FOR BETTER SOUND:
The MB Quart speakers came with crossovers. A crossover is a device that restricts and separates the range of frequencies sent to the speaker. I mounted four crossovers (one per speaker), in the trunk near the amp for easier connection. Connect each speaker’s woofer and tweeter (+/-) terminals to the corresponding OUTPUT terminals on the crossover. Now connect the amp’s output terminals to the INPUT on each of the crossovers. It might sound complicated, but if you follow the manufactures’ instructions carefully, the improvement in sound is well worth the time, labor and extra speaker wire. After the wires are routed, speakers are mounted and the subwoofer is in place, follow the diagram provided with the amp for the correct hook up.
