I need some help with my system. There are a few dudes around my way with chevy caprices and they all claim that their systems are the s***. I too have a caprice and I would like to compete with them @ this car audio and show called sound clash. Every body with a system will be there showing off their stuff.All I need is a really good box for my subs and some realy good componets. The competion is broken down in three parts from what I've heard 1.DB drag. I belive this is the part that uses SPL meters. I have never burped subs b4 so if ayone has any tips let me know. 2, SQ. 3. street bass. The guys I want to compete against have either multiple kicker setups or multiple JL audio subs and maybe mephis mojo's. Two cars have 4 L7 12's and one car has 6 cvr 12's and another car has 4 cvx 12's. Also there are two dudes with JL audio setup. One caprice has 6 jl w7 10's and the other has 3 jl w7 13's. All of these cars are different as to what subs each person chose but all of them chose beyma mids and highs. Some of these cars have six or eight 6.5 's and four 8 inch drivers as well as four 10's in each door or the rear deck with 10 bullet tweeters spread out in the car. Is all that really nessasary? I have never used beyma componets so is beyma a good brand to use? I have two DD3515's at the end of the month I am getting a third one. Along with those DD's i ave two pair of the morel tempo 6's.. I have been looking @ Partsexpress.com I was wondering if I could use their raw drivers in my car. I am looking at a few mid bass,mid range and tweeters. I want to build a 3way componet set with these drivers. Also I want to use a pair of the mid range and tweeters to make a center channel. If anyone has used these drivers in their vehicles let me know. Also shoul I go four 15's or stick with three? Any help or comments that can be of help is greatly appreciated. Thanks!
