Santho Posted March 22, 2021 Share Posted March 22, 2021 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..?

Sent from my iPhone using Tapatalk 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.. 😅👍 Quote Link to comment Share on other sites More sharing options...

Ledlung Posted June 22, 2023 Share Posted June 22, 2023 (edited) I was just given a dead R-112SW NA. I am reading about how these sub's amplifiers go bad from overheating. I popped open the sub and saw that nearly all of the circuitry is covered with white or black goop. I guess it helps prevent loosening/damage from vibration, but wouldn't it add to the overheating problem? Are they all this way?
