Update. Had a whole bunch of stuff installed today. Unfortuneatly BOTH Kicker amps (the 2 channel refurb I bought on ebay and the 4 channel refurb I bought from consumerdepot.com) are... well, let's just say they're not working. Each time a new fuse is put in they immediately pop. Shop was baffled since they've installed a lot of refurbed kickers... especially with the luck of getting 2 DOA amps from 2 separate venders. (seriously... that' some s*** ass luck if you ask me) So now I gotta return these POS amps and probably pony up some big time retail dough at WorstBuy.
