Way to change Ohm load capability
 
Is there any way to change the Ohm load that an amp can handle? For instance making a 2 channel amp capable of doing a 2 or even a 1 Ohm load bridged when it normally would only be able to do 4 Ohms bridged? Like upgrading the mosfets or caps or ...?

If this is a dumb question please feel free to kindly let me know.

Halving the load resistance means doubling the current, which means quadrupling the power lost in the system.
It would take rebuilding the case, rewiring, doubling up and/or replacing all the mosfets/transistors.

Adjusting design settings, protection circuits, gain settings, etc you may get away with as is.
not too much work really...:rolleyes:

Ok I kind of figured that it would be something crazy like that. Thank you for the info.

What about a big honking resistor on the high level outs? :)

The reason that I ask is I have a Kenwood KAC-1023 that is a monster that I would love to mod if possible.

What about rewiring the speakers instead?

I no longer have that sub I now use a pair of subs (one is the sub in my avatar).

Cal Weldon 15th November 2012 10:43 PM

Are they DVC? If so why not run them in series?

I they are I guess I could but I would need to get some more power from the amp, it is only rated at like 1200 watts.

Cal Weldon 15th November 2012 11:09 PM

Don't worry about it. Watts are not all they are cracked up to be.
