    im gonna make some kick pods using my old kickpanels in my truck, but i saw a guy on here once making them with 1/4 inch mdf for the mounting plate, and then the rest was foam filler which he resined and glassed directly on top of that then wrapped them in vinyl. is this a good idea, or stick to the regular all glassed way?

    I'm looking to build a new box for my blazer. I listen to mostly rock/metal but I do like rap. From what I've read 4 cubed and 30hz. If someone thinks differently i'm open to suggestions. My max dims are 37.5 wheel well to wheel well, 32 from the top of the rear seat to the tailgate, floor to top of seat is 15. I'm planning on putting in a false floor and I don't want to block my rear window so short is good. I'm running a hifonics brutus 1208D if that matters Thanks for any help

    Well I've almost got enough saved up for a fully loaded 18" btl. I have a 2003 extended cab s10 this will be going in. My maximum dimensions are 23.5"(h) x 18"(w) x 50"(l). Those are outer dimensions. This will be powered by a Sundown Audio Saz-3000d into 1 ohm :bigclap: . I was wondering if 6 ft^3 would be fine with that much power with 80 in^2 of port tuned to 30 hz.

    Since I'm only on my phone right i can't really use any software to design a box. If you could just give me the cut out measurments that would be great. Maybe a picture of what it might look like. Tuned to 30hz Demensions 32Lx20Wx16H If possible I want the port in the middle with a board separating the the two. So the subs each have there own chamber. All help is appreciated.

    Hi there wonder what's yr opinion about such setup: 2 x 8" by AudioPulse (Epic D2) questions: 1. go sealed or ported? 2. how big should be the box to achieve lower frequency response (~32hz)? 3. will this setup be enough efficient to shake my car or it's better to go with 2x10" ? thx

  14. I need some input from some SQ guys. It has a factory nav so options would be to swap out the factory headunit with an aftermarket and good equalizers. Or just add equalizers to the factory unit. All highs will be mounted in factory locations. Two eight inch subs will be molded where the back seats are located. The product list includes the following: two pairs Focal K2 power 100 KRS 4 inch components two Focal Utopia 21 Wx 8 inch woofers One Audison VRX 4.300 One Audison VRX 1.500 What would you consider the best way to go, money not being an issue.
