Sorry if this isnt the right category to post this.

I'm quite happy with the setup in my sig, even with 4 channel amp gains at minimum. It's a nice entry level sq setup that I can turn the head unit volume up to 62 without problems on most songs.

But...Im one of those guys who likes to let everyone else hear what I'm playing.

I ran 2 prv 6mr500 v3's in the doors. They were loud...turned heads...but the sibilance (spelling?) Was horrible and it hurt my ears.

So ive decided to run 1-2 6.5 in each rear window. I want to make a bracket that positions the speakers facing out.

The door itself seems to have no usable space so I figured the seat bolt brackets on the b and c pillars would be perfect.

I never have anyone in my car so it would not be an issue.

The plan is to flip a switch that powers the second 4 channel (jp234) and roll the windows down. I would cover the speakers with black grill cloth so they cant be seen.

The amp should be here today.

I want to get this going.

Eventually i want a hinge that locks so I can fold the panel up out of the way.

I figure a 1/8" thick piece of steel would be good. But I'm open to ideas.

If anyone local (925, 408, 415, 209, 916, 510, etc) I would pay or give trades for the help.

Here are some pics of the rear window area.

The ones with my finger are where the rubber door seal sits. So I assume mounting on the door is out of the question.

You want to blast the outside of your car with your music? Am I really reading this? Is this a late April fools joke? The sad thing is I know you are serious.

To be totally honest I think you are hanging out on the wrong stereo related forum.

I live in the east bay. Led underlights and grill mounted speakers are common. This will be more classy.

Got a piece of flat bar mounted to seat belt bolts. Should be solid. If not, I'll go thicker.

No-go on the sealed box. Not enough room. I think free air will be fine at 300-400hz filtering??

I can always space the main bracket out for more room inwards.

I managed to get one side done. Although the screws did split (I used 1/2" mdf and even used the cabinetry cone shape predrill bit) so I'm thinking that 2 L brackets with nuts, bolts and washers on the face will solve the issue.

I covered it with some felt I had laying around. Google said hot glue works...so I did that and it came out nice!

Next step...making a home audio style cover with black speaker grill cloth. I want to use those plastic/rubber inserts that let you take the grill off. Anyone know what those are called? Goal is to have them hidden from view when I roll the window down.

Alright they sound perfect outside but I didn't have enough room to give them a box. So the drivers side is the closest speaker to my ear. It overpowers every other speaker in the car.

Is there some way I can seal them up if I only have 1/8" behind them? Do I need to keep the vent pole clear or can I butt a piece of mdf right to it?

Thanks for the info. I will have to space the main bracket out so I can box them up properly then. For now I'll turn the gain down on their amp.
