I put my antenna on the top of my custom speaker rack (pictures to follow this afternoon)...I bought the marine kit for the delphi, it works ok, but it cuts out from time to time, I am thinking about changing the antenna to be like the one I have on my Tahoe and see if its any better.... I also bought a cable that fits into the CD Changer port on my Alpine deck and has two RCA outs... from there I go RCA IN to Headphone jack into the side of my Delphi... it works pretty well, although there is some signal loss from the connection of the two cables... not too bad for me, plus its WAY better than the FM modulator which sounds crappy when I crank it so I can hear the tunes while I ride...
I bought a LoudLiquid box from them in about 99 when I bought my first boat and liked it SOO much I bought a new one for my Epic when I bought it last year... if you have the skill/inclination to custom build a speaker platform for the top of the epic tower then I HIGHLY suggest it, otherwise I had it hanging below the tower and kept bumping my head...
happy listening...
