Rampage amplifier I just finish hooking up my amp and it works and sounds pretty good. When I turn the key I hear a small popping noise from the speakers what is wrong? Also is it normal for the amp light to be on after I remove my key?

Since you have said the speakers make this sound when "turned on", I'm going to assume there's some form of power amplifier attached (internal, external or otherwise). Based on the minimal information provided here, this simply sounds like the normal reaction of a speaker when the amplifier is turned on. In short, an audio speaker is a type of "transducer" and when power is applied (thru some form of amplifier), the cone reacts to the power surge and causes a thump, pop or other noise. Turn on your TV for example and you'll usually hear a small pop from the speakers...and a larger/more powerful amplifier is likely to make a louder noise. Without further information, in most cases this is quite normal.

Assuming there is an external power amplifier, my advice would be to turn the volume on the amp (regardless of whether there's a receiver connected) to 0 before turning the power on. If it still makes such a noise, it's possible the volume control of the amp may require cleaning.

Good Luck!

k then amplifer is the culprit.

Technically, yes, but there are some challenges. First, the input voltage to the amp is 12VDC, not 120VAC. You would need to find a power supply large enough to supply 12VDC at 30-40 amps (plus has proper currently limiting or fuses to protect against overloading). Second, most home speakers are 8 ohm impedance. While the amp can power an 8 ohm speaker, the output power is cut in half (compared to a 4 ohm speaker).

Well it sounds like your amplifier IC's are working correctly since you are hearing that pop. I have the same amplifier and every 10db increment it pops. Have you tried every input? Possibly try starting at a low volume, plug an RCA plug into CD or any other input, and touch the center prong of the other end of the cable. You should get a 60hz hum if your in the USA, otherwise it will be 50-55hz. Regardless it should make noise.

could be bad rca cables or no output from the radio rca outputs. the sub control may be turned off on the radio (ive seen that alot at my work). if all that is fine, the amplifier may be bad. the rca cables may be plugged into the "out" section of the amp. gotta look at all the small obvious things first. good luck.

you blew a mosfet in the amp along the outer edge

If the sub isn't working, you won't get a pop. All you need is a small speaker. Don't need a sub, you just want to test the sound. I recently blew 2 subs, no smoke, no smell, no sign of being blown. Absolutely nothing from the subs.... In the past my sub locked up. You can take your sub out of the box and hook the + and - to the battery to see if you can get the sub to pop there. I believe a small box will push a sub into a deep excursion to the center of the cone. I have 2 lanzar VW12D's that just quit. I hooked a 6 x 9 up to my amp and low and behold I had sound! Try that and see what you get...

thoght i coukd...

you have just popped your speaker or the speaker has disconnected from the voicecoil or just burned out you might have over loaded it!

Check all the wiring. It could be a loose connection since it's intermitent. Really pay attention to the power cable, both the end for the amp and the one that's going to the battery cable.
