I was thinking of upgrading all speakers in the car and adding a sub in the trunk. I'm getting the GT Premium, which comes with a Shaker 500. Any idea if the Shaker amps are enough to push everything except for the door woofers and additional sub? I am thinking of having a seperate amp for the door woofers and the sub in the trunk and running everything else on the stock amp. I will be keeping the head unit, because it's the nav system. Anyone have any input on this?
It all depends on the speakers you choose, but I think you'll be very bass heavy. I don't know what the real world wattage of the shaker amps are but I doubt they're much at all.
