2015 Dash Speaker Upgrade -- Simple Solution (Non-JBL with Nav)

[salong53]

What kind of foam are you guys using to back your speakers? I looked at speaker baffles, but I've read those can actually create a suction on the back side of the speaker and reduce its performance. I ordered the Infinity REF-3022cfx, and saw no mention of foam being included in the packaging.

I've considered some adhesive backed foam weatherstrip that is meant for insulation around doors/windows? Would this do the trick?

I did not use foam on mine and they sound great and have been fine. I did need to run bass blockers though, I was getting some very noticeable cutting out and distortion.

--Any foam will do, packing, weatherstripping, etc. But some types may deteriorate inside the automotive environment (check it in a year). Weatherstripping will work, but I would avoid the adhesive type, maybe buy a larger size and cut off the sticky part.
--It does not have to be all that neatly done. Just place it around the speaker basket. No need to pack the rear of the speaker.
--The idea is to prevent the out-of-phase waves generated from the back of the speaker from reaching the front.
--There will be no suction. The back of the speakers are open to the cabin and the back-pressure will be nearly nil. These small speaker cones don't move much when they are properly crossed-over.
--The factory speakers have a lip around the speaker grill that helps prevent back waves. One may have to cut that down to fit the new speaker as it may press against it, removing as little as possible will help.
