Sub Wiring Help Options

[Nick205]

I am putting an Infinity Basslink powered sub in the trunk of my celica. But the sub will not power on. I used a voltmeter and the sub has power going to it but it won't power on. However when I put the positive battery cable in the remote spot on the sub it will power on. Is it safe to run it with the battery cable in the remote spot? Can I run the remote cable and the power cable at the same time? Please help!!!!

Your problem is obvious. Your remote is not getting power, or not ample power. Check your connections, and fusings.

Where did you run your ACC off of?

EDIT: Uh... This may need some clarification...

Constant (+) = Battary
Ground (-) = Chassis
ACC/Remote (+) = ignition switch operated positive source. (like the radio fuse) preferably with a toggle switch between the source and the AMP to have the manual power option of turning the amp on and off.

It is not the remote wire because the sub has an auto turn on feature that will keep it on all the time as long as it is getting power. If I plug in both the (+) battery and the (-) Ground and use the auto turn on it still doesn't work. And all my fuses are good. Any other suggestions?

Auto turn on?

DUDE!! you have to wire it to do that . by wiring the ACC/REMOTE to a positive(+) source that is powered via ignition. THAT'LL MAKE IT "AUTO TURN ON" WHEN YOU POWER THE CAR.

If you bridge the constant and the acc than via the battery then your amp will never turn off; at least not until the battery is dead.

-sigh-

Constant to battary
Ground to chasis
acc/remote to the radio fuse or the cig lighter or something.

EDIT:

However when I put the positive battery cable in the remote spot on the sub it will power on.

Can I run the remote cable and the power cable at the same time?

both the "power" cable and the remote cable are positive sources. the "power" cable goes to the battary because it's fine with CONSTANT power, the ACC goes to a positive source as well, but does NOT need to be constantly supplied energy.

For example, your radio turns off when the car turns off. This is because the ACC power source to the radio has been shut off. this powers the radio off. However, you keep your programed radio-stations, and the time in your clock, because the CONSTANT power source is still connected.

Get it?

I understand constant and acc. I used test light and the remote wire does give off power. I think my problem is a loose battery connection with the sub but I can't take it apart to find out.

...The Auto turn on feature does not need the remote wire...

okay, my fault. I've never head of such a product that automatically turns on w/o being signaled to do so, nor products that will allow it to have power ports that are not required to have power to them, however if this is indeed what you have, then good luck geting it to operate sir.

I am trying to run the remote wire from the power antena wire in the back of my head unit. Is there any other cable I could splice the remote wire with to give the sub power?

PM replied.

The Power Antenna feed is not a constant power source. Therefore will not supply your remote with the power needed.

Take the power lead from the Red wire on your aftermarket head unit. This is the ACC power for the unit. There will be plenty of power to supply both the amp and the head-unit.

A lot of head units have a wire designated as "remote" and it is often blue or blue with a white stripe (at least from all the decks I've used). All the remote line does is send a low power signal to the amplifier that tells it "the cd player was turned on" so the amp will power up. The signal is like 1/4 or 1/2 an amp and if you put your positive battery connection to that, you probably won't like the result.

As it was pointed out, you don't WANT the sub to be on constantly, you want it to go on and off with the cd player (what you called auto on/off feature), so you need to use the remote line from the head unit to the amp, not from your power antenna.

[D-Man]

Remote power is BLUE/WHITE or BLUE/BLACK, (pos and neg respectfuly) Plain BLUE is usually power antenna (IME). Secondly, not all head units have this feature, and finaly all it is is a resistor pluged into a passthru for the ACC line of the head unit. It's all the same source. also note that different harness brand-names CAN use different colors for different things. Some items are so universal, however, that they'd be dumb for not making standard issue.

Thanks for the help guys. I finally got it to work. I switched the remote wire to a blue and white wire and what do you know it works.

Yay!!

Now post pics, and then [/thread]
