Well mostly correct... But the capacitor will still help put power to the subs! >>>>My question is<<<<Rockford says thier capacitor puts up to twice the wats going into the subs...WTF? How is this possible? Even if you have a 5ferid power cap on a 500/1 JL I dont see how its gonna MAKE the amp push more power. The 500/1 JL amp has a 950 wat peek, if the cap makes the amp push this all the time..... BYE BYE AMP! I think its just a company bull****ing to sell a product for more than the other guys, but its the exact same product!
