K so I've been through alot of brands and vehicles, different styles of boxes, and whatnot.
Deck: JVC KW-NT-800HDT
This remains to be the best and fastest responding deck I have everr used.
Fully Loaded Double DIN and F-A-S-T!!
Amplifiers: Mosconi
4-Channel; Mosconi Gladen AS Series 200.4 (AB Class Amp for 6.5 Compnents)
200 W per channell
2-Channel (Bridged); Gladen AS 300.2 (AB Class Amp For Subwoofer)
1800W 1Channel when Bridged @ 2 ohm.
You might b thinking this is unstable and blah, but i have never had an Amp hit as accuratlely as this (~7Hz the lowest i have gone so far)
Subwoofer: Digital Designs 2512 D4, RMS 800W, Peak 3200W, Travel 66mm (Over 2'', Really cool to watch)
Mid/High; Focal Utopia 6.5'' Components 50th Anniversary Edition
Listened to these on the board next to the Focal Set 2/3s (From 1500-3k/set) and had to have em.
Very smooth and clear, Mids r strong, And highs arent harsh. Very balanced system,
I have to say This is as high as I have gone for quality, but The system i had in this vehicle beforehand gave it a run for its money;
Image Dynamics 6.5's and 12'' with Alpine PDX Amps.
Harsher, not as clear, but SO LOUD
Although I find myself comfortably listening to this stereo, but when i step out of the truck my ears are ringing...
Cant wait to find something louder

Would appreciate any input from people who have also tried these products/brands and a direction to go in next.
