Top Notch Product and Company

The block off plates are incredible! Definitely noticed the difference they make. On top of the great product, I called the business with a couple questions and they were the most down to earth and nicest people! Would order from SGS again!

Racks and Adapters

First of all excellent caring customer service. Regardless of the amount of purchase Don was extremely helpful and courteous. I absolutely loved the amp rack for behind the seat on my 2016 ford lariat. The door speaker mounts are the best you will ever find. Highly recommended

Fantastic quality

The wiring harness is high quality, cables are all wrapped properly, and ends feel sturdy. Made install so easy and straightforward. Add and amp rack and have everything plug and play. Very happy with my purchase.
Customer service was fast and efficient. Nothing to complain about at all

Perfect

The quality is outstanding and make all other products feel like garbage. It’s pricey but definitely durable without a doubt.

Perfect fit and absolutely necessary imo!

Fit as they should and are very well made. These along with the sound treatment make the doors a much more friendly environment for your speakers.

Super rigid HDPE! Perfect fit!

Can’t speak for all 6.5” speakers, but my Focal KX2 mid bass drivers and Flax Evo coaxials fit like a glove. Absolute necessity when upgrading speakers.

Perfect fit!

Super rigid. Used this to mount a Mosconi Pro 5/30 and 6to8 Aerospace, as the behind the seat rack wasn’t wide enough to accommodate the big 5/30. If looking at this as an option, be sure and get accurate measurements of the equipment you plan on using. As seen the photos, I had to make angled risers to give myself room to terminate all of the wiring on the 5/30. Still, this was the perfect solution for getting the 5/30 in while also having the stealth behind the seat enclosure installed.

Thoroughly impressed!

Like most, I was skeptical of how efficient and effective the two 6.5” subs would be. But, the factory sub wasn’t cutting it and I wanted to retain the factory under the seat storage. I’m powering this and my front stage with a Mosconi Pro 5/30 and these little fellas take everything you throw at them. My goal was SQ, and this was the perfect addition. Truly blown away at how low and how clean they play. If you’re building a system for SQ, you can’t go wrong with this enclosure.

Simple but necessary

Like everything else I’ve ordered from SGS, this was of high quality and shipped to my door quickly. Absolutely necessary when removing the factory “infinite baffle” sub.

T-Harness for BOSE with FOCAL LOC

This component is plug-n-play, simple to install, and I am impressed by the output signal level and clarity. It is a must have for those who want to retain the factory BOSE amplifier while adding an aftermarket amplifier and subwoofers.
