Yamaha SX210 amp and speaker install

[@valkyrie6926]

You did a fantastic job, everything looks great, very neat! Very detailed video! Loved it! 👍

[@gandl2123]

Interesting. My 2011 SX210 does not have the access door on the steering side. I guess I have to lay on my back and crawl under the driver area. Problem? Battery was out when I go the boat and wires everywhere...hooked all black to neg and red to positive and something blue a fuse. So...not even sure how to hook up all the wires that are near the battery. Any help would be appreciated.

I would take your questions to jetboaters.net Also, any pictures you might have to help show what your dealing with could be shared there.

Great job - I've been looking for this type of video! Did you consider adding a fuse panel for the system? Not sure of the pro/cons

[@oramac9]

No, everything is already separately fused. But, I am contemplating bus bars for my positive and negative connections so I don't have so much wired directly to the batteries or the battery switch.

[@brookefore4618]

If you wired amp power directly to the house battery, how is it fused?

[@oramac9]

There is an inline fuse in the 4 gauge wire. It comes in the Rockville kit.

[@JonathanChapman-q5h]

Hi - great video. V useful. Thanks. On wiring kit; I noticed you did not put supplied fuse on live wire? Is it not needed? Thanks

[@oramac9]

I did install the supplied fuse, it's just not pictured.

[@JonathanChapman-q5h]

Thanks for the reply.

[@gonzchi]

Great video! I have the exact same boat. What about the second battery? Did you install a voltage relay to charge it while underway? Like the Blue Sea Add-a-Battery kit ?

[@oramac9]

I just added a basic two battery switch.

Great video. How much play was in the speaker cutout? The infinity specs say they need 5 1/16”. I’m wondering if I could use speakers that require 5 1/4”. I don’t want to do any cutting on the fiberglass.

[@oramac9]

I didn't measure the existing holes. The infinity speakers fit pretty spot on. There wasn't much play, but the speakers weren't 'tight' either.

[@indianacountry5352]

I like that little boat! I'm just south of Indy. Where did you buy it and about what was the out the door price?

[@oramac9]

Bought it new at Just Add Water boats on the east side. $51k after taxes and fees

@@oramac9 I have a 2020 SX210. Ordered mine in October of 2019 before covid hit. Paid 43K OTD which included a 3 year YES warranty and a Yamaha cover in Lake Havasu, AZ.

[@luistejada1058]

Did you re-connect the original harness back together after cutting it to use the speaker wires? I see there are still a red and black wire still there.

[@oramac9]

Yes. The power wires are the only things still going to the head unit.

[@luistejada1058]

@@oramac9 Thank you!

[@benjopat]

Did you pre drill the new screw holes

[@oramac9]

Absolutely.

[@FALCON_619]

Did the stock speaker wiring work out ok, or did you find that you needed to upgrade it after? Thanks.

[@oramac9]

I used it all season, and it never let me down. I believe the stock wiring is more than adequate.

[@FALCON_619]

@@oramac9 perfect! Thanks!

[@cmason5203]

Good video

[@blad1978stavro]

Thanks for details explanation... Appreciated

[@oramac9]

Happy to help!

[@benjopat]

How much extra did u have on your power and ground, I have a ar240 wondering if the 18 feet will work, thanks

[@oramac9]

I only had 1' of positive cable left over. Not sure what kind of access you have through your fuel tank access hatch, but a more direct route from the batteries would have given me much more slack.

[@benjopat]

@@oramac9 thanks for the input, I got one 20’ hope it makes it, Im going with the same infinity’s and gonna try a kicker 10” tube

[@benjopat]

So is it a huge difference, and would you tell a difference without the amp just the speaker change

[@oramac9]

The quality of the sound might improve, but the head unit only puts out 20 watts, so the volume still wouldn't be enough to overcome engine noise at speed.

[@oramac9]

I can now hear the stereo easily at any speed.

[@socalifone3044]

I swapped mine out also I tried the speakers only. It SUCKED Added amp. Now sounds great

[@KFowl35]

3 months later - anything you’d change with your system?

[@oramac9]

Not at all. The sound is excellent inside the boat. The only change down the road might be adding some rear deck speakers.

[@brookefore4618]

How are the stock speaker wires holding up?

[@oramac9]

No issues. They handle the power just fine so far. In fact, I had to adjust the gain down on the amplifier, because it was painfully loud on the boat. Clean, but LOUD. I couldn't turn the head unit up beyond 50% before the volume was unbearable. Yes, the wiring is fine.
