I'll help when I can, I've got a remote start and an alarm I'm working on right now, think I've got one licked (bad brain). Same dude that posted yesterday? With two subs? Repost the subs and amp for me so I don't have to surf too much please. Back later.

If you don’t mind I can try and help you out.

RFD2212 12" HX2 DVC 1000watt sub

501s 2 chan 1500 watt Punch amp

Now your sub can only be wired to 2 ohms (parallel) or 8 ohms (series). Your sub and amp are not a very good match for one another. I would suggest you exchange your amp for one that puts out 500 watts rms X 1 @ 2 ohms. You may want to look at the Fosgate 500BD http://www.purecaraudio.com/index.asp?PageAction=VIEWPROD&ProdID=303 Or the JBL 600.1 http://www.purecaraudio.com/index.asp?PageAction=VIEWPROD&ProdID=324 If you want to use your current equipment ( not recommended) I would suggest that you wire your sub in series http://www.audiobahninc.com/tech/wiring/Series_Series_dual_4_ohm.pdf and bridge the sub to the amp for a total output of 250X 1 @ 8 ohm.

Thanks bberman, I would suggest the same thing for you, you need an amp that is 2 ohm mono stable, a Rockford 501BD or similar amp would do a great job for you if you are going to use only one sub. If you plan on running a second sub, we need to know this now to find the right amp for you in the long run.

You should also look at an Alpine MRD-M500 http://www.crutchfield.com/cgi-bin/S-EL41FJeiRzg/ProdView.asp?s=0&c=3&g=130&I=500MRDM500&o=m&a=0&cc=01&avf=N

or a JL audio 500/1 http://www.jlaudio.com/amps/5001.html

Be very careful on the amp choice, I would still highly recommend one that is a closer match to output power, unless you are not going to be playing your system long and loud. Usuallly with only one sub most people ask a little more of it though, or expect a little more, thus the smaller amp you are considering is a great way to damage your sub. The x figure should be = to that of your rms power of the sub. Now it does not have to be exact by any means and most Rockford amps are totally underrated. The smaller of the two amps would probably do most people just fine for anyone exect the hardcore bass junkie that wants to annoy the neighbourhood.

To wire in parallel is fairly easy. What you need to do is hook 1 voice coil up to the amp just like you normally would, the second coil is hooked up to the first coil, positive to positive and negative to negative.

I've decided on a smaller sub, a HE2 12" 800max -400 rms, then the 501M amp is 350 rms @ 2ohms. no damage done correct? from what ive gathered that appears to me a good match, but what do i know. is that a nice match?

HE2 is a nice sub, more suited to a sealed box and sq than loud and big bass like the HX2. If you are on this path, the match is good.
