    Question about replacing stereo 1996 Bayliner Avanti 3485 (Simular to 3255)-gctid803884

    Evening and Happy Easter,

    I'm going to swap out my factory stereo on my 3485 and wondered if anyone in the group has done this on a 3485 or 3255, which has the same cabin layout. Mine does not have A/C. What/where do the 12volt power leads go to the back of the stereo. Also, how do the speaker wires run through out the cabin? I'd like to run new speaker wires, but if that involves a big headache I'll leave it alone.

    I'd like to add an amp as well, though need to run heavier gauge wire for power. Didn't know if there was a factory prefabricated access to do this.

    Not my cabin, but shows where radio is located...

    On my 3450 which I assume is similar the power comes from a power bar behind the DC electrical panel. The speaker wire for the most part runs in the ceiling.

    As for running an amp on my wiring the DC panel is fed by a # 6 wire / cable. I'm running a 400 rockford fosgate 400 watt amp. It calls for a #4 cable so I had to run directly from the battery which also means I had to put some more serious fusing and shut off swithces.

    It would have been easier to run power from the panel but I had to resist the temptation as the feed was too small.

    Another option might be to run a new larger panel cable unless you chose to put the amp close to batteries. I don't know where all your equipment is located but my stereo is right next to my DC panel which is on the same side as my batteries probably 8 feet from the batteries. My cabin speakers are in the ceiling thus the wires but also the wires for the forward v-berth.speakers also run in the ceiling.

    My aft the wires run speakers in the cockpit which run in the engine compartment attached to the underside of the sole floor then up into the radar arch.

    I bet t&at 3ven with our boats differences and location differences you are going to find it similar. Your wiring is going to run toward.the electrical panel and you will.either have a bus bar to attach or just a simple breaker.

      Either way, I'm sure it will be an adventure. I'll for sure run a new power with all the bells and whistles. What I'm hoping is there is a somewhat easy path to run it with out having to do to much cabin disassemble. My fuse panel is under the starboard side, under the helm. Complete opposite of where the stereo is located. One remote chance is there was a cd changer, that has since been removed) that might have adiquite power for a small amp or at least use the wire to pull some larger wire thru.

      Another thing I'm toying with is getting a remote relay and wire up my radar arch lights to allow turning on the lights remotely. Really hate coming to the boat at night or leaving and having to turn on the lights after you are already onboard. Would make life simpler with a remote to turn them on prior and after disembarking.
