The bass head in question is a fender rumble 150. It may seem weird but this would work well for me, i would rewire the cab to make it 4 ohms the only thing im worried about are the speakers, will they take the low frequencies? if i dont turn it all the way up will it be okay? the cab has 4 celestion g10n 40 witch are ratted at 30 watts thank you for your time
