wtb/wttf Amp for power @ 4 ohms, around 2-3K rms @ 12.8V

[audio_phill 10+ year member]

Title says it all, doesnt have to be new, but not interested in modded or repaired amps, I have 1774 @ 4 atm but looking for class D because this class a/b is just too inefficient for my current electrical. 222 amps atm to make 1774... class d will allow me make around 3K @ 292 amps which would be fine and give me more on tap...

Have stuff to trade, subs amps, comps, coaxials etc for anyone looking to do some swapping, or if we can agree on a price we can do something with cash.

2-3K @ 4ohm... d@mn you are about to PAY for that

Lanzar OPTI6000D is probably your best bet.

can't think of any other amp that does awesome power in that high of ohm load... no experience with 'em but you can ask the man himself... I put in the specs for it...

Say you're running a pair of D4 subs, why not wire down to 1 ohm?

That's what I was thinking

Right but there are more amps that could do that power at the lower ohm load just choose one that's efficient

sounds like a AB hybrid could be in his future!!! I know what he's saying though, I wired up....

It would probably be cheaper to get a HO alt and a 2-3k amp at 1 ohm than a 2-3k amp at 4 ohms

not if he gets the one I mentioned ^^^ there 4000w @ 4ohm

Power at low ohms is not a problem, I have plenty of stuff laying around that makes power at 1. I dont like wiring subs in parallel, I like full motor force to keep as much cone control as I can get being an sq/sql guy. Why have abl of 15 when you can have a bl of 23 lol.

The opti 6K wouldnt make 4K @ 4 on 12.8V, but would probably make enough power. I really only need 2K, but dynamic headroom is always a plus. I'd rather feed a 2K sub 3K clean than 2500 clipped anyday.

Working on an 18" Exo setup, and with its sql potential, I really want to maximize its potential.

Not too much, just too much for the power I'[m getting, but thats the price for a/b sq lol.

At 1 ohm, damping factor and efficiency are cut dramatically and THD climbs. best option for me with this goal is sufficient 4ohm power. Class d @ 4 ohms can be 85% efficient but 75% would suffice for 3K of output without me having to alter my current electrical setup.

What about the us amp usa-2000x...

Don't those do power at 4 ohm?

Just throwing out ideas
