I will second the opinion that the Sony system with the sub sounds awesome. My last truck had two 10" subs in it and this system is just as good. I don't need a ton of bass but I want to know it is back there.
I have one question for you Pig9r - how did you trim that weathertech mat around the sub? I looks like in your picture that the back of the mat is connected behind the sub...is it? If it is then what did you do, remove the sub bracket and lay the mat down, then re-install the bracket?
I didn't do it that way - but am now thinking that I should have. The piece of mine that is between the sub and door is kinda loose - but it is alright I guess.
