I have the high pass set at around 120hz to try and get more volume output from the speakers. I'm not using an eq at the moment although with the lack of clarity i'm getting i'm debating it. i set the ipods eq to flat and run the head unit with a bass at flat usually scoop the mids down a bit and the highs at flat as well.
If im reading this correctly, it sounds like you have 6.5's and 8's wired together and sharing an amp chnl and each zone of the houseboat is off one chnl of the amp. If so:
1) its not the best idea to mix dissimilar speakers on the same amp chnl as they do not sum and share power the same.
2) the 6.5's and 8's really need to be x-overed differently to get the most out of them. They need to be on different halves of a 4-chnl to do this.
3) if a single amp chnl is a different zone of the boat, then you have lost stereo.
I would consider powering each zone with its own amp and using a simple RCA POT on each one as you volume control. If the zone has both 6.5 and 8" speakers, then use a 4 chnl. It is only has 6.5's or 8's, the use a 2chnl
