If you are referring to a powered subwoofer, the remote lead hooks up to your head unit at the "Amp" or "power antenna output" If you have a factory radio you will need to find an alternate source of power. Make sure it switches on only when your ignition is on.

I have a kenwood kac1502s amp in my truck and it works good until i put the truck in drive and start to move and the amp red light flashes 2 times and the sub speaker shuts off put the amp stays on until i...


compare the voltage to the remote turn on wire to the amp when parked and when in drive. the wire may be hooked to the wrong wire at the head unit. the wire should be hooted to a specific amp on wire, power antenna wire, or if its a stock head unit it should be hooked to a 12 volt on source.

How to wire sreaker system


this is the same as a home speaker system, if installing an amp and sub you need to make sure you have a pre-out on your cd/tape/radio head unit. this will look like a red and white hole usally with l and r on it,
you will need to run a male phono to phono lead from the head unit to the amp, You will also need to run a fused live 12v from your battery to the amp live input (red wire) and a remote (usally blue) from your head unit to the amp (make sure you run the live ond remote on opisite sides of the car to the phonos as they can interfere with each other).
you also need to run an earth/ground to your amp, this must not be to long, i normaly just un srew a screw in the boot and connect it to that.
once this is done you can wire up your sub to the amp making sure to match - to - and + to plus.
hope this helps

You shouldn't have to buy y connectors. The sub output on the back of the sony head unit is for bass output that goes to an amplifier & then to a sub. The RCA's on the harness will be just for Stereo sound ( left & right ).

Hey i have 4 p1 10" subs and when i turn it up loud it shuts off what could be the problem


Your head unit and the amp are turning on at two different times. Go to Radio Shack or an electronic component retailer and ask for a small 500 to 1000 micro farad capacitor (about a half inch in size). Then connect the side of the capacitor with the line on it to the small remote turn on that is connected to your amp. Next shorten the lead of the other end of the capacitor and connect that lead to your amp where the wire was connected. This causes your amp to take longer to turn on and stops the annoying pop. Good luck.

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

Power off issue


Hello octoberburni,

No it is not normal for the amp to stay on when you turn the ignition off. And yes, it will definitely drain your battery if this condition is not corrected.

Use a multimeter set to volts and check between the ground connection (right connector) and remote turn-on connection (center connector) on the amp itself. You should have approximately 12V when the ignition and your head unit is on. And 0V when they are off. If you measure voltage when the ignition and head unit are off, either the incorrect wire is connected to the remote terminal, or the defect is in your head unit. If you measure OK, that is voltage present when ignition and head unit are on, and no voltage when they are off, then the problem is most likely in the amp itself. If you find voltage on the remote wire all the time, check to see that it is coming from the correct output from the head unit. Most aftermarket head units use a blue or a blue/white wire for the remote amp turn-on lead. Many (most) stock OEM receivers do not have a remote amp turn-on lead. But they may have a power antenna lead which will serve the same purpose. In any case, just insure that the correct wire is connected to the amp. It should have voltage when the head unit is on and no voltage when the head unit is off.

In either case, if everything else is still working with the amp, you can simply wire in a manual toggle switch to turn the amp off or on whenever you desire. A SPST (single pole-single throw) toggle switch is what you need. If the problem is in the head unit wire, put the toggle switch inline with the remote wire and mount it somewhere handy on or near the dash. If the problem is not in the remote wire, you'll need to put the toggle inline with the main power wire, the one marked "12V" (left connector) on the amp. In this case, you need to make sure that you have a heavy duty toggle switch, one that will handle more amps than your primary fuse. You may need to look under the hood for the fuse to check it's value.

Hope this helps.
