Help a brother out... This is actually for my guitarist's(gasp) fried cab....just pretend it's for bass. He's adding four new Celestions, 30W, to his MusicMan cabinet. The speakers come in 8 OHM or 16 OHM. Based on my limited knowledge of these things, I'm assuming that 4 new speakers at 16 OHM a piece will give me a 4 OHM cabinet? Is this right? Is this ideal? Also, what would be the max acceptable wattage input from his amp? Thanks!
