    Default 6505 quad

    So I've just picked up a 6505 quad- it has a canon jack and an xlr jack on the back- it doesn't say what ohmage to run it at though!
    So that's question number one-
    Question two is- can I re wire the box so that each one of these inputs can run at 8ohms at the same time. So two speakers are wired to one output at 8ohms and the other two are the same?
    Im trying to get it to do the same job as a marshall stereo quad.
    The idea being that I run the 6505 head into one input and the 'wet' amp into the other input.
    Does that make sense?
    I used to be 'sean112' but lost all my details!

    I'm a little confused overall what you have. Can you post some pictures?

    No camera- sorry. Im basically trying to turn a quad box into two two by 12s.
    So two of the speakers in the box are powered at 8ohms and the other two are powered by 8ohms as well- sort of turning the box into stereo but with 8ohm inputs for each set of two speakers.
    One input jack driving two speakers at 8ohms and the second input jack driving the other two speakers at 8ohms.

    Best way to explain it is Im trying to turn a 16ohm box with one in put driving four speakers into a box with two inputs that are 8ohms each driving two speakers each- as far as I know the speakers inside are all 16ohms.

    OHHHHH! It's a 4x12 cabinet!

    From the spec sheet on the Peavey site what you want is how it's wired from the factory. Sounds like the one you have is modified.

    No- the newer cabs have a stereo option- so you can run it at 4ohms or 16ohms in mono or 8ohms in stereo- the older cabs only had one input- 16ohms BUT they had a canon jack in or an xlr (same as a microphone plug) in- you used one or the other but either way they were 16ohms. What Im trying to do is convert it to the newer style.
    It has four 16ohm speakers and I want to run two of them to one 8ohm input and the other two to another 8ohm input, So Im splitting the cab in half- two speakers run at 8ohms and the other two at 8 as well- seperate from ecah other- but in the same cab.

    OK, so I've looked into it and yeah, the older cabs were only mono at 16ohm with 1/4" input and XLR input. Definitely a weird setup.

    So, basically, what you have in there are 4 16ohm speakers. They're wired in two parallel pairs, which gives you 8 ohms each side. When you're using the cabinet in mono mode, those two pairs are wired in series with each other for 16 ohms total load.

    What you'll need to do is get something like this.

    Cut a square hole in the back of the cabinet, mount that, and wire it up. Doesn't necessarilly have to be that one. I just linked to that to give you an idea of what you need.

    Thanks mate- so here's what Im thinking of doing- wire two of the four speakers in parallel this should reduce the ohmage to 8 ohms and connecting them to one of the input jacks on the back of the box (the xlr one for example).
    Then wire the other two speakers the same way (8ohms) and connect them to the other input jack (the canon one).
    I think this should work so long as both jacks are completely separate from each other to avoid shorts from using a common metal plate.
    Should also avoid having to cut holes in the cab if I ever want to change back?
    What do you think?

    It should work. I'd also replace the XLR jack with a 1/4" jack (what you call a cannon jack). It just doesn't give you the option to run it as a single 16 ohm cab. However, if you want to run one 5150/6505 head on it, use both output jacks on the head to connect to each side and set the amp to 4ohm (the jacks on the head are wired in parallel).
