I've got what I'm sure some will think is a really stupid question but I'm at my wits end trying to find something of any substance on the internet. I have a Spider IV HD 150 which we probably all know is stereo at 8 ohms per channel. I'm looking at getting a new cab that is rated at 8 ohms mono, 4 ohms stereo. As I understand it, it's generally a bad idea to run a single channel since the amp is designed to run stereo; makes sense. As I also understand it, while it is generally ok to run an amp with a lower impedance to a cab with a higher impedance (e.g. 8 ohm amp to 16 ohm cab), it is not good to run it the other way around (e.g. higher impedance to lower impedance).
So, after doing some looking it seems that one option is to simply rewire the speakers into to 16 ohm series, deal with a little volume loss, and you're golden. However, I was wondering if it's possible to bridge the two stereo channels by way of a y adapter. It seems, in my incredibly limited knowledge of the subject, that in theory you would be left with a 4 ohm mono out that could be fed to a 8 ohm mono connection on the cab. This almost seems too simple but it make sense to me, again with my limited knowledge on the subject. Thoughts? Suggestions?
Thanks. - James
