309 Custom Audio - Monmouth, Illinois

I was looking to upgrade my Hertz system on my 2022 SGS as I wanted more bass, volume and balance. I was looking for a shop that could do more than just sell me new speakers and an amp. After talking to them about what I had and what I was looking for, they made several suggestions. After a few discussions, I decided to go with their recommendation to improve what I had rather than start over. I made a three-hour drive there and WOW, what a great decision. They upgraded my faring speakers to GZCF165NEO-PRO 6.5 with a Sound Digital 800.4 amp. They used the 4 channels in the fairing for the two speakers and ran separate channels for the mid woofers and tweeters. They also added a second DS800.4 and bridged it to my existing Hertz 690Neo 6x9 lid speakers and added a HKI Mini DSP along with an amp rack. The tuning they did was amazing and I can't believe the volume, bass, balance, and clarity. They upgraded my power supply wiring and battery as well. Since it was there, they also did some other service work. This is a veteran owned business that I would highly recommend. They are well worth the trip. Thanks for the great system.

Sent a message on a Saturday afternoon after the shop was closed looking for information on their fairing shroud. They emailed me back almost immediately. Sent me an invoice first thing Monday morning, and I received the shroud on Thursday. You can't ask for better customer service!

Thanks guys!

And for anyone thinking about not using this shroud when installing equipment in your fairings. Stop, order it. Protect your investment! It's perfectly cut and dyed for your mounting holes. Quick simple affordable piece of mind.

Just placed a new order for more of the 309's shrouds. And once again. The customer service is unparalleled. These guys are on spot and every bike out there with equipment in the fairing should have one of their shrouds. Protect your investment.

I highly recommend 309 Custom Audio and Chris Perdue reason being I am about 12 hours away from him but he has help me redesign the hole audio for my motorcycle. Whether it’s on the phone talking to me about what I need on through Facebook messenger looking at my layout on how I want or need to do it. He has helped me when no one else really wanted too. I have ordered some parts from him for this build but he didn’t even ask me to do that he just decided to help and for that I want to say thanks and you are forever a brother to me. Highly recommend them and him.

Top notch guys and they’re very very helpful and good at what they do. Had my lids modified (5x7 to 6x9) for a cicada system they done a great job and answered all my questions. I’ll definitely be back to get the stereo tuned once I get it installed and the weather breaks. Once again thank you very much. If you want it done rite go to 309 Custom audio and they will take care of you!
