    Where did my midbass go?

    In order to get my 2 way active setup in phase was to change the polarities on the tweeters. Beings you have a 3 way, there’s no telling which drivers are out of phase.

    Where did my midbass go?

    When you do a major dash install for stage and image, your ultimate goal is to have the entire sound up and out on your dash. Your mid bass is most likely where you left it, just blended with the dash. Once I got dialed in with time alignment, my doors practically disappeared (way they should be). my guess is your doors are out of phase with your dash drivers (if you have them wired exact negative and positive). First thing I would try is locating an audio test disc. If I can remember correctly, you can order one from USACI. Change the polarities on the midbass drivers to phase them up with the dash. Hope this helps !!!
  6. I would contact the manufacturer of the board for a schematic diagram or a recommended repair shop.

    Tunning Recommendations

    I’m no enclosure designer, but most setups I’ve seen with a simple pair of 12s is sub’s back, port back with a 36ish htz tune.

    Randal's 2007 Chevy Avalanche

    Personally, I can not tell the difference between 2 way passive and 2 way active. Going active made me use 2 amplifiers with no major difference with stage and image. Shows how good my speakers are installed I guess. Think i’m Going back to passive and get my sub back on one of my 2150s for now. 2150s have the best left and right separation Qualities so I should be good there. Hopefully, I can get this done this weekend. As for the Helix, love the EQ capabilities !!! 32 bands on the left and 32 on the right !!! And time alignment is WAY easier to tune than on the Kenwood. Not spending the money on a sub amplifier will help me get closer to the new Kenwood head unit !!!

    Subwoofer reccomendation

    I understand brother, my family is the only reason why I’m on call 24-7 doing heavy recovery. However, I do find time for my Avalanche. Not much, but it keeps me happy. Get it all playing and post a vid !!!

    Subwoofer reccomendation

    Herman Smith (MECA SQ Competitor) has one similar. His sub enclosure and amp rack is a center console stretched from dash to rear window with 4 bucket seats. I know it can be done. also, posting vehicle pics would help us help you with ideas and suggestions. Just trying to help brother ...

    Subwoofer reccomendation

    Find a pair of buckets in the junk yard and replace the rear bench and build a center console for the rear of the vehicle.

    Who's got enclosed Evil mids?

    Good luck with kicks, I’ve never had any with them ... even when I vented through the body panel.

    Who's got enclosed Evil mids?

    Deaden the shit out of your doors, install rear wave canceling material behind the drivers, make awesome baffles, mlv between the panel and door, throw some bad ass class a/b ssa power to them, and rock them bitches !!!

    Who's got enclosed Evil mids?

    As in bookshelf speakers ??
  23. I’d much rather blow a 100 amp fuse than to burn up an amplifier with an over sized fuse. Honestly, depending on good wiring practices, you should be fine with a 100 amp main line fuse.

    Shallow mount subs? Who's using them.

    I’m trying to locate my pics of Dylan’s 91 Ford F-150 single cab install.
  25. If your amplifier has 120 amps of fusing, your max fuse in the Audio run in the vehicle should be no more than 120 amps. If you go over max fuse rating, the fuse will not do it’s job. Just Saying
