This Triumph TR6 already had an aftermarket sound system installed several decades ago with a Kenwood cassette deck and a 4-speaker system. The speakers were starting to sound worn out and the car lacked any real modern use with such an outdated head unit. We installed a full Alpine sound system to update this classic.
The Alpine UTE-73BT head unit offers the bluetooth connectivity needed to stream music and take handsfree calls. It also has a USB port built into the faceplate which is great for charging phones. These vehicles did not come with factory 12V outlets so the USB port is a nice feature.
With the speakers, we reused the front Kenwood grilles as the Alpines did not come with any. We also added a subwoofer behind the passenger seat. This sealed 8" unit offers 120W which is plenty in such a small open vehicle. The rear speaker positioning is a little odd as they tend to overpower the front speakers which are by the driver's knee. Both speakers are coaxial units meaning they have silk dome tweeters mounted in-line for better sound reproduction. We did not have to drill any new holes or modify the old setup much.
Parts Used:
- Alpine UTE-73BT (Mechless Bluetooth Head Unit)
- Alpine S-S40 (Front 4" Coaxial Speakers)
- Alpine S-S50 (Rear parcel shelf 5.25" Coaxial speakers)
- Alpine PWE-S8 (Powered 8" Subwoofer)
