Hooking up electric guitar to a commercial stereo amp and speaker set up?

I'm installing a stereo system into my garage and I'm curious if it will work with my guitar if I wanted to hook it up, mainly the amp. I have two crown cdi 1000 amps that will be wired to 4 huge hanging jbl 60 series speakers as well as 2 smaller jbl tweeters. It's a hard wired system so I would need to make an adapter to go from the terminals to a quarter inch cable to go into the guitar. I know the set up is not meant for a guitar but will it work? Do you think it will sound good?

Thanks
