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.
