Improve Sound. Your tunes sound better than ever with Boom Mat's 6x9" Oval Slim Speaker Baffles. This pair increases sound clarity by improving frequency response with its polyethylene material, while also lowering reverberation from door panels for better acoustics. You also won't hear as much road noise cruising in your 1999-2025 GMC Sierra.
Closed-Cell Polyethylene. Boom Mat constructs the two 6x9" Speaker Baffles from closed-cell polyethylene foam that is water-tight to prevent any moisture damage. This thin material picks out correct frequency responses and dampens reverberation that can happen in sheet metal for better acoustic resonance within your Sierra 1500. With its slim, oval shape, it also fits like a glove around your existing speaker for a custom look.
Easy to Install. These Oval Slim Speaker Baffles are a cinch to install around your interior speakers. The thin material conforms to tight areas, giving your friends the impression that you had a professional installation.
Application. This pair of Boom Mat 6x9" Oval Slim Speaker Baffles is designed for 1999-2025 GMC Sierra 1500s.
