Peavey combo 300 with a power amp?

If you used a power amp that was stronger than the poweramp section of your combo yes you'd have more watts.....which would solve nothing. The power amp section in the combo is more than enough to drive that speaker. If you want to be louder you need anothe cabinet. Then you may run into other (headroom) issues and want to use a power amp on the other cab. You may just need a more powerful rig, maybe you don't.....I don't know what your band situation is, but adding a power amp won't do much for volume in your case. Just my opinion, please correct me if im wrong

You seriously don't want to run more wattage into your existing speaker cab. You can use your combo as a preamp, feeding a power amp, which then connects to a speaker cab ideally matched to the power of the power amp. Different people have different ideas about how to ideally match an amp to a cab, but the one thing I can guarantee is you cannot just add a power amp to your combo and get anything better than a blown speaker -and maybe worse.
Nope-
First, the jack labeled "Power Amp Input" is an input to the internal 300 WRMS @ 2 ohm power amp in the combo. The pre-amp out jack however, could be hooked up to another power amp, and that second amp could drive more speakers. However, the Combo 300 is actually running at 4 ohms with the stock internal speaker so the amp is only putting out 210 WRMS. Get another four ohm speaker cabinet and hook it up to your overweight behemoth. You'll get a much louder amp that way for two reasons.
First, your amp wil the be putting out about 50% more power. Second, and more importantly you'll be moving a lot more air.

I used a Combo 300 for years - the best move I ever made was getting a cheap Hartke transporter 410 cab and adding it on ( I also used a 2-10 at a different time ) - more power, more air moved, smaller speakers raised up to hear better - win win win.
The "power amp in" does not mean you run a power amp into that hole - it is the input to the power amp section of your combo amp. If you wanted to bypass the eq and preamp of the combo 300, you could run your bass into another preamp and run the output of the preamp into the power amp of the combo 300, so you would basically have "Other preamp"/ "Poweramp of C300"/ "Speaker of C300" (and any extension cab if you choose to use one).

Off subject abit but I too had one for many years. What I did was disconnect the internal connection from the amp to the speaker and add a 1/4" jack to the back of the cabinet. Then I'd plug the amp speaker out into that jack. I think the amp had 2 speaker outs. Anyway what this did was give me a backup power amp for stage. I remember on one occasion the PA amp blew and I used this power amp for the mains for the gig. Forget what I used for bass that night. Anyway I felt better always knowing my bass amp could be a spare power amp as well.

I put a 15" BW.4ohm, into a Peavey115 cab, and plugged into the external cab jack on the back of my Combo 300, and inside, it brings it to 2ohm( 300w) otherwise its @ 4ohm ( 210w).not sure how or why..but it's Very loud.. looks greatI run a 300 watt 15 inch combo with a 410 extension cab and it's all you need, volume is never above 6 even in a big venue. As posted, you're moving more air as opposed to making the existing speaker work harder through a power amp.
