Any other forum might agree with you budahbuddy803, but here at caraudio.com..... LOL, I don't think anyone needs "all that bass", but I've already got the subs and amp sitting here (not to mention I've yet to hear two 13w7's on two 1000/1's, so why not?). They were for another build I was planning until I got the IS300. Thanks to all for the thoughts on this. I'm tossing a few things around, still havn't had a chance to sit on the phone with JL yet, but even then they're pretty much going to tell me the spec's of a STANDARD ported and sealed configuration..
