Running a 4ohm single voice coil sub at 2ohm?

[Aryan]

I am having a single voice coil 4ohm sub with 325w rms I am looking to buy a mono amplifier as i want to make full use of the rms. Also looking to buy another similar single voice coil 4 ohm sub with 300w rms(not 325w rms as earlier because it’s unavailable)


Ques1 Is it safe to run two 4ohm subs at 2ohm, assuming i wire two 4ohms single coil subs in parallel?

Ques 2 since both the subs are similar but not exactly same one is having a little less rms at around 25 w rms less than the other one will it be compatible for parallel connection? Both are 12 inches jbl subs


The mono amps i am looking at have a rating as
300w rms* 1 at 4 ohms
500w rms* 1 at 2 ohms
800w rms* 1 at 1 ohms

You will be fine running both at a final 2 ohm load as long as the amplifier is stable at that ohm load.The 25 RMS wattage isnt that critical between the subs to hear any if much of a difference. Tune both properly and you shoulld be just fine. Id look at an amplifier that puts out approx 600-1k rms @2ohms to get the most out of the subs. Examples to follow below

2x 4 ohm coils can be wired parallel to 2 ohms or series to 8 ohms. There's many amps with 2 ohm power you can use.
