Everything is wired negative to negative, positive to positive, i will try the front speakers this morning(wont take me 15 min). I think its a combination of terrible speakers(if i turn the bass up past zero on the factory deck they sound like ****) and no separate control for the sub.
Im going to look at aftermarket decks today.
What difference would a 2.5v volt pre amp or 4 volt make in this sub/amp? Cleaner signal is what the word around the web is, but is there actually a difference in volume at all? since the amp is starting with more voltage i would imagine so. I dont think its worth the extra 150-200 dollars...
