Does anyone know what exactly makes up the Shaker 500 system? The radios look the same. I know the Shaker 500 has the door subs but is it just an amp for the subs and the subs themselves that make it a Shaker 500 over the basic radio? Is it a speaker upgrade in the rear deck and doors as well? Are there other electronics and wiring involved?
I have a 2009 with the 500 and a 2014 with the pro system. The 500 does have door subs that sound amazingly good - do not go for the stock radio or you will be sorry - from all I understand it sounds poor. I'm quite sure the amp for the subs is right in the radio itself. I think the rear speakers are the same for the basic radio as well as the shaker 500 or pro - they are fair at best.
