PSW505 Issues - Plate amp seems to be broken

Hi,

I had bought PSW505 from Newegg on 11/24/2014. It had been working great until I recently noticed it was creating some distortion noise. When I turn on the subwoofer, the red led turns on for a bit and then fades away with some distortion noise. It doesn't stay on.

I contacted Polk support on 12/10/2018. They said it is out of warranty and I need to buy a
plate amplifier.

Is there anything I can do to make it work again. The price of the plate amplifier quoted from Polk was expensive like buying a new subwoofer.

I will appreciate any help or suggestion you can provide.

Thank you.

    Buy a new sub.

    I feel your pain @madanthapa as we've all been through the dreaded red light heartbeat issue. Certainly a new plate amp is an easy swap out, but the price as you found out is quite high! I've swapped out a couple of plate amps on my Polk subs in the past.

    Taking your chances on a used plate amp is risky too. You may be able to find one for a deal if you're patient.

    An alternative is upgrading your sub to an SVS or others. I have a couple of SVS subs and love em! And the customer service is excellent!

    Good luck! And welcome! Keep us posted on where your journey takes you!

    Honestly 4.5 years at the price you likely paid is quite a deal! Save up and do it right this time. SVS and HSU are your best bets for budget, SQ, and longevity!
