4 ohm or 1 ohm???

[DaveVT 10+ year member]

Ok, I can wire my subs at 4 ohms or 1ohm.....My amp will put out 1200w from 1 through 4 ohms. Is there any difference between the two wiring options other than the current draw?. It should be just as loud at 4 ohms as it is at 1 right?

4 ohm will sound alot better, more resistance more SQ. the output will be the same jus sound better

how does more resistance affect sound but not output?

the amp is best at 2 ohms but is still more powerful at 1 than 4 but not by much. At 4 you may get 1250-1350 and at 1 you may get 1300-1400.

double the current draw at 1 than 4 also. With my stock electrical 4 seems like the best option. Plus, 600w to each of these 8's should be fine. Its already 200w over rating.

4 is the best option for sure.

What amplifier are you using? If it's the same RMS output regardless of the Ohm load the current draw should be the same. It's Ohm's law. You can't have more current draw and not get more watts.

Regarding SQ vs. subwoofer Ohms, you're not going to have worse SQ by running a lower impedance. People mistakenly believe this, mostly because manufacturers state the BS "damping factor" specification.

1200w @ 1,2 and 4 ohms. According to what ive read it is able to do this by upping the rail voltage to what it needs to achieve 1200w at all ohm loads. All meaning 1, 2 and 4 of course.
