About the Kicker 49ST3TW
From our tech experts at CEN
Tweeters handling 50w RMS for adding high-frequency detail where the factory system has none, or for replacing tweeters in an existing component set.
Who it suits
Drivers whose system sounds dull at the top, and anyone building a front stage where the tweeter needs mounting on the pillar or dash rather than down in the door.
Our tech experts advise
Placement and aiming change the sound more than the tweeter itself, and they need crossing over properly so they are not asked to play too low. get in touch if you are unsure how they would integrate with your speakers. See car audio installation.
