300 watt acoustic solid state head into 100 watt sunn cab with pedals

Is your cabinet 4 ohms or 8 ohms?

 

What’s the ohm rating on the cab?

 

A 2x15 bass cab thats only rated at 100w??? That just sounds bizarre!

 

That’s why I asked, there are some bass looking guitar cabs…

 

I have a 1970s B25B 2x15 cabinet that was meant to be matched with a 55-watt B25B Amplifier. I thought I read somewhere that the speakers were rated at 65 watts.

I used mine powered by my 100 watt V4B for years playing communiy halls and clubs and other places. There is a bit of speaker rattle in there now.

some past info: Difference between Ampeg B25 and B25B cabinets?

 

Should be no problem. Crank it up!

 

300 watt amp with a 100 watt cab? Better use a ton of common sense and your ears there bud.

 

That's one of the cabinets that used "guitar oriented" speakers. I would be very careful.

 

Not even close. 15s have been common guitar speakers for 60+ years.

Read and understand what @agedhorse tells you. He designs amps and cabs.

Personally, I would use a lower powered head with that cab if I liked its sound.

 

Yes, based on the guitar amp series. It was common to use 15" guitar speakers at that time, which is why they are so power limited. Fine for a 100 watt bass amp, but not so fine for a larger amp... which is what you are asking.

 

lol, if you want to run a mismatch, that is what makes it safe...
What other answer were you expecting? When the manufacturer said it was a 100w cab they really meant it was a 300w one?
