Got a bit of a problem with my speaker in the clio at the minute. I have a set of comps in the front and a sub in the boot which run off an amp, which supplies 60w rms to comps and 120w to the sub. Now i also have a set of 4" coaxes in the back of the car, which run off the headunit at 50w rms. The problem i have is whenever i have all of them plugged in and turn the volume above 30(i need to as my phone is quiet ) i get lots of static noise and distortion from the rear speakers. now when i run just the rear speakers by themselves i dont have this problem. Is it possible my clio just doesnt have enough power?
