Car Stereos: Amp options?, alpine swe, 4x6 speakers

Question
I have Alpine SPS-17C2 6 1/2" speakers in the front door's of my 99 silverado and am going to put Pioneer TS-A4672R 4X6" speakers in the rear. Powered by a 50X4 Pioneer tuner. I would like to put 2 Alpine SWE-1042 subwoofers under the rear seat and was wondering what amp package i should go with to get good sound out of this package?

Answer
Hi Greg.

It mostly depends on your preferences and musical taste, my advice to you would be to go to the nearest car audio shop or any store where they have a display room and have them show you different setups, let your ears pick, and your walet decide, though i can put a lot of packages togheter but you might not be satisfied with the result, just let me know if you couldn't and you still want me to suggest some combos and amp packages, ill be glad to help you.

Regards
