20 Most Recent Alpine 12" Single-Voice-Coil 4-Ohm Subwoofer Questions & Answers

http://www.alpine-usa.com/support/parts

The voice coils are shot. It's easier to get a new pair as this is a very tidious procedure and not done these days for these kinds of readliy available speakers.

did you smell something funny coming from the sub after it stop playing if you did you blew a voice coil

When you say these are dead, is the voice coil open? If so, the easiest way to fry a coil is to send it high frequencies that it can not reproduce or to send it a distorted signal. If you know anyone with a scope, scope the output when you have it running. Normally the low end will be a relatively smooth curve. If the curve is made up of a really jagged line, you may be passing harmonics through the amp that can heat up the coil causing it to fry. Check the output of the amp with a volt meter. When cranked up you should get no DC voltage at all. If there is DC, that too will do nothing but heat up the coil.

Keep us posted.

Does it play the tuner but not the CD?

If it so, the problem is directly related to the CD deck. If not, the problem could be a sensor or any number of other components that may have overheated.

Try to reset the unit. Most of the time this error is an electrical problem not fixable by the end user. But it is worth trying to reset the microprocessor and see if that helps.

Here is a diagram of where the reset button is at. Press it in with the tip of an ink pen or paperclick, whatever you have that will fit into the little hole. Just hold it in a couple of seconds. Be advised that when yo reset the unit, you will loose all things in memory like the correct time, preset radio stations ect.

If this does not help you will need to have it checked out by a good repair center. These Alpine radios are very good radios and are worth getting fixed unless the estimate is close to what you paid for it.

good luck, I hope this helps. if so, a good rating would really be appreciated. You can always ask me for more help if you need it. I have been repairing car and home audio equipment for over 17 years.

There are only three ways to get the code. https://www.fixya.com/support/r29874205-need_vehicle_radio_code ..

You can find a wiring diagram for an Alpine 7901 CD stereo online. You can search for the specific make and model of your stereo to find the diagram. Alternatively, you can contact the manufacturer of your stereo to request a diagram.

If there is no light in your Alpine 7294R radio, it could be caused by a few different issues. Some possible causes and solutions include: Fuse issue: Check the fuse for the radio and see if it has blown. If it has, replace the fuse with one of the same rating. Power supply problem: Make sure that the radio is properly connected to the power source. Check for any loose or corroded connections and fix them if necessary. Bad wiring: Check the wiring for the radio and see if there are any frayed or broken wires. If so, repair or replace the wires as necessary. Defective light or display: If the above steps do not work, the issue could be with the light or display itself. In this case, you may need to have the radio serviced or repaired by a professional. Dead battery: If your radio has a built-in battery make sure it is charged. It's important to check the owner's manual for troubleshooting steps and to identify the specific problem before attempting to fix it. If you are not comfortable with troubleshooting the problem yourself, it is best to contact an Alpine dealer or a qualified technician.

When you first turn on the Alpine CDE-153BT after restoring power, Demo Off displays for 30 seconds. While this is displayed, press Search/Enter (the center of the rotary ring). See page 9 of the manual. To permanently avoid the Demo Mode, see below. If you didn't press the button in that time, you need to enter the Setup menu. Press and hold Audio/Setup (the button is to the upper left of the rotary knob) for at least 2 seconds. Use the rotary encoder (knob) to get to General and press Enter. Navigate through the menu options to Demo Mode. Press Enter. Use the rotary knob to change the setting and press Enter to save. This is described on page 21. To ensure that the receiver does not return to Demo Mode On when the battery is disconnected, choose Quite Off, instead of Off. Then press Enter. (This is covered on page 22 of the manual.) The manual is available from Alpine Electronics here: https://support.alpine-usa.com/products/documents/OM_UTE-52BT_CDE-153BT_EN.pdf . I hope this helps. Cindy Wells

This is so so so f-ing ridiculous....I just can not find a picture of the inside of this Amp there is an orange wire on THE INSIDE OF THIS ALPINE 3552 DUO B CIRCUIT 4,3,2, AMP that is coming from 3 different places and tied to gether with a nother wire that was sticking out of the Amp my instinct tells me,... it's orange so probably needs power,,so I gave it power and the Amp come on but the light is orange not blue or green....and being on for a couple of minutes it shuts off ..I CAN NOT FIND A PICTURE OR WIRING DIGRAM OR SCHUMATIC the only pic I can find is to dam blurry to even see the wires uuuuuuuuhhhhhhgggggg

