Subwoofer (Rookie here)

[isitsummeryet]

Guys I got a question and I apologize in advance if this is answered but I tried to find the answer to this in other threads but could not. I have a 2018 AR210.

So I have 1 wet sounds 6 channel amp which is powering 4 wet sounds 6.5" deck speakers only. 1 on each channel. This year I ordered a 12" (open air) subwoofer from Wetsounds and this thing is a 30lbs. beast! Link to what I ordered :-

REVO 12 XXX V4-B | Wet Sounds 12 Inch SPL Marine Subwoofer

Couple Questions :-

1. Do I connect it to the same 6 channel amp by bridging the 2 open channels or will it need just 1 open channel. Or does this beast need it's own seperate amp?

2. Since this subwoofer is so damn heavy, do I need bracing or some sort of wooden structure behind the fiberglass to install it or how does that work?

I am a mechanical engineer and a total rook when it comes to sound systems. Did the first install myself but now I ordered a giant subwoofer without really researching much. I guess I was impulse shopping as a typical boat junkie. Any help really appreciated.

Thanks

Yes, you bridge the 2 channels together for the sub. Im not sure if the amp you have will be big enough to run that sub, it requires a lot of power. For the weight i would use 3/4in starboard at least to mount it.

 

[John Mcpartland]

It looks like that sub needs to be in a box, not IB if that was what you were wanting

 

[isitsummeryet]

What is IB?

 

[John Mcpartland]

Infinite baffle. They dont need a box

You need a different amp. That pushes around 1200 watts rms. Also will need to be 1 ohm stable

I would also put that beast in a ported box

What is 1 Ohm stable? I know ohms well but what does it mean here? Stable?

 

[John Mcpartland]

Most amps and speakers are 4ohm, now there are a lot of amps that can run on 2ohm so you can put 2 4ohm speakers in parallel for a 2ohm load. Your sub has 2 2ohm drivers making it 1ohm and not a lot of amps that can go down to 1ohm and be stable(reliable)

Could also wire the DVC in series to get it to a 4 ohm load if the amp can't do 1 ohm.

That sub is NOT an IB sub and requires an enclosure..... Preferably ported. Like @wTheOnew said, you can wire the DVC in a series to net 4 ohm if your amp can't handle the 1 ohm load (mono). You need LOTS of power for that woofer. If you are not looking to build an enclosure and buy a bigger amp, you may want to consider getting an IB subwoofer.

You will definitely want a different amp for that sub, I don't know what speakers you run but with a peak draw of 2400W from that sub I would think you are going to be taxing that amp without any other speakers connected

 

[isitsummeryet]

Can anyone please suggest the type of another amp I need here? I get confused on channels and mono etc. So I need an amp which is at least 1200W right? Wetsounds amps are super expensive and only one I found on their website was $1400. Anyone know of a cheaper amp I can buy? Any link? Do I need a 1 channel amp for this sub?

 

[BrandonG]

To use the sub at its full potential you are going to probably want a single channel (mono) amp that is one ohm stable and that it going to be expensive, otherwise you will end up having to wire the voice coils in series.

 

[redthumper9]

You can look toward HIfonics amps if you are on a budget, but I can't speak to their quality. I have the same sub running off of a Wetsounds SD2. It pounds! But regardless, you'll need to build an enclosure for it.

Guys will something like this work?? Are the specs right? 1 Channel 2500Watts? It's not super expensive.

That would work

Looks good to me. Are you in Salt or fresh water?

 

[isitsummeryet]

Mostly fresh. Salt maybe 2-3 times a year.

Expect MAYBE half of what its claiming power wise. Go for Kicker, Rockford, JL if you want to get actual power the amp is rated for out of it.
