    Default What is the best amp for Polk Audio db651,db691?what Sub,Amp can go with them?

    I have an kenwood excelon x493 as the head unit.I have the regular db651 not components.Will these be almost as good with or w/o an amp?As for the 691's can they be ran at 2 ohms?The reason i ask this is because i've seen amps with 50-80 rms x 1 channel @ 4ohms for the 651's and 125 x 1 @ 2 ohms and the 691's are 100w rms.Can it push the 691's ok without under-powering/overpowering them?The amps i've look at are Polk's,alpine,mtx,and a few others...Thanks In Advance!

    Your speakers are 4 ohm speakers. There is no changing that. The way you wire the speakers will determine what the ohm rating of the amp will be.

    Do a little research on wiring speakers to an amp and decide what you want to do. Crutchfield usually has some good information.

    As far as 125x1, if that were run to 2 speakers, each one would be getting half of that power, so it would still be in the 50-80 range per speaker. All you did was force the amp to work at a lower ohm rating, which results in more heat.

    I love Polk Audio PA500.4 amp.
    90Wx4 at 4ohms is just what your 100W speakers need

    The three companies you listed all make good amps. A 4 channel amp is the way I would go. Do some online shopping and see if you can find some better prices than the shops offer.

    What kind of car are you putting it in? I know a lot of people like rear fill but if SQ is your objective then its not the way to go. If its a small cabin then its definitely not the way to go. A good set of comps would be a better investment than 2 pairs of speakers.
