well, I wasnt for sure if u had allready got this settled and setup or not. I have the 2007 Ford Ranger regular cab and I have two 10s and they def. do not kill the mids and highs. I dont know how all of ya'll r deciding on what ya'll want but I'll go ahead and say now that more subs or bigger subs doesnt always mean louder or more pound. u can get a nice sound from two 12s and they can sound just the same as two 10s, it all depends on the power as well as the box. I would suggest putting two tens back there in a box that just sits in the middle and points ur subs toward u. what u might want to try is not going over 200 watts RMS per sub. that is the rating that u need to go by when looking at any and all car audio, if ur sony is 330 wats RMS and ur amp is pushing 500 watts RMS, ur sub is probably distorting and when ur sub distorts its in the process of busting. if u would like me to I can post a couple of links to a few pics of systems that r just meant for SQ(sound quality), and if u want something to get some pressure going in the cab I'll post some links to pics of setups for SPL(sound pressure level). I'll even post a link to a vid of my system, it's for SPL but it still sounds really good and I havent even added my tweeters and crossovers yet. sorry that was so long.
