I recently got a Hartke 4X10 XL speaker cabinet thats 240 watts at 8 ohms. I eventualy want to get another cabinet, the Hartke 115 XL. My amp head has 2 output plugs for speakers, and the cabinet I have now has 2 input plugs but no outpug plugs. If I ever get the second cab, how would i go about making the speakers be serial wiried so taht the impedance drops to 4 ohms. Thanks

It's all the same. The input plugs are output plugs as well.

If you add a second cab that is also 8 ohms, the total nominal impedance will be 4 ohms. You've got 2 ways to wire it up which both result in the same 4 ohm load: 1)You can plug the second cab into the 2nd output on the amp, or 2) plug the second cab into the first cab.

If you plug the second cab into the first cab, won't it be a serial connection leading to 16 ohms load?? I know I'm wrong so please correct me :)

No, that's still parallel and 4 ohms. You can't wire seperate cabs in series unless you make up special cables. It's enough of a hassle that no-one bothers with it nowadays.

If you deem it's really necessary, let me know and I'll talk you through it.
