hooked up the amp today and im hearing noise coming from it. Is that a fan inside or should I be concerned?

It's probably the fan because it's pretty loud when it's trying to cool down. I suggest you mount it on a flat un carpeted surface to let air circulate better. Mine always ran hot so I had to build a amp rack for it with 2 fans on the bottom. If it starts overheating like mine kept doing, you might need a bigger, better amp.

It's does when it turns on but I think it might be because it's too cold but then it starts to go away in a few seconds but it has been working very good, better than the sony amp I try.

As long as your fan is clean, there really shouldn't be much noise under different load mods. I haven't heard that the fan is an issue.

Check that all wires are fully connected. Other wise it would probably be something internal in which case yeah I would return it. Other thing would be speakers but if you only noticed it with the new amp then there's your issue.

It's a bad amp. You will have to get a new amp I had the same thing and had to get a new amp.

Hi. All I know is that it cant run more than 4 amps reliably and the devices fan is louder than it should be.

sounds like it has a problem, there should be no noise coming from unit, contact manufacturer or place of purchase.

the amp is at 4 ohm load, 2ndly are you asking about the implications of series or parallel hookup, hook it up to stay at the 4 ohms,= series. read a bit on the net about series & parallel. try them one at a time, noting amp temp,! aka does the fan come on? mine never did, so if yours does your pulling serious juice & sensitivity how much pre-amp line voltage required. are these subs or full range & are they in stock cabinets?

I am hearing the motor too along with the white noise... I wonder if it's normal or if my unit has a defect.

It sounds like you are getting FM noise coming in. This can be from the AC wiring in your house or from the speaker wire and since you replaced your speaker wire I would suggest trying a noise supressing surge protector of some sort. Monster Cable makes some great ones for that they are rated in what they call there clean power stage Monster MP PRO 800 with Clean Power Stage 1, Surge Protection, and 8 Color-Coded Outlets High Performance Pro PowerCenter

If your not changing the amp stick with the same ohm. Otherwise it might sound like crap or worse and blow something.

The buzz is not from the amp check all of your cable connections and ground fault. We use ours all of the time and the only time we have heard a buzz was from a dimmer switch for the lights in the club.

No idea, check your install and make sure it's well supported, mine has no noise like that.

We deployed this unit out to a client so its not something that I have daily interaction with. However, I don't recall it being something that stood out to me or if I even noticed any fan noise at all. I know that isn't a great deal of useful information but wanted to get a response back to you.

I think something is not right if it is 'extremely' loud. Mine was not silent but it was like a low hum.

Mine makes a little bit of of noise, but not too much. I believe it has an internal cooling fan, but I'm not 100% sure on that. Sorry, this probably not that much help.

Mine did the same thing. Not sure if it's a good/bad thing but the amp is good. Hope this helps

I hear no such noise in mine, however, I always leave mine in standby mode. I suspect you have a noisy cooling fan.
