Members FinchTheory Posted March 22, 2006 Members Share Posted March 22, 2006 Wow, best day ever. I got my Mesa Boogie 4x12 today and want to crank it, but I'm confused on the ohms. I have a mesa boogie 2x12 already and I was going from the head(8 ohms) to the cab (8 ohms). What do I do with the 4x12. On the 4x12 there is two 4 ohm slots and one 8 ohm slot. What do I plug it into. Okay sorry if this is confusing, but basically what do I do for ohms when... -I want just my head and my 2x12. -I want my head and my 4x12. -I want my head and my 4x12 and 2x12 at the same time. If you guys help me out I will post pics. Link to comment Share on other sites More sharing options...

If you guys help me out I will post pics. It would help if you gave all the info needed. I assume the 8 ohm jack on the 4x12 is the mono input and the two 4 ohm slots are for stereo,correct? If so,why would you even mention them. Anyway,if the 4x12 cab is 8 ohms mono and your 2x12 cab is 8 ohms,its pretty simple. You are at 4 ohms total so either daisy-chain the cabs or use a "y". I assume you realize that each driver in the 2x12 cab will be getting 2x the power of each driver in the 4x12 cab. Link to comment Share on other sites More sharing options...
Members FinchTheory Posted March 22, 2006 Author Members Share Posted March 22, 2006 Wow that really really confused me. I believe the 4 ohms slots are stereo and the 8 ohms is mono. Do I do 8 and 8 for just the 4x12, meaning 8 ohms on the head and 8 ohms on the cab. I have to speaker cables so if that works as a daisy chain then I can do that. Idk you're kinda talking with an ohm and stereo mono noob so this is hard for me to understand. I just always though 4x12s ran at 16 ohms. Link to comment Share on other sites More sharing options...
Members potaetoes Posted March 22, 2006 Members Share Posted March 22, 2006 with one cab, use the 8-ohm output into the 8-ohm jack on the cab. same goes for either cab. with both cabs, use both 4-ohm outputs on the amp into the 8-ohm jacks on both cabs. in this case, the total load of the two 8-ohm cabs is 4-ohms, so you use the 4-ohm outputs on the amp.

Members FinchTheory Posted March 22, 2006 Author Members Share Posted March 22, 2006 Haha that made everything so much easier, thanks a lot. One last question when using both cabs is it alrgith to just use both of the speaker cables. Meaning one from the heads 4 ohm into the 4x12s 8 ohm, and the other from the heads other 4 ohm into the 2x12s 8 ohm. Wow im really excited now.

Members IcedEarthian Posted March 22, 2006 Members Share Posted March 22, 2006 can I run my trad 4x12 in stereo with my powerball? right now it's at 8ohms mono....do I just take two speakers cables and plug them in the four ohms on the head,then to the cab?
