    NO

    not at the same time. you'll destroy your heads (at least the lower wattage one).

    now if you want to switch between the two without switching the cable you'd need to have a special switch made for you that could handle speaker level current and that has a "break before make" type switch on it. the real techs know more about this than i do.

    Not at the same time, but tonebone makes a switcher that lets use switch heads in a pedal form. It's not cheap but it does the trick.

    Even if it would work to have two amps into one cab that wouldn't be stereo anyway.
     
  8. Rewire your cab so it has 2 seperate inputs and stuff, basically make it two 2x10's in the same box

    That would change the impedance of each "cab", but would make it stereo

    Someone please word that better before this guy explodes himself

    Radial makes a box that will switch between 2 heads and one cabinet. Thats one head at a time, though. I used to think something like that was technically impossible but those guys at Radial have all sorts of clever boxes these days. Not cheap tho'

    dont worry i had an electrical engineer help me and he said that i have to "split the cab" but because of teh speakers in teh same box it would sound bad, so im just going to have to buy me 2 cabs

    OR...he can feed the preamp out (effects out) to the other head, then feed it into the active in of the other head. That would be louder, but not resault in a stereo rig. Neither would putting them into the same cab either. Or, as someone else said, you could wire the speakers but as far as I can tell, you are too inexperienced to perform this (no offense). Try and take the cab to a car stereo place or even your local music shop and tell them what you want to do.

    actually i did the subs in my car and i already have a 4x10 cab made out of old car subs thats 8ohms but i hate the sound, and i did all of that stuff with just a little bit of help from some level headed on this website and the wiring diagrams on avatars website, my uncle and dad does custom car steroes so i have been around this stuff sence i was little. and im in pre-cal and still a jr in highschool so ohms and stuff is just basic math. i wanted the stereo 4x10 cab only for portablity, but i CAN wire it up to 2x10s but how the cabs are made theres no way to divide the 2x10s up. also what makes you think that im "too inexperienced to perform this" im j/w. but if some one older than me tells me that and explains why then ill consider to trash my ideas but until then i KNOW i can.

    I'm just guessing, but it is probably just a cautious thought based on the original question (regarding two amps into one cab). I don't think it was at all derogatory, just someone making sure that no one gets in over their head. No one here would want you diving into your cabinet and ending up with something you couldn't get to work. It would be better to assume that you didn't know how to rewire it (when you actually could do it), than to assume you know how to do it (and you really didn't).

    What are you trying to achieve with a stereo setup? Are you going for a biamp setup? Did you want a 'clean' amp and an 'effected' amp? Two different amps, one driving each channel? Is there a specific player's sound or style you're trying to get? Are you just wanting to try something different?

    I'm just asking because many (including myself) have tried stereo and/or biamp rigs, and found them to be less than the sum of their parts (meaning running the same amp and cabs in mono sounded better). One unique example I can think of is Amy from the band Clatter. She has a lot going on with her Ric and multiple amp setup. She has done a lot of work to get her sound, and it's perfect for what she does. See Amy's equipment list here

    I personally love trying different things, but usually they take money and time to work through to completion, and often the end results are not earth-shattering.

    Honestly I think i'd be nice to do that, running a TFB550 and an SVT-CL into a berg NV425 as clean and distortion heads, respectively. GAS!!!

    Thanks, and no, I wasn't trying to offend. If you ran out and tryed to do it, and screwed it up, I'd feel pretty bad. Better safe then sorry.

    Stereo in one cab doesn't have to sound bad, the Trace BFC had the 4x10 split into a left and a right and a 1x15 sub for good measure and it sounded good, nearly bought one till I felt the weight, 87kg. Imho stereo is over rated in amps, you can do some cool stuff but it is an expensive road to go down. Anyway, I think you're best sticking with mono, if you want to go stereo, get another cab and get a signal splitter cable so you can feed both amps.
