Hey guys.
Recently I decided to get into the audio game and started building up a system in my truck (94 nissan king cab).I picked up some new speakers, New head unit (pioneer 4000) and a new amp (Pioneer 3300t).I did some research and had my uncle who is an electrician help me with installing everything. Everything was working fine but on the way home it just stopped working. The only sound that comes through the speakers is very faint music for about a second then it cuts out and back in again. I have checked all of my connections countless times and I can't figure out what the problem is. Anyone have any ideas? The power light isn't flickering so I don't think it is my power cable or ground. All help is greatly appreciated because I want to get subs but I am waiting to get this resolved first.

 

Just rechecked everything again and here is what I've discovered. With or without my rca cable plugged in, whenever i hook up a speaker (i tried 4 different ones) this causes the amp to cut out.When it cuts out the power light goes off and the speaker sinks down and makes a crack like sound then power light comes on and speaker goes back to normal.

 

When I hook the speaker up to the left output,the power light doesnt flash and the speaker doesn't "pop" but i still get very low audio that cuts out. With the speaker hooked up bridged i get speaker pop but no power light flicker. When I hook up my rca cable, the right one alone makes nothing happen (no audio either) and the left one alone gives me the low audio that cuts out. And the both of them together give the same result as just the left.

 

Check all your speakers with a multimeter, your uncle can help you with that. If they check out then swap in a known good amp to test the system.
