For multi-sub builds, the Kicker LX 51LX3000.1 and Warhorse 49WXA3600.1 go up to 3,000 and 3,600 watts at 1 ohm. Match the amp to your sub's impedance and power.
A mono amp, also called a monoblock, puts all its power into one channel made for a subwoofer. Most have a low-pass filter, a subsonic filter and bass boost, and many take speaker-level signal so they work with a factory radio.
Every amp here is on our listings. We install amps in our own bay at 22025 S Avalon Blvd Ste A.
This table is built only from our own product listings. Where a listing does not state a spec, the cell says so instead of guessing.
A mono amp makes more power at lower impedance. How the sub's voice coils are wired decides which column applies, so match the amp to the sub before you buy.
Mono subwoofer amplifiers compared, from our product listings. RMS power as each maker rates it. "Not in our listing" means our product page does not state that spec, so ask us before you count on it.

The JBL Club A600 make 600 W at 2 ohms, is an IP66 pack at 300 W for open vehicles.
The Kicker LX 51LX3000.1 makes 3,000 W at 1 ohm with FIT+ inputs up to 40 volts and RGB lighting.
The Kicker Warhorse 49WXA3600.1 is the biggest at 3,600 W at 1 ohm, with a competition mode. Its listing notes an amp at this level needs a battery and charging upgrade planned with it, and we quote that together.
Start with the sub: its RMS power and how its voice coils can be wired. Then pick an amp that makes about that much power at the final impedance. Our powered subwoofer comparison covers subs with the amp already built in, and the car subwoofer enclosure buying guide covers boxes.
Everything is bought and installed or picked up at the shop at 22025 S Avalon Blvd Ste A in Carson, and you can ask about our Payment Plan.Stock moves, so call us or text us to confirm the amp is on the shelf before you drive over.

The right sub setup depends on three things: how much space you can give up, how hard you want it to hit, and what radio you are keeping. Small space and a factory radio usually means a powered sub. A trunk or truck cab you can give up means a loaded box and a mono amp. Here is how we point people at the counter, with the parts that come along for the ride.
Read itThe right amp depends on three things: what radio you have, what you want to power, and how much room you can give up. Tell us those and we can usually narrow it to two or three amps in a few minutes. Here is how we walk people through it at the counter.
Read itA 2-channel amp powers one pair of speakers, or bridges to one channel for a small sub. The Pioneer GM-A3702 makes 60 W x 2 at 4 ohms and takes RCA or speaker-level input with auto turn-on, so it can work with a factory radio.
Read itMatch the amp to the sub's RMS rating at the impedance you wire it to. A mono amp makes more power at lower impedance, so check the 4, 2 and 1-ohm columns in our table.
Yes, with speaker-level inputs.
For the largest amps, plan for it. The Kicker Warhorse 49WXA3600.1 listing notes it needs a battery and charging upgrade planned with it, and we quote that together.
Often, yes. Call or text first so we can set aside time in the bay and confirm the amp and wiring kit are on the shelf.
