cloud77 Posted January 22, 2013 Report Share Posted January 22, 2013 you need another battery just for the 1400.2 alone. If the bass cuts out and comes back to power, thats the protection circuitry on the amp saving itself. You are dropping in voltage too low below 11 v. Mmats recommends having another battery just to run these hc amps. Grab up a xs d975, should be a perfect battery for this set up, and this way you will be able to run that 0 neg to the batt neg and do your grounds from there. 2004 Grand Prix GT (2) 12" RE XXXs (04/05 XBL^2) 5 cu. ft tuned @ 35 Hz MMATS HD4000.05 MMATS SQ4100 Infinity Kappa components Juice Box black cherry Duralast platinum group 34 1/0 KNU OFC, 2/0 welding Singer 250A Link to comment Share on other sites More sharing options...
