SOURCE: Amplifier and subwoofer

Yes, it should have little trouble. You will be best to keep it 2-channel and get another Sub. then run both. if you bridge it you will blow your 1 Sub. DON'T FORGET to put a in-line Low Pass Crossover in front of the Amp. OR any Sub.(one for each if you do go for 2) as they were never made for the high frequencies. An adjustable one is best for fine tuning. In thory you have a 600 watts buffer that way. If you do it Mono you are 400 watts over. If you want to go Mono you will need over 2000 watts on the Sub. end to turn it right up. Oh and some good ear-plugs if you want it loud whilst you are inside the car.

My subwoofer shows red light and no sound


Your subwoofer amplifier has DC Offset, meaning it has a damaged amplifier. Until that is repaired, it will not turn on.
If you are interested in having your LG repaired, please look to my website at audioserviceclinic.com. Thank you.

THERE IS NO SIGNAL COMING FROM THE SUBWOOFER, IT IS CONNECTED TO A SONY AMPLIFIER IN THE SUBWOOFER JACK, AND CONNECTED TO THE SUBWOOFER IN THE LOW LEVEL INPUT. THE SUBWOOFER IS CONNECTED TO THE MAIN, AND...


With everything connected correctly there could be a couple of possible problems:

1. If your receiver has on screen display capabilities, you may need to turn the subwoofer output "on"
2. If your subwoofer has speaker wire inputs/outputs, you could run speaker wire to it, then to your speakers & test if the subwoofer is working... hence verifying that the receiver has a function to turn the subwoofer output on/off
3. The cable between the subwoofer & receiver could be bad. Try another cable.

Good luck!

I have a ly1440 amp how can i wire it to my hk15x2


This subwoofer has (2) 2 Ohm voicecoils.
Which means you will only be able to wire a 1 Ohm or 4 Ohm configuration for your amplifier.
The Model # you listed for the amplifier is not a valid one.

If your amplifier is 1 Ohm mono stable...
you wire both (+) Sub to amp (+)
and both (-) on Sub to amp (-)
This is PARALLEL wiring and lets the amplifier SEE a one ohm load

If your amplifier is NOT one ohm mono capable - your only other possibility is a 4 Ohm load.

Wire from (+) on amplifier to one (+) on the sub
Then Wire from (-) on amplifier to the OTHER terminal's (-)
You will have one (+) and one (-) left on the subwoofer - wire them together.

This is SERIES wiring, and nets a 4 ohm load for your amplifier.

There is no other configuration for wiring one Dual 2 ohm sub.

Ok . i have a pair of crossfire subwoofers, @


Your amplifier is 4 channel... and only 2 ohm stereo capable.

You will get the most power putting 1 subwoofer wired in parallel on each BRIDGED channel.

This will give you a 2 ohm stereo load.

Both + on 1 subwoofer to + terminal on amplifier bridged channel 1
Both - on 1 subwoofer to - terminal on amplifier bridged channel 1

Both + on 1 subwoofer to + terminal on amplifier bridged channel 2
Both - on 1 subwoofer to - terminal on amplifier bridged channel 2

Which terminals to use


if your amplifier is 2 ohm mono stable - you can wire them in parallel.
Put a piece of wire from one + terminal to the other + terminal on the subwoofer.
Then do the same to the -.
Now pick one pair of teminals from the subwoofer and wire it to the amplifier. (one set of subwoofer terminals will have 2 wires each).
If you reply with your amplifier make/model, I can tell you the best usage.

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.
