If you wired it down into 1ohm it should hit pretty nicely but not near what they are capable of than with the 500/1 why not either upgrade to the 500/1 or gt the 250/1 and instead a pair of w0s instead.
Don't the Jl mono amps put out the same amount of power from 4ohm - 1ohm. That would make the impedence a null subject. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
