What's the audio input?

What's included in the packing list?

The packing list includes an amplifier, DC 12V/5A power adapter, and manual.

What's the working voltage of this amplifier?

The working voltage of the amplifier is DC 12V.

How do I connect the subwoofer?

The green port is for passive subwoofer. Please use raw speaker wire to connect it.

What does 'btl out' on the top of the case mean?

BTl is a kind of amplifier circuit. It means Balanced Transformer Less.

Are the two rca ports in the back input or output ports? I would like to input sound via the front aux port, and output sound via the rca ports...

The two RCA ports in the back can function as both input and output ports. You can input sound via the front aux port and output sound via the RCA ports.

Can it be plugged into 110 outlet? Or USB?

Its power supply can work with 100~240V, so it can be plugged into a 110 outlet. However, it cannot be powered by USB.

If I connect 2 different audio sources (aux & rca), do they both get processed & played?

The inputs are paralleled, so as long as you don't play both at the same time, they will both be processed and played. However, be cautious of ground loops and potential interference when using multiple sources.

How do I hook this to a battery?

You will need to get a male plug that fits into the power plug on the amp and wire it to the battery instead of using the power supply. Ensure the center of the plug is positive and the outer is negative.

It comes with an AC adapter. How do you supply power from a battery for boat use?

You can use a Male DC 2.1mm x 5.5mm Wire Power Pigtails Adapter to connect the amp to a battery for boat use.

If this has a sub output, what are the frequencies crossed over for this 'sub' output? Does the sub knob control the output frequency range to the sub?

The sub output has a fixed low pass starting somewhere between 80 and 100 Hz. The sub knob only controls the gain, not the frequency range.

Will this work for .wav files?

As long as the device you are playing the .wav files on has audio out, this amp should be able to play them without any issues.
