Posted October 25, 20159 yr I'm starting a new build with tax returns and was wondering what kind of electrical upgrades I'll be needing. Q1-4500 and a Q4-90. Subs will be (2) HDC4 12s (if I can fit a 5cu ft box in my Cavalier and have room for the batteries) or (2) HDC3 10s.Was thinking HO alt obviously, I think 270amp is the biggest I've seen for my car. 2 runs of power and ground, big 3 obviously and 3 batteries in the back. Will that be enough?
October 25, 20159 yr I like to see more alt- but if that's all that's available....But I'd say you're pretty good with your plan.
October 25, 20159 yr Author Yeah me too. I'm waiting on a quote from Singer, maybe he has a bigger one. The 270 is from DC. Mechman only has a 240.
October 26, 20159 yr You can fit a box that big. Just have to build it inside the trunk. And there will be space for batteries on the sides or behind the back seat if you face them rear firing.
