Monsoon stereo as replacement??

I have a standard delco cd player in my 2000 gt. Can I upgrade to a monsoon with the 7 band eq, or do I need to strictly use an amp with that one?

only factory would do a monsoon upgrade, for the same price you could get 10 times the system aftermarket.

yeah but these stereo can be had from ebay for about $150. I just wanted to know if this will work fine without an addition to amps or anything.If it will directly drive my speakers.
