A lot of classic cars – including the classic Mustangs – have a center dash location for a single dash speaker. If you want stereo output from a single speaker location, you need a Dual Voice Coil (DVC) speaker.
Read on to find out everything you need about DVC speakers and how to choose the right dual voice coil speaker for your classic car.
Until recently, my 65 Mustang had only two speakers, located in the rear. As I usually drive it all by my lonesome, this never felt like an issue – just crank up the volume and the sound is just fine.
A recent road trip with 3 passengers changed my mind however. Imagine driving a carburetted 289 V8 with the windows open. Now imagine trying to hear the music from those rear speakers over that engine’s mighty roar. Now factor in the two people in the back seat! Recipe for disaster.
The search for a single stereo speaker
Unless you’re willing to cut holes into the two front quarter panels to mount left and right at the front, you’re pretty much limited to the single center dash speaker location.
When I got my car, this space was taken by two tiny cardboard speakers, yielding a terrifying 5W each.
A search for replacement speakers quickly revealed that the available space limits you to very small and underwhelming replacement speakers.
At which point, you discover Dual Voice Coil speakers! A DVC speaker has two inputs so you can connect both right and left stereo channels from your car radio to a single speaker. This makes it an ideal solution for classic cars with a single speaker position in the dashboard.
What’s the difference with a standard Single Voice Coil speaker?
Any standard speaker is Single Voice Coil (SVC), which means you need two speakers for a stereo setup.
A dual voice coil setup allows a single speaker to create a stereo sound. There is really no loss of quality – connecting both stereo channels to a single speakers creates a richer, fuller sound then a single ‘mono’ speaker is able to provide.
I opted for the R-410N DVC speaker from RetroSound. And now I blast stereo in the front as well as in the back!
