Question about Earthquake Sound XTREME 900W.5 Car Audio Amplifier

1 Answer

Fan on Amp turns off with everything off.

I have a Kenwood DDX7019, with an Earthquake Sound XTREME 900W.5 channel amp. I was leaving work and it was like 100 degrees outside, and I add a humming noise I tracked it down to the amp, and found it to be the exhaust fan. I asked a couple of my friends and they say that the amp should not be doing this. They suggested that the remote wire was hooked up wrong. So I tested the cables, and the remote wire is fine. The hot and ground is fine. Any other ideas why the fan on the amp turns on when the car.

Re: Fan on Amp turns off with everything off.

Yes , it is normal for the fan on the amp to turn on when the internal tempature reaches 110 degrees the amplifier is not an intellegent device, all it knows is the temp threshold has been reached and its themostat will close the relay and try to exhaust the heat from the amplifier....I have this same amp, and I live in florida...thank goodness it is a very minimal draw,,,btw if it was a 100 outside it was well above 100 inside your car and even hotter inside the amp ,,the heatsink will conduct heat inside the unit when the unit is the unit is behaving normally...Congratulations for buying a high quality piece of electronics

The subs aren't pushing out bass.

Hello crobins2,

The Kenwood KAC-6202 2-channel is only rated for 60 watts RMS per channel into a 4 ohm load. That just isn't much power for a pair of 12" subs. Even the bridged output is only 200 watts into 4 ohms, still at the low end for a sub, much less to share between a pair of subs.

Assuming that your subs are 4 ohm, you could probably get more sound by driving just one of them on the bridged terminals. But to get the best power with what you have, connect one sub to each channel, set the filter switch to the far right (LPF), set the operation switch to stereo (both channels driven), set the filter frequency (Hz) to 100 or lower, and adjust the input sensitivity as far clockwise as possible without causing distortion.

But, to do the subs justice, you really need at least 300-400 watts to share between them.

Hope this helps.

Wiring problem

If you have an aftermarket stereo, the hook up is fairly simple. On your amp there should be a minimum of 5 terminals and an audio input. one is for remote which is connected to the blue wire on your stereo. Second is your ground which is your negative connection. it should be connected to the body of the car close to the frame. Third is your hotwire which is the positive lead, it should go straight to your battery. The fourth and fifth are speaker wires, you may have 2 or more of these that have + and - signs above or below them. When wiring the speakers make sure to match the positive and negative connections on the speakers. If your rewiring all of the door speakers to your new amp then the colors that you see once you have them out are the colors you route to the appropriate locations on your amp. If this is for a sub then you just the connect th positive terminal on the sub which is red to the + on the amp and the black terminal on the sub the the - location on the amp.

Lastley there should be an audio input that runs from your stereo to your amplifier. This wire should be ran as far away from the positive wire as possible to avoid engine noise coming through your speakers.

Red light is on when i connect input cable earthquake 1000w amp

Cables are either shorted, or deck is putting out too much power for input on amp... many new head-units will put out up to 7v on the output jacks (RCA) the amp may only want to see up to 1v will need to consult head-unit manual for adjustment of outputs.

Sound from speakers muffle mid song

Assuming you've already checked all your wiring, it sounds like a problem in the amp circuitry. Would you say it happens when the amp heats up? I'm guessing an input opamp circuit is messing up when the amp gets hot. If you are electronically inclined you could open it up and look for a poor solder joint. Other than that you will likely have to get it professionally serviced.

1. Check your grounds. (including grounds for your stereo)

2. Check to make sure the power cable you connected to your car battery is properly connected, and not coming into contact with anything metal.

3. Make sure you are using proper fuses.

4. Check your connection from your stereo to your amp, and your amp to your subs.

My Kenwood 800watt amplifier

Sounds like you have overloaded your amp. When you bridge you MUST make sure that you still have the proper speaker load. One 4 ohm speaker on one channel is fine, but when you bridge that same 4 ohm speaker, it gives you a 2 ohm load on each of the two channels that are now bridged. If you made the mistake of wiring two 4 ohm speakers in parallel (plus to plus and minus to minus) then when you bridge you will be driving a one ohm load on each channel. This is very close to a dead short. Stop using your amp at once until you get your speaker load correct. This will damage your amp and it will cause you to have to go to a repair shop to fix it. DO NOT RUN YOUR AMP ANYMORE UNTIL YOU FIX THIS. Good luck.
