So... Ive had a rockford p3d412 for almost a year... I hate it. for 600rms i just expected more. Everytime it gets so close to doing good it clips like crazy. My old sub was an infinity kappa 120.9w 12 inch. The sq wasn't all that great that i remember but dang it rattled everything and now i miss that feeling. So the question is, i have an alpine sa 60m amp that gives 600 rms at 2 ohm. I really don't crae much about sq im so hungry for spl so what 12 inch sub, under $400, would work well with my amp, and give me a little more spl. ive tried vented and sealed enclosures, different size power and ground, and even different head units, just let me know what you think for a new sub this thing isn't cutting it.
**side note.. is it bc that amp is trash or is that a decent mono block ? just wandering thanks

Throwing new sub(s) at this probably isn't going to be your silver bullet.
Even with the sealed box I built to spec, performance is poor, just watching the cone I can see there's barely any travel before clipping

Weird. I have the same sub in the 10" version and it is pretty loud. Shakes the car. Maybe sealed isn't the way to go.

I see lots of videos of them online with lots of travel, I've been toying with my setting from gain to the eq and I just can't get it to travel half as much as other guys have. If I could get mine to move like others I know it would be amazing but mine just doesn't hit

Just seen a review on my amp of someone running a 500 watt L7, said it clips all the time never had that problem before and sounds like me ... Blame the amp?

I used to be a Rockford Fosgate fanboi. I can tell you, P3's do not like sealed. They sound ok but have no output. In a proper built, proper tuned vented enclosure, they come alive. That pre-fab is not doing that sub justice. Take the money and have someone like Brian Horton over at www.starrmountainsound.com build you an enclosure. Or if you are capable of building yourself, have @Buck design you and enclosure and build it yourself.

Had my gains set at the shop so how do I build a box I asked ?
The simplest way to build a ported box is go with a rectangle box and slot port ...draw up a box to subwoofer specs ..use 3/4 Birch or MDF ..both can be bought at lowes or home depot .
You'll need 1 sheet...figure your box cut sheet ..go to Lowes or HD either will have a nice customer based table saw ... tip the guy cutting your box a $20 and tell him you need it cut to specs on your cut sheet ...while he's cutting your box ..pick up liquid nail and #10 2" decking screws go back get your wood...pay for it all...
go home and assemble..give liquid nail 3 hours to dry ..then cut circle out of box to fit subwoofer and your ready to go ...you can paint or stain your box or even wrap it in shag carpet or something if you want it to look better...and you'll be ready to jam on ....
