right i got a 2400 watt juice amp powerin 2 1200 watt kenwood subs, i have got a cheap amp wiring kit from an old car i had and i know they wont be that good, but i noticed my lights dim when my bass drops, i did think about gettin a power cap, but ive had too many people saying naa its a waste of money, so my question is, is it worth forking out 35 knicker for some uprated wires and will it save my battery a bit better?
cheers people
