this batt/cap does really help....a big improvement in sound... Its much cleaner and no lights dimming..also help u out when ur battery's dead..had no batt hook up and still can start my car... Its way better then any farad cap out there
For being the smallest battery out of the bunch this really juices my lanzar 1200 and makes my almani 12's pound A GREAT BUY AND PUTS ANY CAP TO SHAME ITS THE CAP KILLER
With any addition of an extra battery you're going to want a battery isolator. Shut switch off when vehicle not in use. Increase both your batteries life and if something goes wrong under the hood the switch will short and wont ruin your system, and vice versa. Overall an excellent addition to any system.
the cap killer i took my out my old system that was in a car i sold 2 hc 600s, had them sitting around so i was in a pinch with the riding mower and kenetic ran my mower "wow" better than the regular/bigger battery came with it. I have the 2 hc 600s running as the primary starting battery for my 2005 mazda rx-8 , cap killer indeed. in my opinion aswell as kenetis speaks for itself THE BEST DAMN BATTERY PERIOD
I use this batter as my second battery in my 07 accord. My sound system would kill my battery without it.
