[QUOTE="hispls, post: 8649845, member: 614752"] You really should not be opening 100A fuses on a 1200W rated amp. This is a red flag for me. Look at the Kicker power ratings: @ 14.4V, 4Ω mono, ≤ 1% THD+N : 600 x 1 @ 14.4V, 2Ω mono, ≤ 1% THD+N : 1200 x 1 @ 14.4V, 1Ω mono, ≤ 1% THD+N : +/- 10% WTF is +/- 10%? Whatever it is, that's not a proper 1 ohm rating and if it'll make its rated power at 2 ohm there's probably where you want to operate to be safe. As you drop impedance efficiency goes out the window (opening 100A fuses) and it is very rough on electronics particularly if the amp isn't purpose built for competition tier abuse. Sounds to me like an amp that's meant to drive 2 ohm. I used to run Kicker ZR and the very early KX series I drove at low impedance and they did get protect happy when you pushed things. Depending on the subs/box they'd even stay out of protect most of the time, but they did protect here and there. I'd audition some subs that you can wire to a 2 ohm load and see what happens. More worrying is if you're pushing this thing into protect and drop into 2 ohm sub load you may or may not be satisfied with the output which puts you in a real bind because adding power seems impractical for you and who knows how much volume you have for a big sub box or bigger subs?
