I did all the work myself. The system consists of:
Alpine 7998 head unit
Boston Acoustics Pro Series 6.5 in the front door (using stainless steel baffle
)
Infinity Kappa 572.3 5x7 in the rear doors
Orion 2150SX running fronts
Orion 2250SX running sub
Alpine MRV-T407 running Infinity's
JL audio 18W6 (in about 2cu ft sealed)
Audio Control Matrix 6 channel line driver
Audio Control 24XS crossover for fronts
Plenty of Knukonceptz cable
The amps get pretty warm, but I don't drive it that much, so its not a problem.
