So i have an Eclipse 12" titanium hooked up to an Eclipse DA7232 (4ohm dvc & 1000w x 2 @ 2ohm or 500w x 2 @ 4ohm). Currently the sub is wired in parallel and connected to one channel of the amp giving me 1000w @ 2ohm.

I have the option of giving the woofer 500w to each voice coil @ 4ohms by running one vc directly to each channel.

I remember hearing that sq gets better with more resistance.
Is this true? Would the 4ohm config. sound noticably different compared to 2ohms?

No harm in trying this and finding out for yourself. As this is purely subjective, it is up to you if you hear it as being better or worse.

Having HAD that very combination, the stero option, running 4 ohms per channel is still FORMIDABLE... You will not be disappointed, at all. The control will be higher than it is right now, and the amp will run cooler )nott hat it runs even a little warm anyway...).

I don't understand why you decided to waste one channel of the amp in the first place...

cool, thanks. you think that's a waste? i have a second titanium just sitting at the house...it kills me. I just figure with all that power it wouldn't make much sense to run both channels at 2ohms on a stock alternator.maybe some day...

haemphyst, did you use a sealed box when you were running this setup? that's what i have right now but i was thinking about trying a port, just don't want to sacrafice the sq i'm enjoying so much posted_image

The SQ on that woofer is AMAZING... If you have a second woofer, put it in, man! Using both channels, even at 4 ohms, will put the same amount of power into one woofer as running one channel to it at 2 ohms, and your damping factor will be twice as high, (for better control) so, yeah, that's a waste (IMHO posted_image

). Now, you've told me you have two woofers, use each channel at 2 ohms then, sure. That's what the amp was made for! You'll LOVE it! You'll gain 3dB, but it should sound just the same, only louder!

I was using a sealed box, just shy of 1 cu. ft., (net) which is a bit small for the woofer, but I went for a little bit higher Q to improve power handling (at the expense of extension).
