i’m going to call up JL Audio and talk to them, like i did for this enclosure design. im going to be using a sealed enclosure design this time. i sometimes use the trunk to put things in it. its kinda nice to have some room. my setup is Eclipse 8455 HU, Rockford Fosgate 3SIXTY.2 sound processor, MB Quart RAA4200 4ch speaker amp, MB Quart QSC 6.5’s and tweeters, Diamond Audio DS1200 sub amp, JL Audio 12" W7 sub. The car is SQ setup and I’m not looking for a show lvl install, i dont compete anymore.
