hey i jus recently installed a 1000w rms sub. which sounds amazing although it looks like i have installed disco head lights to as these dim loads wen i am driving with it at reasonable volume. I have 4 gauge wiring to the amp and i know i need a new battery and alternator, however i know nothin bout a) how to change it, B) what to buy, C) i dont really have a massive budget or have an idea of where to get this stuff!


So any1 got any pearls of wisdom plz as they would be hugly appreicated
