Is the shaker 1000 worth the extra $1295? My current car is a 2003 BMW 540 with an aftermarket sound system; diamond audio speakers, jl audio subs, jl audio amps. My other car is a 2009 Mazda CX9 with the Bose system. For a stock unit, I am impressed with the Bose system in the Mazda.
Do I need to upgrade to the shaker 1000 to get it comparable to the Bose?
