Best brackets money can buy!

I've been a loyal customer of SGS for a couple years now. Everything they make is top quality. These brackets I've purchased for my last two vehicles. Expensive, but you get what you pay for. Noone does it better.

I had previously ordered audio equipment from another place which included a very cheap set of speaker adapters, free. There is a reason those were free. I kept looking and found Soundsgoodstereo and their vehicle specific adapters. Perfect match and solid built. It’s exactly what I was looking for. Thank you.

Great Investment for your audio system.

Great quality comes with everything you need for a flawless installation. I highly recommend these adapters. Don't cheat yourself with those cheap plastic ones get the good stuff.

Hella good speaker adaptor’s

You won’t regret mounting your high powered expensive speakers with these rings. If you didn’t skimp on your equipment why skimp on necessary install hardware? It doesn’t make sense to me. These speaker adaptors are excellent, get them!!

19 Chevy Tahoe

Had the client order the front 8" kit for his Tahoe. Swapped the left and right brackets for fitment. Added a 1/8" spacer to them and took a rabbeting bit to give slightly more room for the 8" Def Bonce and it dropped right in. Only other modification was to the seat memory switch. Built a little platform for it to sit into. Besides that they were great

Nice Brackets

These 6.5” speakers Brackets worked great in my 2013 Chevy Tahoe. I lined the back with Dynaliner 1/8" thick, to reduce vibration. Also, paired with NVX Speaker Baffles. Items fit perfectly with no modifications.. thank you!

Product Description

Machined from a full 1-inch sheet of solid-core virgin HDPE - one of the most expensive plastics to work with for speaker adapters, and also the best. At this thickness, the adapter provides the mounting depth larger drivers need while eliminating the flex and resonance that thinner adapters introduce at high output levels.

The factory 6x9 front speaker mounting in these trucks is one of the most common upgrade targets in car audio. We designed these adapters to convert that location to accept 6.5-inch, 6x9-inch, or 8-inch aftermarket drivers. Rear door adapters are also available for a full cabin upgrade. Every variant includes its own product photo so you can see exactly what you are ordering.

Available as a Complete Kit with plug-and-play wire harnesses, foam gaskets with 3M adhesive, sound treatment, and all hardware - or Adapters Only if you already have your wiring sorted. Works with both Bose and non-Bose equipped trucks.
