We've only got 12 hours on the new boat and the in-boat Polk speakers produce a rattling sound. Not sure if they're blown. We've had to tuck towels between the speakers and the grills just to be able to tolerate it. Otherwise, we'd have to leave the system off. I haven't spent too much time looking at it and since the Polks I had in my 2005 SAN210 were near flawless even after adding a much higher powered amp, I'm wondering if it's a speaker problem or a a factory installation defect. Like maybe there's some screws loose. any thoughts?

Well, I spent some time today trying to figure this out. I removed the speakers and removed the grills. That stopped the rattling. Then, I reassembled the grills back onto the speakers using some 3M 5200 adhesive to stop them from rattling. That helped quite a bit, but not 100% since the tweeters rattle too. Long story short is the in-boat Polks are garbage. They literally have fallen apart. I can't believe these speakers have already taken a dump. The problem is every time a certain range of bass or kick drum gets played, they rattle like crazy. It's constant. I never turn the volume past 21 because I don't want to listen to distortion. Despite that, they've still crapped out in no time. Super disappointed. Not only that, the cheap, paper thin ABS panels they screwed the speakers into has multiple stripped mounting holes from the factory. Guess I'll need to buy new speakers with mounting reinforcement kits now. #butthurtComment

Is the amp set to hi-pass or full-pass/off? Whats the bass level set up in the head unit?Comment

Well, there are certainly far better speakers than the OEM Polks (like Wetsounds, JL Audio, etc.) and the version of Polk used as OEM is not the top-of-the-line within the Polk line up. But I have seen these same Polk speakers take some serious abuse without failure. Follow MLA's lead on the set-up. Otherwise you could have a repeat performance with an upgrade replacement product. You can re-enforce the thin plastic mounting bezels and that is definitely a worthwhile project. 3M 5200? That's a PERMANENT bond making subsequent service nearly impossible without destroying the part. Instead, use plain old 3M marine grade silicon as an above-water sealant and buffer.Comment

I'm not sure where the amp levels are set. Ill have to check that. Bass on the head unit has been set at 4 (6 is max).Originally posted by MLA View PostComment

Yeah, the Polks in my 2005 SAN were great and despite having two pairs of REV 10's on the tower, they kept up fine and I never felt a need to replace them. I just don't think they make em like they used to. I knew the 5200 was not the best, but it did fix part of the problem until the tweeters started rattling too. One other thing I realized is the only speakers that are rattling are the ones mounted in those flimsy ABS panels. The other ones mounted into the top deck are fine.

The current amp is the Polk 5000.5. I'm also planning on installing a JL free air IB sub to replace the stock Polk sub.Comment

Well, I replaced the Polks with some XS-650's. Very worthwhile. I also tuned the amps which were all screwed up. So many things weren't set right. All better for the time being until I upgrade the amps and sub.Comment
