Looks like it could be fun. mt buddy had his 3000 2 18's and i had 2 ap1500d's on my 18 btl with one c&d battery as well but it won't do as bad as you think. won't be great but won't be bad! hope to see it finished:)
I bought my 300/2 off of this forum and have never had any problem with it! I had cdt's also fyi. But for the record I didn't pay even close to full price FTW!
It's the slow one so no motor mods just a bunch of stereo stuff! Can't break anything too expensive with speakers, but I have a heavy foot so I'm glad I got the slow one! lol
