I have had the following set up in my car for quite a few years:
AGPtEK A02 8GB MP3 Player output into Fiio E5 headphone amp into cassette adapter for car radio.
It has worked ok, but I've always had to have the volume of both the MP3 player and amp at maximum and then even the car radio about 3/4 max to get a decent volume.
Lately, I've been considering switching out the Fiio amp. There is the A3 model which is presumably double in output power, but coming at a higher cost, but I also recently came across this kit amp:
According to specs, I could run this from 12 VDC in the car and the audio output is specified at 500mW maximum power output @ 8 ohms. I have two questions:
1) Would this be a suitable swap out replacement of the Fiio amp? and2) If so, what modifications, if any, would need to be done to the amp?
Thanks!
