  1. Mix impedances in the same amplifier

    General Car Audio Discussion
    It is perhaps a silly question, but I have always had this doubt: When a multichannel amplifier is stable, say, at 2 ohms, and for example, the specifications are these: 6 x 75W @ 4 ohms 4 x 110W + 2 x 150W @ 2 ohms Is it possible to connect 4 channels to 4 ohms, and 2 to 2 ohms? Or all...
  2. Help needed in hooking up sub and amp

    General Car Audio Discussion
    Hey guys. I'm completely new to subwoofers, and i don't really know how to hook up what i have bought. I have a Pioneer TS-W307D2 sub with an excalibur x300.4 amp. Now i have already been told that this is far from an optimal combination, but if it works i'm happy. I have done some research...
  3. How will increased impedance affect output in the real world?

    Technical & Advanced Car Audio Discussion
    Forgive me if this is an overly simple question. I've done some looking around, and I can't really find what I'm looking for. I've read a couple of articles on Ohm's Law and I'm either not taking enough time to understand them, or they were rather poorly written. I've searched on here, but...
  4. Speaker selection for RIPS (JL 300/4v2) amp

    System Design: Help Me Choose Equipment For My Car
    Hi, I have acquired a 300/4v2 amp after purchasing some Polk MM6501 component speakers. I intend to use the amp in a stereo/bridged configuration to drive a sub as well. Unfortunately I didn't know about how RIPS works before I got this gear. According to the manual, for max power for the...
  5. Focal TA241 Tweeter Impedance

    Technical & Advanced Car Audio Discussion
    Hi guys - first time posting on this forum, but I have been reading here for a while! I recently installed the Focal polyglass 165vb component set in my car. I'm very happy with the woofers, but the tweeters are often too bright (probably because of location, but I don't want to cut or glue...
