Question about Alpine MRD-M1005 Car Audio Amplifier
When my Alpine amp is hooked up to my subs, right away when it is turned on, it sends this this really loud bass vibrato type of sound to my subs. When my deck is playing music or not the only thing I hear is the loud vibrato bass noise. Someone told me that it might be something wrong with my ground terminal. If anyone knows what the problem is and how I can fix it, please help.
Here is my problem: For the past 2 months my subs have been cutting out at relatively low volumes. If I turn them up loud enough (about 1/2 max volume), they pound like crazy! It's just at lower volumes or songs with little bass that the subs seem to cut out or simply produce no sound at all. The blue screen is still on like everything's still working but subs aren't pounding. This is a new problem as I've had the system for nearly 1 year and a half with no issues.
My setup: The sub amp is an Alpine MRD-M1005 1000w monoblock. It is powering two Alpine 10" type R subs (2ohm) in a porded box

Try a small piece of wire install it to the rca plugs in back of the head unit strip the end that's plugged in

He may be right! You might try finding a new source of contact for your ground cause it may not be sufficent enough to ground to, also make sure that no wires from the back of your radio have any wires sticking out touching other interfering things that could possibly be causing the noise

Make sure that your amp turn on wire is connected from behind the radio to your amplifier. Usually the turn on wire is a blue wire but it can be any. This blue wire connects from the blue/white wire behind the radio to your small connection turn on connector on the amps power connections. You have 3 ( 12V , Ground, Switch or the smallest connector)
Also check the amplifiers fuses, and the main powerline fuse as well. If this doesnt work then write back to me.
