LLJ Dash Tweeter adapters

Tweeter speaker adapters are a must have in car audio. Without them you go back to the days of reusing the factory Tweeter mount bracket, something that cant be done in modern vehicles do to the Tweeters being built into them and not having a lip to attaché the new speakers to. 

Our Tweeter adapters are built from acrylic and ABS designed to fit the most commonly found tweeter sizes on the market. Our OEM direct fit design means you don't need to modify any part of your vehicle for it to work.

What the experts say

Installed aftermarket sub and amp and was left with a loud hum noise. Simple plug and play ANC bypass harness completely eliminated the noise, crystal clear bass and I didn’t have to hack up the factory wiring

OMG !!! IT WORKS!!! THANK YOU LLJCUSTOMS!!!! This has been a long 4 year struggle ... The Dealer was done and thought i was hearing things (droning)
I installed the plug just 30 min's ago and took it for a ride the drone is gone!!!!!!!! YAYYY !

Installed in my 2018 Tahoe Premier RST after adding 2 12in kickers I had the most annoying hum in the speakers, this fixed it! Now it sounds wonderful! If you're Adding subs to your GM vehicle that has the Bose system with ANC I highly recommend this harness Best 20 bucks I ever spent!
