Review: Massive capacity. Excellent for car audio. - Still going strong, and I bought another set of these to acompany a system change to 14000 watts . These are real and powerful .......Buy these for your car audio system. These caps were a major game changer for a 10000 watt system. Hands down worth the investment. You don't realize how much 3400 Farad is until you charge and discharge these capacitors. Each Capacitor charged smoothly witout any problems. The capacitors each have about a final 6 to 14 ma draw at full charge. The 6 capacitors in series still pack a punch of about 566 Farads (in theory) . These capacitors are not toys and can cause serious damage if shorted . Curious on capacity , I powered 2 driving lights at 4.4 A total @ 13.4 V (filament bulbs) and after 2 hours I still had 12.9 V(initial charge was 13.5 V). I left them connected to the capacitors longer , but I fell asleep ! When I woke up at 5am the next morning, I checked on the lights and was amazed they were still on ! I figured they'd be totally discharged, but the capacitors still had 5.6 V from the initial connection at 9 pm. These caps were a major game changer for my system which includes a higher capacity alternator (400amp) and (4) XS Power 3300 amp agm batteries (skip the regular flooded batteries) . (4) Sundown X series subs (1) X18 and (3) X15 .Each sub has its own 3000 rms watt amp @1 ohm. 0 awg minimum for wiring. Subs are wired with 8awg to amps. Mids and Highs have 2 dedicated 1000 watt rms amps with 12 awg minimum speaker wire connections .I'll probably add another X18 , battery,capacitor assembly ,and another alternator .
