help with wiring

Post by carl300367 » Thu Oct 17, 2013 7:51 am

i have just bought a blackstar 4 x 8 cab to put my ht 1 r through as on the back it has an output for an external cab .

I also would like to put my peavey vyper through it at some point but this doesn't have an output for a cab but it does have a headphone socket, i've tried that and it doesnt work well.

what i was thinking was tapping the speaker cables on the peavey and joining them to a guitar cable .

Q- would the pos for the speaker go on the centre core and the neg to the sheilding ?

Don't use a shielded instrument cable for speakers. The shielding wire is inadequate for the power from an amplifier. You'd be better off using some 2-core insulated mains cable, like the stuff used for lighting (5-10 amps rating). Positive to tip of jack plug and negative to sleeve.
