Why are my subwoofers only working with a few radio stations but not my ipod after installing new car battery?
So basically i just got a new car battery because my previous one was just about dead. The subwoofers work on some radio stations but do not work with my ipod. Help?!?
Hifonics amp: Needs mono signal but still wont work?
I ordered the Hifonics Txi 1008D amplifier and the site accidentally gave me the Hifonics Bxi 1208D amp, it was an upgrade so i said hey why not. So after installing everything and turning the radio on..i hear no sound from the subs. First thing that came to mind was defective amp (was not my first time installing an audio system btw). After two hours of trouble shooting and taking the HU out and checking the RCA and checking the grounds etc...i concluded that it was indeed the amp that was defective. So i called up the site and explained what happened and that i wanted a refund and the guy tells me that the amp needs a mono signal to work and that if i put a Y splitter on one of the RCA leads and plug it into the amp that it would work. I did that and still nothing plays. Am I missing something here? does the HU need to supply the mono signal? or do i need a different kind of Y splitter that changes the stereo signal to mono? If i can get this thing to work im gonna keep it ,if i dont then im gonna return it but not sure if they will take it back since i already installed it. Any help is greatly appreciated Thank You.
My amp got wet & stopped working. My sub was still hooked up & now isnt working either. whats wrong W/ the sub
electronic equiptment and water are enemies. it was a good battle, but your equiptment lost.
Why aren't my surround sound speakers working?
Here are some steps to troubleshoot this problem:Connect the surround speakers to the front channel of your system using the cables that are currently on the front channel. Does sound come out? Then the speakers are fine.Now use the cable from the rear channels to connect the rear speakers to the front channel outputs. Does sound come out? Then the speakers and wires are fine. Restore them to the rear channels for the other testing.Does your receiver have a separate fuse for the surround channels? If so, check that it’s not blown.Are you sure that what you’re listening to has a surround signal?Are you sure the receiver is configured to send signal to the surround channels?If the amplifier is not integrated with your surround processor (i.e., you have one device with HDMI in that has an RCA connection to an amplifier), swap the RCA cables that connect the processor to the amplifier. Do you hear sound in the rear channels (if you do, it should be what you’d normally hear in the front)? Did anything happen to the sound in the front (it might have dropped out). If the sound in the rear is still out and the front works, then the problem is the amplifier. If the sound in the rear works and the front is out, then the problem is either with your processor or the cables. Try replacing the RCA cables.If you got this far, you need to bring your gear to a service professional.
My subs won't hit in my car?
i hooked up my subs and they wil not hit. i have power running to the amp. everything is hooked up. when i play with the rca jacks on the amp end my subs flex in and out. so it is not the subs. the only thing i can think of is when i went to go plug my power wire in it sparked with my ground wire but my amp still turns on and i can here the fan running in it. the fuse never blew. any idea what is worng and how to fix the problem?
My speaker wire goin from my amp to my subs is getting hot and melting the sub casing even causing sparks?
The part where you said it sparks and that you felt a shock may indicate a problem other than small wires. There should not be enough voltage on the speaker wires to do this. After it cools, turn unit on but keep the volume as low as it goes. You might even turn the gain on the amp down. If the wire still gets hot, the amp may have a problem. If you have a multimeter, then check for DC voltage on the amp outputs. Most amps should read 0 volts with the volume down, on both the positive and negative outputs. There are some amps that will read a small voltage on the speaker outputs, but that voltage should be equal on the positive and negative with the speaker wires disconnected.
Why does my subwoofer smell?
I bought an Alpine Type S 12" dual 4 ohm subwoofers just over two weeks ago and have it matched with an Alpine MRP-M500 amplifier. I played it on low settings for a few days to break it in (about 5 hours) but when I turn it up loud on certain bass heavy songs, I can smell a burning electronic smell. Not like fire, but a distinct electronic burning smell.. is this normal for new subs? Will it go away?
I had new speaker and amp installed and now car won't start! Can this be caused by bad installation?
Oh these are always fun. Though I can't give you a diagnosis over email, I can tell you it is 100% possible to kill a car with a stereo installation. Your amplifier needs a signal to turn on or it will stay on always and kill your battery. Stereo install guys turn on the car and stab a test light into random wires looking for one powered only when the car is turned on. Unfortunately they have been known to splice into a CAN data bus. The CAN network in charge of communication for your security and locking could be disabled keeping your key from being authorized. Or the CAN network for your chassis systems can be shut down that deals with communication for your engine, transmission, and typically traction control. A CAN network is typically a 5 volt system but it suplies power in micro amps as it is only used for communication and not supplying a load such as switching a relay, lighting a bulb, or spinning a motor. Splicing into these to supply the relay to turn on the amp effectively grounds the circuit and does not allow for the digital signal to propogate. Sometimes it easier and they just blew a fuse while poking around with a test light, or shorted a harness by running a screw through it while mounting components. Had a lowjack installer put a screw through a floorboard and into a fuel tank once, cause a check engine light due to an emissions test, luckily it didn't burn down the car first. I have fixed at least a dozen of these problems on Benz's in the shop after a car got towed in from the stereo shop.
Why is my turntable only playing sound from one speaker?
If everything else is working on both speakers, the problem has to be somewhere at or before the input switch - jiggle it a bit and see if sound comes out from the phono, even momentarily. If so, a little contact cleaner sprayed into the switch may do the trick.Failing that, there’s a phono preamp circuit in your receiver (or maybe you’re using an external one if the receiver didn’t include one). Turn off the stereo and switch the R&L audio cables going into the receiver from the turntable. If the problem is now on the other side, you now know it’s not the phono preamp. If it stays on the same side, you may have a problem in the phono preamp circuit. Switch the cables back. If this is the case, it’d be cheaper to buy a new external phono preamp and use one of your spare line level (aka aux or tape) inputs to substitute for the faulty internal one (unless it’s under warranty).If you can easily access jacks where the cables attach to the rear or underside of the turntable, try the same “rotate-to-clean” and channel swap there.Now comes the delicate part, if these didn’t solve it. The thin wires in the tonearm have clips that attach to the phono cartridge, and sometimes a removable headshell as well. Inspect these connections for any oxidation, and burnish the headshell connections with a pencil eraser if you can. If you have fine needle-nose pliers, then try gently rotating or pulling off and pushing back on the little clips on the rear of the cartridge for a little friction cleaning (power off for all of this, BTW). Be very gentle since those wires can break easily.One last possibility is that some turntables have some metal contacts under the tonearm base that mute the signal from the cartridge during tonearm cycling (return from the end groove), and these can sometimes also get dirty or (less likely) bent where they don’t make contact.The phono cartridge MIGHT have a faulty coil or internal connection, but this is rare. If so, replacing the cartridge is your only option. Needle Doctor is a good place to find a replacement (but if you get the same one, save the original stylus as a spare, it’s almost certainly just fine).There’s a free website, Vinyl Engine The Home of the Turntable that offers user guides and service manuals for hundreds of turntable models, you might want to see if there’s a known manufacturing problem or common issue in their forums as well.After doing all this, you now qualify as an expert (if you worked carefully and paid attention)!
