The SoundSkins Sound Quality Speaker Kit 4 Door Bundle treats every door speaker in your car in one order. It includes two complete Sound Quality Speaker Kits, enough to seal, isolate and deaden four speaker locations, front and rear, for 20% less than buying the kits separately. Whether you are running factory speakers or a full aftermarket upgrade, every speaker in the car gets the same treatment, so the whole system sounds tighter, clearer and more balanced.

Why Treat the Rear Speakers Too?
Most people upgrade or treat the front speakers and leave the rears alone. The result is a system that sounds clean up front but thin and buzzy behind you. Treating all four locations gives you:
-
A balanced sound across the cabin: Front and rear speakers produce the same tight mid-bass, so rear passengers get the same quality you do.
-
No rattles from the back: Rear door panels are often the first to buzz when the volume goes up. Sealing and deadening them stops it.
-
More mid-bass overall: Four sealed speakers push more usable bass into the cabin than two treated and two leaking into the doors.
-
One consistent install: Every door gets the same parts, so the whole system is tuned the same way.
How the Kit Works at Each Door
At every speaker location, the foam ring seals the speaker to the door panel, the backing sheet absorbs the rear sound wave inside the door, the SoundSkins Pro sheet deadens the metal around the speaker and the gasket tape stops buzzing at the mount. For a detailed breakdown of each part, see the Sound Quality Speaker Kit.
Planning a Four-Door Install
-
Work one door at a time so you always have a finished door to copy.
-
Split the parts per door: 1 foam ring, 1 backing sheet and 1 Speaker Kit Sheet per speaker. Each 3' roll of gasket tape covers two speakers.
-
Check the rear speaker size before cutting the foam rings. Many cars use smaller speakers in the rear doors, so cut each ring to fit.
-
Clean the metal with isopropyl alcohol before applying the backing and Speaker Kit Sheets.
Want to go further? Add the SoundSkins Pro 4 Door Kit to deaden every door completely, for a quieter cabin and even more mid-bass.
Frequently Asked Questions
What is the difference between this bundle and the single kit?
The single kit treats two speakers. This bundle includes two complete kits to treat four speakers, and costs $23.60 less than buying two single kits.
My rear speakers are smaller than my fronts. Will it still work?
Yes. The foam rings are strips you cut to length, so they fit smaller rear speakers as well as 6.5" and 6x9 fronts.
Does it work with factory speakers?
Yes. It treats the door around each speaker, so it improves factory and aftermarket speakers alike.
Do I need special tools?
No. Every part is peel and stick. You only need the tools to remove your door panels and speakers, plus a knife or scissors to trim the foam.
