INFINITY BASSLINK-T 250Watts Powered Sub-Woofer System – WIRING DIAGRAM – CIRCUIT DIAGRAM - Car Audio

Infinity BassLink T Powered Subwoofer System Schematic & Wiring diagram - Exploded View

Output Power(14.4V supply) : 250W RMS

Frequency response: 20Hz – 120Hz
Maximum input signal: 4.0V
Maximum sensitivity: 50mV
Idle Current <800mA
Crossover Slope 12dB per octave
Max Current Draw 26A
Bass Boost -6dB to +3dB @ 40Hz
Dimensions: 40 3/8 x 6 7/16 x 14 3/8” (L x W x D) (1026mm x 164mm x 366mm)
Fuse: 30A

WIRING DIAGRAM

BassLink T is equipped with two line-level (RCA) inputs and two speaker-level inputs.  

POWER CONNECTIONS

Connect power to BassLink T, as shown in Figure. Also observe these installation tips
> Use at least #10 AWG wire for the +BATT (+12 Vdc) and GND (ground) connections. If needed, use at least a #20 AWG wire for the REM (remote) connection.
> Route all power wires through a grommet in the vehicle’s firewall. If a factory grommet is unavailable, install one.
> Connect a short GND wire from BassLink T to the nearest bare metal surface. > For a good connection, scrape away paint from the metal surface and use a screw with a lock (star) washer.
> Install a fuse holder with a 25 A fuse within 18" of the battery’s positive (+) terminal

> The REM connection requires +5 to +12 Vdc signal to turn on BassLink T. Most head units with preamp outputs provide this remote voltage signal. For speaker-level applications, a remote connection is preferred but not required, since BassLink T’s Auto Turn-On feature will sense voltage on the speaker wires to automatically turn on BassLink T.

IMPORTANT To enable BassLink T’s Auto Turn-On feature, set the AUTO TURN-ON switch to the AUTO position
