Hey, seriously. Maybe Norm can back me up on this but if you are running all four woofers on the same 2 amp channels, in parallel, you drop your load in half & double the current output for any given voltage/volume. Keep a close eye on things & make sure sh!+ doesn't heat up on you & fry. You should play that thing in your garage for a couple of days to see what's up & never leave it plugged in for long periods, unattended....just in case.
Other than that, DOPE F-en MOD, now bling that F()ck#R up with LEDs.....
