Hi everyone. I am new to this forum and need some help/advise. I am recently have stock 3.5 on the dash, and 6x9's on the front doors and rears. I am planning to do an upgrade. I currently have 2 12BL's in a ported box tuned to 31hz running off BC2000D amp. I was thinking of upgrading the 6x9's on the front doors and the 3.5's on the dash with PWX6.5's and RTS-1 tweeters both running off the S800.4 from Crescendo. Disabling the rears. Is this setup ok as an upgrade? I was just running stocks with 2 12jl audio w6v2's for bass in a ported box. Just wanted to get different set of subs and a better front stage. Any advise will help.
