i met a few people at SBN in the SQ room with parts express mids and stuff. its in the build and how you angle them and cross them over. oh and how its eq'd as well. i saw a lot of hertz stuff, but those ARE pricey. stick with what you know sounds good to you. polk, infinity, JBL. those dont cost an arm and a leg. what sizes and how many speakers fit up front in your car?
