Hey fellas, I'm looking to buy two Cerwin Vega Vpro 12" subwoofers and am really stuck on whether or not I should get the dual 2 or 4 ohm versions.
I'm looking more for SQ than pure SPL. But at the same time I want to maximize the amount of bass for the money spent.
My amp is Audiopipe APSM-1500, which is rated 1400 x 1 @ 1 ohm RMS and 950 x 1 @ 2 ohm RMS.
Now I understand that to maximize the output of the amp, I'd need to go with the 4 ohm version of the subs, for a 1 ohm mono load. But my question is, do I really need to? These subs are rated 750w RMS, which I suspect is WILDLY overrated, I'm thinking they can handle 400w RMS long term. My box is a ported 1.75cf per chamber tuned @ 35 hz. Will I get a huge amount more bass output by wiring at 1 ohm instead of 2 ohm mono, and is that extra output worth running the subs at their maximum limit, where it's questionable how well they'd hold up at that power?
My thinking is that a 2 ohm mono load would be easier on the subs and amplifier, at the expense of some some maximum volume with some extra SQ. I'm just curious how much potential volume I'd be leaving on the table. Also the dual 2 and 4 ohm versions of this sub have slightly different T/S parameters-- the dual 2 ohm version has T/S params that favor a ported box a bit more than the dual 4 ohm. Curious what you all think. If there are any other subs substantially better than the CV I'm considering for around $100, please feel free to comment on that too.
