How do you install an amplifier into a car?

Answer 1

Depending on the watts the amp is will determin the size of the wire you will be using. You have 3 basic cables the power wire, remote wire (16 or 18 gage) and the rca's. First you run the power wire from the battery to the amp ( make sure you install a fuse holder ) on some cars it's easy run the wire, some firewalls have pre made holes you could use for the wire. If the car has no hole by using a unitbit you could make your own hole the size you need it to be. If you have a factory radio you will also need a high to low converter so you will be able to convert your factory radios speaker wires in to low signals for the rca's you will be using. If you have a after market radio if should have rca's out puts already. Next is your remoter wire, factory radios you could use the ignition wire for the amp, after market radios use the amp turn on lead (blue/white on most). After you run all 3 wires to your amp read where the wire should be conecter to.12+ battery wire , turn on lead is your remote wire rca's to rca's input . Last wire's you need is the ground wire (same gage as the power wire) find a peice of steel from the car, under the seats scrape of any paint and ground it . The only thing left is pluging in your speakers.. enjoy ....
