JBL Stadium GTO620 6.5" 2-Way Speakers
-----------------------------------------------------------------------------------------------
Say goodbye to factory sound
One of my favorite 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's 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.

Edge-driven dome tweeters
JBL created their GTO620 6-1/2" speakers as a hi-fi solution for those who want better sound in their vehicle. You'll find an edge-driven design in their PEI polymer dome tweeters for a smoother, more open response and minimal distortion at high volume levels. Each tweeter also features a level control button so you can adjust the brightness to your taste.

Woofers enhanced with Plus One+ technology
JBL's glass fiber woofer will hold its shape when the power's cranked up, so you still get punchy and defined bass. Glass fiber weighs less than traditional materials, so you don't need a ton of power to drive this woofer either. JBL's Plus One+ woofer technology extends the cone right up to the edge of the basket, giving you lots of surface area — and a bigger cone means more bass to complement the superior high-frequency response.

Power handling perfect for any system
These 2.5-ohm speakers boast ultra-high sensitivity so that you can power them with a factory radio or aftermarket stereo, but you'll get your best results feeding them plenty of power from an outboard amp. Either way, these speakers' low impedance safely takes advantage of every watt of power available for exceptional performance. Grilles are included.
