21V -Subwoofer installs?

[pap]

Thinking about putting a sub in this year. Problem is under the helm where it appears most people put a sub box, there is the heater vent right there.

Anyone have install pics of a subwoofer in a 2009+ 21V? Advice?

I'm also a bit leary of building my own box. Sounds complicated to get it just right.

Doing some early planning

I do not have any pics of a similar boat, but its not hard to relocate the vent. it should be connected to the heater with a flexible tube. In this case, the front wall of the sub box will actually be wider or taller then the actual box. No just drill a hole and remount the heater outlet in the outer portion of the front wall. Once installed, it looks clean and factory.

There are pics of this type of install on the Moomba site in the audio/stereo thread. Good luck!

i'm checking there as well. I think I get your idea: build a box offset and then a false front that extends beyond that and put the vent in that?

I just have NO idea how to properly build a box and the ones I've seen look both geometrically challenging as well as I know you have to get the volumes just right.
Was hoping someone here had already done it and could get some direct feedback for my specific boat.

Typically a Supra 21V has a flat sole under the driver's helm which makes this considerably more friendly than a 22 or 24V with a pronounced floor hump.
You may have minor obstacles with the steering cable route or heater vent tubing or a small floor elevation or the hull narrowing towards the bow.
Once you remove the cover facade and armed with the knowledge that you can re-locate the heater hose/vent, the maximum external dimensions are pretty easy to determine.

So anyone want to chime in with a driver/amp recommendation for that spot on a 21V? I most certainly do not want "boom/thud" bass, the type you hear from ricer cars that are vibrating themselves to death. I just want a very solid, musical lower end. The only time we really turn our system up is when riding to get sound to the rider and generally at that point it's a battle between wife saying "turn it down" and rider saying "can't hear it, turn it up"
