MA Audio HK802SX 4400w Amp

I bought this amp like 2months ago and had problems with it, sent it back to ma audio for replacement, when i got it back it worked fine for 2 weeks then i decided to plug the remote bass control they sent with it up and as soon as i did the bass stopped all together. I then unhooked the remote and still nothing, the subs hit as u are plugging it in, but once you got it thats the only time... wth any ideas? really dont want to have to pay the shipping back and wait another 2mths....

Re: MA Audio HK802SX 4400w Amp

Hi, sounds like u have a problem with the remotebass connection socket. the socket has little pins inside, check to see if they arent touching each other. also try not using the bass control, then try one sub at a time. u may find that one of the subs or sub spk wires cub be faulty. cheers.

Yes it depend on how much damage is on the system. What you need to do is to identify the transistor model and look for replacement parts.

All fuses are going to be external (adjacent to the power terminal block).

If it's new, return it. It's under warranty. Any tampering will void the warranty.

Let me know if you have any other questions.

MA Audio HK4000D please help me ?

Turn the system off and disconnect the speakers. Turn the system on. If the amp still goes into protection mode with no speakers connected, then most likely the output transistors are bad. If the protection light is off, hook up one sub at a time until you find the one that is causing the problem
