[QUOTE="jedwards83, post: 8665164, member: 634244"] 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 [I]some[/I] 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. [/QUOTE]
