So to recap, what I think you are planning (please advise if wrong):
(Copied from another thread)
I believe the front mids and tweeters are powered individually. The rears would be replaced with coaxials. Two 12" subs. No more center channel.
Front mids and tweets and rears, I still need details since I'm not sure if it's a 6 channel amp. Based on their configuration it seems this would fit the VX600/6i. The subs, I assuming I'll get the VX1000 since they mentioned 1000 watts.
I estimated the setup would be around 5 grand and it is.
A) Front A Pillar Tweeters: Replace with Tweeters
B) Front Door Woofers: Replace with Mid-ranges (Woofers?)
C) Rear Door Woofers: Replace with Co-axials
D) Rear C Pillar Mid-ranges: Disconnected
E) Center Channel: Disconnected
F) OEM Subwoofer: Removed
Adding (All prices per Crutchfield.com):
JL VX600/6i, DSP Amp, 75wpc x 6 (Powering A), B), & C) actively using DSP, (Cost $1,200)
OPTION 1: JL VX1000/1i DSP Amp, 1000w x 1 @ 2ohms, (Cost $1,100) + Qty (2) JL Audio 12W6v3-D4 (Cost $1,460 both) = (OPTION 1 TOTAL: $2,560)

Plus whatever the labor, installation, DSP tuning, wiring, sound deadening and custom fabricated double Sub box) - My guess would be $2,500 to $3,000 for a
Grand Total between $6,000 to $8,000!
