Question about Phase Linear UPA424CS Car Audio Amplifier
I recently purchased a Phase Linear UPA424 amp about 2 days ago..I was working on my car, installing the spekers and what not and when i went to hook up the amp to the speakers i had nothing. It worked the day before just fine. I figured it might be the battery but still nothing. The unit is getting power and the green led has light, but no out put signal is comming from the amp.
I hooked one of these up in my cherokee a few weeks ago and I wound up having it in for a coulpe days befor I got it working it would work briefly and stop I changed power wires twice before getting it going by using both sides of some 14 ga speaker wire for the + and ground
