Members Raskolnikovs axe Posted October 11, 2005 Members Posted October 11, 2005 So i'm trying to help my bassist put together a rig - a 4x10 and a head - and I just got an 8 ohm Avatar 4x10 on eBay. Question is, most of the bass heads I'm finding are 2 or 4 ohm. The Avatar has 2 inputs - is there any way to rewire or hook it up to a 4 ohm head so that it will work?

With a solid state head, the ohms rating is just a minimum. An 8 ohm cab will work fine.
Members Apendecto Posted October 11, 2005 Members Posted October 11, 2005 Bass heads with 2 or 4 ohm are usually the minimum (2 is pretty rare by the way). 8 ohms should be fine through any amp. Rewiring? I've got no idea. But I do know that if you wire it together with another 8 ohm cab you will have two cabs running at 4 ohms. Yo.
Members Raskolnikovs axe Posted October 11, 2005 Author Members Posted October 11, 2005 Will I still get enough volume out of it? I'm asking because on one head I'm looking at ( a peavey Mark VI ) it says 400 watts at 2 ohms, 250 watts at 4 ohms, so I'm assuming going up to 8 ohms would reduce the wattage even more. We're a fairly loud rock band so a decent amount of volume will be needed. Thanks for the help!
Members Gruven Posted October 11, 2005 Members Posted October 11, 2005 It's OK to run the setup the way that it is. You can run an 8ohm cabinet with a 4ohm head, just not the opposite. If you run too low an impedence, that's when you end up with problems. IE: 8ohm head to a 4ohm cabinet.

Members Raskolnikovs axe Posted October 11, 2005 Author Members Posted October 11, 2005 Awesome, thanks much.
Members oldivor Posted October 11, 2005 Members Posted October 11, 2005 If it is a tube head it matters alot more then a SS head.
Members Raskolnikovs axe Posted October 12, 2005 Author Members Posted October 12, 2005 why is that? out of curiosity. I ended up getting a Peavey Mark VI - total shipped cost for the peavey and the avatar is like $360. I think I did good
Members LittleWoodenBoy Posted October 12, 2005 Members Posted October 12, 2005 Tube amps can't automatically switch impedances like solid state amps can. Most tube amps have a 4 ohm and an 8 ohm output which need to be used for the respective cabs/cab combinations. I don't know the specific electronic details, but that's the case. But since you got a solid state head you don't need to worry about that.
