new amp

hi, i have got two twelve w3s and i am considering a new amp. the amp i currently have is a sony 2165-gtx. and i was considering buying a jl amp. the amps i am considering are, the 500/1 and the e1800d. which one should i get? i have heard nothing but good things about the 500/1, but i am wondering what you guys think of the e1800d. any suggestions would be nice. thanks

500/1. still, though, i'd recomend something cheaper than JL that'd perform at par with JL. look into cadence and soundstream.
You should probably even go cheaper, try Directed, Profile, or HiFonics.
