blue rem wire on amp?

[in_deaths_embrace87]

ok ive pretty much asked alot of questions before. but im running a stock system, and tapping the rear speakers with a line out converter. everything is figured out except the blue rem wire that turns on the amp. i know you can tap into the fuse accessory of the car, but i looked at the fuse panel, and its wired in with the main computer, and so help me god i aint touching it. so what i figured is, what if i ran the rem wire directly from the battery, to a lil switch inside the cabin, then continued into the amp, that way i control if it makes connection. its basicly a one way switch, one side in, one side out, making one connection with no other polarity. and since the amp is grounded and running two [30] fuses, and the main positive red wire for the amp is fused as well, i dont see how it could cause any harm as long as i remember to shut it off when im done using it. would this work? considering i think a car battery only puts out around 12v of charge, same as any head unit or accessory wire.

Why don't you connect it to the main power of the head unit at the back of the radio.....this avoids going through the firewall...and the amp will come on when the car is on and vice versa....or see if there is a ant. wire coming from the head unit....connect to it..
