Any reason I shouldn't use my bass amp as a power amp

[gafbass02]

I've got a small mixer and I was wondering about the possibility if using it with my MoMark 800 bass head as a power amp to drive my pa.
it's a pair of pvx12 peavey speakers, we just use for vocals at pub gigs.
Doing it this way would save a lot of weight as I could leave my big peavey powered mixer amp at home.
Any reason I shouldn't?

Go from mixer to the amp's effects return, if it has one. Should be fine.

Thanks bud, Yeah, that's exactly what I'm thinking. I appreciate the amp is too powerful for the speakers, but i'll be aware of that while using it and tread carefully.

I've used my old bass head for a slave PA head. Yes, go in through the fx loop or the pre-out/post-in loop if it has one; otherwise pad the input and keep the tone controls of the bass amp neutral.

Just to clarify, would a mark bass lm250 black line work for this do we think? I don't see why not, then I'd have a spare bass head too, as I've not got one at present.

I see only one problem with this. The mixer has two outputs (stereo) and the amp only has one fx input. this will only affect the sound in the way that you'll be having your PA working in mono, appart from that you should be fine. Just keep an ear open for any signs of being feeding to much signal to the fx return socket, don't know the specs of it's maximum input signal.

Cheers mate, yeah mono should be ok. That said our laptop just died, so that could be that plan screwed!
