Best Amp/Sub for the money

Trucks a quad cab so obviously space is limited behind the rear seats. My box looks like it'll accept a woofer up to 5 7/8" mounting depth. In your opinion what the better amp as well as sub.

AMPS:
1) Alpine MRP-M1000
2) Kenwood KAC8105D
3) Boston Acoustics GTA-800M

SUBS:
1) Alpine SWR-1023D Type R
2) Boston Acoustics G110-4

I listen to a wide range of music, however I'm looking for a sub that'll compromise a bit of everything... great sound, deep bass though sounds tight and crisp when listing to acoustic music.

 

I have kicker subs in my truck..I listen to every type of music and they seem to go well with everything. I have not even adjusted then since day 1. I run a JBL amp

 

you should look at kicker zx750.1 Them are beast, ive got one and its awesome. (Also its for sale)

 

Maybe check out the Elemental Designs 11Kv.2 Subwoofer.
