Check connections at speaker terminals.

Worst case.... you had the volume turned up to MAX when you fired it up and you blew out the output transistors. OR...the head unit was bad when you installed it. If you are getting ANY sound out of it, the unit is hooked up OK. Might not be any of those things; there are a myriad of possibilities.

man it was a LONG night..

I wanted this stereo hooked up because I am going to mrytle beach today after work to meet up with the wife and friends (already there)..

Anyways after I posted this issue with the speaker I went back outside to kick the head unit around.. on the way out I grabbed the instructions. Turns out I had the positive of the left right speaker attached to the negative of the back left speaker.. (i know.. I know..)

I worked on the amp and sub until midnight last night.. thiswas my first stereo... hopefully I have everything taped up good enough that she won't catch fire on the way down..

thank you for the suggestions everyone!!

We need more info, such as the model of that Pioneer. If it's an older one that has the rotary volume **** (potentiometer) then it could be dirty with oxide buildup causing the symptoms you describe. Speakers that are wired 180* out of phase don't cause static. However, you will loose low end as one speaker is sucking in while the other is pushing out.

Start by eliminating components. Try connecting one speaker at a time on different channels. Try different sources....such as CD, cassette, radio.
