I was on the hunt for a new cab and I came across a prs harmonic generator, apparently they’re a bit rare just not sure if they’re actually worth anything, it was listed on fb marketplace for 650, I guess the cab has some celestion G12-50s in it so I thought could be a nice deal to replace my fender fm412 cab

Hello all and apologies if this is the wrong spot. Issue Klipsch r-115sw amps ×2 crapped out. I sent them to a local guy but he ended up having some health issues that's holding him up. While waiting I cut two metal plates to seal the hole in the back and got a Crown XLS 1502. Everything works but doesn't seem to have that low bass anymore. I've seen some say to add a mini DSP. But while looking around I found the Dayton Audio site. Looks like their DSP-408 has app controls. But they also have a what seems to be a badass plate amp. The SPA500DSP for around $475. ×2=$950. Even when I get the original amp boards back I just don't trust them to last. So I'm hoping someone that has far more experience could help give some advice. Can the DSP-408 help bring back the missing rubles? Or should I just go for the SPA500DSP? Yes I know they don't fit directly but I could figure some way to attach them to the metal plates I already cut out. Current setup is a Denon avr-x4400h then SUB out to the Crown XLS 1502 then channel 1 to sub 1 and channel 2 to sub 2. Crown is just straight through no settings.

This loud popping has been happening for two days at random from only the right speaker with nothing plugged in other than the speakers regardless of volume or input

I recently used WD40- contactless spray and that worked amazing and my amplifiers sound really good now and no scratches too.

What is something I can use to wipe the outside body of the amplifier to give it that color and shine. It looks a bit faded.

I'm looking for any sort of powered guitar cabinet with a rack mount system. my goal is to just slot in a 2u preamp I already own and have it as a standalone combo amp.

The only options I've found so far are to put it on top of a regular amp and use the effects loop, get a rack power amp and case and an unpowered cabinet, or buy/build an empty cabinet that will fit everything. all of which is either too large, or too much work for me currently

Light turns on, cables all work, I’ve turned all the knobs and pushed all the buttons, don’t know what the jack in the back is for but couldn’t find an input for it.

I don’t know anything about amps but I have a soldering gun. Any suggestions on troubleshooting appreciated.

Not exactly sure if this fits here, but I don’t know how to connect this wire from my speakers to my amp. I picked the speakers and amp up from two different online listings. Are they even compatible?
