Subwoofer Mounted to Rear Compartment

[Runnergade]

Okay guys. Measure twice and cut once right? So I need some expert advice.

I want to cut a circle with a 7.25 inch diameter in this cover for the rear compartment for a subwoofer. You maybe able to see the circle in this photo.

The depth of the compartment is about 4.5in.

I found a 8in free air sub-woofer that doesn't need a box, has a 2.5in depth, and good reviews on Amazon that I want to pop in that hole. I'm not looking for boom, just a nice kick. I'll then cut out an 8.25in diameter circle with an 7.25in diameter hole from some MDF that I have laying around to go behind the cover to provide better mounting for the sub-woofer screws. I've also seen some amps that maybe thin enough to fit inside with the remaining inches of length, width, and depth.

My main concern is if this cover is strong enough to mount the sub and handle the 120Wrms power. The reason I'm considering doing this is because I don't want to lose any cargo space to a box. If anyone has any objections please speak now or forever hold your peace!

I haven't seen one done on that location but i don't see why you couldn't make it work. Although I wouldn't recommend mounting the amp in there due to lack of airflow. Your amp will cook without being able to breath. I myself don't care for the "boom". I'm more about clarity. I did sorta the same in my tundra in the compartments under the rear seat with 3 8" infinity's and it sounds great.

Whoa! Sorry bout the sideways pic but you get the idea.

There was a guy that did it on TTORA, I think.

Used an 8" woofer, and it looks clean.

I wouldn't do it. The woofer needs to be mounted to something solid. The cover will vibrate & the plastic clips aren't strong enough to hold the weight. The amp also needs airflow to keep it cool.
My 12" JL Audio sealed box Sub is tight with no "Boom". The JL Audio amp is mounted to the back of the seat.
When I need cargo space I just disconnect the 2 wires to the box & put it in the house.

Wow that looks real clean! I bet that's got a nice kick to it. I'm inclined to just try it out and see what happens.

You might find some of the other threads useful in helping with your project.

I don't mean to discourage this thread in any way, please keep posting. I just wanted to let you know in case you haven't seen them already ... There are several build a rear cargo subwoofer threads on this forum -could be helpful.

You will of course have to search. I would suggest using the method stickied at the top of the 3rd gen section.

Looking forward to the updates!

Thanks man! Give it a shot but try cutting a piece of ply instead of your factory panel like I did in case it doesn't sound right. That way you could always go to plan B and not have a big hole cut into the cover. You might have to find an alternative way to mount it but it's worth a try.
