Basskiller666 Posted January 7, 2013 Share Posted January 7, 2013 Hey there, This may be a silly question but Im wondering if I have a 4ohm quad cab and a 8ohm quad cab and my Mesa M9 has two speaker outputs is it possible to use both cabs at once? The mesa m9 has a switch on the back that is switchable to 8/4ohm or 2ohm. I havent tried to run both cabs yet, just wanted to ask the question first so I dont damage anything? Appreciate the feedback. Cheers. Quote Link to comment Share on other sites More sharing options...
LiamPodmore Posted January 7, 2013 Share Posted January 7, 2013 If you make sure the switch is at 2ohm then yes you can, although the 4ohm cab will be getting twice the power of the 8ohm cab which isn't an optimal situation. Liam Quote Link to comment Share on other sites More sharing options...
Basskiller666 Posted January 7, 2013 Author Share Posted January 7, 2013 Ok kool, I have a Fender Rumble 410 1000w 4ohm, plus a 300w Trace Elliot 1048. My M9 is 900w and using the Fender cab alone is still farting out the speakers, I am tuned to C so im wondering if its the tuning thats causing it to breakdown, it does it even at low volume:( Quote Link to comment Share on other sites More sharing options...
franzbassist Posted January 7, 2013 Share Posted January 7, 2013 (edited) At 2ohms (you'll be at 2.66) the M9 puts out 900 watts, so your cabs should ideally be rated to handle 600 watts (4 ohm) and 300 watts (8 ohm respectively).

Marvin Posted January 7, 2013 Share Posted January 7, 2013 I wouldn't know why you're Rumble cab farts out at low volume, however, the 1000w is a peak rating. Continuous they're more like 500w. But still that might not explain the problem you're having at low volume. Quote Link to comment Share on other sites More sharing options...
Basskiller666 Posted January 7, 2013 Author Share Posted January 7, 2013 Yeah tried the Trace prior to buying the 1000w fender, it was breaking down too even at low volumes and I guess at 8ohms its only recieving 450w. I have tried dropping the lows right out and it stills farts and carries on Quote Link to comment Share on other sites More sharing options...
Basskiller666 Posted January 7, 2013 Author Share Posted January 7, 2013 When I get back to the rehersal room I am going to try tuning to drop d and see if its the fact Im in C that is causing the problem, though I dont think it should matter that much, My M9 is basically brand new too so I really hope its not an amp issue, 75% of the time it sounds badass, its only on a certian few notes that it breaks down, for example just playing an open top string quite heavily it doesnt like it Quote Link to comment Share on other sites More sharing options...
Conan Posted January 7, 2013 Share Posted January 7, 2013 Sounds like there is a problem somewhere - maybe with the amp itself if both cabs are "farting" at low volume. Could it be the bass? Does it have an active circuit and if so, are the batteries fresh? Quote Link to comment Share on other sites More sharing options...

[/quote] A friend of mine just mentioned the same thing, I might try replacing the batteries next time Im in the jam room, I will also try another bass and see if I have the same problem.
