Sub woofer to go with amp

This question is answered

i have a Kenwood KAC-7285 amp 600w

i recently blew out my sub, probably cause it was too loud.

So im looking for a new one that my amp will not blow out

what would be a good sub for it.

i prefer a 12 inch sub, but open to other suggestions.

i would need a case most likely too.

i listen to rap, and electronic music if that helps.

it is a honda civic 97 coupe.

any help would be appreciated thanks !

  • Amp is 150W RMS x2 @4-ohms, 300Wx2@2-ohms, 600W RMS @4-ohms bridged.

    Good subs would be a 500-600W RMS DVC-2-ohm or SVC-4-ohm model.

    Alpine Type R - SWR-1223D would be good.

    Typically you blow subs by setting the gain too high and sending a clipped signal to the sub.  If you want a sub that that amp will not blow out (Ever), look for a sub that handles genuine 3000W RMS - but it won't sound good with your amp.

  • Are there any other subs you would recommend?

    something less expensive ah

  • You want a subwoofer in a box for less than $200 ?

    This should slam pretty hard with that amp - http://www.crutchfield.com/p_777B24/Sound-Ordnance-B-24.html?tp=112

  • i still havent decided on which sub to buy,

    im thinking on the one tigerheli recommended, but should i get the 4 ohm or the 2 ohm sub?

    this is my first system and im dont wanna mess with it

    with my old sub i had the amp wired on bridged, but im not really sure whats the difference.

    any advice on that?

  • Ideally, you want a mono amp for subs, but what you have is a 2-channel.

    You would want to bridge the 2-channel amp, which means you want a 4-ohm load, which means you want either an SVC-4-ohm or DVC-2-ohm subwoofer, which is what I listed.

  • The Alpine SWR-1223D subwoofer is a DVC 2-ohm's per voice coil subwoofer. When you wire the 2 voice coils in series, you will get a 4 ohm load which will work with the bridged output of the Kenwood amp.

    That subwoofer works in a variety of box sizes so if the one you blew is a 12" subwoofer then you should be able to re-use the box.

  • thanks for the help guys, i ordered the apline swr-1223d. 

    so when buying a sub for a certain amp, do i wanna match up ohms and rms?

    Yes - if you understand the concepts.

    My initial reply spelled it out, but ...

    Your amp makes the most RMS (600W) with both channels bridged to a 4-ohm load.

    So you want a sub that handles 600W RMS at 4-ohms.

    For a single sub, that would be either an SVC-4-ohm sub or a DVC-2-ohm sub.

    (This assumes the subs and amps are rated accurately, but many companies sell 600W RMS subs that only handle 150W RMS and a few companies sell 600W RMS amps that do more like 900W RMS.)  Alpine and Kenwood are pretty straight-up, but be careful with some of the non-CF budget brands.

    Hope This Helps!!!
