I have an old Carvin PB 300 head that I've had going into an old KMD 4x10 8 ohm cab for quite a while with no problems. The amp has been great. The Carvin rates at 150 watts at 8ohms, 200 watts at 4ohms, and the full 300 watts at 2ohms. I recently bought a 2x10 Avatar cab rated at 4ohms. According to Dave at Avatar, I'm getting like 2.7 (or something like this) ohm rating when I run both cabs together which is supposed to be safe for my Carvin amp. So I should be getting close to the full 300 watts with this set up. Eventually I plan to lose the crappy old KMD cab and buy a 2x12 Avatar rated at 4ohms so I can finally get the full 300 watts from my Carvin. Problem: When I play with both cabs hooked up, the Carvin sometimes shuts down on me in the middle of my gigs! This seems to happen whenever I crank the volume on my bass or when I really dig into the strings (which I do a lot). To fix this I reset the amp by quickly turning off the amp, then turn it back on, then I back off the volume knob on my bass and keep playing. Needless to say, this is not too cool in a live situation. What am I doing wrong? I basically have the Avatar going into one speaker jack and the KMD going into the other. It appears this is working the amp too hard and to protect itself, the Carvin shuts down the speakers. Sooooooooo, I thought I'd try daisy chaining the cabs. I could have the Carvin go into my Avatar 2x10 then have the Avatar go into the KMD 4x10. I can't really try this at full volume for another 2 weeks at the next band rehearsal (I don't dare attempt this at my apartment with my landlady living right over me!). Do you think daisy chaining will fix the problem? Why the heck am I having problems to begin with? I want to buy another 4ohm cab but Im nervous that Ill continue to have this problem. Help! Anybody!!! Thanks, r PS for the record, the Avatar cab is awesome.
