that was why i finally just said the heck w/ it and bought a new harness.. haha
i'm going to try to pull the amp out this weekend to check connections and if anything is loose internally. what should i look for specifically?
It is no problem at all, that is what the Bazooka Forum is for, helping people out.
I would trace that pin (the ground) and see what it looks like on the other side of the amplifier. If there is a break, it will be obvious. And while you have it open, you can always look for black spots (indication of burning) or other loose components. The amplifier itself is a pretty simple, but extremely effective IC (intergrated circuit) so there are far fewer components. Post back with what you discover. Our forum wizard, rainmanspl, may also have a few thoughts on the matter. He is a car audio professional and is very good with responding to posts and trouble shooting. And if worse comes to worse, $24.95 is an investment in that EL Tube!
