Feikeer 10" Slim Underseat Subwoofer with Amp 1200W

Feikeer’s NEW 10" 1200W slim underseat subwoofer with a built-in amplifier delivers tight, deep bass from a compact enclosure designed to fit under seats and in tight truck or SUV spaces.

This underseat subwoofer and amp package combines a 10-inch driver, 300W RMS (1200W peak) power handling, and adjustable tuning controls to add low-frequency extension without dominating cabin space. Its slim chassis is intended for installations under car seats or in small cargo areas, giving vehicles like trucks, Jeeps, SUVs and MPVs fuller low end while preserving interior room. The unit includes individual controls for low-pass, gain and bass boost so you can tailor the output to your music and vehicle acoustics.

How does this compact subwoofer improve my everyday listening?

Installed under a seat or tucked in a corner, the Feikeer subwoofer fills in frequencies standard speakers often miss, delivering punch and rumble that make tracks feel complete. It emphasizes low-frequency presence while preserving midrange clarity, so vocals and instruments remain intelligible.

• 10" driver for extended low-frequency response down to 20Hz.
• 300W RMS / 1200W peak power for impactful transient response.
• Frequency range 20Hz–500Hz to cover deep bass and low mids.
• Compact slim profile fits under seats of trucks, SUVs, and MPVs.

What controls and tuning options does the amp offer?

The built-in amplifier provides dedicated adjustments so you can match the subwoofer to your vehicle and personal taste. Use the low-pass filter to set the crossover, the gain to balance volume with factory speakers, and the bass boost to add presence at 45Hz when you want extra punch.

• Low-Pass Filter: adjustable 50Hz–150Hz for precise crossover settings.
• Bass Boost: 0–12dB boost centered at 45Hz for additional low-end weight.
• Input sensitivity options, including high-level and low-level connections.
• THD under 0.4% and SNR >90dB for clean low-frequency output.

How should I set it up for the best sound and durability?

Place the subwoofer under a seat or near a trunk corner to reduce cabin rattles and preserve interior space. Start tuning with the low-pass filter around 60–80Hz and increase bass boost slowly until the lows feel defined without muddying vocals; avoid extended extreme volume to protect the speaker and hearing.

• Recommended low-pass starting range: 60–80Hz for balanced bass.
• Gradual bass boost adjustment to prevent boom or distortion.
• Position near seat base or trunk corner to minimize vibration transfer.
• Fuse rated 25A; avoid protracted maximum output for longevity.

What technical specs will affect compatibility with my vehicle?

Check impedance, wiring options and space constraints before purchasing. The Feikeer unit is 4 ohms nominal, offers both high-level (speaker-level) and low-level (RCA) inputs, and includes mounting options suitable for many vehicle under-seat locations.

• Impedance: 4 ohms — matches standard car audio systems.
• Inputs: high-level 0.9V and low-level 300mV compatibility.
• Power handling: 300W RMS with 1200W peak capability.
• Includes accessory replacement guarantee for 1 year.

Who is this product for?

It suits owners who rely on factory or compact aftermarket speakers but miss low-end extension, DIY installers seeking a tidy under-seat fit, and anyone who wants adjustable controls to match different music styles and vehicle acoustics.
