Hello all. I did a thread search and read all the stickys and now I think I know less about my problem than when I started. I have 2 cabs. a hartke 210 & 115. both 8 ohms. The amp has 2 outputs, a 2ohm min and 4 ohm min. which output should I use to daisychain the cabs? Does it matter? Also could I connect 1 cab to each of them? Lastly, which output should I use if I only want to connect 1 cab? Its a Peavey tube head if that makes a difference. Thanks in advance.

A. The two cabinets together will be a 4-ohm load. That's because whether you daisy-chain them or not, the ELECTRICAL connection is parallel, and two 8 ohm loads in parallel is 4 ohms.

B. Use the 4 ohm tap on the amp. If it only has one jack lableled for 4 ohms (can you post a photo of the back of the amp? And maybe list the exact model name/number?), then daisy chain the two cabinets together from the 4-ohm jack.

C. If you only use one, you SHOULD be OK with again plugging into the 4 ohm jack. Not knowing which amp it is, or how old it is, I can't be sure.

Although running one 8 ohm cab with that head won't instantly kill it, prolonged use may very well. To be safe, it would be better to always run either a 2 or 4 ohm load. The amps output transformer likes a matching load to it's design, in this case, 2 or 4, just like an SVT.

BTW, the owners' manual (it's available on-line at Peavey's web site- look for archived manuals) says you can run two 4 ohm loads by plugging one into each of the speaker jacks. And reading the manual, it only talks about 2 ohm and 4 ohm loads.

Safest thing is to run both cabinets daisy-chained from the 4 ohm tap.
