Question
i have a 4000w lanzar amp with two 2000w plye subwoofers
how do i install it? i have no clue what i need! What wires or anything like that!


Answer
First your amp is too big for the woofers,(or the woofers are too small for the amp), you should have at least a 50% safety margin so 4000w amp = 2 x 3000w max speakers. mind you, are you sure about those number FOUR THOUSAND WATTS? That's as much as out local radio staion pumps out! I only have 640 watts in two amps in my show car.

Wiring, VERY heavy cable from amp to a separate a 100 amp hour battery (preferably a spiral one)fed by a split charge relay of 75amp or better connected to the car's battery plus terminal and then via the realy to the plus on the slave.
switched by the thin signal wire from the alternator. In-line fuse NEXT to the battery. Earth cable to ground as near the amp as possible, same size as power lead. signal wire (between power and earth usually) to signal output on radio.
