Just about all aftermarket head units have a built in amp. Any that do not go out of their way to say they don't.
Will your GS sound fine running off the head unit power only? "Fine" is subjective but I will say no. Plus the head units amp will be designed for 4 speakers only. I personally would get a 5 channel amp or a 4 channel and separate sub amp.
be a way to use the factory amp with an anftermarket head unit too. Look through the ★ 2GS FAQ (Frequently Asked Questions) and DIY Thread ★
The 2GS has 6 speakers, or 7 with the center channel, plus the subwoofer. The front tweeters, if being replaced, are generally run inline with the door speaker so you would count them as one making it 4 speakers + subwoofer. I don't think the center channel will be used by most basic head units.
