Amp & Xplod Confusion

I've occasionally heard that Xplod prices are too much brand and not enough quality to go with it. My interest is in a Sony Xplod CDX-MP70 reciever. Does that G-Protection do what it claims it can?

For a changer, I am looking at a CDX-757MX. It will have to go in my trunk. Can it withstand (2) Type-R Alpine 10s at about 250-300watts without skipping? If not, what MP3 changer would be able to?

What would be the ideal setup to push (2) Apline Type-R 10s with 300RMS-1000MAX? Run both with one amp or bridge an amp for each one? Run series or parallel?

Alot of questions, but all pertain to one setup. Thanx in advance.
