KennysFord Posted March 24, 2009 Share Posted March 24, 2009 Hey folks. As i'll be the new owner of a 2ohm capable head in the coming days i'm wondering if i can re wire one of my 410's to a 4 ohm cab instead of 8 ohm.The four drivers are all 8 ohm each.The cab in question is 600 watts capable so it'll be grand as owt if i can. PS,i can't afford a new cab. Apologies if this has been covered before and thanks in advance. Quote Link to comment Share on other sites More sharing options...
BOD2 Posted March 24, 2009 Share Posted March 24, 2009 Nope - sorry can't be done. 4 x 8 ohm in series = 32 ohm (pretty useless) 4 x 8 ohm in parallel = 2 ohm (not advisable) 4 x 8 ohm in series/parallel = 8 ohm (which is what you already have) There aren't any other options that use all 4 drivers.

Good news though - you wouldn't get any benefit from turning it into a 4 ohm cab anyway. It wouldn't be noticeably louder (maybe 2dB) and the amp would get hotter.

KennysFord Posted March 24, 2009 Author Share Posted March 24, 2009 (edited) Thanks for replies chaps. I did check in with pete (greeneking) before but just to be sure. If i go from the amp into my 8 ohm cab then out of that into the 4 ohm cab I'll get the 2.6 ohms.I got that bit.If i use just one of the outputs from the amp will it see an even 2.6 ohms or will the second cab in the chain (the 4 ohm one)still get more power than the first.Other than that will the amp see them both as just one 2.6 ohm cab ?? sorry for the confusion.

KennysFord Posted March 24, 2009 Author Share Posted March 24, 2009 Thanks for the reply, so i'll be ok to run it like that for the time being till get either some 4 ohm drivers or better still a cab. Thanks again. Quote Link to comment Share on other sites More sharing options...
