What is good for a 2001 Silverado extended cab?

[Aleks]

I own a 2001 silverado extended cab. I have a Hifonics brutus 1208d 2 channel and a DHD 1600 watt 2 channel, and 2 w6's but only want to use one. I also have an Alpine mrp-m200 4 channel. i am also going to run a Blackmore epicenter and a clarion 5 band equalizer with a vrxd765 clarion headunit. Should i use the hifonics or the dhd? Use 1 w6 or buy a pioneer slim? what brand speakers for the alpine? What should i dO???