Some units are only in Japanese because they are specifically for the Japanese home market. There is a trick. Get a smartphone with the Google Translate App on it and use the camera feature to translate what is seen on screen. Look for Settings / Language. https://www.google.com/search?q=alpine+x9nx2+change+language+to+english ..

that is so easy, the glove box users manual fuse chapter covers that as does the factory service manual , and all 3 top online service manuals for sure Mitchells. DIY site. (oops no CRD there) 2007 Jeep Grand Cherokee WK 3.0Liter CRD(diesel) no country stated at all and guess what, the wring and colors are regulated by laws there.. we say color you said Colour so your car is not USA spec is it? what transmission is there. for sure diesel is special. for the transmission used most times. but seems same as my GAS, WK. but tiny 3L is not a torque monster, (good) gee remove tail lamp lens, see white (USA) backup lamp see color there clear as day but that goes to the BCM that runs that. not hard wired directly to the unstated, transmission PRNDL switch. not wired to R pin of PRNLD,. (TRS) then or now. I own 2010 wk, USA with NAG1 German trans, one of 3 transmission based on engine torque max. my Backup lamp is white/lt-green wire)_USA only. GAS only no diesel here. is your car 4wD ??? if yes wiring can be different. why not just wire up to the lamps rear, what could be more easy no books needed. my WK is complex. uses a network to command that on. the CAN_BUS, my gear shifter is a computer that only talks via CAN_BUS, and there is no PRNDL connections at ALL. and on the 2007 (same) USA> CRD ive no clue what is there. but CRD has 5speed transmission Mercedes Benz W5A580, aka 5G-Tronic.and NAG1 (usa name) nag = not american, but Germane? lol (seems yes) and this. WA580, W5A380, or W5A580. The W5A580 stands for:

• • W = Transmission using a hydraulic torque converter.
  • 5 = 5 forward gears.
  • A = Automatic transmission.
  • 580 = Maximum input torque capacity in Newton meters.

My WK has no CDR due to failing USA EPA, tests, USA> zero , what matters only is the lamp reverse color (BACK_UP) << jeep named. wht/ltgreen or how old SKOOL PRNDL is wired (not here) evolution of this 1 wire, jeep: PRNDL switch (on the transbox) to lamp rear. then PRNLD to BCM and BCM runs the lamps. then shifter is a puter, and has no wires to lamps ever.. just Can-BUS comms to the IPM brain and IPM runs lamps rear and vastly more. end history ,.2010 end. IF THERE WAS A FUSE IT BE MARKED REVERSE OR BACKUP. but sorry it is NOT THERE at all, in any fuse box cab /or;bay so that is why you posted, Look ma' no fuse.? MY CAR THE MAIN JB FUSE BOX HAS NO SUCH NAMED FUSE BACK-UP, AT ALL THE MODule THERE IS ELECTRONIC AND uses a current regulator (an electronic fuse) to do all. that. this fuse box is called in IPM integrated power module now you know if a fuse is missing like this one, the why. why matters most on cars, they are complex now. 2007 jeep made huge changes it is water shed year, that I do no like. buy the FSM book and read it. I have mine, buy the factory service manual for you country and car CRD see section 8w (means all wiring on this car is here) every inch. on mine 8w-51 -3 shows rear lighting, and path F source (backup) where it goes, my guess is PCM is IPM not present this car. the IPM is a computer too and is a save to the commands sent on the CAN_BUS network, from the shifter, puter. best way to do this is not rip dash asunder go to tail lamp, put wire there and 10 amp fuse inline to the CAM TOY' that why if you short it out by accident, or toy fails.? you do not blow up a $500 , PCM / IPM or BCM brain on jeeps never add things lacking a new fuse in line. power or lamps feeds need a fuse added. my year 05 to 2010 shows this in 8w chapter rear lighting there is no snap out fuse at all. it is electronically fused.

Yes, this happens all the time. Have a read of this Tip I wrote a few days ago. https://www.fixya.com/support/r29874205-need_vehicle_radio_code ..

Make sure that the television or and stereo receiver is not turned on to mute or the speakers are off settings. Ensure that the volume on the TV or the receiver is set up to an audible level. Try another disc in the DVD player and see if you get a picture on the screen if it works with another disc then there is something wrong with one of the DVD discs . Try using a different audio source through the television or the receiver
