I am trying to pair a Velodyne SPL 800 plate amplifier to a 10" SPL sub, which I purchased separately. I assumed it would be straightforward, however, I’m not sure how to hook to accelerometer to the plate amp. The accelerometer wire/plug coming off of the speaker looks like others I’ve seen on various Velodyne’s (4 pin connector), but I don’t see a place on the plate amp to connect it. Anyone have a SPL-800 and can tell me how the speaker is wired amp? Any help would be appreciated
