Strange Starting hum as amp tries to turn on?

Ok I really love this amp first off. But Ive had tons of troubles with it also, it all started when I was cleaning my car and accidently completed the circuit where the speakers + and - connecr after that it made no sound at all, so concerned took it to a repair guy who took forever to repair it. So I just got it back a couple days ago and hooked it up an to my 3 eclipse allum subs. But yet again I can notice the amp tries to turn on but is also greeted by a strange humming and crackling noise as the amp turns off to deaf ears:(

Re: Strange Starting hum as amp tries to turn on?

First of all you need to look at the specs on the amp and see what ohm load rating it runs at. for example  (4 ohms @ 200watts)   and check your configuration because if you go below that rating  for instance if the amp only can do 4 ohms and you parallel them speakers down to 2 ohms  the amp will go nuts and blow up.    After you find out informations about the amplifier ohm your speakers out with an ohmmeter and see what resistance you have on your single / dual coils   and wire them up to proper configurations so that your amp and subs are matched.     ALso check your RCA'S  For signal problems.

I just hooked up my RF 325.1 Amp to my Sony CDX-M30 deck and a small 10" Alpine Sub in a small box. I ran the wiring according to the install instructions for the Amp, but I am getting a very loud...

the reason for the 3' min. on your ground cable is that interference is picked up with longer gound cables. Especially if it passes close to any electrical components, e.g. spark plugs, capacitors, anything with electrical current. These signals are amplified within the amp. (because this is what amps do) and distributed to your speakers. you could try a noise filter / noise suppressor but I've never had luck with those. You could also try finding a metal part of the frame (if there are any) and attach your ground to a bolt along that frame and if your more advanced you could create a hole and use a screw to tighten the ground to the frame. Small note to that, boats create a lot of vibration so use a ground screw with a sort of tooth like seration at the head that grips as it tightens (so it won't come lose). If you have an extra battery you may want to attach the amp directly to an independant power source to see if your getting the same hum. A direct short in your electrical system will create the same sounds. A bad ground your electrical system will do this also. You may also want to check you high and low band pass frequencies if applicable. Set them to high and you'll get a hum. I would start there adjusting them down or setting them to the center and adjust accordingly if this stops the hum. I'm running 4200 watts all together and if I adjust to high I get interference just from the force of the amp itself. Good luck. Hate electrical problems on vehicles, too many wires.

My brother just bought an A2300HCX and almost the same thing happen. 1 of the gauges (left side) was no movement. We tryed hooking the amp to the right side, and it works. The Left side turns out was shot, had to get it fixed. So sorry to tell you but sounds like one of the channels has internal damage. I know this isn't the good new you were wanting to hear, but hope it was helpful

Noise in my car amp.

sounds like you have a bad ground going to your rca's. try running a wire from ground to the shield of your rcas and see if the noise goes away.

Can anybody help me besides best buy for $80 an hour??

First of all if everything is wired right then your amp is defective. If you have The B+ wire from amp to the fuse block then to the positive battery post, Then if you have a good solid ground going to the amp, and you have 12 volts running to the remote on the amp when you turn the head unit on or a switch for the remote turn on, then you should have no problems.For one, I would test the voltage at the amp with car off and key off. Take the probes of the meter and touch them to the amps ground and positive terminals and check those readings. If ok turn key on and do the same thing, leave head unit off. If ok turn on head unit and test voltage at the positive and remote terminals using the amps ground. If you have any problems before the last test I said to do then thats where you should start to find the problem. Otherwise if the power drops it maybe a bad ground or else you'd start burning up fuses. Let me know what you found out or if you figured it out. I would like to know what it was. I own a car audio/video install business as well as amp repair. Send me a message so I can find out what it was please.

Directed 1100 d turns on but no sound

hi there
few steps to try
1) try grounding amp to a new location
(make sure the amp is grounded by itself)
2) check the power wire from the battery to the amp
3) if the 2 steps don't solve the problem try turning your amp settings down and disconnect the power wire from the amp after a few seconds reconnect the power wire and amp should reset itself.........
if this doesn't work let me know there are other tricks that can be done but these are the most common firsts to be tested (also make sure the ground wire is larger than the power wire)
hope this helps

No noise A2200HCT

To determine what failed, you would have to open the amp while it's powered up and measure the voltage at several points. If you're not comfortable with doing this, you should pay to have it repaired. If you want to try to repair it yourself, read through the following page.

Basic Amplifier Repair

You'll need a digital multimeter.

Let me know if you want to try to repair it yourself.

If the amp produces no boom with no signal input cables connected, I'd suggest using an LOC.

Let me know if you have any other questions.

Sony xplod xm-554zr amp

if you are trying to run some highs with built in high-pass crossovers off of a amp that is setup for subs(amp is on low-pass) then your highs will not work. You are better off running another amp or running them off of your deck...
