86 Sierra, 6x9s in factory rear brackets? No problem! Dynomat? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

lbrowne · 06-21-2018, 12:13 PM

Bit of a hack job but I got my Pioneer 6x9s into the factory corner 4x10 brackets. It will do for now until I get a better setup. Didn't have to flip and reverse the cab corners of the brackets - I drive with the seat all the way back and it doesn't touch the speakers.

My question is, I seem to be losing some sound volume/fill down into the cab corners. Anyone make a pocket or dynomat the back area of the speakers? That cardboard tray I think needs to go lol

Those brackets are eventually what I'll get to, with shipping etc to Canada it's a bit too much for me right now (no issue with the price, just not in the budget at this point)

So you just dynomat'd the pocket where you could reach?

Mine had nothing to begin with, so I just did all the rear cab wall and the corners (well floos too)

I put the FatMat on my back wall, and also stuffed some of that blue denim insulation up in the corners, behind the speakers. I also have the cardboard tray and put speaker carpet on it, and the original speaker brackets.

Your Welcome.

I was just looking around at USA1 Industries, and found a new product. If you want to lose the cardboard tray, which BTW this place has new ones.

I just installed one of the carpets. It goes all the way to the glass and fits the contour of the back wall very well. I got it from OC Carpets. I think it was a little cheaper.

You could try Boom Mat speakers baffles 6x9 #050380 made by DEI ( pair).They go on the back of the speakers oval (10-1/2" W x 7-3/4" H x 4-1/2" D
