1 ohm vs 4 ohm Question

[Ginobli07 0]

I currently have a 2010 Fi Q12 in a sealed box powered off of a JL 500/1v2. It sounds great, but I want to unleash the sub's full potential by giving it all of it's 1000rms rating. I plan on putting in a high output alternator, so suppling power isn't an issue.

The sub is dual 2 ohm, so I can wire it to either 1 or 4 ohm. My question is: Is there a noticeable difference in sound quality if I push an amp at 1 ohm (if stable) vs 4 ohm?

The reason I ask is because I was looking at Rockford Fosgate Power amps and the T1000 Constant Power was stable at 1 ohm to 1000rms, while the T1500 Constant Power was capable of 1000rms at 4 ohm. While money isn't a big concern I would find it pointless to buy a bigger and more expensive amp if I didn't need to.

Thanks guys

Get the 4ohms (i have no reasoning behind this)

No

no difference in sq.

Those T1000's put out closer to 1500w anyway.

You don't need to buy a more expensive amp so you run 1000watts at 4ohms, 1ohm is fine.

But the T1500 only does 500watts at 4ohms, not a 1000. It also does 1500watts at 1ohm

The new 1500 Constant Power amps do 1000rms at 4 ohms.

My mistake, didn't see the new model. That's different, an amp that does 1500watts at 2ohms or 1ohm...

If you think you might want to upgrade your subwoofer down the road than I'd get an amp that makes even more power and then you'll have plenty of headroom (and since money isn't an issue )

The Q was not designed to be loud, all though it can get loud in a ported box.

As far as any difference? No!

No! with authority. :-) You have practical experience to back that up I take?

I was looking at the new PDX (1200rms) too. I figure the second series should have many of the original problems ironed out.

Not with the Q personally but what I have read and what other members have said it is strictly a Sound Quality Subwoofer.

You may want to look into The SSD, which I have experience with and that is a great all around subwoofer. Loud, low and still remains musical. If your stepping up in power then look into the BL or the big daddy BTL.

I meant with the ohm load. I know about the sub, I already have the Q and I'm happy. I just want to fully unleash it, that's all.

Got ya!

Still not to sure your going to audibly hear a difference!

If you can spend what you want, take the most powerful amp, and play it at 4 ohms : it can't be bad for your car.

But, understand that you don't need it, 1 ohm is fine for subs !!!

For future upgrades, like a 2nd sub, you will be happy to have more power available !

You will never hear difference in 1 or 4 ohm.

1 .0hm bro save money. Only way your going to hear a differnce in sq if you went to 8ohms.
