Sorry there may be an easy answer but how can u tell if a 4 Ohm sub is 2 Ohm stable???????? or are more or less any of them are?

lol sorry, thanks a lot tho

the impedance of the speaker is a static value.
if the sub is 4 ohms, it's 4 ohms.
how it's wired to the amp, particularly if there is more than one speaker, determines the load at the amplifier.

a single 4 ohm sub on a mono amp will always be 4 ohms.
if you use two 4 ohm subs on a mono amp, the final load depends on parallel ro series wiring for the two subs. parallel would halve the load. series would double it, so 2 or 8 ohms respectively.

oh and stability refers to the amplifier.
amps are rated stable between certain loads.
usually between 2 and 4, or 2 and 8 ohms

actually u say if you have 2 subs on a mono amp wired in parallel you will half the impedence to 2 Ohms, what about if u had a 2 channel amp wired with 2 subs? could that be wired to 2 ohms? (in parallel)

if you have a two channel amp, just get a pair of 2 ohm subs (or dual 4 ohm coil models) and you'll have a stereo 2 ohm load, and peak power from the amp.
