Why dont I get sound from my speakers but the radio works


If you have an equaliser, check that you havent accidentally pressed the button which switches between the main input and aux or bluetooth. Right, if you have aftermarket sound system, check that your RCA's/(look like av cables) arent unplugged broken off or damaged. Another thing is to see if the amps come on (usually shown on amp by a green light) red if not on. Check the power wire from the battery to amp, check if fuse is not blown. Ground the amps properly for the amps to come on and check that the power cable is connected properly as well. Another fault could be blown speakers.

Make sure your safety mode is off. Go to mode 9 and ENT and make sure it is off. If it still dont work you proabably have bad RCA wre or speaker wire. Hope this helps!

Check the remote lead and see if it is getting power at the amp when it won't come on that way you know if the issue is with the head unit or the amplifier.

It sounds like you may have a power-supply problem. You need to measure the DC voltage across the B+ and ground terminals of the amp. If it doesn't remain near 12v when the amp is on, you need to determine why the voltage is dropping. It could be due to a defective fuse or a corroded connection at the battery.
