Ok, I've got a very small convertible, and i had my system installed a while back at tweeter and they measured the trunk for my sub's and box and said that there wouldnt be enough airspace for the subs so they built a sealed enclosure and put them in the backseat firing up. When i used to have my 1000/1 running my subs it seemed alot louder than lately when im running my subs with my 2 500/1's, does anyone know why that is? it could be my alternator getting weak? and also does my car being a convertible effect SPL a whole lot? im guessing it would. Can anyone recommend anything else so i can possibly get back to as loud as it was?
thanks in advance
Brad
