I have a R-112SW, it has been working fine until a while ago..  it has started turning off randomly. Sometimes it can stay on for hours, but sometimes it turns of after seconds of use.... So I figured I'd just change the plate amp, but I think I might need some help picking the right amp...

 

My the sub is rated with 300w RMS with 600W peak if I'm not mistaken..? So what wattage for the amp am I looking at then...? I've found 2 different plate amps from Dayton Audio which as far as I can see will fit perfectly without any modification to the sub box itself atleast... 

The Dayton Audio SPA250DSP, the other one is primarily the same amp just with 500w (SPA500DSP)

 

So my question is which one of these amps will work the best..?

I have a R-112sw and have the Dayton 250dsp plate amp installed in it, I feel that it’s very under powered for it, I would go with the 500 amp if I knew just how weak the 250 is.

Hmmm.. okay thx for the input dude! I just bought a Dali e-9f so I'd atleast have some subwoofer while I fixed my Klipsch sub. But considering the price for the dsp500 I might just go for buying a second e-9f then, because one 9" isn't really enough... Hopefully the Dali subs last more than 4 years.. 😅👍

300$ a piece -------I am 100% positive that a good tech can repair the amp for around 100$ -------the issue could simply be a couple of capacitors and 1 hour of labor ,

Most of the time it’s the power supply caps that have gone bad

KLIPSCH should have an exchange service for all their subwoofers amplifiers   /you send your old amp , they send you a refurbished amp -  1 year warranty -- 1 flat fee -

I don't see that happening.
