A cab question.

[IndieBass182]

I have minor experience with speaker cabinets so if this is a stupid question please disregard. While looking at random cabs I came a across a 2x15 that had two inputs in the back. Would I be able to run two amps into the cab? If so, are there any precautions I should follow? This is the first I;ve seen of a dual input cabinet so running amp's into a cab stereo style is entirely new to me. Thanks for any replies I get.

I don't think its safe to plug two amps into one cab. Most cabs have two inputs so you can daisy chain another cab. In other words, the output of amp plugs into one of the inputs of the cab then the other cab connected to the first cab, as long as the amp is able to handle the combined ohms

Thank you. Like I said this was new to me. I've heard of 2 amps being used on one cab through use of outside equipment like a DI or something like that (Can't think of the name) But not through the use of 2 inputs. At least not for bass anyways.

NO.

That's a great way to put yourself in the market for 2 new amps. Imagine 2 firehoses spraying at each other at point blank range.

It's to chain along another speaker to that speaker, both being powered by one amp. Impedance comes into play too but that's the jist of it.

If you can check the model, the wiring should be described, giving you the information you need.
From what I know most cabs are wired to support daisy chaining. This means I connect the cab to the amp, and a second cab to the first cab... giving you an impedence drop!

Good luck. Try to keep the load above the minimum

NO, you can only run one amp into the cabinet. The two inputs are wired together in parallel so either one can be use as the cab input while the other one can be used simultaneously as an output for daisy chaining cabinets (they’re input/outputs).

You might encounter Peavey and some other cabinets that are made for biamping, that have separate high and low inputs for different speakers, along with a full range input for all the speakers. Also you can get stereo cabinets that can take two inputs. doesn't sound like this is either of those, but they exist so its good to be aware of them.

Thank you very much. Also to ther others I appreciate your immediate concern and quick responses. I'm glad to have such a knowledgeable community to talk to about these things.

Stereo and bi-amp capable cabs should be labeled as such.

Always check what it says on the cab, but beware: when buying used gear sometimes the jackplate is all messed-up, painted over, replaced, or unreadable. Or the cab may have been modified by a previous owner. It pays to have a tech open it up and go over the entire circuit, then label it if needed, and explain it to you.
