This a quick and simple setup we did a few weeks ago. All the equipment is from our clearance/old stock pile.
Factory radio
Kicker RS65.2 components in the doors
Factory 6x9's on radio power
Focal Polyglass 33v1
Focal Solid 4 bridged on doors
Focal Solid 1 for sub
Ground Zero GZDM 1850ML deadener
Like I said, simple little setup that sounds worlds better than it did stock and on a very tight budget. Customer was more than pleased with the results.
