GMC Sierra Subwoofer Box
This customer brought us his 2015 GMC Sierra looking to upgrade the audio system because the factory system didn’t produce any quality sound. We took him to our demo room and let him listen to the great sound of JL Audio. We like the 8 inch amplified loaded subwoofer enclosure by JL Audio. He liked the look of it as well as the great sound. He had us go right ahead and install it along with a new set of Alpine component speakers and JL Audio 4 inch speakers. He chose an Alpine power pack to boost the sound quality. Upon completion the customer was very please and loved the new sound inside of his truck. This GMC Sierra subwoofer box and audio upgrade was professionally installed by the tech crew at Audio Express 5004 N. Oracle Rd, Tucson, AZ 85704 (520) 888-7066 your car audio installation experts.
