Question about MA Audio Hard Kore HK-898 Car Audio Amplifier
I have recently purchased an audiobahn AW1200V 12 1400 watt sub its dual voice coil with 4 ohm load. i also purchased an amp ma audio 800watt 2 channel HK798 amplifier and have had nothing but trouble with. the amps protect light keeps coming on after 20 mins. of playing. when u touch the amp it is extremely hot which i do not understand since it is supose to have a built in fan. i have been to the audio place numerous times and they seem to know about as much as i do. the amp will eventually get out of protect mode but if on for longer the fuse on the power wire will blow. i just recently changed the wiring from 8 gauge to 4 gauge and the problem is still there. the sub is wired in parelell to bring the sub down to 2 ohms. I have not a clue what the problem is and was wondering if its the amp or something to do with the wiring of it. i also noticed when i turn my radio off the subs plays loud constant bass.any idea would be helpfull . thanx
My car amp plays for 30 mins then goes into protection mode but the amp is not hot and none of my fuse r blown if some one knows y this keeps happening let me know.

Hi Saint108. You're describing it well, and i know what the problem is already. The MA audio amp, can't hold with a 2 ohm load. It's too low for that amp, that's for sure. Those are budget amps and they are not well built enough to handle low ohm setups like that. It's overheating and there's no ways around it.. Other than wiring your subs differently ! Just wire your sub directly (not in parallel) in a 4 ohm load, you will notice it will stop overheating that much. Do it quick, you'll most likely fry your amp giving it such hard work !! The HUM you're hearing could be related to it also. Try that, and keep me posted on the status. Thanks ! Cheebster.
