MTX's Road Thunder subs dish out heavy-hitting bass in your ride, perfect for filling out rock, R&B, jazz, classical, or anything else on your playlist. The RTS15-04 sub features a 15" polypropylene cone supported by a big rubber surround that resists cracking or separating. The sub's cooling system features forced-air venting in the stamped solid-steel frame that keeps the voice coil cool.
The uniquely shaped spider assembly and extended pole piece ensure linear cone movement, so your bass sounds full, deep, and clean. MTX optimizes this Road Thunder sub for sealed, ported, and bandpass enclosures so you can choose the type of bass you want in your ride.
To drive this single subwoofer, we recommend a mono amplifier rated between 225 and 450 watts RMS at 4 ohms. For more information, please refer to our article on How to Match Subwoofers and Amplifiers.
