    General Car Audio Discussion
    Hello Friends, Been a while since I posted here. I've been busy but I decided to pick up my old hobby again. I was hooked up with some excellent stuff. Got myself an Audison Bit One DSP for just $100, and some other stuff. Rockford T1500bcp for just $200. Now, I've got some kind of Android...
  2. Convert an Headphone Output to Line Level Output

    Technical & Advanced Car Audio Discussion
    Hi, Does anyone knows if it is possible to convert an "Headphone Output" into a "Line level" output? (I mean, to bypass the internal amp of a device to deliver a non amplified signal). The thing here is that I want to connect my smartphone (Samsung Note 3) to my Zapco ASP-q1 (car in-dash...
  3. Need help with Alpine Pdx f4 and alpine spR 65 speakers

    Technical & Advanced Car Audio Discussion
    Pdx f 4 amp powering type r components up front and coax in the back. I also have the alpine 149bt head unit. I have no subs, so would I leave the amp crossover on full range?

  6. RCAs and Crossovers

    General Car Audio Discussion
    I'm connecting three amps to my deck, but my issue is that I have three RCA cables (one from each amp) but my HU only has one set of inputs. I've heard of something called a crossover box with multiple inputs and one output. I need one with three in and one out. If anyone can point me in the...
  7. IB output: (2)12 IB vs (1) 12 sealed

    Technical & Advanced Car Audio Discussion
    After seeing install log with bmw 5 series where owner utilizes skipass to do (2) 10" IB facing rear, I am wondering if I would be happier with (2) 12" IB, possibly even facing each other vs single sealed 12" that I have now riding with me on the back seat (not laughing). So, how would having...
