    Can I use an old marshall amp of 15 watts as a head, to a custom built cabinet?

    I was also thinking, can I get just one of these things

    https://articulo.mercadolibre.cl/MLC-451727675-parlante-profesional-pasivo-600-watts-_JM

    let's say I take the speaker out (or maybe I just use the speaker as it comes from factory), put it in a wood cabinet and use the small combo as a head? ... is that possible?

    Im a total noob to amps


    greetings and love to ya'll

    If you amp has a speaker out you can connect it to another cab, but make sure the impediance match. Some amps have speaker out that’ll automatic bypass the built in speaker and other you can run in series. But first of why would you wanna move the same speaker from the combo in to a different cab assuming your Marshall is a 15w combo amp.

    Not the speaker of the amp, just using a bigger speaker, you know? like those people use for karaoke and stuff. Like, taking a big ass random speaker and use the combo as a head for it

    I can’t see why not just make sure the impediance is correct so you won’t burn the amp of blow the speaker. I’ve done it with the little vox mv50 through and old aura tone speaker.

    It might sound off as guitar amp speaker are made specifically to enhance certain frequencies for guitar whereas a karaoke speaker is made for a whole other ballgame.

    Yes and no. Yes, you can definitely convert the combo into a head. That will provide additional flexibility regarding speaker configurations and some (like me) would rather carry two smaller and lighter pieces rather than one heavy one.

    No, you can’t use a “random” speaker. I don’t know which Marshall amp you plan to convert but you need to use a speaker that has the correct impedance for your amp. In the world of random, several of the outcomes are destructive.

    Match the impedance and you should have no worries.
