Need help coosing an amplifer for my speakers & sub please!!
 

I have an 07 Dodge Ram 3500 Mega Cab

My head unit is:
- Kenwood KDC-BT852HD. Which is 50W x 4

In my front doors I have:
- Alpine Type R SPR-69 speakers. Which is RMS 100w & Peak 300w

In the rear doors I have:
- Alpine Type R SPR-60 which is RMS 100w & Peak 300w

For my sub I have:
- Alpine Type R SWR-12D2 which is RMS 1000w and Peak 3000w

Now I need help on choosing an amp to power everything and I`d like to
get the most out of all 4 speakers and sub.

I suppose I should get an Alpine amp? An all Alpine system? If not what other amps are good? Please list the model number or link to it
Also I`m not sure if I should get one or two amps, one for the speakers and one for the sub?

I`d like to buy the amplifier from Best Buy sense I have a gift card.
So please help me pick out an amp off of bestbuy.com
Thanks!

You can get better and cheaper if you want to buy else where, let me know, I can make suggestions.

Yeah I'm open minded to other brands and stores, I should have said that also. Thanks for your help

For the speakers Rockford Fosgate T400-4 Power Series Compact 4-Channel Amplifier

For sub Rockford Fosgate T1000-1bdCP (t10001bdcp) (2010 Model) 1000W RMS

Sorry, for the front speakers it should be the Rockford Fosgate T600-4 Power Series Compact 4-Channel Amplifier

For the front speakers? They would be be good for all 4 speakers right?
