Procedure for installation

  • Be careful you use a solid power wire with fuse (if desirable) to source power from the battery terminal in your car’s trunk area to your subwoofers.
  • Unless your car come with a line -out converter which taps into your factory fitted speaker, you will need run RCA cables directly from the back of your radio deck to deliver signals to the subwoofer which notes to recognize and play.
  • A remote wire which instruct your amplifier when to turn on or off is needed to connect the LOC or the radio deck. If you fail to put this, your amplifier will just be on permanently and this can drain your battery.
  • There is also the need for a solid ground cable for earthing. Connect this to a bolt somewhere in your car’s trunk. Be sure it is connected to an unpainted bare metal surface for best connection. Once all these are done, be prepared to hook up your amplifier to the subwoofers.
  • Like we just mentioned above, ensure that your amplifier and subwoofers are compatible. This mean that both their rms and wattage matches to avoid a blow up of either or both gadgets. It is advisable that you neither over-power nor under-power your subwoofers for any reason, for this we recommend 100 watts for accurate performance.
  • Start with the disconnection of your car battery’s negative terminal to prevent electric shock or fuse being blown off.
  • It is time now to mount your amplifier in a chosen location preferably where it will enjoy a lot of airflow to prevent it from being damaged by heat. It is paramount to note that the location should not be too far from the subwoofers for good result.
  • Connect your RCA cables in the appropriate slot and pattern matching white to white and red cable to red connection correctly.
  • Connect your speaker wire to the subwoofers now also matching correctly. If you have an enclosure in your subwoofer, match the speaker’s negative wire with the black terminal of the subwoofer and the speaker’s red wire with the positive terminal of the subwoofer.
  • Then join the other negative end of the speaker wire with the negative slot on the amplifier as well as the positive end to the positive slot on the amplifier alternately.
  • Connect the ground cable to the slot labeled ‘ground’ on the amplifier and the remote wire to the slot labeled ‘remote’ on the amplifier then connect the power two power wires together. Please be sure you secure all wire connections very well to prevent bridging.
  • You can now connect your car battery’s negative terminal.
  • If your power light on the amplifier is ‘ON’ now, it is time to start enjoying good cool solid music in your car!
  • Go back to the whole process and re-check your connections, dot all ‘i’s and cross all ‘t’s. Solder all wires that is needed and tape all wire connections that should be taped. Replace every opened space such as the dash board, e.t.c to restore your car back to its original neat position.

Surely, if you adhere to the above guidelines and systematically follow up, you will not blow up your speakers and subwoofer after installation and you sure will have an improved sound quality.
