Key Specs
If you have a powerful amplifier in your car already, as is sometimes the case with factory upgrade systems in higher-end trim versions, then this quartet of speakers can help improve the “punch” of your sound. Rockford Fosgate is justifiably legendary for building rock-music-oriented automotive amps and speakers; these four are designed to be used with a high-power amp.
To get a full-spectrum upgrade, you’ll want to add a subwoofer and tweeters, but for owners of economy cars and small crossovers, many of which come with four 6.5-inch door speakers as standard, this should be a noticeable and welcome change.
