its cool man. most of my installers at my store don't even realize that. there have been many times that only one voice coil has been hooked up. the jl amps are ideally the best amps to run on their subs. they are some of the cleanest amps on the market. as well as on all of there slash amps they actually put out the same amount of power at 2 ohms that they do at 1 ohm.
