So, im going to build a fender champ 5f1, its output is 5 watts, im looking to put 2 8 inch, 8ohms jensen speakers in there (combined to total impedance of 4 ohms)
would that be possible or wont the amp have enough power to drive both the speakers
thanks in advance
As long as the secondary impedance of our output transformer matches the equivalent impedance of your speaker load your fine.

A Champ can drive 20 speakers if the impedances match up. (now I didn't say that was ideal!)
