n8ball2013 Posted July 14, 2012 Report Share Posted July 14, 2012 ive ran at .5ohm for two months daily and never dropped below 13.4 with my voltage. Then you've got stupid rise.

CJ18 Posted July 14, 2012 Report Share Posted July 14, 2012 First let start with what you are trying to do. If you are only running a pair of 600w subs, then this discussion is going to be very simple. You have to plan the entire build based on what subs you want to run. Then you buy and amp that will give you the power you need. Then you make sure your electrical can handle that amp. Quote Link to comment Share on other sites More sharing options...
tacomaguy1 Posted July 14, 2012 Report Share Posted July 14, 2012 crescendo bc series for sure...ran a 3.5 for over a year at .5 and am running a 5.5k at .5 now for a while Quote Team Flex Issues Link to comment Share on other sites More sharing options...
CJ18 Posted July 14, 2012 Report Share Posted July 14, 2012 I also want to clarify something here that I think alot of people either don't know or just don't think about. When you ask about a .5ohm stable amp, the question that you are really asking is if the amp will run at .5ohm reactive, not nominal. Nominal is what you are wired to at the amp before any signal is applied. Reactive is your actual ohm load the amp sees once a signal is applied to the subs. This is where impedance rise comes into play and you have to understand this before you start wiring below 1 ohm. When wiring at .5 ohm nominal on a 1 ohm stable amp, you are relying totally on impedance rise to get you up over 1 ohm reactive so that your amp will stay on and not go into protect.

bighossf150 Posted July 15, 2012 Report Share Posted July 15, 2012 lanzar opti's are .5 ohm stable and put out good power for the price Quote Used to have a loud truck 2009 Corvette Z06, H/C/I, 150 shot, g force tune, 730rwhp/690rwtq 2013 F-150 limited, MPT Tune, leveled on 35"s Link to comment Share on other sites More sharing options...
Radioactiv Posted July 15, 2012 Report Share Posted July 15, 2012 Run my 2500 at half. Box rise is about to 1.5 at where i burp. My electrical isnt great so I never go full tilt on her. Quote 1993 Ford RangerWalkthrough20, North Georgia Link to comment Share on other sites More sharing options...
