EdgarG0721 Posted August 27, 2011 Report Share Posted August 27, 2011 (edited) Ok so I have to dual.7 dc xl 12 an I'm looking to upgrade my amp. For electrical I have 2 d3100 right now an dc power Alt 270. I was thinking bout a dc 5k but my rise is almost at 2 ohms so I won't get all the power out of it so what about a dc 7.5k? I know it's more power but after u set the gain for clipping do u still get 7.5k at 1 ohm? Or any amp in general after you set the gains do they still rated Help guys !

EdgarG0721 Posted August 27, 2011 Author Report Share Posted August 27, 2011 If I have 2 I would get another d3100 from xs power I can't add another Alt. Quote Link to comment Share on other sites More sharing options...
Blazer Boy280 Posted August 27, 2011 Report Share Posted August 27, 2011 it sounds like you need the 7.5k so get it Quote My Build:Blazer Got Bass Link to comment Share on other sites More sharing options...
EdgarG0721 Posted August 27, 2011 Author Report Share Posted August 27, 2011 Would 2 3.5k be more efficient n is it safe to start them at .7 ohm before rise? Quote Link to comment Share on other sites More sharing options...
RickyFriery97 Posted August 27, 2011 Report Share Posted August 27, 2011 Would 2 3.5k be more efficient n is it safe to start them at .7 ohm before rise? with 2 3.5ks, if you strapped them at .7 that would be .35 per amp, i wouldnt run that low, espically daily Quote 2014 Chevy Silverado Crewcab 1994 Chevy Full Size blazer Link to comment Share on other sites More sharing options...
EdgarG0721 Posted August 27, 2011 Author Report Share Posted August 27, 2011 I tought if I wire them series/ parallel both subs I end with a .7 load when u strap them ? Is my math wrong? I get confused with ohms Quote Link to comment Share on other sites More sharing options...

I get confused with ohms with strapped amps, your final ohm load is divided between the two amps. so if you strap @.7 ohm, each amp will see .35 ohm before rise Quote 2014 Chevy Silverado Crewcab 1994 Chevy Full Size blazer Link to comment Share on other sites More sharing options...
CJ18 Posted August 27, 2011 Report Share Posted August 27, 2011 Honestly i would just stick with the 5k. When dealing with a daily setup I would not count on rise at any point because it changes with every frequency played. Quote Link to comment Share on other sites More sharing options...
