I am researching several different methods of adding a little more
punch to the audio system of my 2009 TSX (without Navigation). One of
the potential solutions is to upgrade the factory subwoofer with a
higher quality unit. However, this bring with it the question of
whether the factory amplifier would provide enough power to supply the
aftermarket subwoofer?



What are the specifications on the factory amplifier and subwoofer?

- Wattage to subwoofer channel?

- Subwoofer wattage rating?

- Subwoofer frequency response?

- Subwoofer resistance (ohms)?



Any information you can provide to me would be extremely helpful. Thank you in advance!

For those that are also seeking this information I received an answer on another Forum (Honda-Tech).



The wattage on the subwoofer is only 20W RMS and 40W MAX. The
resistance on the Factory subwoofer is 4 ohms (which I had an
opportunity to verify this morning)

Low wattage is exactly what I expected.

Look to buy an aftermarket amp which accepts speaker (powered) inputs. This will prevent you from running RCA wires from the head unit (which most likely will not even have RCA outputs). Otherwise, there are units which convert speaker inputs to RCA output which will plug into any amp.

You can get the "signal" from the existing wires, but either way, you will still have to run a power cable to the battery.
