Question about Rockford Fosgate Car Audio & Video
Nearby where the RCA Cables are plugged into the amp, there should be a "Gain" knob. It is usually a small knob with a flat head screwdriver inset on it. Check to see if this knob is turned down, which is the volume control of the amp.
Turn it up, but as a rule of thumb, try not to exceed 2/3 volume. This will keep your amp from working too hard, which causes it to heat up, which can cause undue stress & eventually damage.
You could also be having phasing issues.
If you have multiple sub amps, make sure the RCA's are plugged in the same way. White to White, Red to Red.
Also, check to see how your subwoofers are connected within the box. If the speaker terminals on the box are positive & negative, and then this is switched within the box, the speakers would be out of phase. Check to see that the positive input of the box terminal is going to the positive input of each speaker in the box. If not, this would cause them to cancel sound from one another, which would result in your non bumping problem.

Check the remote wire that its on. check the know on it that its on low cross over whith decibal gain. also make sure your rca plugs comming from the cd player are in the input on the the amp , good ground and that you didnt plug in the wires wrong for each sub. its very possible you may also have a loose ground connection or a blown fluse. either on the amp or under the hood. but most likely on the amp.
