I have a 05CC and I'm looking for some info on doing a cut thru. Would like to run 4 12s or 2 15s (which would you go with and why?) have'nt made up my mind yet but all of my past systems used 12s. Already bought MB Quart componets for each door and a 475watt infinity amp to power them. Time to figure out what to do with the rest of the system. Thanks for any help.
