Got my Kicker Keyloc DSP Sunday and installed it yesterday. Got a lot of feedback from forum members on what DSP to run and ultimately went with this one because I have a PSU300acd already installed. Because of that (you will see from the pictures) The wiring to add this to my system was very very simple. The PSU has several connection options that comes included. One is an RCA out connection option for aftermarket amps. So all I really had to do was connect the Kicker wires to some female RCA and clip in the included male attachment from Alpine. Ran a 1.5ft cable from dsp to the sub, which was perfect. I wanted it under the seat but there is not enough room so I put it in the center console. Ran an add a fuse to #45 spot for power (its only a 2amp fuse) I did not have time to set it up yesterday just got it installed. I also forgot until writing this, that I need to switch the breaker to RCA on the PSU as well, but thats ok because as you can see from the pics, the RCA is very close to the frame rail of the seat. If i put the plastic cover on, the clip is actually right above the L (white) RCA and pushes it down a little. I ordered some 90deg RCA connectors from Amazon that will be here today to fix that. It will also give me a little more slack in that RCA cable ( it fits perfect but there is basically no slack. I will update with the dsp setup later today.
