    Hi everyone,

    I'm looking to find an amp to replace the one that came with a Polk Audio psw303. I bought it on offerup for a few buck knowing the amp was messed up. it keeps eating my fuses and doesn't look like anything is burnt up on the board. Im not an expert at these things. Specs are below. Im looking to just replace it to get some use out of it. Maybe you guys can help me out. Replacing it with an original or getting mine fixed is just way too expensive. Much appreciation in advance.

    The PSW303 is an active subwoofer and not an AV receiver. You'd still need an AV receiver to which you'd connect the active sub and the passive speakers.

    What is it you are wanting to replace, the PSW303 sub or the AV receiver you had it connected to? What AV receiver do you have the sub connected to?

    What is your budget and where in the world are you located?

    Hi dante01,
    Thanks for the reply. I'm just trying to replace the amp that is connected to the sub. The subwoofer itself is fine. My AV receiver is fine as well. I live in Florida. Seeing that I can pick up a polk audio psw10 for under $100 I'd like to find an amp under $50 if possible.

    You've again quoted another subwoofer as opposed to an AV receiver. The cost of a PSW10 has no bearing upon the costs associated with AV receivers. You're not going to get a new AV receiver for $100 or less.

    I'm assuming that you also have 5 passive speakers as well as the active sub? It is hard to relate how much a new AV receiver will cost you because this board's membership is primarily based in the UK where models and their prices differ to those in the USA, but I can point you towards products that may meet your needs? What is it you want from the receiver and what other components do you intend using it in conjunction with?

    New entry level AV receivers typically start from about $250 in the USA.

    This is what Im trying to replace on the sub. Again, sorry for being confusing but my receiver is fine. This is the back of the psw303. So basically all I have is a box with a speaker in it and Im trying to give it some power without getting the factory amplifier.

    What you are looking for is called a plate amplifier. I'd maybe suggest you look at replacing the entire sub as opposed to just the plate amp. The plate amp is an integral part of the sub and would constitute most of the cost of such a sub. Maybe look for a used 10" 150 watt active sub with which to replace your PSW303 with?

    Anyway, here's one source for plate amps:
    Subwoofer Plate Amplifiers in the Speaker Components Department at Parts Express | 332


    and here's the actual plate amp/assembly for the Polk PSW303:

    Sounds good. Thank you dante01. I wish there was a cheaper plate amp I can throw on there but doesnt look like it. I'll even put a little car amp on there if I could. I hate seeing speakers go to waste.
