Question about JVC KS-AX3500 Car Audio Amplifier

1 Answer

Hooking up only one sub, no sound.

This is a new install of the JVC ax3500 amplifier, the woofer has been tested on another amp and is working, the woofer doesnt produce any sound. It does however make small vibrations when a lot of bass is being played. I tried changing the RCA cables to different positions as well as turning the HPF and LPF switches on and off and one on one off, all different possible combinations.

Why would my amplifier turn on but not send anything to my sub-woofer?

Try using a continuity tester turn the amp on as normal play the head unit and see if you get a reading or you can try using a different sub woofer if the problem persists I could be your amplifier then

Im just hooking subs. to my amp , so do I run my woofers to the terminal that say's sub or to just the other speaker terminals.the thing is I have two ssubs. and one sub terminal

If you want to use two Kicker Coaxial or Component Speakers on a single
channel of your amplifier wire the speakers in series. This will improve the sound quality, lower the total harmonic distortion and
lessen the thermal load at the amplifier. This may prevent an amplifier from shutting down, due to over-current protection definetly on the SUB terminals as this channel provides the better bass response........

How to measure watts

You need a Volt Meter and an Ohm Meter. P = VI & I = V/r, so Power = (Volt^2)/Ohms .

You can get the ohms by hooking them up to the subwoofer input wires, and you get the volts by hooking up to the amp output terminals/wires. Although, amps will put out different voltages for different frequences, this should give you ballpark estimates.

sounds like you need another amp, if the amp has a speaker already connected to each channel, you have no open channel to connect a sub-woofer.
Some years ago I seen an amplifier that was designed to use 3 speakers on 2 channels. what they did was had a speaker on each channel and then they bridged the 3rd speaker across it. That amplifier was designed for this configuration, unless you have an amplifier like that you should not try it. It may result in smoke from the amp.

Hooking up a new 8" woofer speaker to my amplifier

If I'm reading the amp manual right, you should be able to connect the amp in 3 channel mode. To do this:
  • Connect both left door speakers in parallel to Ch A Left.
  • Connect both right door speakers in parallel to Ch A Right.
  • Bridge Ch B and connect it to the new 8" sub.
  • Set the Ch A LPF/HPF to HPF.
  • Set the Ch B LPF/HPF to LPF.
This should allow you to run all 4 door speakers and the sub from the amp. It will also automatically route non-bass to the door speakers and "only bass" to the sub.

Amp light is on but no power to my subs!

Hi There.

When you say the 40 Amp fuse blew. Was it your mains battery fuse or was it the fuse on the amplifier? If it was the fuse on the amplifier then you may have hurt the amplifier. The Kenwood KAC-8101D is a 1000 Watt monoblock amplifier. Therefore if you say that 1 of your woofers is not playing, then it is almost certainly blown if you are sure it is connected correctly. Try disconnecting it and only running the woofer that tries to play. If this woofer is still working correctly, you will notice a drastic drop if the sound of your bass. The reason for this is because you have changed the impedance load on your amplifier due to the fact that the other woofer is not working. Have your working woofer checked and replace the faulty woofer then you should be banging again.

Hope this helps!!

Amp help

it might not be the amp that is not working it could be the sub or sub's. Try takeing a sub out of the box and look down the hole in the center of the magnet on the back of the sub and look and see if you can see any wire's or any thing that has come unwound in the sub and if you do see wire's then you have blown your sub. If you dont see any wires then you could completly disconect your amp for 20 to 25 minutes and then plug it back in and see if that fix's your problem. If none of this works then you can take your amp to an audio store and have them test the circut board in your amp.
