    I went to Systems Unlimited to install a dashcam/rear camera in my 2018 Honda Civic Type R and in my 2021 Dodge Challenger. They did an incredible job. Each set of cameras were installed in one day, they explained the process to me, confirmed exactly where I'd like them placed, and explained the system to me when I picked up my car(s). Very professional job with clear attention to detail. I checked things over carefully at home and everything was seamlessly installed. Everyone I worked with was very helpful and clearly take pride in their work. Would highly recommend!

    I've done a horrible disservice to Charles and the crew by not leaving a review mush sooner. Back in June of 2023, I had the need to drive my 1985 Porsche 911 1200 miles and back, for a large PCA event. I just couldn't do it listening to the garbage sound quality. I've struggled to get any sort of low end bass at all out of this car since 2007, so I took it to Systems Unlimited. They custom-built a small subwoofer enclosure that fit perfectly in place behind the passenger seat, installed an Audison DSP amplifier under the seat, cleaned up the wiring issues of an ancient A/D/S amplifier install, and dropped in a new bluetooth single-din head unit, as well. They added some sound deadening and weatherproofing to the doors, and even repaired a cracked door-pocket. The workmanship is immaculate, and the sound quality has been transformed into something amazing. This car is now truly a pleasure to drive. Thank you, Charles and crew!

    This is the only place I will allow to touch my vehicle. Systems Unlimited provided one of the best customer experiences I have ever had. Charles and his team offered full transparency through the entire process. I was able to see the wiring and thought process behind every decision in real time. (I have never seen a cleaner wiring job). I did a full Audison system, I have had plenty of audio systems that I considered high end. Boy was I wrong. The combination sound deadening, audison speakers and amp with DSP as well as custom box with 5 subs has proven to be a perfect system. My 992 Targa now has a symphony in it at all times. When I received the car back there was zero traces that everything had been replaced (other then the sub box that somehow looks factory Porsche). They somehow tucked a sub box in a spot that sits beneath the Targa top when folded down. Also custom printed mounts for door speakers and wiring. Crazy stuff happening in that shop. I cant imagine a job they couldnt handle. I wish I found these guys sooner.

    I had two Escort radar-laser systems as well as a high end Audio installed at another shop. I contacted Systems Unlimited to up grade my radar-laser system to a Radenso Ultimate Edition. While my 2014 Porsche 911 Carrera S Cabriolet was in the shop, I experienced a sound system in another 911 they had done and chose to upgrade my audio system as well! For those seeking over the top Craft and Workmanship on custom car stereo and radar-laser defense. Systems Unlimited is the Best! From disassembly to install every nut, bolt, screw, was put in place and the work looks like it was Factory installed. You would not know the upgraded system until you Hear, Feel, and Experience it for yourself. It is AWSOME! The Professional Custom Installers and owner Charles are hands on from beginning to the end of project. No project is too big or small and he will work with your price point. Charles will follow up to make sure your custom install is working without issues. A Very Satisfied Customer!

    I purchased a 2021 RAV4 Prime in July and I wanted to get it sound damped to make the ride a little quieter. I called and spoke with Charles. He invited me down to the shop to see the type of sound damping they offer. Charles was very accommodating and before I left, I took a listen to the sound system in his car. It had been a few cars since I had a custom system (Zapco) and decided to go ahead and upgrade the audio at the same time. The original plan was to keep my existing drivers, replace the factory JBL amp with an Arc Audio 8-channel DSP amp and a second amp for the subwoofer. He also wanted to find a way to re-enforce the JBL sub enclosure, which is plastic. At some point he asked if we could replace the spare tire with a custom subwoofer enclosure and then we could use a larger sub and / or two subs, which we ended up doing. The one issue I was stuck on is that we would only have 8-channels of DSP, so the rear fill would be mono and we could not time align them individually. I up-sold myself on using two Arc Audio 1000-watt DSP amps. A 6-channel DSP for the front speakers (Door, Dash and A-Pillar) and a 4-channel DSP amp for the rear fill and then bridge the other two channels for the dual subs. Given the new power from the larger amps, Charles upgraded all of the stock drivers with new ones from Morel because the factory could not handle the power. In fact, the factory Amp/Sub limits the sub output, which the new system is not limited by. While I was visiting family, Charles arranged for Brian Mitchel, from Arc Audio, to re-calibrate my sound system. Brian wins a lot of the audio competitions and he calibrated my vehicle like his competition vehicle and I could not be happier with the results. While my Prime was being worked on, I found other upgrades I wanted to do and imported some parts from Japan, including TRD Performance Dampers, TRD Door Stabilizers, a Strut Tower Bar, LED lighting, etc I asked Charles if he could have his team install all of this and bill me and he was very accommodating. I am planning to go back to Systems Unlimited later this year to have some more work done, their attention to detail is second to none. It was not cheap, but I feel this is a case of you get what you pay for. They do immaculate work and I could not be happier with the results! Went back for some additional work in September of 2020. Wanted a custom cargo floor to show off the amps and to vent the heat from that area. Also had a throttle controller and Scan Gauge III I wanted installed with a custom faceplate. Photos attached. As usual, excellent work that is second to none.
