NESA DVD-7000T and Addvision AV-56 - $300 for the pair, retail probably around $700

Heres a proposal for you,

Phoenix Gold T600.4
onlinecarstereo.com = 319.00

CDT CL61 fronts
Thezeb.com = 150.00

CDT CL6 rear fill
Thezeb.com = 78.00

CDA 9830 HU
onlinecarstereo.com = 269.00

Total $816 leaves approx $200 for wires and install, may need alittle more.
fronts, rears, 4 channel amp.
Fronts off 2 channels of the amp.
Rears off deck for fill
2 channels of the deck left to add a subwoofer later on, at 300w rms.
