Right now in my car I have a Panasonic deck with 6.5" focal polyglass components in the front 165v2 (75-100 rms) and 5.25" focal polyglass components in the back (75-100rms) with 3 jl audio 12w0's (125-150 rms) and a rockford fosgate punch 500s. My amplifier cant handle 3 of them just 2, unless i parallel wire it at 2 ohms but that would mean i need 1 dual voice coil sub which i'd go with a jl audio 12w3v2. Should I get rid of one of the w0's and get a 12" jl audio w3v2 and a nice 4 chan amplifier to power my mids and highs or should I get a nice 5 channel amplifier and keep the w0. I'm looking for SPL. Please help me out... Email me at email@example.com or post here.
