    Which is louder: 2 Alpine Type Es or 2 Kappa Perfects?

    Hey,

    My brother has dual 10" Alpine Type-E subs in a sealed enclosure with 500 rms going to 'em (250 each). Surprisingly, they're really loud.... He just bought them at circuit city because he wanted something kinda loud and with a good warrantee, and I gotta say, they really hit hard. I haven't heard that many systems though. But you can really feel it in your chest and the whole car (dash, doors, pretty much everything) rattles pretty badly.

    I bought a single 12" Infinity Kappa Perfect dual-voice coil sub and right now I'm powering it with a little Jensen amp that's probably doing about 175 rms or less, so right now I just pretty much want something to thump until my spring upgrade. When it warms up I'm gonna be buying another Perfect, get a dual sealed box (1 cubic foot for each of 'em) and run them off of a jbl 600.1 amp, giving each 300-350 rms. How loud will that be in comparison to the Type-E's? I'm pretty sure it should sound a lot better, but I'm just curious right now as to how loud it's actually going to get. With more watts and bigger subs I'd think mine would be louder, but I know Perfects are made for quality and not really loudness.

    What do you guys think? Thanks for any replies,
    - Dane

    1) If you do get another DVC Perfect, I recommend against the JBL BP600.1 and rather recommend a 2-channel amplifier bridged in parallel-series for a 4 ohm load (i.e. Soundstream Rubicon 500-2, Kicker KX550.2, MTX T502, etc.) or a mono amplifier that is more reliable at 1 ohm (i.e. Soundstream Rubicon 500-1)

    2) If you want to be louder than him, using a ported enclosure would definitely push the odds in your favour ...
    Never really thought about your first point before.... Is a 1-ohm load not stable? How will the sound be affected by running the amp at 1 ohm? Thanks for the reply.

    It won't effect the sound running it at 1 ohm but it will be more likely to overheat. The amps are 1 ohm stable from what I know but with longer periods of play they can get hot.
