    B5 S4 Car Audio

    Guest-only advertisement. Register or Log In now!
    I'm pretty knowledgeable when it comes to cars, computers and electronics, but clueless when it comes to car audio. I wasn't a fan of the stock system, and one of the 5-1/4"ers were broken anyways. So I did a little research and learned that if I upgraded to 2ohm speakers that they'd work fine with the factory amp. So I replaced all 6 speakers with Infinity Kappa speakers and it sounds great. But naturally, I think the speakers could use some more power; more than what the factory amp is giving them. This is where I'm stumped.

    What kind of amp should I go with? (Specs of speakers below)

    Speaker/RMS-Peak

    42.9i / 50-150
    52.9i / 55-165
    652.9i / 75-225

    The 52.9i's are 5-1/4". So far I'm very happy with the speakers. I just think they could use a little more power.

    Look for an A8/S8 D2 amp. More power and plug/play!
