Most power for under $1k

If you were building a budget system and had just under $1k for the sub amp, what would you get and why?
Looking for an efficient powerful amp. Running on stock 140a alt, with 1 batt under the hood and 2-3 in the trunk.
You won't support much power with only a 140amp alt. and a couple batts Just sayin.... Before i beefed up my electrical more, I had a 140 amp ad244 in my truck with 3 deka group 31 batts and it wouldn't support my powerbass 5k at 1 ohm. As for a lot of power under $1k. There are tons of options.

2 powerbass 5ks strapped for 10000rms used would be under $1k

There are some amps for sale local to me that I could play the middle man for you.

Sundown saz4500 like new $900

Powerbass xa4000d $475

Digital Designs Z1a $700

Digital Designs M3a $550

I know I'm not going to get a ton of power... which is why I'm looking for efficiency. I can't do an alt because I wouldn't qualify for certain classes the local competition has. My buddy competes in a higher class (doesn't have a limit on alts/batts) and he's running 3 300a alts...I would have to put too much money in to compete against a teammate lol, he's winning most the time. I'm looking for something that will run on mostly stock electrical/give good output.

I gotcha. I'll keep my eyes open and let you know if I see anything

 
Strap a pair of MMATs 3500s, efficient as hell and would do around 6k no problem

Also my M3a is pretty efficient, and if you look around you can find the older silver ones around $500 and the black ones for around $550 usually.. Rated for 2200w at 11.8v.. Here's TaylorFade's clamp, rising to 0.9 ohm:

DD M3a

-13v - 3,657w @ 11.2v

-15.5v - 4,088w @ 13v
