Subwoofer makes a loud bass machine gun noise when powered up

Hi, I have an alpine ida x-300 stereo in my car with 2 500w subwoofers and a 1200w amplifier in my boot. The system used to work absolutly fine until the last few months. Now when i power up my system the subs make a VERY loud machine gun sort of bass tone for around 2-3 seconds as they power up but then play absolutly fine for hours and hours until i turn off my stereo and turn it back on at where the subs make the noise again. Even when the volume of the stereo is on 0 it is the same loudness as if the volume was on 30. (It is so loud it makes you jump.) The noise is now extremely annoying and even embarrasing when for example in a car park turning on my stereo ready to leave. I have tested all of the connections and they seem fine. I was wondering if installing a capacitor would help :S Could someone please help me! I would really appreciate your suggestions, Thanks.

    Sounds fun :D

    Capacitors turn an alternating current into a smooth, steady current, in fact, this is why LEDs fade out when the device is turned off.

    I'm not an audio guy, but your setup sounds power-consuming. Try getting your battery checked, as the 2-3 seconds of loud could be your battery struggling to keep up with the load :P

Are your power wires on the same side as your RCAs? Is so, i would buy a new rca cable and run it on the other side of power wire. For example i have my power wire on passenger side and the rcas and speaker wire in driver side.

Well, I have the same problem and I would think it has something to do with the RCA-connections. If I power up my head unit while I have my main fuse for the amp's removed and then replace the fuse as the head unit is already playing music (thus putting out a current through the RCA-connections) it works just fine. But if I just power up my stereo with the fuse in, my subs go all crazy. I guess it has something to do with disruptions in the rca cable. Maybe they are drawn too close to some power cables or speaker cables? Good luck!

Press the Rotary encoder (CDE-9845/CDE-9843

to choose the desired mode.
Each press changes the modes as follows:

You could get a stereo installation kit for your year, make & model, that comes with a pigtail plug that would plug right into the existing harness plug and prevent you from having to hack up your original wiring harness.

If not....

Car Radio memory Constant 12v+ Wire: Orange
Car Radio Accessory Switched 12v+ Wire: The radio harness does not provide a switched power source. Run a wire to the fusebox for switched power.
Car Radio Ground Wire: Black/White
Car Radio Illumination Wire: Gray
Car Stereo Dimmer Wire: Brown
Car Stereo Antenna Trigger Wire: Pink
Car Stereo Amp Trigger Wire: N/A
Left Front Speaker Positive Wire (+): Tan
Left Front Speaker Negative Wire (-): Gray
Right Front Speaker Positive Wire (+): Light Green
Right Front Speaker Negative Wire (-): Dark Green
Left Rear Speaker Positive Wire (+): Brown
Left Rear Speaker Negative Wire (-): Yellow
Right Rear Speaker Positive Wire (+): Dark Blue
Right Rear Speaker Negative Wire (-): Light Blue

Good luck

Alpine ida-x001 volume is low even if stereo is turned all the way up only when ipod is plugged in on ipod setting.Radio (AM/FM) is normal volume (louder)..How can I fix this?

Most newer car receivers have a feature named something like "level balancing" in which you can adjust the relative loudness of each input (Tuner, CD, AUX, IPOD). Check you owner's manual for a similar function.

Also, are you or can you turn the level of the ipod itself up a bit?

Subwoofer doesn't play through ipod, only radio and cd's

Hook up the remote wire from the head unit (grey w/ orange stripe) to the power antenna wire (blue) on the wiring harness adapter.

Alpine x200 Subwoofer Preout pushing out a weak signal

Hi, just turn up the gain, though the max voltage may be higher, it does not mean the audible output is higher, alpine decks subwoofer control is an attenuator, so at max it will be the same level as front n rear, on min it is -15db... you will probably find the kenwood is +/- 7db so it has a gain boost...
just crank up the amp gains, problem sorted...

Bass sounds only

That is tricky one. Did you try adjusting the EQ on both the stereo and the amp? Is the Mute turned on because it will act like that? Is both rca jacks plugged in on stereo and amp?
