Power acoustik amp problems
I have a power acoustik lt-980 2. I wired it in my car hooked up the subs and nothing. I got them used and the guy showed me it was good. I suspected my RCA jacks, but checked them and they were good and also tried a good head unit that worked with an amp. The amp goes into protection mode as soon as I touch the RCA wires to the amp, and when I disconnect the RCA wire the light goes out. I have no idea what is up and really need help. Thanks so much.

8 volts may not be enough to allow the amp to turn on. You need to determine why you only have 8v.

It could be anything connected to the B+ or ground terminals. I'm assuming that the battery or power supply you're using is producing at least 12v.

Ill check the battery tonight. And B+ is just power right? And does it matter that the blue light by the streaker out put comes on?

B+ refers to the positive supply connection from the power source.
