I got an amplified bass tube for fathers day and wanted to hook it up in my '09 Corrola. Can I just wire it to a rear (back deck) speaker or do I have to wire it to the radio? If so how do I do it. I'm sorry but it came with no instructions and I don't want to pull the radio if I don't have to.

 

You are going to need a 3 primary wires and then the signal input wires.

You will need a 12V power and ground, a 12V switched power to turn the amp on, and an input signal.

You may be able to find a wire in the trunk that is12V switched power, but you are going to have to run a power wire from the battery. The negative goes to chassis ground. if your bass tube can handle speaker level inputs you can run those from the rear speaker.


Sorry, but I think you have a lot more work then expected.

 

so is it like if you were to hook up an amp?

 

exactly the same except you do not have to run wire from the amp to the speaker. IF it has a high level or speaker level then you can use the rear speakers as your signal source but you may have noise.
