Im going to look at a jl 18w6 on sunday, and im wondering what i should decide. I can either get a jl !8w6 with a powerful amp (Slash 1000v2), or i can take an offer, offered by my local car audio store. A Jx 1000 amp for $350, and he said he would sell me 2 12w3v3 subs with a box for $400. The 18" sub is in jl recomended deminsions. it will fit in my trunk, it just could stand up. Do you guys prefer 2 12" subs or 1 18" sub? I like sound quality, also, with a very low bass. i have a rockford renegade 850s amp right now, and im planning on getting a new amp. would you recommend a slash or a jx amp? i have a 97 corolla, so space is sort of an issue.
