Pairings:
- A single Spike Series 4 ohm subwoofer pairs handsomely with the ACM-2.300 or ACX-300.2 amplifiers for conservative to moderate listeners. For more robust output levels, consider the LC-1.800.
- LC-5.1300 or D-5.1300 amplifiers provide ample power, with channel 5 being an excellent match.
- For systems with two Spike Series 4 ohm subwoofers, LC-1.800 is recommended.
- Consult an expert for configurations with three or more subwoofers.
