Try switching it with the good speaker if it still doesn't work then the amplifier is dead on one of the channel

Why did speakers get really loud, then stop working?

Have you checked the fuse on the amp and/or make sure the amp did not burn out?

I was using bridge on a Rockford P300 and blew my cheap speakers but now my bridge doesnt work. Bought new speakers and want to run in bridge mode is there a fuse inside maybe or did I blow it up?

Disconnect all speaker connections and rca cables. Leave power, ground and remote wires intact. Try turning on again. If you still have a protection light your amp is faulty. Hopefully you have warranty. Your amp is clipping.
No internal fuses. Your mosfets are toast. A thumbs up would be greatly appreciated if this answer is helpful to you. using-bridge-rockford-p300-blew-peeu4x5nsxvd53n2rwetiqa4-3-0.jpg

Rockford ravdvd2 has power; no functions will work

which power wire did you hook up? You have 2 hot leads that need to be hooked up. one is from accessory side of ignition that turns the unit off and on with the key, and the other is a constant hot to retain memory presets and other tuning setup information. You might have only one of the two hooked up.

I installed a sony 600watt amp and it works but old rockford fosgate 200 hit harder how do i make my amp louder and evenly spread throughout my car

Hello jmanbutt99,

The old Rockford-Fosgate was probably producing the rated power. The Sony is most likely overrated. But, it's supposed to be stable on each individual channel down to 2 ohms and will deliver 65 watts RMS into that load. So to get the most from it, your best bet would be a pair of 4 ohm speakers paralleled to each channel. A relatively efficient speaker like the Kicker 07DS600's shown here should provide pretty good sound.

These will work with as little as 6 watts RMS and can handle up to 50 watts RMS so the Sony should power them really well. They're 4 ohm so a pair in parallel will present a 2 ohm load.

Hope this helps

Left positive speaker input stopped working

try swapping over the rcas for instance if black is in r and red is in l then swap them so red is r and black is l

if that doesnt work try swapping the subs over to as you may have a faulty sub. if that doesnt work then check the fuses on the amp

still no joy then i would suggest taking your amp to your local car audio dealer and getting them to have a look at it

Hope this helps if so please dont forget to rate

best wishes
