I currently have a Pyle 4 channel amp, 2-6.5 junk Dual brand speakers mounted up front. It sounds alright but looking for more volume and better EQ control. It sounds like it doesn’t have very much treble. I am using an ipod to play the music and i know about the EQ settings in it. Think a preamp would help me get a little more volume and better sound? I’m planning on upgrading speakers asap as well. Link below for the exact amp i have.
