    Should they replace the sub that you overpowered?

    450 isn't really overpowering dude... its reasonable power for the speaker provided it was in a 0.88 cubic foot sealed enclosure.

    400 rms / 800 max does not mean you can put 800 rms into it.

    400 rms IS 800 max... max = peak.

    wattage = voltage squared / resistance.

    rms wattage = 0.707 * 0.707 * voltage squared / resistance.

    0.707 * .707 = 0.5 ... so half.

    therefore... 450 rms is 900 peak.

    so you were overpowering the speaker.

    and don't argue with me, i'm not explaining it any further, get a clue.

    however, years of experience tell me that if the new momo is more like the generation 1 and 2 momo, then you can probably dump 5 or 600 watts on it.

    if it's more like the old DB and DX stuff, then even though its rated at 400, you shouldn't break 350 on it.

    take it, chew on it - and call polk you turkey, 1-800-whatever polk's number is. if you ahve a receipt and you bought it from a real store or crutchfield or sounddomain, i'm sure they'll take care of you -- if you bought it from tony the fish at the flea market then forget about it, you can choke on it.

    Its not always a point of using too big an amp. You couldve also had the gains set too high and momentarily clipped the amp sending about 900 watts to the 400 watt sub and subsequently killed it.

    Or you couldve just had the bad luck of buying a lemon. It happens from time to time to everybody.

    Something sounds fishy to me. An 8 ohm sub wouldve been getting HALF what the Polks were getting so they shouldnt be blowing. What amp are you running? Something else could be wrong.

    If the fuses on the amp were blown then your problem isnt with the speakers. The first thing you should check is your wiring. Is your power wire fused before the firewall?

    Even if it is, it could be arcing somewhere between the firewall and the amp and sending a pretty large surge to the amp. Your amps fuses could pop but not before your amp makes a pretty big burp of power and that could be the culprit.

    OK, something isn't right. If you're running two Polk 12"DVC's, they should be wired for a 4ohm load, and run the Kenwood bridged at 460x1 at 4ohms.

    I think you've got your subs wired for a less than 4ohm load. I've got the 7201 and its a great amp.

    If I remember right, this came up in an eariler post and he has them wired right. Theyre DVC subs and he has each sub wired in series and then both wired in parallel with the amp for a 4 ohm mono load.

    The gain is a little high, it shouldnt be over half but I still kinda think either something is wrong with the amp or the power running to the amp. Maybe you should dump that cap and see how things run. Caps are a scam.

    I had mine set at the 11:30 position (just under half). Hmm, I'd doublecheck your ground wire and power wires going to the amp. Make sure the ground wire makes a metal on metal connection and not a metal on painted metal connection.

    A good strong battery will stop your lights from dimming. A 450 watt amp is nowhere big enough to require a cap. Im running over 700 watts RMS and using the bone stock charging system with zero problems.

    What size power and ground wire you running? It's need to be at least 8 gauge.

    hmm... i'm not against caps, but you may wish to try it without... i'm pulling nearly 2kW, and i don't get headlight dimming at ALL...

    I don't believe caps are a scam. I think they can mildly help but a better battery is definitely the better idea (other than upgrading an alternator). Not only does a cap help a little with the instant bursts but mainly I like them for the filtration they do to the power. If theres any kind of issues with your lines, they help clean the distortion out of the power which usually is a problem in a mobile system. But by no means do I think its necessary on a 450w kenwood.

    i had 2 amps hooked up at once pushing a little over 1000 watts.And i bought the cap for that reason. im done with the other amp until i get a better one for my highs but i paid 160 for my cap and i dont want to waste it sitting around. You know wat i mean?
