1200 Watts and nowhere to go...Subwoofer question

[Tallredrider]

I am planning the subwoofer install for my G23. I have an Arc Audio 600.2 which will give me 1200 watts bridged. Only downside is that it is only stable at 4 Ohms. I would go all out and get a JL W7, but it only comes in 3 Ohms. I could run it off of just one channel, but it would only get roughly 450 Watts.

I think I'm looking for a 12 inch subwoofer with 2 Ohm dual voice coil in a sealed box that I can put next to the garbage can on that shelf. I am thinking of getting the Wetsounds XXX as it would fit the ticket, unless someone can give a compelling argument to go another direction...

Ideas?

Yes, you are bound to a 2 ohm DVC for that setup. I would certainly entertain the Kicker L7..........i hear Wal-Mart sells them

Did you consider the JL CS2120G-W6v3?

The W6 only comes in dual 4 Ohm voice coils. I could just use one channel on the amp...but it seems like a shame to not use all the power I have. 600 watts is the max recommended power.

As a packaged enclosure the dual driver CS2120G-W6v3 will handle 1200 watts.

Are you thinking of building your own enclosure?

I googled the sub you suggested and got bogged down in 12W6v3, and somehow did not spot the precise one with dual drivers. That looks like a pretty mean box right there.

After looking around some more, I kept coming back to the W6 and decided just to get one. I like that the sealed box specs are smaller than many, and it will fit nicely wedged on the shelf beside the garbage can. It will be a tight fit, but I'm pretty sure it fits. So a JL audio W6 is on its way. I have a free channel that I can use for a second if I feel the need.

So series the voice coils and bridge the amplifier?

So series the voice coils and bridge the amplifier?

The amp specs state that it gives 1200 watts at 4 Ohm bridged or 600 Watts per channel at 2 Ohms. There is no mention of 8 Ohms. Would bridging the amp with the sub in series effectively give me 600 Watts of power, the same as I get from 1 channel at 2 Ohms?

Might there be an advantage to that I am unaware of?

[David Analog]

The 12W6 deserves more than the conservative 600 watt rating and unregulated amplifiers produce about 25% less power with a more realistic 12.5 volt supply. So the 400 watts is terribly lite.
Bridged 8-ohm power is the same as the collective stereo 4-ohm power. So bridged into an 8-ohm load will give you 800 watts. And still 600 watts at 12.5 volts. That's good power, especially with the headroom of an amplifier having a 1200 watt power supply. It should clip gracefully. Pretty darn close to ideal.

Since folks are throwing JL recs suggests money isn't an issue... A 12w7 on that amp bridged at 3ohm will be right around spec rms 1000w. Squeeze every watt out of it you can. I don't know that I could justify the price of the W7 over other quality 12" 1000-1200w offerings.
Also I don't know that I'd use a large in size and pricey 600.2 to power a sub unless I just had nothing else to do with it. There are better suited amps for subs and it's hard to find a better amp for towers and maybe inboats than the 600.2. But with what you've got to overcome getting sub freq's out of that compartment... Consider it a 30-50% deficit trying to blast sub freqs out of that compartment compared to the Malibu with it at your feet.. And don't be overly optimistic about how much a 12" vent will help.

I found a w7 in my local classifieds that was used but in great condition so I was stoked to get it. Then I found that the 600.2 has some interesting specs. It is not listed as 2 Ohm stable when bridged, just 4 Ohms. I called the guys at Arc and asked about 3 Ohm, and they said it will definitely not work on a W7. They don't make the W7 in any other configuration, apparently. I've never seen one in person, but I don't think you can mess with the wiring to make it 6 Ohms, either. He also had a JL 750.1 to go with it. I lowballed him $500 for the whole setup and he said 'No Thanks'. My 600.2 was already paid for at that point, so I was kind of stuck on it.

[David Analog]

The JL Audio W7 is always a good investment. If you ever damage one you can get it rebuilt at a reasonable cost considering the cost of one new.
I do not see how the 600.2 in any configuration can properly run a 12W7. I would want a bare minimum of 1000 watts. Many run this sub with a 1200 watt strictly regulated amplifier (will deliver a full 1200 watts under any common conditions).

I would suggest the Treo SSP. 1000 watts RMS so you don't have to run the amp at max capacity. Comes in Dual 2 and 4 ohm. I've got the 10" in my boat and everyone always thinks it's a 12" sub. Hits hard with nice clean bass.

I got my 12W6v3 D4 installed last night. I am very pleased with the sound it makes. The box fits right on the shelf next to the garbage can.

I told the wife I was considering a W7 in a ported box that would replace the trash can, and that it would be probably the best bass she has ever heard and she suggested that the location of the trash can was worth spending 6 figures on the boat and I should do whatever it takes to preserve that. Unfortunately, I have a lot of crap in the storage and the Roswell box takes up too much of that, besides the fact it costs $700. The box I purchased fits perfectly right next to the trash can, which was probably an area that does not see much use anyway.

I found the best price on the subwoofer at Car Audio Giants by a fair margin.

I bought this box and it seems well made. http://www.ebay.com/itm/12-CUSTOM-SE...4253c9&vxp=mtr

For now, I just left it at 2 Ohms and ran 1 channel to it for 600 Watts. I may tinker with it in the future, but for now I am pretty tired of crammimg my 6'9" body into that compartment. I ran new power, distribution blocks, RCA cables and 3 amps. I have wires that desperately need to be cleaned up, so I did not take any pics yet, as it looks pretty sloppy.

One of the reasons it looks so sloppy is that I have RCA cables dangling all over. I ordered my dual zone volume control from Roswell 2 weeks ago and it still has not arrived. The person I talked to at Nautique Parts could not find it, so I ordered it through Overton's. When I called Overton's asking where it was, they told me it ships directly from Roswell and they then sent an email asking to have it sent. Maybe I should have went with the Wetsounds 420, at least I would have it by now.
