12-Inch 250W RMS Subwoofer

The MTX 3512-04 is a 12-inch single voice coil subwoofer rated at 250 watts RMS with a 4 Ohm impedance. It belongs to the 35 Series and uses a polypropylene cone with an Inverted Apex surround. The design targets high sound pressure levels and low distortion for car audio systems.

Ideal for Bass Upgrades in Standard Enclosures

This subwoofer suits owners wanting louder, cleaner bass without a large box. Its low-profile design fits most vehicles and works with amplifiers delivering 125 to 250 watts RMS. Buyers needing higher power handling or dual voice coil wiring options should consider other models.

4 Ohm Impedance Defines Amplifier Match

The fixed 4 Ohm load determines which amplifiers can drive the woofer safely and efficiently. An amp stable at 4 Ohms and rated between 125 and 250 watts RMS is required for proper performance.

Questions about this item

What size enclosure does the 12" MTX 3512-04 require?

The subwoofer is designed for a low-profile enclosure that does not need a large internal volume, making it suitable for most vehicle installations.

How do I wire the single 4 Ohm voice coil to my amplifier?

Connect the positive and negative terminals directly to a matching 4 Ohm stable amplifier channel rated between 125 and 250 watts RMS.

How does the Spider Plateau Venting keep the voice coil cool over time?

The venting directs cool air straight at the voice coil during cone movement, managing temperature for sustained performance during extended use.
