Product Description
The MGA is one of the prettiest shapes ever to come out of Abingdon, and owners tend to be careful about anything that changes the look of the cockpit. That is exactly why the radio is such a tricky decision. Keeping an original set means living with weak reception and no way to play your own music. Fitting a typical modern stereo means a glowing plastic box that looks wrong the moment you sit down. The KHE-300-USB with Bluetooth for MGA sits between those two choices.
This radio is part of the KHE-300 line from Ken Harrison, a range designed specifically for vintage vehicles. The MGA version is intended to fit the original dash opening, so you get modern listening features while keeping a period-style face in the car.
What the KHE-300 Gives You
The KHE series owner's manual and this radio's feature list describe a well-equipped unit for its size:
- Built-in Bluetooth for wireless music streaming
- Front USB port for MP3 files on a USB drive or player
- Front mini SD card slot
- Electronically tuned PLL synthesized AM/FM tuner
- 12 presets in total, 6 AM and 6 FM
- Seek, auto scan, preset scan and auto store functions
- Manual up/down tuning
- Separate bass and treble controls with a front/rear fader
- LCD display with clock
- RCA pre-outs, rear auxiliary input and an auto antenna power lead
- 200 watts of system power (50 watts x 4)
For a car like the MGA, which is often driven on weekends, at club runs and on long summer tours, that flexibility matters. You can load a USB stick or SD card with hours of music and leave it in the radio, stream a podcast or navigation prompts from your phone, or listen to the ball game on AM.
Keeping the Cockpit Looking Right
A big part of the appeal is what the KHE-300 does not do. It does not ask you to cut the dash, and it does not fill the center of the car with a modern-looking faceplate. Its classic face and buttons blend in with the MGA's simple instruments and switches, which makes it a good choice for owners who show their cars or simply care about originality.
Building a Complete System
An MGA has limited space for speakers, so it pays to plan the whole system at once. The options above let you add a front dual voice coil speaker, which carries both stereo channels through a single speaker, so you still hear the full stereo mix from one mounting position. You can also add a rear 6x9 pair, either the Custom Autosound 6x9 speakers or an upgraded Pioneer pair, if your car has a suitable location for them. A hideaway antenna is also offered, which avoids drilling a hole for a traditional mast.
Before You Install
Many classic British cars were built with positive ground electrical systems, and some have since been converted to negative ground. Check how your MGA is wired before connecting any modern electronics, because this matters for every 12-volt negative ground accessory. Ken Harrison's manual suggests having the radio installed by an auto radio specialist. Vintage Car Radio sells the radio and accessories only and does not offer installation, but we are happy to answer questions before you order.
