Probably has to be at 4 ohms, but any ohmage is OK. Money is not an issue, but want to keep the stock alternator... so 1000@ at 50-60% at 1 ohm is not going to work. 1000W at 4 ohm at 88% should be fine.
I have a Kicker 1500.1 and JL 1000/1 laying around, but neither of those are too terribly efficient. Thinking about buying a T1500-1bdcp if nobody has any better options.
Thanks in advance.
