My set up Alpine deck - only has pre-amps thus everything is amp’ed 2 alpine type Rs 10s 2 random door speakers (amp’ed) stock 6x8s (amp’ed) Problem - when I turn up on a CD there is no problem at all. clear clean bass and sound. sounds great at volume 20 when i turn the radio up past 10 its fuzzes and distorts and has no bass or sound. So far i have checked all my wires. I re - conected my antenna away from all other audo / power wires. Later today I’m going to ground my amp to my battery in my trunk. amp is also in trunk. Any other suggestions? ---

I think you’re troubleshooting in the wrong direction… if you know it runs clean with a CD… then it’s got to be either the head unit or the antenna. you also have to factor in how bad radio quality really is and also that radio stations use a ton of EQ to make bad systems sound louder. I have two different EQs for radio vs CD and I still don’t listen to radio very much. ---

yeah… but if it’s “source dependent” then it’s either the source, or the preamp (in this case your headunit). ---
