Colossal Sounds Extreme Series β 750W RMS
The Colossal Sounds Extreme Series is the entry point into the Colossal subwoofer lineup. Extreme Series subwoofers are rated at 750 watts RMS and are designed around daily-driver performance with an emphasis on strong low-frequency output.
The Extreme platform uses a 2.5-inch round-wound copper voice coil, Y35 ferrite motor structure with triple stacked magnets, a non-pressed paper cone, carbon-fiber dust cap, progressive spider system and heavy-duty lead wires.
For customers who want a serious car audio subwoofer without immediately moving into a 2500- or 3500-watt driver, the Extreme Series provides a practical place to start.
Colossal Sounds Ultra Series β 2500W RMS
The Colossal Sounds Ultra Series steps into serious high-power car audio. Ultra Series subwoofers are rated at 2500 watts RMS and are designed for builders looking for considerably more output while still building a system intended for regular listening and demo use.
The Ultra platform features a 3-inch flat-wound four-layer voice coil, triple Y35 ferrite magnets, a non-pressed paper cone, carbon-fiber dust cap, dual-layer Nomex spider system, heavy-duty sewn-in lead wires and a cast-aluminum basket.
A 2500-watt RMS subwoofer system also requires more planning outside of the subwoofer itself. Amplifier power, final impedance, enclosure design, power wire, grounding, battery reserve and alternator output all become increasingly important as system power increases.
Colossal Sounds Mammoth Series β 3500W RMS
The Colossal Sounds Mammoth Series sits at the top of the current Colossal subwoofer lineup with a 3500-watt RMS rating.
Mammoth Series subwoofers use a 4-inch flat-wound four-layer voice coil, triple Y35 ferrite magnets, heavy-duty suspension components, multiple sewn-in lead wires and a cast-aluminum basket designed for high-power applications.
This is the series for customers planning serious high-output bass systems where the subwoofer, amplifier, enclosure and vehicle electrical system are all being built around substantial power.
Colossal Sounds and the Adire Audio KH Series
Car audio enthusiasts familiar with older Adire Audio KH Series subwoofers may recognize the connection to the current Colossal lineup.
Adire Audio's own discontinued product pages direct customers looking for replacements for certain KH Series models to Colossal Sounds products. Adire identifies the Colossal Extreme Series as the replacement direction for KH501 models, the Colossal Ultra Series for KH2501 models, and the Colossal Mammoth Series for KH3001 models.
That history makes Colossal especially interesting for bass enthusiasts who remember the Adire KH platform while giving today's builders current Colossal Sounds options across several different power levels.
Building a Complete Colossal Sounds Bass System
A subwoofer is only one part of a properly designed bass system. The enclosure, amplifier, final wired impedance, electrical support and installation all affect how the finished system performs.
When matching an amplifier to a Colossal Sounds subwoofer, compare the actual RMS power requirements and voice-coil configuration with the amplifier's RMS output at the final wired impedance. Browse our complete selection of car audio amplifiers when planning the system.
Power Wire & Installation Wiring
High-power amplifiers need properly sized power and ground cable, secure connections and appropriate fuse protection. Shop car audio power wire and speaker wire for complete system wiring.
Electrical Support
As amplifier demand increases, factory electrical systems can become a limiting factor. Depending on the vehicle and system power, a build may require upgraded wiring, additional battery reserve, a Big 3 upgrade, higher-output charging capability or a combination of upgrades.

Colossal Sounds FAQ
How much power do Colossal Sounds subwoofers handle?
The current Colossal Sounds lineup includes Extreme Series subwoofers rated at 750 watts RMS, Ultra Series subwoofers rated at 2500 watts RMS and Mammoth Series subwoofers rated at 3500 watts RMS. Always verify the specifications for the exact model before choosing an amplifier.
What is the difference between Colossal Extreme, Ultra and Mammoth?
The biggest difference is the intended power level and construction. Extreme is the lower-power daily-driver line, Ultra moves into 2500-watt RMS high-output systems, and Mammoth is the 3500-watt RMS high-power series.
Are Colossal Sounds subwoofers related to Adire Audio?
Adire Audio's own discontinued KH Series product pages identify current Colossal Sounds products as replacements for several former KH models. Adire directs KH501 customers toward the Colossal Extreme Series, KH2501 customers toward the Ultra Series and KH3001 customers toward the Mammoth Series.
Do I need upgraded electrical for a Colossal Sounds subwoofer?
That depends primarily on the amplifier powering the subwoofer, the vehicle's factory charging system and how the system will be used. Higher-power Ultra and Mammoth builds can place significant demand on the electrical system and may require upgraded wiring, battery capacity, Big 3 wiring or a high-output alternator.
What amplifier should I use with a Colossal Sounds subwoofer?
Choose the amplifier according to the exact subwoofer model, quantity of subwoofers, voice-coil configuration, final wired impedance and RMS power requirements. Do not match equipment using maximum or peak wattage ratings.
Does enclosure design matter?
Absolutely. Airspace, tuning frequency, port area, mounting depth and subwoofer displacement can all affect performance. Always build or select an enclosure around the specifications of the exact Colossal Sounds model being installed.
