Question about Pioneer Car Audio & Video

1 Answer

It seems that the sub-woofer doesn't work anymore. When I turn it a little louder the speakers start to crack. Also the display on the head unit is gone. So I can't change any audio settings to troubleshoot this problem.

    If it is the sub-woofer being dead do you think the installation of a non stock car radio would have anything to do with it? Also would that have anything to do with the display of the head unit being gone?

  • mmussar Oct 01, 2008

    The sub-woofer was integrated with the radio. Thats what the tech at tweeter said he was gonna do. So I'm pretty sure that the sub is run off the back speakers. Cause there is no amp. I don't think the back speakers are working either now that I think of it. I have a 2003 Acura TL if that helps.

  • mmussar Oct 01, 2008

    Ok thanks. Now would the internal amp in my radio being fried have anything to do with the display not working?

  • mmussar Oct 01, 2008

    Now what would I need to get them working? Would I just need a new sub and my head unit fixed?

  • mmussar Oct 01, 2008

    My sub is a bose. Its my stock sub that came with the car. I'm thinking something fried like you said. Whether its the wires or in the radio itself. The radio is under warranty so i'll just get a new one at no charge. I guess i'll ask the tech about getting an amp. I can afford replacing one thing but not a whole system or anything like that. If the radio's amp was the problem would buying a sub amp solve everything?

  • mmussar Oct 01, 2008

    Yes thats where is is I believe. So what is it exactly I have to replace the amp or the sub?

  • mmussar Oct 01, 2008

    So if I buy a new amp and get my radio re-placed all should work good? Actually better since it would be a better amp.

    I have a similar problem too. I have the avic-z2 with and external amp and powered sub. The amp powered the front component speakers. It sounded awesome and I was jammin out then all of the sudden the front speakers started popping/cracking and then went out and all i could hear the soft music out of the two rear speakers that are powered only by the head unit. I stopped, restarted the car and now the front speakers work but there is loud background noise/popping/ cracking and the subwoofer does not work. The front speakers work, but don't sound as loud and clear as before. The subwoofer does not work at all and I sent that back under warranty. I could disconnect the rca's from the amp for the component speakers and the cracking and popping stopped, so i am thinking the amp still works, and Like you said, maybe the sub fried my internal amp on the head unit. What do you think?

    well did you hook up an amp to the sub or did you run the sub off of the back speakers....? that answer will explain alot to me.

  • Jarrid Crandlemire

    ok thats the reason why your sub and back speakers are having a problem...when you are trying to run a sub off of a radio it puts out high frequency to the sub which is designed for low frequencys only.....that could be a reason why ur sub isnt working....but also another problem is that your internal amplifier in your radio is probably fried because the amp couldnt take the extra ohms....the sub basically popped ur amp (internal) and thats why its not working.

  • Jarrid Crandlemire
    Jarrid Crandlemire Oct 01, 2008

    also thats why your back speakers arent working

  • Jarrid Crandlemire
    Jarrid Crandlemire Oct 01, 2008

    well if the display dont work then your going to want to replace that anyways...and chances are yes that amp probably got to hot causing the display to also get to hot causing the malfunction of the will need a new car radio and if you want to run a sub off of it you will need an amp with the wattage (rms) of the sub. what kind of sub do you have....model #? depending on wattage of the sub amps can vary in price from $150 up to $300 ballpark estimate. also have a pro instal it i recommend best buy...they do a great job. and they know what they are doing. as for the sub i dont think you willneed to replace that as the problem lies with the amp not the sub or back speakers....might want to have the speaker wires checked for shorts because of all the extra heat...wires melt.

How do I hook up a sub woofer & speakers to my car stereo?

If you are replacing the existing door/deck speakers with replacements of the same size and not adding an amplifier, you will be able to use the existing wiring, making note of the positive and negative notation.
Subwoofers, on the other hand, require an amp. There are subs that have an integrated amp in the enclosure, otherwise you will need to buy a separate amp. Connecting the amp to your existing system will highly depend on what outputs your head unit (aka stereo) has. If it has pre-amp outputs, those can be run straight to sub amp. If there are not pre-amp outputs, you may have to buy a "high level" adapter that connects to the same head unit outputs as your speakers.

So if you bought enclosures that are premade AND had the speakers installed, you need to see if there is a cross over network installed in them

New in dash reciever, have sub woofers, they turn on but are not working

There are a number of issues that could be going on here. Go down this check list.

1. Check to make sure your head unit is getting power
2. Make sure the volume is up and that you do not have the unit on mute

The following list is if you have an amp (I assume you do if you have subwoofers).

1. Make sure the RCA cables are plugs to the correct outlet RCA's on the unit.
2. Make sure the RCA cables are not crimped at any point on the way back to the amplifier
3. Make sure the power and ground are good on the amplifer and that the remote turn on is functioning (this will turn the amp on).
4. Make sure the RCA cables are plugged into the right place on the amplifier.
5. Check the gain levels on your amp. This is a dial next to the RCA input. You will need a small flat head screwdriver to adjust.
6. Make sure the subs are wired correctly. If they are wired to the wrong ohms load they may cause the amp to go into protection.

If this doesn't help, you may need to get more specific in your next post.

Locked up sub-woofer cone won't move?

In theory your idea would work, however you risk damaging your amp by reversing polarity and the positive and negative wires from your head unit are low voltage so they wont provide enough current in reverse or normal polarity to free the cone of your sub. but here is something that you can try that is similar in concept.

Take a positive lead from your head unit and wire it to the negative of your sub. Now ground the positive terminal of your sub to the vehicles chassy using a wire. This creates a 12v-14v reversed polarity current that should be strong enough to (POP) the cone so to speak. hope this helps
