F/S MA Audio HK4000D

Item(s) for Sale: MA Audio HK4000D

Item(s) Description/Condition:

Up for sale is a good monoblock amp. It's used but still 100% functional. I purchased this amp from this site over 2 years ago. I used it to power an 18" Fi BTL for 2 months. My car alt was upgraded prior to the system being installed, so this amp has never seen below 14v. It was wired at 4 ohms. This amp never ran warm. It does have it's signs of wear, and the pics below show this. It's never been modded or repaired, 100% functional. I'm only selling it because I've moved onto a totally different system. This amp will do rated power. It's a really good budget amp that will put out some serious power. This is the perfect amp for someone looking to get lots of power while on a budget. I've seen others run this amp as high as 18v. It's a really good amp, I just don't have use for it at the moment. If anyone has any questions or comments, please feel free.

They always took the higher voltage, it was the lower impedence which they couldn't take which is why you cut a resistor on the board. I wrote something up on it a few years back...its probably lingering around here somewhere.

Surprised no one has picked this thing up. GLWS!

So far just the typical guys claiming "cash in hand" but when it comes down to completing a transaction, they "all of a sudden" have important expenses they need to take care of.
