Well i just got the call from my dealer saying that my new 08 SCREW is going to be here any day now( wasn't suppose to be here till late Oct.) So i have to get my whole system planed like now. I tried looking already but i couldn't find any thing so im just asking, what is the maximum mounting depth for a SCREW with out lifting the seat. I think its some were around 6" but im not sure. Also does any one have any suggestions on some great sounding speakers and good monitors for the back of my head rests?

 

anything over 5.75" is going to be pushing it without a seat lift. my sub is around 5.25" depth and it barely fit. id aim for somethin below 5.5" of depth if i were you.

 

A 8" Kicker L7 is going to more powerfull than the stock sub right?(i know this question is obviouse but im just making sure)

 

absolutely it is more powerful. but a sub only sounds as good as the enclosure it is in, so make sure you build a solid box with the right specs and it should sound great.
