Finally completed my sound system in my car.
Got a new Kenwood 4 channel 600 watt amp.
This fixed the white noise from the cheapo boss amp.
Everything sounds crisp and clear now which is nice.
This amp is TINY.
Stuck it right in the tool box slot.
I also got a new Kenwood head unit (DDX375).
It's bluetooth and touch screen and works pretty well so far.
The only hang up I had was that it has a spotify app built into it so when it connects it puts spotify on your phone into "dock" mode. Which basically means you can't change the song or control spotify from your phone.
The work around this is to turn off auto connect for spotify and then connect the phone as a "bluetooth device" and then you will be able to control spotify from your phone. You are also able to change songs play / pause straight from the head unit too which is nice.
