I'm new so bear with my stupidity

I just purchased a 2000 Maxima SE w/ Bose system. I would like to keep the Bose speakers, but I would like to change out the radio.

I purchased a Alpine IDA-X305S (http://www.newegg.com/Product/Produc...9SIA16R0BW1047) and want to put it in.

My question is can I keep the Bose speakers? Will it work fine with my new radio? Are there any other things I need to purchase to optimize sound quality and installation?

Your advise is greatly appreciated.

Thanks in advance!
