I agree with the JL VRs... i had the 6" VR 2 way in my rear of my delsol and the TR splits at the front and it sounded great (for my standards) running from the headunit..

atleast 2 of my mates have the VR 6" splits (600Csi) in their car running from amps (cadence and alpine respectively) and they sound tops! quality sound from quality speakers
