Willing to trade my rf punch 800a2 for an a4, bought amp new and has never been down or repaired, tamper stickers are still unbroken, amp is over kill for my mids and mid bass so need a four channel. pics are available for those interested.
I'm currently using a 400x us amps for my subs and I bought another which I plan to install next week, my question is do I need to run another 0 guage from the battery to feed the amp or do I just feed it of existing wiring and get a 500 amp anl?
