These particular speakers are Boston Acoustics RC61 2-way component speakers..the woofer is 6 1/2", and the 1" tweeters are up under the dash grilles. They handle up to a rated 100 watts continuous power, so they'll take plenty. Just installed an identical set in my brother's car, driven by a 75W/ch Alpine V12 amp. They are absolutely unbelievable sounding!!! He's gonna do the exact same setup in his wife's car, a '99 New Beetle because he's so thrilled. I've gotta say, with a single 10" JL Audio with 300watts going to it, overall it's quite an unbelievable setup!
