BassHead1990 Posted October 28, 2010 Report Share Posted October 28, 2010 I have an Kenwood X1200M amplifier that seems to look like it has two channels, but it's mono. I figure that most two channel amps have the positive and negative in series (+ -,+ -) but this one has it displayed as (+ +,- -). So it possible that it is a one channel amp set up for dual voice coils, or is two channel spitting the amp up? I also can't tell if this amplifier is 1ohm stable, the manual states that user should use 1ohm and greater subwoofers, but the specifications don't show the RMS rating at 1ohm. The manual shows the amplifier specifications for 2400w max, 1200w @ 2ohm X 1, and 800w @ 4ohm X 1. Just trying to find the right configurations for the best possible outcome.

BassHead1990 Posted October 28, 2010 Author Report Share Posted October 28, 2010 The subwoofers are DVC 4ohm but they are wired in parallel into 2ohms each.

Socky Posted October 28, 2010 Report Share Posted October 28, 2010 By looking at the specs the amp is 1 ohm capable. There is only 1 channel on the the amplifier, it just has 2 pos,negs on it. So most likely you are wired to 1 ohm with both those subs. Make sure you adjust the gain with a dmm or o-scope so you get a clean signal. No bass boost either.

nCOMP1337 Posted October 28, 2010 Report Share Posted October 28, 2010 yea, i used to have the amp it is 1 ohm stable, and i believe it also has the inputs for 2 speakers but i am sure they are not bridged they should function as two different channels even though it is a mono amp, i know my mono rockford fosgate prime 500 amp has 2 channels that are bridged, which i hate, because whatever i input ito it it dropes an ohm load which i didnt want, but it still works just as well i really liked that amp, never gave me an issue, its probably the only series of amp id recommend from kenwood Quote Link to comment Share on other sites More sharing options...
BassHead1990 Posted October 28, 2010 Author Report Share Posted October 28, 2010 Alright thanks, I'm going to have to borrow one from a friend or something because I don't have the funds for one right now. So I should turn the bass boost down on the amp?

nCOMP1337 Posted October 29, 2010 Report Share Posted October 29, 2010 yea, i would go with no bass boost, a smart man once told me, if you cant get the sound out of the subs that you want without adding bass boost or other boost via head unit, then you should probably upgrade your subs not to say you cant have the boosts and the subs will be fine, i guess its users choice i have everything on my head unit set to 0, bass is -2 and bass boost on amp is 0 Quote Link to comment Share on other sites More sharing options...
BassHead1990 Posted October 29, 2010 Author Report Share Posted October 29, 2010 Alright I can try it. I don't see a bass boost on the amp anyways and I have it set at +5 of -15 - +15 on my head Unit Quote (2007 Chevy Tahoe LT) Mechman 320A OEM AGM D'Amore Engineering HLC-2 Sig Converter D'Amore Engineering E1500.1 Fi Audio Neo 3.5 12" Link to comment Share on other sites More sharing options...
Guest Posted October 29, 2010 Report Share Posted October 29, 2010 Alright I can try it. I don't see a bass boost on the amp anyways and I have it set at +5 of -15 - +15 on my head Unit with kenwood decks, SW LVL on +15 is perfectly fine.

BassHead1990 Posted October 29, 2010 Author Report Share Posted October 29, 2010 Cool, Right now I can't even turn it up all the way anyways with the Voltage drop Quote (2007 Chevy Tahoe LT) Mechman 320A OEM AGM D'Amore Engineering HLC-2 Sig Converter D'Amore Engineering E1500.1 Fi Audio Neo 3.5 12" Link to comment Share on other sites More sharing options...
