Ok, here is my problem. I have been upgrading my sound system slowly over the past couple of years and I'm almost done. I have good speakers, head unit, 2 layers of dynamat exterme in the doors, and quality connections, but my music sounds very bright and harsh. I think the harsh sound is caused by my Sony amplifier. It's not a cheap model; I paid close to $300 for it. I want to upgrade my amp to improve my sound. There is a new infinity model that circuitcity carries and on paper it looks pretty good. I'm also considering the JL Audio 300/4, but some people have complainted about it being too flat and not musical. I have also looked at Phoenix Gold and Soundstream, but they seem like they are designed to power subs. I have an Alpine head unit, MB Quarts in the front, and Pioneer 6x9 in the rear deck. Any suggestions for a musical and warm amplifier?
