why is this in pictures?
and i think its about 1000 extra when you order an 05+

 

It's not in pic's anymore

 

for less than the price of the shaker you get get a small relatively inexpensive sub and amp or powered sub. www.crutchfield.com has a few different enclosures that fit in the same place as the shaker speakers. Plus if you get the shaker i think you would probably have to also upgrade the head unit. since the shaker 500 headunits don't have the SHAKER option that turns the rear speakers on or off.

 

beats me

 

you can find mach 1000 systems under 400 bucks with headunit usually
