2015 G boat stereo questions

[tommy1005]

atleast they didn't run the bow off the head unit......that's easy to switch around those wires, then bridge the 4000.4 to the towers if you swap to Wetsounds up there....400 per channel is about perfect on any of the wetsounds tower speakers.

Yeah my '05 210 had the bow off the head unit... It was worthless.
Tommy- how exactly are you running the 2 bow, 4 cabin, and sub on the 5000.5?

[tommy1005]

2 bow speakers off channels 1&2, 4 cabin on channel 3&4, then channel 5 to the sub.....from the 5000.5 that should give you 70 watts to each of the bow speakers, 50 watts to each of the cockpit speakers, and then I can't remember if the sub is DVC or not, if it's not that's 200 to the sub, if it is DVC then 400 to the sub.

Honestly the best option if you have 2 factory tower speakers would be to bridge channels 1&2 and 3&4 on the 5000.5 to the tower, then run the bow speakers off ch 1&2 and the cockpit of 3&4 on the 4000.4. This would give you 125 to each of the bow speakers, 100 to each of the cockpit speakers, and 200 to the tower. I'm all about having free power and if you have the amps there you might as well use them to the best of their abilities. Wiring it this way you would pick up a little power for the in boat speakers and almost double the power going to the tower.

You would want to run the 4 cockpit speakers in parallel to get the amp to see a 2-ohm load, so running the left on channel 3 and right on channel 4 straight from the amp is the easiest way to accomplish that. Since the wires are already at the amps, it's just a matter of unhooking them from one output and hooking them into the other.

That's all assuming that the speakers are all 4 ohm, and that he doesn't have Polk's rated at 3 ohm which are actually closer to 2.7 (they round up). If that's the case the load drops below what the amplifier is rated for, if you pull one out you can see what its rated for. My 2012 has the MM651um's that are rated at 3ohms which 2 in parallel is actually closer to 1 than 2 ohms (1.35).

[tommy1005]

The MM651's are 2.7 ohm and the MM651UM's are 4 ohm speakers according to Polk......however, Polk can't tell me which speakers Nautique uses in their boats. If they are the 2.7 ohm variety, then you would absolutely need to run each speaker on their own channel.

I had to deal with Polk for replacement of one of mine under warranty, it took a couple of tries to get it close to right. Mine are the black with black frame MM651UM's and they are clearly marked as 3 ohm and replacements they sent are clearly marked as 4 ohm (took a while to get the right color scheme). It confused even the people at Polk but eventually I think they decided that they specifically made those for Nautique although they weren't sure if they were really 2.7 or if they were just labeled that way, I do know they had to get the black frame ones from the east coast because they didn't have them in the west coast warehouse.

I think there are several variations out there so just make sure of what you have. You could always measure them, as a basic test you could use a multimeter set to DC resistance and measure a speaker directly with the wires removed. For a 4 ohm speaker measured this way it should be somewhere above 3 ohms and an 8 ohm speaker measures about 6. If its truly a 2.7 ohm speaker it should be somewhere less than that. While thats not a true measurement of impedance which is resistance to alternating current (and it varies based on frequency) it gives you an easy way to estimate.

I think this is a moot point though since I am pretty sure the G's don't use the MM651UM's but it wouldn't hurt to double check the rating, especially for those of us with them.

Whitetail; sorry, I didn't mean to hack your post.
When my local nautiques dealer replaced my bad 6.5's they put in wet sounds so I've got no idea what kind of Frankenstein speaker set up is in there currently- I mean I can tell you what brand of speaker is where and where each speaker's wires plug into what amp, but ohms and model #'s are way above my stereo knowledge.
