Sony AMP/Subwoofer Problem

Hello, i was wondering if i could find some help here, i have a sony amp and sony subwoofer, for about 1 and a half years now i had no problems with this combination, but lately everytime i play music, a game, a movie, the bass of the subwoofer will cut out, then it will come back in, but it never happens in the same spot or with the same song, it just happens randomely. I'm not sure if the problem is the sub or the amp. Others speakers connected to amp do not have any problems, although the subwoofer has a specified plug in. I have read places that maybe the amp gets to hot and causes this, but that cant be the case because it hapens right away when the amp is turned on.....im stuck on this problem, the warranty is done, i just need to know a good direction to go, do i ned to replace some something inside the amp??? or sub?

Thanks so much for you time!!

For me it,s the amplifier had a problem, if your amp is a 4 channel output the rear 2 channel is for sub woofer driver. if it is a PWM amp and you laod a 2 omhs into sub output maybe that's the cause to burned transistor output because 2 omh stable is not ideal to used it's always 4 ohm to avoid some trobles

There are many parts inside of the subwoofer box that can cause this problem. First you will need to remove the subwoofer speaker from the subwoofer box completly, there should be no wires from the subwoofer box attached to the speaker. Take any single one-point five volt flash light battery (1.5 volt flashlight battery) and connect the side of the flashlight battery that mark minus (-) or negitive to the side of the subwoofer speaker terminals that mark minus (-). Next connect the other side of the flashlight battery that mark + to the other side of the subwoofer speaker terminals that mark + (plus or positive). When the + wire of the battery make contact with the + terminal of the subwoofer speaker, the subwoofer speaker paper should move forward away from the speaker. This forward movement of the speaker means that the speaker is good and that it is also in phase. Next you will need to connect the - minus and the + plus wires from the battery terminals permanently to the subwoofer speaker terminals. By removing and re-connecting the two wires from the flashlight battery to the subwoofer speaker terminals which is the - minus wire from the battery to the - minus speaker terminal and the + plus wire from the battery to the + plus terminal of the speaker, the speaker paper should move forward and stay forward and when the speaker move forward try moving the subwoofer speaker paper forward and backwards two to three times you should not hear any carckling coming from the speaker. Make sure that when you are moving the subwoofer speaker paper forward and backwards the wires on the battery and on the speaker terminal are not moving. If you hear any carckling comming from the speaker when you are moving the subwoofer speaker paper. THIS MEANS THAT THE SUBWOOFER SPEAKER HAS AN INTERMITTENT PROBLE OR THE VOICE COIL WIRE IS BROKEN. Check all subwoofer wires, plugs, jacks and wire connecting points inside and outside of the subwoofer box for good connection. When the speaker is playing it will vibrate the box. This vibration can cause wires, plugs and jacks connections inside and outside of the subwoofer box to come loose or not making proper connection. A loose connection in side of the subwoofer box or outside of the subwoofer box can cause this problem. Make sure that electrical power cord that brings the electrical power from the wall outlet to the subwoofer jack is good and it is also a good idea to replace the electrical power cord. Make sure that the electrical power cord is push all the way in, into the subwoofer jack and make sure that the plug on the other end of this same subwoofer power cord is push all the into the wall outlet.If you use an electrical extention cord to bring power to the subwoofer you should use one that has a ten gauge wire or one that is large. You can find a good electrical extention power cord in a local hardware store or you can locate a good electrical power extension cord at a radio shack store. This electrical extention power cord must able to carry 15 amps of electrical current continously. A small electrical power extention cord can give your subwoofer low voltage which is any electrical wall outlet voltage which is below 108 volts. Proper electrical outlet voltage should be between 110 volts and 132 volts. The amplifier inside of the subwoofer box could have loose transistors, I.C.,s resistors,capacitors, volume control adjustmens and even a broken or losse copper trace which is use for carring the electrical voltage and current. If you check every thing that I have mentioned above, then the amplifer inside of the subwoofer box is defective or broken. MAKE SURE THAT YOU REMOVE ALL THE ELECTRICAL POWER FROM THE SUBWOOFER BOX BEFORE YOU REMOVE THE SPEAKER!

