Connect turn on wire some where else?

Question

my head unit is fried and i don't have enough money to buy a new one so now i cant turn my amp on because i don't know where to connect the remote wire that does not involve connecting it to the head unit really need help on this one plzzz!

Answer 1

Connect it to a switched 12 v source on the fuse panel. When the key is on , the amps will turn on

Answer 2

You can connect the remote wire from the amp to an accessory wire on your car.

If your head unit is an aftermarket head unit (i.e. Alpine, Kenwood, Sony, Pioneer etc.) its probably a red wire going to the radio.

Answer 3

If your not going to use a head unit then the simplest way is to install the turn on wire to a SWITCHED 12vdc power source at the fusebox and the amp.

Noticed I said Switched; this way the amp will turn off when your car is off. Take voltage readings at a fuse on the fuse box and find one that drops to zero when you turn the car off and 12vdc when the car is on.

You CAN use an UnSwitched 12vdc power, but you have to make darned sure to turn that switch OFF when your out of the car so the battery doesn't drain down from the amp when parked.

For safety, install a small (2 amp) switch on this lead. You can get an in-line fuse holder from Radio Shack.

Answer 4

why do you need to power your amp if you have no radio ?
