The Sub gets it's output from the pre-amp circuit, whereas the components get their output from the main amp circuit in the unit.

Sounds like it could be a short in the speaker wiring or a blown speaker. Check all wiring to the speakers.

Check all speaker wires from the unit to the speakers.

First check that each pair of speaker terminals at the speaker end is not touching. Or, a wire fell of 1 terminal to rest on another.

Best way to check if it's a blown speaker or a wiring short, is to disconnect all speaker connections ( at the speaker end ) making sure the disconnected wires don't touch each other or any metal in the car. press the reset on the unit and power up. If the unit powers up ok, then its a blown speaker.

Otherwise it's a short in the wiring.

If it's a blown speaker, you can connect 1 speaker at a time and the blown 1 will send the unit into protect mode again.

If it's the wiring, disconnect the unit from the wiring and use and ohm meter to check each pair of cables. A reading suggests a short.

If you don't have an ohm meter a battery and bulb will do. This method usually works on a short.

If you have no joy with either method, take each speaker wire in turn and check with a source of earth (anything metal connected directly to the body of the car, cigar lighter main body when pulled slightly out is good)

Wiring a subwoofer in a 2012 civic coupe


Run the 12v power wire (usually the longest wire in the kit, mostly red, typically ranges from 8 gauge to 0 gauge) from the battery through the firewall and then to the amp. You can find a hole somewhere in the bottom right of the firewall. Don't connect the power wire to the battery or the amp just yet. Find a solid metal ground somewhere near the amplifier. You'll need to stay within 2-3 feet of the amplifier to maintain the best ground connection. A way you can do this is pull up the carpet and scrape the metal until it is bare metal with no paint left on it. If the amplifier is to be mounted in the trunk, many times bolts from the suspension can be found directly above one of the rear wheels. These suspension components usually bolt directly to the frame, making them an ideal grounding point.
Pull the aftermarket CD player out of the dash. There is a blue wire with a white stripe hanging out of the back of the deck known as the remote wire. The remote wire is a simple 12v signal that the cd player outputs to tell the amplifier to turn on. Take your remote wire that came in your amp kit and splice/solder it onto that blue-whitestriped wire and run it through the dash and then along the door jam. While you have the CD player removed, plug the RCA white and red plugs into the back of the deck where it says "Subwoofer Output." If your cd player does not have a "Subwoofer Output", or if you are using a stock cd player, you will need a device called an inline converter. It's a small box that has 4 input wires and the 2 necessary RCA output that will run to the amplifier. It takes the high level speaker voltage and drops it to a low level signal the amplifier can process. The 4 input wires can be connected to the rear speakers (+ and - for left and right)
Run all the wires straight back to the amplifier.you should run the power and remote control down the right as factory speaker wires run down the left due to fire risks if the power cable shorts out and you have your speaker cables down the same side it will blow your headdeck (cd player). RCA cables should be run down the center of the car as RCA cables can pick up sounds from wire looms and also air con vents power wires. se Speaker Wire to connect subwoofers to amplifier. Gauge isn't extremly important here, as long as the wire is copper, the resistance-per-foot is in the milliohm range, meaning there will be miniscule, if any, voltage drop across the wire.
Put a fuse into 12v wire in the engine bay no more than 0.5m away from battery. If your amp kit came with an "inline fuse holder", you'll want to find a nice location to mount it in your engine bay. Once it's secure, cut a length of the power wire to reach the fuse, and connect it to one side of the fuse holder. The other side (the side you just cut) is stripped and connected to the other side of the fuse holder.
Connect the power wire to your battery. There's nice ring connectors and even new battery terminals you can buy (and sometimes come with the amp kit), that make the battery connection much more solid, and looks better too. Lastly, connect the battery cable to the amplifier. Then under the hood clamp the wire down to the battery. A word of warning, sometimes you'll see a nice big spark the first time you touch the power wire to the battery. Don't worry about it! This is the amplifier charging the huge capacitors contained inside.
Do not turn up the volume or gain too high or you may produce clipping in the subwoofers. This is where the output of the amplifier peaks and stays there for a split-second. This is bad for the subwoofer because it holds the cone (the big circle part!) in it's fully extended or fully compressed state for the duration of the clip. Not only are you not producing a single decibel of sound during this microsecond, but you're also working the voice coil very hard and damaging it. A good rule for beginners is to play a nice loud song of your genre at your cd players 3/4 volume setting. Now, with the gain at zero, turn it up until it's obvious that it isn't getting any louder. The gain knob isn't a "volume" knob by any means. A gain knob should usually never be at it's full position.

Light stays red, will not switch to green. I hear no sound from the subwoofer


Red Light Constant On - Means the Amp Is Not Turning On - Signal Problem or Most Likely Burnt / Non Working Components - There Is A Guy On Ebay Who Repairs these amps.

I just brought clarion cd player had it fitted by vauxhall dealer and when i put the key in the ignition turn key to aux cd wo'nt come on but when you turn the key to start engine cd player...


Sounds like the unit was not wired into the car properly..the dealer needs to make sure that the switched lead that they connect the red wire from the radio to is hot when in both run and aux(accessory) positions on the ignition switch...it sounds like they may have wired the switched lead to the wrong accessory lead

How to tune properly


make sure your speakers are wired to the amp with correct ohm load, turn gain, bass boost all the way down on amp, zero out your equilizer on the cd player and turn it all the way down then start raising volume on cd player., when u can start hearing music thru the subwoofers adjust the cd player volume till the sound from your subs is at its peak without any distortion. then start raising the gain on your amp till you are happy with the sound. It gives you the optimal signal strength coming from the cd player and the smoothest sound.

Unit was working for a couple of months. Then I noticed some cracking sound coming from it then the sound stopped coming through. It came back for a few minutes then it has not worked since. This is all on...


sorry, but from your description i dont think there is much help for your sub. unless its new and under warranty. that sounds very typical of a dead sub. i have had a bad run in with sony products just quiting only after a few years. i try to stay away from anything with the word sony on it. a short list of the sony products that i can rememdying only after a year or so cd boom box (3 of the same one) sony 19" tv, sony handi cam (video camera two weeks after warranty peroid), component cd player, alarm clock radio.... the list is longer but i will stop. sorry for your trouble.

Volume goes away after being on for a few mins


It seems like your problem is what in the Army Signal Corp. we called "internal breakdown of components", the problem is in the audio output transistors, heat related , it works okay for a few then as soon as it starts to warm up it shuts down, the unit stays on but has little or no audio output. You will have to pull it and bring to a tech for repair or replace it,sorry.Please don't forget to rate, Thanks

Not satisfy with the sound of my system


This Unit has got a 4x60w amp built in.

On it's own the subwoofer will not work, you need to buy a Monoblock amplifier, a wiring kit and a set of RCA leads to run it.

The RCA leads plug into the SUB output RCA sockets on the back of the headunit.

The OEM speakers in your car will not be of great quality, so it would be wise to change them. If you do, you need to buy speakers that have a rating of no less than 90watts, any thing less and they will sound distorted.

Any car audio shop will be able to help you select the right size and rating to suit your car. They may even fit it all for a charge.

Hope this helps

Connect audio components for recording Cassette to CD


Try this since you do not supply model numbers. If your receiver and CD have digital audio connector (coaxil or fiber) hook the receiver output to the cd input.

If you do not, see if there is a spare set of RCA jacks for output. If not, just hook up the cd player in the cassette jacks-there is always a cassette in and out-and hook your cd player to an auxillary input or use the cd player input.

Remeber though, cassettes have inherently more noise than cd so your cds will not sound like a pre-packed cd.
