Will this system work well?

db 6501 4ohm in the doors and tweeter locations.Polk Audio db6501 6-1/2" component speaker system — also fit 6-3/4" openings - Reviews at Crutchfield.com

a JL audio 500/3 amp XD500/3 - Car Audio - Amplifiers - XD - JL Audio

and a JL 10w3 2 ohm in the Magic CAS corner box in back 10W3v3-2 - Car Audio - Subwoofer Drivers - W3v3 - JL Audio

The JL 500/3 should put out:

75w x 2 @ 4ohms to the db6501s and
300w x 1 @ 2 ohm to the 10w3 sub

does this all look alright?

I currently have the db6501s running off a 75x2 Polk amp, which I plan to sell. Trying to avoid adding another amp, by getting the 3 chanel JL amp.
