Thanks. This helps a bunch. I'll let you know how it goesI can't see why not. If it's already hooked up to the 4 main speakers you wouldn't need to change a thing there. You'll use the pre-amp outs on your Kenwood to run to your PS-8 for the signal. There will be a red power with an inline 30A glass fuse to go from your battery to the PS-8. Find a good place to come through the firewall. I went in front of the drivers side above the pedals and under my carpet. Don't run these two side-by-side as it can create interference. There is a blue remote line which if you hook up to the Kenwood and run to the PS-8 will turn on the PS-8 when the Kenwood comes on. It doesn't have to be used but I like it best since there will be a slight delay if you don't. There is a ground wire (which was too short for my install). Make sure and sand off any paint if you ground to painted surfaces. You will need two ring connectors that do not come with the PS-8. One for connecting to the battery terminal and the other for the ground. Pretty straightforward. The instructions were good. Also, there is a sub control knob. I didn't install it at first but did later and am glad I did. It just plugs into the PS-8 and you can mount it wherever it is convenient for you.
