My new amp (60w Fender Super-Sonic head)has a selectable ohm rating on the back, 4,8 and 16 ohms. I have a handmade cabinet with two 8 ohm celestion V30 speakers in it. Right now I have it wired in series which would make it a 16 ohm cabinet, but if I wire it in parallel it will be 4 ohms. Does anybody have some advice on which is the best way to go? I see a lot of amps have an 8 ohm rating, is that best? Thanks.
