They say the old kickers like mine are 1ohm stable, the guy i bought these 2 off of said he ran them at 1ohm, i got a sub i put it at 1 and before you even get it working it clips off. why the heck would it do that unless it's not stable at 1. i have good electrical. It's a 15" dc lvl4 w/ lvl 5 soft parts. box is way to small could that have anything to do with it? thanks for any answers.
