Check out this 2014 GMC Sierra we just finished up!
This customer already had his gear and reached out to us to handle the install — and we got him taken care of 👌
Even though we prefer to install equipment we sell, we do work with customer-supplied equipment when we can 👍
🔊 System Details:
• (2) Skar 8” Subwoofers
• Skar Underseat Sub Box
• Skar 1200 Watt Amplifier
• Custom Amp Rack fabricated in-house at Flewellyn’s Performance
We mounted everything clean, built a solid amp rack, and wired it all up nice, neat, and serviceable — no spaghetti messes here 🧼🔧
Now this Sierra has the low end to match the truck 😎
Ready to cruise and turn up the tunes 🎶💪
If you’ve got equipment already and need a professional install, or want a full system built from the ground up, we’ve got you covered.
