single voice coil and 2amps

[grizzly 10+ year member]

as the title says i guess ive never tried or thought about the possiblity of hooking 2 amps on 1voice coil. and yes the amps are strapped. but my real question is lets just say for fun you have a single 4ohm voice coil. you hook 2amps strapped on it do the amps both see 4ohm or is it double cause its split or i dont really know. just wondering if anyone here actually knows what happens or can give me some more info thanks in advance. also this is just a idea im not going to try to the near future but who knows might work sometime

i'd like to know too

maybe someone will know during normal daytime hours lol, i think the ohm would raise because its being split but cant prove either way so hope someone can let me know

the load will not change. only what the amps see will differ, but you will fry both amps. so doesn't matter. essentilay you want be inputting two amps to the speaker you be hooking two amps to each other. NOT GOOD JUJU

how will the load not change but each amp see be different???? and how are you going to fry the amps? people strap amps all the time and run 2 amps on 1 sub all the time but its usually with dvc, so how is it any different? just looking for a full answer

i think that the amps will both see 4 ohms. think of it like this, if u hook 2 DMMs to a 4 ohm load with both +s and -s together (parallel), both DMMs will read 4 ohms...just a thought tho.

Each amp sees two ohms. It works the same as bridging except instead of the two channels being bridged being in the same amp they are two separate amps. It can only be done with certain mono amps.

when you bridge an amp the ohm load doesnt cut in half........... again im asking about running 1 single coil on 2amps, does anyone know a real answer? yes josh could test with a dmm but just wondering for fun and wanna know a 100% answer.

Then you don't know how bridging works. The load "seen" by each channel in a bridged pair is half of the final total load. The Impedance of the sub stays the same cause wiring and powering have nothing to do with that. Strapping amps is the same as bridging a stereo amp. Each amp sees half the final load. That is the 100% answer.

yes i understand the ohm of the sub doesnt change and im not tring to piss anyone off. and yes i understand bridging but im talking about 1 coil on 2 amps, i understand how a single 4ohm sub wired to a stereo amp bridged will see 4ohm, so how does your idea lower the resistance, thats based on u saying bridging is same as strapping, how do the amps see a lower resistance? how does that idea work if you have a dvc and each amp gets 1 coil, do each amps see half that load? or do they each see the ohm of the coil on it, which is what ive always thought. or am i just way off. im just wondering

each amp sees half the load.

each amp sees half the load.

is that the same with a dvc?

 

[grizzly 10+ year member]

1 coil per amp

 

[grizzly 10+ year member]

what about a quad coil, lets just say for fun a quad 1ohm sub and you wire 4 amps one per coil, do the amps see .5ohm each?

i understand a single 4ohm sub wired to a stereo amp bridged will see 4ohm

WRONG! the amp will see a final total of 4 ohms, as the sub is a 4 ohm speaker,

however EACH independent channel will recieve a 2 ohm load.

The same applies for strapping an amp for a mono output.

Each amp will read half the final ohm load.
