[QUOTE="ThxOne, post: 8737390, member: 675210"] I am in the process of getting another 4 channel amp. All day yesterday the amp was messing up. Right channel cut off a few times then came back. Left channel almost all night plays at like half to 3/4 volume of the right channel. It's annoying. Maybe it's a class A/B amp issue... maybe they just cant handle constant use. It's supposed to be 100w x 4 rms and I am pretty sure I am under that because I used my O-scope and multimeter with a sine wave to set and make sure the gains were not clipping. 18v @ 4ohms is right at where front and rear gains are set. The amp gets plenty of air as it sits where the bottom back seat cushion used to be. Not that it ever really gets warm. This is amp #2 from US Acoustics. The first one really went south and one of the RCA inputs came off. But that amp took out my single DIN Kenwood eXcelon head unit. It's sad because when it plays normal it sounds great and is really loud. [/QUOTE]
