Features / Controls / What Comes in the Box
Features:
Remote bass level control (wired) — you can adjust the sub volume from the driver’s seat via the included remote module. Crutchfield+1
Low-pass crossover — variable between 50-150 Hz, so you can match what your main speakers are doing. Xcite Audio+1
Bass boost — gives extra +12 dB boost around ~50 Hz. Good if need more rumble in low frequencies. Crutchfield+1
Phase switch (0° / 180°) — helps align with the phase of your car’s speakers to avoid cancellations. Crutchfield+1
Audio-sense power turn-on when using speaker-level inputs — automatically turns the sub on when it senses a signal, avoiding the need for a remote turn-on wire in that setup. Harman Audio+1
What’s in the Box:
The BassLink Mini unit itself Crutchfield+1
Wiring harness for power, ground, remote, etc. Crutchfield+1
Remote bass level control with cable (~16.5′ / ~5 m) Crutchfield+1
15 A fuse (one spare included) Crutchfield+1
Mounting hardware / brackets / screws to secure under seat or other location Crutchfield+1
Installation / Use Notes
Because this is a powered unit, you don’t need a separate external amplifier. The built-in amp runs the woofer. Crutchfield+1
For good performance, the power wiring should be capable — many installers recommend using a 10-gauge power cable to supply it. Crutchfield+1
Mounting is typically under the passenger seat or somewhere similar where height is limited. With height of ~3″ it fits under many seats. Xcite Audio+1
Make sure ground is good; enough ventilation so the amp doesn’t overheat. Harman Audio+1
What to Expect / Limitations
Because of its small woofer and compact enclosure, the bass will not hit as deep or be as loud as a full-size subwoofer in a large enclosure. This is more for subtle strong bass or “feel the low end” rather than earth-shaking boom.
At high volume / low frequencies (near the lower end of its response, ~30 Hz), distortion may increase unless gain / power is managed properly.
If the car has a lot of road noise or weak door panels, some of the low end might be less noticeable.
If you want, I can pull up some comparison between this BassLink Mini vs alternatives (same size/price) or how it does in Indian market (price & availability) so you can decide whether it’s worth it. Do you want that?

Here’s a detailed description of the Infinity Reference 7005A (REF-7005A) 5-channel car amplifier — its specs, features, and what to consider. If you like, I can also check its availability/prices in India.
Overview
The REF-7005A is part of Infinity’s Reference series. Crutchfield+1
It is a 5-channel amplifier: 4 channels for full-range/front & rear speakers + 1 channel dedicated for subwoofer. Crutchfield+1
Uses a Class AB/D design: front and rear channels are AB, the sub channel is Class D. This helps with efficiency (especially for the sub) while retaining good sound quality for the speakers. Crutchfield+2sonicelectronix.com+2
Power Ratings
| Configuration | Front/Rear Channels (4) | Subwoofer Channel (1) |
|---|---|---|
| At 4 Ω | ~ 50 W × 4 | ~ 320 W × 1 shop.infinityspeakers.com+3Crutchfield+3sonicelectronix.com+3 |
| At 2 Ω | ~ 65-75 W × 4 | ~ 500 W × 1 Crutchfield+2sonicelectronix.com+2 |
| Bridged (front channels) | ~ 140 W × 2 at 4 Ω (when you bridge two of the full-range channels) Crutchfield+1 |
Total RMS power output is approximately 760 watts depending on load and configuration. sonicelectronix.com+1
Inputs / Crossovers / Controls
Input types:
Low-level (RCA) preamp inputs. Crutchfield+1
High-level (speaker-level) inputs are supported, with provided adapter wires. Useful when using factory head units without RCA outs. Crutchfield+1
Crossover / Filters:
Front & rear channels have variable crossover filters: either high-pass, low-pass, or full-range. Frequency range approx 32 – 320 Hz, with a slope of ~12 dB/octave. Crutchfield+1
Subwoofer channel has a low-pass filter in same ~32-320 Hz range. Also has bass boost (0-12 dB) at ~45 Hz. And a phase switch (0° or 180°) to align with other speaker phase. sonicelectronix.com+1
Remote control: includes a wired remote knob (RBC remote) to adjust subwoofer level from front of vehicle. Crutchfield+1
Other Features & Build
Protection circuitry: safeguards against short circuits, over/under voltage, temperature etc. sonicelectronix.com+1
Signal-sensing turn-on (for compatibility with factory radios) and a remote turn-on terminal. Crutchfield+1
Compact footprint for a 5-channel amp: dimensions are approx 14-3/16″ × 7-1/8″ × 2-3/16″ (≈ 360 mm × 181 mm × 56 mm). Crutchfield+1
Fuse rating: uses three 30A fuses (total ~90A) for power protection. sonicelectronix.com+1
Performance Expectations & Use Cases
Good for a full car audio setup: you can power all four doors/front + rear speakers plus a subwoofer with one amp. Reduces need for multiple amps.
Because of its Class D subwoofer channel, you get high power to the sub without very high current draw or heat compared to a full AB sub channel.
The adjustable crossovers, bass boost, phase switch help in tuning the sound to your car (especially useful for getting the sub to blend well).
What to Check / Limitations
Requires strong power wiring (preferably 4 AWG) and a solid ground to perform well. Poor wiring will cause voltage drops, reduced power, or distortion. sonicelectronix.com
Subwoofer channel at 500 W is when under 2 ohms; make sure your sub’s impedance matches and that the amp can handle the load without overheating or going into protection.
Even though front channels are powerful, they are not super-high power (50-75 W depending on impedance). If your speakers are high power/have low sensitivity, you might want more power for those.
