    Thanks to all that I’ve learned about stereos by following all the experts on this site, I’m thinking about a series upgrade to my stereo.

    Before I get into what I’m thinking of changing, here’s what’s in the boat currently (all factory installed):
    - Polk DB651’s in the bow and rear cabin
    - Polk db521’s on the swim deck
    - WS Stealth 10 soundbar
    - Polk MM1040UM sub
    - Polk 5 channel amp, PAD5000.5, 70w x 4, 200w x 1 RMS @ 4 ohms
    - bow and rear cabin speakers are wired in series; same thing for the soundbar and swim deck speakers

    Here’s what I’m thinking of doing:

    1. Add a pair of front cabin speakers, ideally db651’s. I’d like to mount them high like several others have done. Not sure I can do that given the offset shape of the black liner (pics included). Maybe I can mount a smaller speaker like a 5.25 in. Which begs the question, am I better to do this or mount the 651’s down low

    2. Change the swim deck speakers to db651’s. I think they’ll fit

    3. Change the sub to a JL M10IB5. Should I consider the JL MX sub or maybe a WS IB sub?

    4. Wire the bow and front cabin speakers in parallel. Do the same with the rear cabin and swim deck speakers

    5. Use the polk amp to power the sub and bridge the other 4 channels to power the soundbar. The recommended power is 150 w per channel and the bridged amp is 200 w per channel. Is this too much power?

    6. Last but not least, add a 4 channel amp to power the other speakers. I was thinking about 200w per channel at 2 ohms which means that each speaker should get about 100w. The Polks are rated at 60w RMS and 180w maximum. Does this seem like the right power?

    7. For the amp I’d like to add, the choices I’m considering are the Polk 4000.4 (200w x 4 @ 2 ohms), the WS Syn dx4 (same power) and the Fusion MS-SG41400 (220w per channel). But the Polk is 1/3 the price of the WS and half the price of the Fusion so I’m leaning it’s way. Should I consider other options or other amp combinations?

    Appreciate any advice. Many Thanks.

    You sure got a lot going on there. 9 total speakers being ran off of a 5 channel amp, crazy.

    Here is what I would do: I would buy the polk 4000.4 amp and wire up a speaker per channel and see how it sounds. The front cabin, rear cabin, and sub to the 5000.5. Tune the amp to the appropriate wattage. Put the sound bar to the 2 channels of the 4000.4 to 125watts, and put the rear swim deck speakers to 60 watts to which ever speakers you decide. That would be phase one. From there after I have everything powered that way I wanted it I would then make choices if I wanted to upgrade equipment or added speakers. Putting that sound bar on its own channel and having full power makes a HUGE difference. I would at minimum replace the sub with a JL or wetsounds true IB sub.

    Thanks. What would you do with the bow speakers?

    With the way that Yamaha has wired 9 speakers into a 5 channel amp I would say that they are wired in series making the amp see 8 ohm and that will drastically reduce what the amp puts out power wise. Once you have each speaker on its own channel supplying the correct RMS wattage, I think you will be surprised a little bit. Before cutting any new holes, wire it up with both amps and then you can start adding additional sound if necessary.

    I just did this - and it makes a huge difference. Best $60 mod yet.
    I also second what @jcyamaharider is saying. I added a Polk 2000.2 to run my sound bar @125 watts rms per channel (and soon some JL MX650's on the rear platform in parallel 2 ohm 200 watts per channel). This gave the bow and cabin speakers all their own channel. Much more mid-base and clarity now. Really woke up the Polk db651's.

    I'm contemplating re-purposing the Polk db521's from the swim deck as helm speakers - but unsure if I would just add them in parallel with the rear cabin speakers (should be 2 ohm then).

    Thx guys. Great suggestions. And yes mine are wired in series.

    Geohill (sorry can’t figure out how to do the @ thing), did you end up rewiring all the speakers to put them on their own channel?

    And when you say you did what swatski suggested, are you talking about adding a 2nd sub or rewiring in parallel?

    Thx again.

    I ended up running mostly new wire - I used as much of existing as a thought possible but the series wiring meant a lot of cutting. Apparently I'll be re-wiring again too as I used copper strand wire...which I guess is prone to corrosion.

    I did add a second sub on the port side and just wired it right in in parallel. Works great. Had to adjust the gain a bit but the increase in low bass is incredible.

    Thx. Where did you put the 2nd sub? And what kind did you get?

    I’m thinking I should just run new wiring everywhere. Just as easy to pull two wires per speaker as one. Thoughts?

    I did the same Polk db1040 in the same location on the port side as the oem one on the starboard.
    I’ll be running all new wire soon too.
    Here is me installing the grill

    Good stuff. Thx.

    What kind of wire are you running? I understand oxygen-free is the way to go? 14 gauge?

    I used some car audio stuff I had sitting around - so I’ll have to re-do it.

    Let me know what wire you decide to use. Sounds like a good winter project for both of us.

    I'm on the fence - I'm leaning towards this: http://a.co/18UJFDm
    but I know the wet sounds WW series is better....just really expensive. Fully tinned at least.
