have an 06 mustang conv, kenwood double din, i am thinking of just a 3 way set of dynaudio 360 in front with 300rms amp to the set, with the 8" woofer and 3" mid bass will i be able to have any kind of quality sound and bass, with out a sub? also i would be willing to add some midwoofer in the back seat if this would help the bass some, just do not like a lot of thump, and do not like taking up what little trunk i have!
Just get a seperate 8" sub and amp that...they can be built to pretty small enclosure specs and still add some good bass to your system without overpowering anything.
If that doesnt work..kicker sells a package of (2) 6-3/4" Subs...probably would sound alright. I have an 8" kicker comp sub runnin from a JL 1200 E (200w) and it sounds REALLY really good.
