I have a ma audio hk-802sx and a ma audio hk-4000d forsale.Both are modded to take more voltage witch means more output power and you can use lower ohm subs than the companys specs.The hk-802sx i need $350 shipped and the hk-4000 $400 shipped.All specs are curved a bit because of the mods and the numbers are higher and with more votage they will also get higher.The hk-4000d can do a 1 ohm or somewhat lower.Some specs:

what kind of electrical would be required to run the 802sx daily? at its .5 stereo load. current is stock alt, and 3-4 extra GOOD batteries. would it support it?

Lol,sorry.You can eather use 4 or 0 gage wire is okay.If you have 2 batterys and a cap it would be fine for it with the stock alt..I know this setup will work and made full use out of it.Anything you add more will be a plus because of the mod.Make sure you add a relay in your remote wire to get a beter flow to the remote input.These amps need a 12 volt stable and most of these amps have problems if they don't get it.I have a diagram if you want to try it.You sound like you have a great power supply and maybe even more than it has ever seen.What sub are you using?Other than that your good to go and i noticed the 4000 needed a bit more power than the 802sx.

my remote wire is on a switch in line with my accessory turn on from my head unit. the subs are what im putting in a daily wall, 8 kenwood 12s. ive been looking into two slightly smaller amps or one like this to push it all. all single 4 ohm coils.
