JBL Audio Stadium GTO620 Stadium Series
One of our favourite moments during a car audio installation is pulling out an old, ragged factory speaker from its location and then picking up its new, aftermarket replacement. And if you’re installing JBL Audio Stadium GTO620 premium car speakers, the immediate difference is a dramatic jump in design and build. From the hefty magnet to the oversized voice coil with shimmering copper, you can see and feel improvement — now just imagine how much better they’ll sound than the browning antiques that have been filling your ears with compromised audio for so long.
