Default Help with power requirements

I'm upgrading my stock system , '01 Silverado ext cab , and need a little help with the power needs. Using the bcae1 chart , it looks like I can use 4 awg from the battery to a DB and then split with 4 + 8 to two amps . The total current draw would be 130a. I plan to upgrade the Big 3 , but my stock alt. may just be 105a, not 130a, but I'm not not sure what I have. I'm not one to run my music at full vol. so I'm thinking this may help matters.

System spec's:
Alpine-CDA-105
Alpine-MRP-F300
Clarion-DPX2251
Infinity components speakers front/rear
REF 6030CS
REF 6432CFP
Infinity 2x 10" subs , Infinity-1052w
Down firing box under the rear seat.

I'm planning to bridge the Clarion 600 x1 @4 ohm to the two subs.

Does a 4 awg kit look okay? Will I need to upgrade the alternator?

Any comments are welcomed.
