That is exceedingly bass heavy, and yes it will stress your woofer greatly. Better to set your bass at noon with no boost or cut and then go into negative EQ and start subtracting treble; high mids, and low mids in that order until you arrive at the desired depth.

I like a lotta bottom end but I've found on both my R40 and R200C I have to run bass at 10-11 in most situations. I do use "vintage" most of the time. Gain no higher than 9, volume 12 or so depending on the room. I normally don't use the o/d. For example, I'm with a big band Wednesday night-o/d Definitely off.

Hello All - new to the forum here... just purchased an old (v1) rumble 100 1x15 (didn't want to spend more than I had to, because I'm saving for something bigger - considering the rumble 500)

Anyway I've got what is quite possibly a dumb question... on the back of the unit are two connectors marked + and - What is the purpose for these? (thinking to connect another cab maybe , but wouldn't a 100 watt amp struggle a bit for that?) any help is welcome :)

and don't forget to take it outside for a test run. Turn the damn thing up good and loud too. Often times it's the house rattling and not the amp.

Yes. It can be deceiving. I had a 25 that was rattling like crazy. I thought it had blown, so I bought another one. Then I plugged in the old one in a different location and it is fine. There was something it was resonating with causing the noise.

Doesn't matter provided you can come up with the original receipt. Maybe the seller you got it from has it.
One more thing, play it with a headset. When you plug into the headset jack, it defeats the speaker. That will tell you if it is the amp or not. And, move it to a different place in the house. You could be getting resonance from some place in the room.

Welcome Rumbler #969! I can't help you with the v1 question. I know nothing about them. you might check the Fender Rumble Club Wiki Pages or @Linnin is our resident expert on all things Rumble. As to the 500:

Thank you,I play it at Church,and I am going to check the settings,and I will check it by plugging a headset in and listen. I have it off the floor,and on an amp stand. Will give an update later. Appreciate all the comments,and advice.

The amp stand is a good idea, but there may be something in the room vibrating with with the speaker. That is what I meant by resonance. If you know this already, great. Don't mean to insult you intelligence, but I don't know your background, so I don't know what you know about sound. Hope it works out for you. But, as @Linnin said, you can replace the speaker.

That's not factory. Something a previous owner installed. Can you post a photo? https://www.fmicassets.com/Damroot/Original/10001/OM_leg_bassamp_Rumble_100_2X10_&_1X15.pdf

They look like speaker connectors.

They are after market screw terminals to hook up an extension speaker cabinet. Very weird choice to use that type. I would pull the grill and your woofer and check it out to see if it is original and what is the ohms rating that should be printed on it somewhere. The stock 15 is a 4 ohm woofer, and you should not go below 4 ohms without doing some serious damage to the power section. Find a friend that knows something about electronic circuitry and check how this is all wired up. I would disconnect those terminals for safety reasons if nothing else. They are hot anytime the amp is on and as such they are dangerous! Cover the whole panel with a black duct tape.

I prefer the international orange duct tape; otherwise, you could trip over it in the dark.

The 15" woofer in my 200c is 8 ohms I think. Is it different from the 100c?
