I’d first sort out the battery switch habit before throwing money at it. Sitting in the cove on “All” is basically inviting both batteries to go down together, so “2” or “house” while parked and saving “1” for starting is the move, assuming MB wired it that way on yours. For the Raptor side, I’d stick with whatever meets or exceeds the engine manufacturer’s CCA requirement, so if it calls for 800 minimum I wouldn’t gamble on a 750 just because it’s close. For the stereo bank, AGM with more reserve capacity is usually more useful than chasing CCA. Also worth checking that the dealer didn’t leave you with marginal batteries from day one.

Figured it out. MB left the wires prep’d for future connections under the helm. Just had to dig in and find them. Unfortunately the reversible pump does not run with this existing switch. Verified by hooking straight to the battery with Wakemakers provided rocker switch. MB toggle switch is a SPDT and I need a DPDT toggle switch. Purchased the correct switch and will wire up accordingly.

Went out to the lake the other day and magically the speaker is working. Hoping that by yanking on the wires and redoing the connections it fixed the issue.

2024 23 foot alpha. 4 tower speakers, factory stereo. Floated in the cove this weekend for about 3.5 hours with switch on "All" and it was dead. Was thinking of switching to AGM batteries but the ones I put in my last MB apparently aren't sufficient for hte Raptor? (Duracell AGM at Sam's with 750 CCA). Looks like hte Raptor requires a minimum of 800. Wondering what people use. Also would like a bigger battery to run the stereo (and will keep the switch on "2" once I confirm the stereo wiring goes to the "2" battery).

Hey all, 2020 MB Tomcat F22 - Full original Exile Audio system. Starboard side bow speaker does not work at all. All other cabin speakers work. I swapped the speaker to the other side and confirmed the speaker does work, just not that location/channel. Amp is Exile Javelin 5. Is it possible that this one channel is dead? Pic below (red and black wire). Anything else to look out for or consider? I’ve swapped RCA cables and rechecked connections. Thanks! -Duke
