just did the install today
Eclipse 8445 HU, Focal 165K2P, Audison Lrx 2.150, crossfire vrd-1000, 4x JL 10w3v2D2 sealed, dual optima red tops, one under the hood the other under the driver seat, the car is also sitting on airbags too

i'm gonna just link them all at once, but its pics of the vehicle, the two batteries, HU, subs, wall that hides my air tank, and the valve controls

 

got enough bass? looks like a crazy setup. How are the red-tops working for you?

 

i keep the bass down a bit, only want it loud when its needed, as for the redtops, i've always used one under the hood, but the battery under the seat used to be a yellowtop, however the previous owner said he'd been through 3 yellowtops since he bought it, they keep having cells go bad
