    Technical & Advanced Car Audio Discussion
    So.. I won’t go into too much detail, but this would be a second build of the same car. (This would be by 5th or 6th total full build) This one is a 94’ Chrysler 2-door coupe. Small. Ass. Car. LOL It’s a competition build, but not for competitive purposes- but for entertainment purposes. You...
  2. old (ancient) Pioneer TS-WX206A

    General Car Audio Discussion
    I still have one of these, it still works, but I want to mess with it:D so I took it apart and noticed a few things: - there is no reflection damping inside (thought that was needed with a bandpass?) - the woofer is a DVC 8" 2x2 Ohm (and I lost the pic showing the markings...:mad:) I've been...
  3. 4th Order Bandpass Enclosure Box Sizes

    Technical & Advanced Car Audio Discussion
    Hi all, newbie to the forum here. I'm working on a couple of small 4th order bandpass enclosures for a couple of 12" subs for my car at the moment (size is quite a constraint) and I'm curious about how the box sizes affect the frequency response. I used a 4th order bandpass enclosure...

  6. PPI BK340.4 and PC3.65C Review

    Member Reviews & Product Comparisons
    All, Long time reader, first time poster. First of all, allow me to thank everyone for providing an outstanding forum for learning and research. I bought my latest project, a 2013 Scion FR-S, and as usual, the factory audio was sorely lacking. I was impressed with the factory use of 3 way...
  7. AB 3/4-channel, w/ subsonic, .>320w bridged: SQ amp options?

    System Design: Help Me Choose Equipment For My Car
    Been looking for an SQ oriented 3 or 4 channel amplifier for a reasonably small system in my station wagon. I'm looking for a bridged 320 watts or more to power a subwoofer. I also require a subsonic filter or comparable bandpass capability for running ported. I'd like for feed not much more...
  8. 4th Order Bandpass with Dayton UM12-22

    Technical & Advanced Car Audio Discussion
    Long story short is that I'm building a 4th order bandpass enclosure for my car. My plan is to have the enclosure in the trunk and port the box directly into the cab through the rear deck where the 6x9's sit. The theory to my madness is to reduce trunk rattle and overcome certain issues with...
  9. Calculate combined spl (multiple bandpass)

    Technical & Advanced Car Audio Discussion
    I was wondering if there would be a way to calculate spl of two or three different sound sources. What I'm calculating is spl from small bandpass boxes. I have to use bandpass because I need to vent the sound into the cabin of the car. I'm going to be using two or maybe three 4th order boxes to...
