The other guitarist in my band just bought a Line 6 Spider II HD75 amp. Ok, not the best of choices but my question is this, he is running it through a Crate cab. The cab is 8 ohms and his amp says 4 ohms minimum, now even though he has an amp that is 10 watts more than mine (65 watt Kustom) and is running his amp through 4 speakers and I am running my amp through one I am way WAY louder than he is. I can set my amp at 3-4 and totally drown his out while his is cranked. We are wondering if it is the ohm difference making that big of a sound difference by impeding the signal or is his head just a dud. Thanks for reading guys.
if you mismatch impedances (either higher or lower) then you'll lose power output
