I just got an active crossover and I was wondering what size wire I should use for my +12 power wire. I currently have an 8awg run from the battery to my PA amp [model in signature] which is rated at "740" wrms bridged at 4 ohms. I plan to add my alpine 3525 (Ampguts says: 2 x 60W @ 4 ohms, 2 x 80W @ 2 ohms, 160x1 @ 4 ohms bridged) and the crossover [which is in my sig]. Will I need to step it up to a 4awg run?
