I bought the SSV components bare (no speakers) and loaded them with exactly what I wanted, which was fosgate coaxes, JL sub, JL amp. Mines a max, so I also added JL coaxes for the rear.
I had the SSV overhead in my RZR and it's more than adequate for most people, but I'm sure it doesn't compare to the audioformz for an overhead system. However, my advice as an audio engineer and designer....For best sound the speakers should create a soundstage in FRONT of you not above or behind you. That being said good sound and bad sound is very subjective and many people are happy with the sound quality of their systems just because it's theirs, and it should be about whatever makes you happy.