It is probably the tweeter, inside the Sub. it's the small ceramic disk between the cone magnet, and the speaker. id this thing is cracked or broken, this will cause the problem. if this is not it, then it is a problem with something in the wiring, and the only way to rectify it is to buy a new sub. Sorry due :(

How do I connect a Sony xplod 1000 watt 2 channel amp to 1 10" dual 4 ohm voice coil 1500 watt planet audio subwoofer?


Connect one voice coil to one channel of the amp. Repeat with the other voice coil. Do not bridge the amp as your only choices would be series which would be an 8 ohm final load and cuts the amp power in half or parallel wiring which results in a 2 ohm load and very few Sony amps currently made can handle being bridged to a 2 ohm load.

How do I hook up subwoofer sony cxs-gt08hp


NO!!NO!!NO!! Dont hook up just a sub to rca outputs. they run at around 2-3 volts and maybe 1 watt. the difference in the settings is for a sub amp(sub) or a amp for mids and highs (amp). the only way you will not need to run an amplifier is if you get a powered subwoofer, as these already have an amp built in.

Sony str-dg800. Pre-amp out has no signal.


Hello. Jacks you are refering to are surround preamp out only. If you want full range audio out use video 1 audio out or video 2 audio out. The set does have a mono subwoofer out. You could have to go into the menu and turn it on but that is where you are to connect a subwoofer to . Larry's Electronics. ledstiles@hotmail.com

What amp do i need for Sony Double XS-L124P5B 1300w each?


Most professional car audio installers and manufactures say that to get the best sound out of your subs, you should run half of the RMS wattage listed on the speakers, which in your case would be 1300w for both which is kinda up there, but you can find a 1200w amp and even a 1000w amp would work great, just make sure that the amp has true wattage listed because they have a habit of over rating them until you read on it later. Another way of going about it would be 2 amps, 1 for each speaker, which would be smaller amps, but you would have to make sure both are getting the same amount. Hope this helps.

Amplifier turns on but not the subwoofer?


Hello thedj3214,

You can find the color codes for a 1999 Buick Regal here. There is no dedicated amp remote wire. Neither is there a power antenna wire.

You could use the 12V "switched lead (yellow) from the radio or any switched 12V lead directly from the vehicle fuse box. I'd wire it through a dash mounted toggle switch so as to be able to turn the amp on and off manually.

The Sony 2150GSX is a 2-channel amp with the speaker terminals on either side. You do not want to ground the subwoofer itself, only the ground terminal should be connected to bare metal on the vehicle chassis or body as close to the amp as possible. The ground wire does not need to be run to the negative battery terminal.

A ground on one of the speaker leads will probably cause the amp not to power up. A ground on a speaker wire usually activates the amps protection circuit, causing it to not operate until the fault is corrected.

Hope this helps.

Is amp big enough for speakers


Hello,

To run 2 subs, the amp would be a little small. The subs will run OK, they just won't be very loud.

It's usually better to compare and match up the RMS power rather than the peak power. The Sony XS-L10P5B sub has a peak power handling figure of 1200 watts, but the RMS is 300 watts. The Sony XM-ZZR3301 monoblock amp puts out 1100 watts peak, but only 330 watts RMS. They would work great together, 1 sub, 1 amp. But if you add another sub, each one would only be getting about 165 watts. They'd work OK, just not as loud as they could be.

Hope this helps!

What do i need to install a subwoofer


Here's what you need:

1) An enclosure for the 8" subwoofer.
2) 8" subwoofer.
3) Amplifier to power the sub.
4) Amp wiring kit.

Your Sony has two sets of preamp outputs so make sure that your wiring kit includes a set of RCA's.

What voltage required to power a sony subwoofer


Hey,

I just got one of these units, the SONY SS-WG990.
The RCA cable is direct conection to the speaker.
It requires external AMP.
The other cable is just for the system switch and LED.
If you just have this unit, all you need is an AMP to
feed it.
