OK Guys Heres What Ive Got, I Am Running 8 Ohm Subs Single voice coil. I have no intention of changing subs or amps. My Amps Are All 1 Ohm Stable. How Do I Change My Subs From 8Ohm To 2?
Can This Be Done By Running Resistors in Parallel with the subs?
What are you trying to accomplish? How many subs do you have? Are you trying to figure out how to run multiple subs of 1 chnl? Adding resisters are not the answer.
By bridging the two extra channels, you will be to a 4-ohm load. I don't know of any way to get it lower than that with the setup you have. Also, don't know of many 4-channel amps that are 1-ohm stable... so that might be worth double checking?
Sorry to say, what you got is what you got. You can lower the Impedance that the amp sees, but the extra watts output would be lost to the resister(s) in the way of heat.
"I thought that only the speakers determined the ohm load"
The speaker and the amp each play a part in determing the ohm load. As far as the amp is concerned, 8-ohm bridged to two channels is the same thing as the amp seeing a 4-ohm load... don't know if that makes sense... ohms are confusing and I'm sure somebody else on here is able to explain it better.
Unfortunately I don't think there are many around anymore. But they let you divide or multiply the impedance seen by the amp. We used to use these 10 years ago in sound off's to get the most out of our amps. Anyway, there you have it. It does/did exist.
