Hi,

I am trying to remove completely the headunit and instead use my smartphone for music in my car.

My idea is this:

Use a laptop charger which has 70W max to power up a small 2-channel amplifier which takes 12v to 24v, (output power: 68W * 2 and Power details are: 68W, 4O / 50W, 8O)

For speakers, I will be two rear speakers, and to keep up the smartphone battery full, I shall use the 5v from the laptop charger.

These are what I thought of buying:

Would this idea work?
