Has your factory radio seen batter days? Is the dealership trying to charge you thousands for a new unit? Were able to repair a lot of factory radios for much cheaper than a new unit direct from the OEM. Give us a call to see what we can do to keep your music going without breaking the bank

Cadillac Eldorado and an Oldsmobile Cutlass in the bay this week for some audio upgrades!

2024 Lamborghini Huracan Evo Technica in the bay for a dash camera, GPS tracker and radar detector to help protect this customers investment. We were able to complete the installation without splicing a single wire to help make sure the vehicle can easily be reverted back to perfect stock condition if the owner ever chooses to sell it

We knew we had to do nothing less than something excellent for this Gallardo. It already had a Kenwood amplifier so we rewired it to utilize Full active crossovers on a set of Digital Designs C series components. This brought the sonic quality this Lamborghini deserved. The Pioneer made this easy with the built in network mode

R33GTS-T in the bay! We fitted out this JDM beauty with a custom trunk setup, underglow, interior and engine bay lighting, big 3 charging upgrade, new battery and a high output alternator. In the trunk is a Digital Designs SL710 with an SS5.500 powering all the speakers and subwoofer. It’s hard to describe the blessing it is to get to work on one of my dream cars

We have been super busy building a lot of custom enclosures lately! Sometimes prefabricated boxes are great but to get the best output out of a subwoofer there’s nothing like a properly designed box

1971 C10 needed some audio upgrade while still retaining the factory look as much as possible with minimal modifications. We got the job done with a Retrosound radio Digital Designs D series speakers and we were even able to retain his old school equalizer that was previously installed in the vehicle. Old school looks with new school quality!

Sometimes an 18” just isn’t enough.
For this Type R build, the goal was simple, create a serious SPL monster. We stepped it up with a Digital Designs 21” 9900 series woofer designed to move some serious air, backed by 3000 watts from a DD SS3000 amplifier.
To keep everything running strong, we upgraded the charging system with a high performance battery and completed the Big 3 upgrade, ensuring consistent power delivery even at full tilt.
And because no build is complete without style, we added underglow lighting using proven PMR lighting kits to finish it off right.
This setup hits hard, as long as the Type R’s back window can handle the pressure.

TF Mobile Tinting brought his boat by to get the system updated before he takes it out this spring. We replaced all the 20 year old speakers with Digital Designs D series speakers powered by an SX4.1000 and added 2 Triton Audio 10” marine subwoofers powered by a Triton PS1000.1. The clarity the DD speakers deliver and the power the Triton subs add to system are nothing less than impressive

Did you know we’re also a dealer for Rockford Fosgate? The owner of this wanted something that could be heard over the sound of the cammed 6.0 that was swapped into his 67 Camaro. So we cleaned up the old wiring and put in a Pioneer DMH4220 to a Digital Designs SS4.500 powering the 4 Rockford Punch and Prime speakers
