Question about MTX Thunder 8302 Car Audio Amplifier
I have a 75x2 MTX amp bridged to mono driving a pair of 10 in Audiobahn subs, the amp has worked fine for 4-5 years now, but in the past week or so it has been giving me a huge headache. I have a 5 speed truck and when I am (for example) sitting in traffic it plays fine, once I pull out and hit about 45mph, it quits...I replaced the wiring and I replaced the stereo with another one I have and no help. So I took an Alpine amp out of my other truck and it plays perfect in place of the MTX. The amp isn't losing power, I see the light on even when the amp quits playing. Could this be a problem with the voltage increasing from the alternator during higher rpm? Could the higher voltage be causing my problem to re-occur? What could my amp trouble be? Maybe a bad/shorted output? Please help!
Yes, the overvoltage...compounded by maybe an alternator that is also not operating within limits (Does your headlights or horn get brighter / louder?). look inside the amp for any adjustable device for OVER VOLTAGE THRESHOLD or similar and turn it slightly clockwise
