Exceeded My Expectations

These front door block off plates were exactly what I wanted and needed. Anyone with a Tundra knows that it’s difficult to get good mid bass from Tundra doors.. This was the final piece I needed to get my mids where I wanted them. I only ordered the front plates just to make sure they were what I needed. They exceeded my expectations and will be ordering them for my rear doors now.

Nice fit, very cool logo

Very good sound, clear, loud and lots of Bass

Sound Good Stereo tops the list for your go car audio needs

I purchased an amp rack and block off plates for my truck and was VERY pleased with how well each item was made. The amp rack comes with all the hardware required for assembly. The block off plates are a must have for sound reduction. SGS's plates are well made and come with the screws required for a perfect install.

Beautiful fits great

Block off plates

When installed and using sound deadening this made a world of difference in mid-bass response. Great fit.

No brainer!

I debated making my own amp rack but decided to try this based on other reviews…and I’m glad I did! The fit and finish is outstanding. The plastic is 1/2 thick and very sturdy. I was a bit skeptical that it would be loose since it only has one bolt to positively retain it. But rest assure this thing doesn’t go anywhere. This is a no brainer!

Amazing product

I happened to come across this amp rack from a YouTube video and decided that it would make my life easier and look much more professional.
Even though I was only adding a subwoofer amplifier and a LC2i line out converter I wanted a clean look without the hassle of making my own.
I am totally pleased of well it fit. Every existing bolt hole aligns perfectly and it even has the holes predrilled with screws to move the Bose amp and other electronics. The trucks harness is long enough to just move the existing stuff outward leaving plenty of room in the middle for new equipment.

Truly plug & play..

Used on my 2022 gmc sierra refresh with Bose system. Harness was well built and high quality. .

Awesome!

Fast shipping. Great quality. Thanks a lot.
