With 4 volts of signal from the preamp level RCA outputs, audio systems can be designed to integrate external amplifiers for speakers and subwoofers.

Choose from several types of amplifiers in the MB Quart line of marine, off-road and mobile amplifiers. The compact NA2 line-up is ideal for power density and efficiency, which means a small installation footprint in your RV and maximum power output. Also consider the full marine line of amplifiers and many choices of MB Quart car audio amplifiers.

For speakers and subwoofers, consider if you wish to have speakers hidden away into original locations or more outdoor and off road options. Check out the full line of MB Quart Nautic Speakers and Tower Speakers or more traditional car audio speakers, such as those you might install within an RV interior.

Of course the heart of music is hidden in the bass frequencies, which means subwoofers. MB Quart has that covered with waterproof Nautic and car audio subwoofers that provide incredible low frequency performance in very moderate air space requirements.
