OK...so I just recently got an Orange AB200 head and an Orange 4X10 new. I've played 2 basses through it so far (admittedly somewhat "inexpensive" basses...I'm still saving for my Ric). Whenever I turn up (volume and gain past halfway) the amp buzzes loud and violently. What's causing this?

Is your sub single voice coil or dual? If it's dual, is it wired in paralel or series? It's possible for an amp the heat up so fast, the outside is not hot to the touch. Also, the next time it happens, use a paperclip and short the 12+ to the remote wire on the amp and see if it comes on. Let me know, and be sure to leave feedback or I don't get paid

SOURCE: amp going into protect mode

If you set the gain too high on the AMP, at loud volume levels some clipping or distortion of the output signal will occur. Most amps have a Circuit inside that detects this clipping or distortion and applies protection to prevent damage to the speakers and the amp. It would help to know if you are driving the speakers with a Line level output or using the speaker output from your deck. There are many things that can cause an amp to go into protect mode, and knowing a little more about your setup will help to solve the problem.

The problem you have mentioned is a common one with old sets, but it also occurs in new ones also, though not frequent. You can fix this just by changing the electrolytic filter capacitors in the power supply and sub filters on the amp PCB. The new capacitors should be of the same or higher voltage rating and same capacity rating as of the existing ones. And as it is such an old one, it is better to change all the electrolytic capacitors to avoid any further problems.

SOURCE: Amp went into protect, but front speakers sound distorted too

If the amp still goes into protect mode, the easiest thing to do is disconnect the RCA cables from the amp and see if still goes into protect mode (after turning off/on). If it does, the issue lies in the amp or the wiring to/from the amp (most likely case). Check to make sure no speaker wires came loose and touched +12V or ground (car body). From the sound of it, my guess is something internal to the amp died and will need repair.

SOURCE: amp cuts out when turned up

that amp cutting out like that means that its probably shot and it time to start looking for a new one
