Theres been a few posts covering this...some saying do it, some saying dont... a bit of misinfo as declared by some and some simple logic that made sense.
question is, can you use 4 ohm aftermarket speakers in the place of the 2 ohm speakers with the stock 2 ohm amps and stock radios.
from the majority of the posts here, and the other 2 forums of which one i cant mention due to issues between..., and a random forum that came up on google but was posted back in 2005

many have stated you can use a 4 ohm, but the speaker would recieve less power than the 2 ohm speaker, however NOT MUCH OF A DIFFERENCE IF you purchase an aftermarket speaker to where the "sensitivity level" is greater than the speaker you are replacing.
so basically if i go from a 2ohm speaker with a 86-88db sensitivity rating, to a 4 ohm speaker with lets say 93db sensitivity rating, then there shouldnt be much of a difference....correct???
and because the speaker is recieving less power peak and RMS, the amp should more or less be working less, since it isnt powering the speaker at full tilt?
all of this sound correct? or any info someone wishes to include to kinda settle this quandry, please add on to here.
thanx in advance for any answers given
listening...

i dont see the amp working less though. you are putting less of a load on it yes, but the amp should still be working just as hard. without matching the load of the speaker to the load of the amp, its just wasted power. basically, your amp/speaker combo is less efficient with a 4 ohm speaker then it is with a 2 ohm speaker hooked up to it.
if the sensitivity is higher than stock, then you should notice very little to no difference if nothing else changed other than the load from 2ohm to 4 ohm and the sensitivity. how ever, thats not usually the case. speaker cone area would probably change a most people do not stick 4x6's back in the front once they have replaced the speakers. also speaker cone and surround material will probably change too.
so will it work... yes.
will it be better... depends.

i have actual proof of this....
i have stock monsoon deck and amp, with aftermarket JLs. The speakers are plenty loud. cranked full blast they still pound the car like the stockers would. so yes 4 ohm speakers work on a 2 ohm system. only real difference is that i do turn it up full blast, cant say i ever cranked it full with the stockers so technically they are quieter but witht eh sensitivity of teh better quality speakers it does nto make much of a difference.
My car may run 18s, but I can do your taxes in 10 seconds flat.
JBO lube - they would never have enough in stock and we'd never see RodimusPrime again
thanks for all that answered....seriously.
the amp in question is a stock boston accoustics amp, which is a 2ohm amp....so before anyone says "that never came in a J-Body"... yes i know....or at least i dont think they did. this is basically for my 2007 Dodge Charger. I'm toying around with the idea of a possible replacement of the door speakers (some big f***s, yea?) cause even though they are BA's, they are still paper speakers.
not really doing it for a huge increase in sound, but just something that can suffice as a replacement that will last and be at least similar to my stock setup. my view, its already loud enough
but seriously, thanks for the help. some of the newer forums i go to do NOT have the amount of knowledge as with this site. people still believe the jet module works, even after a few have posted sheets showing loses of power. trying to adapt, but its like taking a step back sometimes with a few of the new forums.
Another thing you gotta consider too bro is a rule of thumb - lessen the resistance, cut in half the power. For example, your amp might put out 30 rms @ 2 ohm per channel, you might only get 15 rms @ 4 ohm.
yea lanman hit it....you might be sending half the power to the new speakers. Try to find 2 ohm after market speakers to get the "best" results...i know the charger uses 6*9's all around. But there is nothing wrong with using 4 ohm speakers...just that youll most likely lose power. A 2ohm speaker might be the best way to go, you can also test it. Buy a set for the fronts (from some place that will take a return no problem) and change the fronts....then use the fader to fade between the front and back to see if theres a big difference and go from there!
