Sub and Amplifier Help

I'm fixing to buy 2 Alpine Type-R 12's and I was wondering which ones to get.... I emailed crutchfield and they told me to get the dual 4 ohm ones and wire them in parallel and use the Rockford Punch 601s... i think that's it (300 watts x 2 channels (2-ohms) .... anyways they said it would put out a 2 ohm load per sub... and the subs have a 300 RMS peak... so I was wondering if this was the best idea... I was going to get the Rockford Punch700s or something it was called.. it would deliver 375 watts x 2  (2-ohms).... I need help.... and can someone put a diagram of how I would need to wire these things... thanx

Oh... I was also wondering if any1 out there had these and whether they are better in sealed or ported boxes... Thanx

You've got a lot of flexability with DVC's. The subs you mentioned are DVC's rated at 300RMS 1000Peak. The 4ohm model is SWR-1241, the 2ohm model is SWR-1221. If you are going to use a 2-channel amp that is 2ohm stable per channel, then I'd go with the two 4ohm DVC's (SWR-1241). You can either wire in parallel at one sub per channel (stereo) with a 2ohm total load per channel, or wire in series/parallel bridged (mono) with a 4ohm total load. The total watt output should be about the same either way (although the stereo configuration will produce a little cleaner sound then the mono), but you can try both and see which you like better (stereo vs. mono).

Wired in Parallel with one sub per channel (stereo configuration), each sub would look like this


Wired in Series/Parallel bridged (mono configuration) would look like this


RF amps... What can I say besides I love 'em. I've been running RF Power amps for a while now and I have yet to be disappointed. I haven't had personal experience with the 2-channel amps you listed, but... The first thing to remember about RF is that most of their specs are based on a 14.4volt system, not a 12volt system. It's a marketing trick that catches unaware consumers and tricks them into not getting exactly what they thought they were getting (great amps, bad PR dept!). The next thing to realize is that even though the printed specs are not based on a 12volt system, RF amps run very efficient and usually perform above and beyond their rated capabilities.

2003 RF Punch 601s
Based on RF specs (14.4volt)
300 x 2 @ 2ohms and 600 x 1 @ 4ohms
Reality (12volt)
more like 250 x 2 @ 2ohms and 500 x 1 @ 4ohms

2003 RF Punch 801s
Based on RF specs (14.4volt)
400 x 2 @ 2ohms and 800 x 1 @ 4ohms
Reality (12volt)
more like 350 x 2 @ 2ohms and 700 x 1 @ 4ohms

2002 RF Punch 700s
Based on RF specs (14.4volt)
350 x 2 @ 2ohms and 700 x 1 @ 4ohms
Reality (12volt)
more like 300 x 2 @ 2ohms and 600 x 1 @ 4ohms

If it was a choice between the three, I'd go with the 801s. The next best would be the 700s.

As far as enclosures go, it all depends on what you listen to and what type of bass you want to hear. I prefer sealed enclosures myself.
