So how is it after 3 years of owning the boat I just noticed this cut out under the salon seat...and guess what I found inside!
Anyone have any experience or info on these units?
I'm familiar with them. I have two although the hook ups look a bit different then mine. Looks like they are running additional speakers off of it instead of from the receiver which can be done but I'm not a huge fan of doing it that way. Have you traced those wires?
Near as I can tell the right and left channels go from the receiver to the sub woofer and out to the speakers with left and right sides each having 2 speakers in parallel. The whole boat is now on an inverter so the sub should be on but I need to mess with the wiring and confirm that. I could never get my center channel speaker to work (removed now for drawers) and I don't see how it wired in. Do you think this thing is actually a real sub woofer - you can't see anything in there and there is no way it is ever coming out. Here is a better pic.
Yes it is a powered sub so it has an amp to drive the sub built in. The sub is either in the front or it is underneath and is a down firing sub. I believe it should have another input cable going to it for signal to the sub.
Yup, it is missing the inputs from the head unit (receiver). Those two RCA jacks, red and white, are the inputs. It is also A/C powered so will only work when connected to shore power of it it's wired to an inverter.
This is actually a pretty good idea as long as you can provide ac power to the sub at all times. I'm thinking it should work fine once the correct inputs are connected. I'm assuming that a dc stereo would pre amp the same way as an ac stereo.
