I see your concerns on them. I figured I'd get away with it crossing to over at 4-5k since the response is to 10k. I'm open to suggestions for sure if you have a driver in mind. Ive tried running no rear fill and have never liked it. This build is definitely more of a SQL build than a true SQ build. It rocks pretty good with the stock speakers in the back yet just looking at making it better. I listen to everything as far as music goes. I just want to get on to the sub section! LOL!
Thanks for all the input and comments and Stunt you can take a peek at it on Friday or Saturday when I meet up with you.
