Sound Storm Laboratories LOPRO8 Amplified Subwoofer 600 Watts 2 in 1 accessory

SKU CH-RKQ9-2C5E5

Low-profile amplified subwoofer delivers 600 watts max power with built-in MOSFET amplifier for vehicles with limited space

  • Built-in amplifier with MOSFET supply delivers efficient power
  • Variable low-pass filter removes unwanted high frequencies from subwoofer output
  • High-level inputs connect directly to factory speaker wires
  • Low-level RCA inputs link cleanly to aftermarket head units
  • Remote subwoofer control adjusts bass level from the driver seat

Compact Amplified Subwoofer

The Sound Storm Laboratories LOPRO8 is a low-profile amplified subwoofer designed for vehicle audio systems where space is limited. Its shallow 3-inch height allows installation under seats or in tight cargo areas. The unit integrates a Class A/B amplifier with a MOSFET power supply for efficient power delivery. It suits drivers wanting stronger bass without sacrificing cabin space.

600 Watts Max Power

The single specification that determines suitability is the 600 Watts maximum power rating combined with the built-in amplifier. This integrated design eliminates the need for a separate external amplifier and complex wiring runs. High-level and low-level inputs provide compatibility with factory stereos and aftermarket head units alike. The MOSFET power supply improves switching performance for reliable output.

Handles Factory And Aftermarket Systems

The subwoofer comfortably handles integration with both factory radios lacking RCA outputs and aftermarket units with multiple pre-amp outputs. Variable low-pass crossover, bass boost, subsonic filter and phase control allow tuning for the vehicle interior. Remote subwoofer control enables level adjustment from the driver's seat. It runs out when the installation requires deeper enclosure depth or higher continuous power than the compact chassis can dissipate.

Questions about this item

What does the 600-watt maximum power rating mean for everyday listening?

The 600-watt peak rating indicates the highest short-term output the built-in amplifier can deliver during musical transients; continuous RMS power will be lower, so expect strong bass impact rather than sustained high-volume output at that level.

How do the high-level and low-level inputs affect connecting this subwoofer to my stereo?

High-level inputs let you tap into speaker wires from a factory radio without RCA outputs, while low-level RCA inputs connect directly to aftermarket head units; both options are provided so the LOPRO8 works with almost any in-dash stereo.

What physical space is required to mount this amplified subwoofer?

The enclosure measures only three inches in height, allowing it to slide under most vehicle seats or into other tight compartments where a traditional boxed subwoofer would not fit.
