Question about Jensen XA4150 Car Audio Amplifier
I have had this amp for 5 years...its been flawless. However recently I lost one channel. I verified it wasnt a speaker by switching speakers wires on the amp to the good channel. I checked the 2 fuses on the amp...they are good. Do you have a wiring diagram before I tear into this..Im guessing one of the power amps ( internally) has had it. I am electronics savvy and have repaired things like before. I just like some insight from someone else, if youve already attempted this repair and if the parts are available.
Also I paid $300 for the amp and the 10 inch dual sub box...should I just call it done and get another amp at this point. Its been in my car and running for 225,000 miles...and its had A LOT of heat cycles.
Have you tried switching the signal cables?
Try moving all of the controls and switches. A dirty contact can cause similar problems.
If these don't help, you probably have a broken connection in the amp. Generally, when semiconductors fail, you have excessive current draw and the amp goes into protection or blows the fuse.
