Only issue I see is that you are shy a channel pair. The passive crossover on the hsk163 have the 3" and tweet as a channel and the 6.5" as another channel. The rear coaxial is a channel and the mono sub out is the last of it. 2 channel pairs up front, a channel pair for rear and a sub is 7 channels. Unless they are planning to run the coaxial off the head unit. Everything else looks good.They are sold locally by Spade Kreations. They are located on the NW side of Cincy. Here's what he just recommended for my car.
Hertz HSK-163.4 3 way component set (front)
Hertz HCX-130.4 2 way coaxial pair (rear)
Hertz HDP-5 5 channel amplifier
Hertz HRC sub level controller
Hertz ES-250.4 10" sub x2 or ES-200.4 8" sub x 2 Depth permitting
Thanks for the feedback. I can't tell you how frustrating it has been not to find a shop in Cincinnati that comes recommended. Have you had any good experiences?If you're looking to have Spade install everything, I would look elsewhere. They will do a rush job on your car and cut corners to take care of the dope boy cars they do. If you're just looking to purchase, I would still shop around and get some prices.
