it worked fine just my brother was re aranging the wires and he "says" it sparked when he plugged the positive cable in and ever since then it stopped working. he also managed to rip the remote wire out also during the aranging i hooked that back up and it still doesnt work. how can you test an amp to see if its dead?

also i get power through the cables, but the remote wire only sees .02v? isnt this supposed to be 12v as well? should i try plugging it in somewhere else besides the 12v remote line?

i dont know too much about the remote wire, try using the amp on a reg power source not using the remote see if it works, seems like its fried, whats the max power output on it?

Two wires would have sparked, either the POWER or REMOTE.
->If it was the power, you probably popped the fuse under the hood, have you checked that one? Here's a quick test, take the power wire for the amp and very quickly brush it by some bare metal (or your ground if it's not plugged into the amp), if it sparks then you know that isn't blown.
->If it was the remote, you may be in more trouble since if you blew that circuit in the deck you'll have to rewire it so that the remote wire takes it's power from the accessory circuit instead. ---- Plug your amp in, but leave the remote wire unplugged, take a small wire and attach it to the (+) and (remote) screws on the amp, if the amp turns on, then you know you're not getting voltage from the remote circuit.

Make sure that everything is plugged in right, I've seen people switch the (+) and (remote) wires by mistake which causes problems like blowing fuses or shutting off at mid to high volumes.

But it sounds like your remote wire is fudged.

yes i would say something inside the amp blew or cooked....

once you get new stuff, take that amp aprt & look inside for an inline audio fuse or fuseable link type connection inside the amp & it may be fixable from there

otherwise if it has warranty, take it back, otherwise your brother owes you an amp....

did you look inside the fuses (they are usually see through) and you can see if their blown, I have had a blown fuse that shows power in the past , it could have a strip of metal stuck to it and show volts. You said you checked the fuse on the amp right? Check the manual and see if maybe there is some kind of internal fuse in the amp.
