The base stereo puts out 80 watts peak, the Shaker 500 is rated at 500 watts peak and the Shaker 1000 is rated at 1,000. Does anyone know if the watts are the same for the head units? By this I mean, is it 80 watts for the Shaker 500 head unit which powers the four full range speakers and 420 watts (500 total minus 80 from head unit) from the underdash amps to the two door subwoofers. Following this thinking, the Shaker 1000 would gain its additional 500 watts from the amps in the trunk mounted unit.

i have a similar question, i want to replace my head unit cause all the buttons are worn down. my brother gave me a standard head unit so i wanted to know is the power coming from the head unit or the amps. if i replace my shaker 1000 head unit with the standard one will i lose power.

I highly doubt you will gain any power increases over the regular Shaker 500 Head unit. I wouldn't be surprised if the "true" RMS power is somewhere in the 10 to 15 watt per channel range. I hate to break it to you but the "peak" power figure is somewhat useless unless you are playing a numbers game.

I am afraid the standard radio will be missing the controls for the door and trunk mounted subwoofers. The radio powers the door speakers but all of the subwoofers are powered by little IC amplifiers.

Look on your driver's side kick panel and you will find something similar to this for the door mounted subwoofers:

This is what one of the Shaker 500 amplifiers looks like on the inside: http://i24.photobucket.com/albums/c4.../Internals.jpg

IIRC the amplifier that powers the trunk mounted subwoofers is mounted on the enclosure in the trunk. My 2006 GT only had the Shaker 500 so I can't comment on the 1000's sub.
