Add Bass/Subwoofer to 2017 Ford Mustang

I bought a 2017 mustang gt with in dash sync/shaker system. It sounds like crap. Wondering if there is an easy way to add bass/amp/subwoofer. I cannot find any wiring info. Dont want to get into replacing the headunit. Looking for suggestions.

Thanks

Frank

Thanks for the info. Another quick question. I see hooking up an amp and subwoofer seems to say to take a left and a right speaker hookup as an input. Do you lose the left and right speakers you choose? Do you hookup the amp with connections from the existing speaker to keep the in operation??

Thanks

The speakers will still work.

The MTX website has options and the live chat techs are always happy to help!

If I find a factory sub woofer, would that be plug and play. Mustang GT convertible?? Thanks
