The THUNDER52 is a 5.25" 2-way coaxial speaker pair that can handle up to 45-watts RMS power. THUNDER speakers are set apart from the "other guys" because of its ability to reproduce low frequencies that other speakers cannot reproduce.
The THUNDER52 plays all the way down to 55Hz so even in systems that don't have subwoofers, you can get excellent bass response for all kinds of music.
Upgrading your factory speakers is one of the easiest ways to get better sound in your car. Aftermarket speakers are able to handle more power and use better materials to deliver a better listening experience. The TERMINATOR Series speakers are designed to improve factory sound and work even better with an aftermarket radio and external amplifier.
The TERMINATOR522 is a 5.25"coaxial speaker that is capable of handling up to 35W RMS power and has a 4 ohm impedance. The unit includes a durable steel basket, polypropylene cone, and mylar dome tweeter.
