If you want speakers that'll make the most out of the power they're given, JBL's GT6 Series speakers are a smart way to go. They're sensitive enough to perk up the sound of a factory radio, but tough enough to handle an outboard amplifier too. These JBLs will impress you with their powerful bass, clear highs, and strong output.
Oversized cones, powerful tweeters
The GT6-5 2-way speakers employ 5-1/4" Plus One polypropylene woofer cones — with 30% more surface area than most other 5-1/4" speakers — to dish out the lows with accuracy and strength. The vented motor design keeps the speaker cool and operating efficiently when you've got the volume cranked. Each 1" titanium-laminate tweeter projects highs that'll sparkle over the sound of road and wind noise.
