2 sr124 recommended impedance

Ecin

What's the advantage of me paying more for a 1400.1 @ 4 ohms vs me saving on a 1400.1 @ 1 ohm?

btw it is safe to overpower these subs how much? 1600? 1800? 2000? for the pair. thanks

Ecin

can they do a 2 ohm load?

Ecin

anyone?

i dont think its safe to overpowered, the reason for buy a big amp, its to have headroom.

use it at 2 Ohms if its a DVC, i would use, MTX, Kiker, JL or Alpine for the amp.

i have 2 subs so i need 2 amps?

Kinetic

just one amp and a good enclosure, (read very very carefully the white paper).

anyone between 1,000 and 1,400 W RMS would do the job

The reason why the 1400 @ 4 ohms costs more is that its a much more powerful amp than the one that can do 1400 @ 1 ohms. The 1400 @ 1 is at max power then. The 1400 @ 4 would likely make 2400 @ 2 ohms and if its stable down to 1 ohm it might make 3000. Thats why it costs more.

Ohms are a measure of resistance and its what basically regulates the amp. Unrestricted, the amp would make its full power limited only by its input voltage, but not all amps are built strong enough to withstand that and would fry. So an amp rated to 2 ohms means that the amp isnt built to handle the power output it would make if it only had 2 ohms resistance holding it back. Not all amps are stable down to 1 ohm or even 2 ohms mono. Thats why you have to match these ratings with your sub configuration.

For example if you have a pair of 4 ohm, single voice coil subs then you need an amp that will handle a 2 ohm mono load. If you had four 4 ohm single voice coil subs or even a pair of 4 ohm dual voice coil subs then youd need an amp able to work at 1 ohm.

If youre NOT using SR124DVC's then you have a 2 ohm load so you need an amp that makes at least 1400 watts at 2 ohms.

As for overpowering, its not that simple. Sticking a 2000 watt amp on a 1000 watt speaker doesnt necessarily mean youre automatically overpowering it. Say your car is capable of doing 120 mph. Does that mean that as soon as you start it up, youre instantly doing 120? Same thing with an amp. That 2000 watt amp isnt always making 2000 watts and so long as youre listening to music at a musical level and NOT listening to sine bombs or ghetto blasting bass at full tilt volume, the bigger amp will give you better sound quality due to more headroom and better dynamics.

Bottom line is use common sense with the gain setting and volume control and you can use bigger power and get better sound. Be stupid and overdrive your subs and youll have a very expensive but unique set of bookends.

I have a pair of sr124dvc, and I do want them to get loud.

Do I need an amp 1 ohm stable?

what zx kickers can I get? since I can get them cheap through my job's accomodation program. should I get a pair of 2 ohm stable or 1 4ohm amp? once again, I want them to be able to get loud. But I don't want them to get stuck on a note but hit fast.
