Would a kenwood x810 Mono Amp be able to power 3 Polk Momo MM12? The kenwood manager told me the amp is stable to 1 ohm and rated at 1600 watts rms. Anyone got info on this?

    was that same store manager snorting lines of crack off his sleeve and then leaning over periodically to sip off his jack-n-coke ?

    Maximum Output power: 1600 Watts x1

    RMS Output:
    Power output@ 2 ohms: 600Wx1
    Power output@ 4 ohms: 300Wx1
    Power output@ 1 ohm: 800Wx1

    got that off a website -- kenwood doesnt' make anything over 1000 watts.. i know that for a fact - i didn't know the exact spec of this but now that i see it, its about identical to the last class D kenwood put out.

    1600 watts is the max power-- the same way my 81000d is "3000 watts max" -- u know how often i see 3000 watts? about as often as the pope gets nookie with a hooker.

    your RMS power at whatever ohm load is what you need to look for.

    800 x 1 at 1 ohm // 600 x 1 at 2 ohms.... 3 momo 12's is 1.33 ohms. so say you'll get like 700 watts. 700 / 3 subs = 233 watts per subwoofer

    233 watts on a momo wont even make the damn thing move. 400+ wasn't enough for the MM12 i demo-ed in my girl's car... 500 - 650 (preferably the 600) is what i would reccomend for a momo... now if you're doing 3 and you're lookin for an amp to run all three... you can get away with like 450 a sub... that's fine... i mean its not like the ideal i'd strive for but hey... sometimes simplicity is the key to happiness.

    so you need like 1400 - 1500 x 1 @ 1.33 ohms.

    amp hunting we go....

    USamps 2000A --- 2000 x 1 at 1 ohm -- that'll blow the momo's right outa their bakets.

    Autotek Stealth 1500.1 --- 1500 x 1 at 1 ohm... 1300 x 1 at 1.33? in that range --- that'll be fine for 3 momo's -- give u like 425 per sub.

    mtx 81000d -- yes the amp that hell forgot -- its rated 2 ohm stable but it'll run down to 1.33 with no problems... not 1... but 1.33... do around 1500 - 1600 at 1.33 // the curve levels off around there.... 500 - 533 per sub -- this is prolly the cheapest amp of the ones i listed.

    ther's a lotta other good amps out there that'll do this job for u...

    just look for 1500 watts around 1.33 ohms --- RMS NOT MAX -- if they wanna give u max.. fine.. 3000 max. :)

    LOL thanks.. actually the 810D is rated at 400 x 1 at 4 800 x 1 at 2 ohms.. I have the x401 powering the 2 momo m12 right now and I have no problems with it.. its WAY TOO LOUD.. but I just want to get MORE HECTIC in my bass.. I had the x401 tested and the meters shows its putting out 396 RMS @ 4 ohms. But I love the MTX 8100. Most of my friends have those powering 3 MTX 8000 subs. But I'm a Polk Momo fiend. Just waiting on my Momo rims for my truck and I will be.. Momofied..
    hey PBD thanks for the reply.. oh yeah its 300 x 1@ 4 ohm and 600 x1 @ 2 ohm..at 12 v.. waht is the difference between rating it at 12 v and 14.4 v? I have a 1999 GMC Yukon and 1 farad cap. Am I giving the amps enough power?

    mtx 810D = 400 / 800 ---- mtx 81000D = 800 / 1500
    the 81000D was replaced by the 1501D -- the 6500D was replaced by the 810D. i know -- stupid numbers...

    mtx 8000's are absolute **** compared to Momo's -- i despise mtx 8000's. the only sub's mtx made that I'd use were the 6000's. I haven't seen/ heard the new 9500 series, but they look semi-promising.

    Momo's are way better.

    12 versus 14 volts... i explained this in another post, but here's the short version... Power = Voltage x Current. So... as voltage increases, so does power (assuming current is constant). raise your voltage by 15-20% --- raise your power by 15-20%.

    this is not a direct correlation since your batteries are not powering your speakers, but it is a "close" approximation.

    the GM truck is going to have at least a 110 - 130 amp alternator... and as a result, you have enough "juice" (Assuming you have a decent 800 - 900 cranking amp battery) to run up to a 1500 watt sub amp and a good sized 4 channel... that's "by the book" -- if you want to push it -- you can dump another battery in there, up your number of caps, and get as much as two 1500 watt amps, a 150 x 2 channel and a 50 x 2 channel (well that's what i'm running off a 117 amp alt , 2 batts, and 3 caps.... although I am kinda pushing it... i have enough "juice" to do normal listening but its pushing it... and i do not have the ability to "burp" it like i'd want to -- my amps are DC-ing out when i slam them).
