ok i posted up here and my stock amp supposedly is blown but i reconnected it and it worked but i have this ringing sound now.the main reason for this posting is bc i want to upgrade my speakers and upgrade from the stock amp, but i want a very crisp sounding system.right now my speakers are sftermarket but its very distorted and no where near crisp.im also willing to upgrade my head unic from my kenwood cd player.any input on a stereo setup will be great.im just tired of having stereo problems i just want to redo it all again and do it right this time.
