If this occurs with the head unit plugged directly into the amp (no signal processors inline, you probably have open shields on the head unit.

To check the shield ground, disconnect all RCA cables from the head unit and measure the resistance between the RCA shield on the head unit and the case of the head unit. It should read ~0 ohms.

Alpine CDE 141 will not output to sub

Your description is not very clear but my guess is that the output from the RCA connector on the head unit (receiver) is low level and intended to be connected to an amplifier input. Apparently the 3.5 mm "jack" (plug) connects something to the RCA input of the amp and that works.

Popping noise on my 12" type r subs

The subs are making that sound when the bottom out + when they reach full excursion be careful if it keeps happening eventually your subs will fail because you will end up damaging the subs voice coil.

JL Amp isn't powering subs and speakers

silly as it sounds, you may want to check your EQ settings on your headunit. Things like sub volume, SLA, loudness and balance. When they replaced your battery, those old settings were lost.

How do i get my Alpine CDA 9885 head unit out to fit a sub???

Remove the face, and trimring plastic.
There are slots on either side that you put the Alpine unlocking keys into (came with your headunit new) then slide the chassis out.
If you don't have keys - you can use a small allen wrench - or buy them at best buy etc.
A local alpine dealer will probably let you borrow his keys as a good business practice.

Subs have almost no sound coming from them

Hello meow_mix_666,

If you have tried different amps and different subs with the same result, I'd definitely suspect that you are not getting enough of an output signal from the head unit. Checking the RCA's and perhaps using a different set of preamp outs would be a good idea.

One other possibility that you may not have considered is to check the phasing. I've run into speakers that had the markings reversed and running the subs out-of-phase on a 4-channel bridged would make a huge difference in the bass.

Hope this helps.

Connect alpine 7874 to alpine powered sub

You need to run the RCA cables from the head unit to the sub for the audio signal, and possibly a turn on wire (the blue one on the back of the head unit), unless the sub has an automatic power feature.

The sub also needs power and ground wires attached, but those do not connect to the head unit. Power should be run directly from the battery with an inline fuse, and ground should go to the nearest good ground point (Trunk latch, seat bolt, etc).

Cant figure out my car audio problems!!!!!

There are a couple of tests you can perform. I'd first recommend checking the shield ground. You'll need an ohm meter. The details can be found on the following page.

RCA shield ground test

You can also test the output with the multimeter. Set the multimeter to AC volts. If it's not an auto-ranging meter, set it to a voltage range of ~2v AC. Disconnect the RCA cables from the head unit. Touch one meter probe to the outer ring of the head unit's RCA jack. Touch the other probe to the metal contact in the center of the RCA jack. With the head unit near full volume and a clean signal source, you should read at least one volt on musical peaks. If you have a bass disc or a test tone disc (~60hz sine wave), use those.

Annoying thump from two 15" kicker comps powered by a lanzar vibe 266 amp

It sounds like it may be oscillating. This can be caused by a broken ground in the signal line. You need to check the RCA shield on the head unit.You'll need an ohm meter. The following page has more details. If the head unit isn't damaged, the shield ground could be open in the amplifier.
