20 Most Recent MA Audio HK802SX Car Audio Amplifier Questions & Answers

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.

If you can identify the numberic cord on it we can find you one online

did it work well before?is it new? try moving the rca's and se if you hear any thing?

So it sounds like your need to check your ground wire. And make sure it is connected directly into your car's chassis

this amp does not use any fuses

You think what is blown, the amp, What is it doing?

you need the speciall conector becous its a little problem your conections

Ok This is a two channel High Current amp. It is stable to one ohm. If the Subs are single voice coil at two ohms the they have to be wired in Parallel that means (Red +) (Black -) are connected to the + and - of another sub and then the (RED +) (Black -) from both go to one output channel of the amp. You pair the other two in the same fashion on the other output channel. If you are getting no output (sound) at all first check if the amplifier is going into protect. (Usually indicated by a red led on the unit. If it is connect only one Sub to each output and see if the protect LED goes out. If it does then you should have sound at the subs. If not check that you have the sub output enabled on the HU some head units do not come with the sub output enabled on the HU. If every thig is enabled, with only one sub connected to each output and the protect LED is not on then your amp is probably blown and needs repair. Nice thing is that MA has a great warrenty policy. Check and make sure the protect LED is off. If it is on you probably have the SUBS wired wrong

Afraid you may have blown an amplifier. If you have a AC voltmeter, audio generator and schematic, you can feed audio signal into unit and track the signal on both channels during amplification stages.and locate the spot where the amplification stops or one channel deviates from the other. And there is your culprit.

There is little chance that you can do anything about it. The exact voice coil would have to be identified, the old ones taken out, and replacing them is technically difficult/impossible without the proper tools and experience.

Have you installed Kicker capacitors? With the extra power you have you will need them to help with the load.
