getting my optimal setup..

so, as i recently used, i cannot use my 2 8x10s in parallel because it would equal 2.67 ohms, and my amp has a 4 ohm minimum. I'm going to eventually buy a new amp that is 2 ohm capable, but in the mean time i want to get the most out of my 2 8x10s.

i am currently only using 1 of them, and the other one is sitting there looking pretty and fridge-like. i want to make both of them talking fridges.

i have a:

ampeg svt 810, 1x4 ohms or 2x8 ohms
crate bx 810, 1x8 ohms

as i've been told (please correct me if i'm wrong), if i wire the 2 halves of the ampeg in series, i would have a total of 5.33 ohms. I also found out that all of the inputs of the ampeg 8x10 are ins and outs. so...

(as a note, I'm referencing the input jacks as they are numbered n the product manual, from here:
http://www.ampeg.com/pdf/SVT810EAV.pdf)

i wire from one amp output to the ampeg input jacks 2/3, then out of another 2/3 into 1. then from the other amp output to the crate imput.


would this effectively put the ampeg in a series 2x8 ohms, with the crate in parallel, giving me 5.33 total ohms?

yes, i know that 2 8x10s are unnecessary. i know it's pointless. i want to do it anyway.

i hope somebody can tell me that I'm correct, but if not i'll just wait until i get my next amp.
 
No................

Input/Output jacks on amps and cabs are wired in parallel.

You need a specially built cable to wire in series.

And............even then, wiring your 2 halves of the Ampeg together will give you a 16 ohm load

If you then add the Crate, yes, you will be presenting a 5.33 ohm load to your amp.

Why would you want to give a Crate cabinet twice the power of an Ampeg though ??????

ok, then, i can't do it. oh well.


i don't know how / why i would want to send a crate twice the power of an ampeg...to be honest, this is all very confusing. up until now i've always been plug and play.
 
I highly suggest you use just one 810. They are two different brands and both of them sound very different. Combining them is not going to sound very good at all. I highly suggest you use the Ampeg 810e in the 4 ohm mode with your head. Plug & play at it finest. Using two 810's onstage is nuts to be honest. Two Ampeg 810's without a PA is no big deal, but one 810 should be just fine in any situation.
 
i think you'll be getting the most out of the crate by slapping an ampeg grill on it, leaving it unplugged, and pretending it's another ampeg cab ;)

actually i'm kidding. you could try buying another amp to run it separately if you want to use it. maybe see if you could get a deal on a cheap tube head and run it as a dirty rig. running a separate head would be much preferable to running both with the same head imho.
 
+1 for what JimmyM said.. Run a true stereo rig by signal splitting via aby or any stompbox with 2 outputs. most mxr and boss have these as do others.. just a touch of reserch is all man. with cleans into the ampeg and dirtys/efx into the crate.. This is currently how I am pursuing except I am running 2 ampeg svt15en and a hartkeha3500 and want to get a 6x10 with a hartke ha5500 and run my board to the 5500/6x10. Good luck and keep on rocking in the free world!!! :hyper:
 
There would be another solution: Get a cheap poweramp and run it slaved to power up the second cab.

This means: Use your amp with the Ampeg cab, get out your "slave-out" of your amp into the input of a poweramp and run your Crate-cab with that poweramp. If the Crate-cab is louder then the Ampeg-cab, you can dial that in with the volume-knop of the poweramp.

I don't know, what amp you use, so I don't know if it has a slave - out. Take a look at the manual to get sure.
