Re: amp on but no bass

1st make sure the speakers are not bad, check th eimpedance with a multimeter, the voice ciols should read 3.9 to 4.3 ohm's. if any of your subs are below this most likly the subs are bad. if they are ok make sure the ground for the amp is good. now the last thing is the amp. try another pair of speakers, even if it's smaller ones, just make sure they are 4 ohm speakers, keep the vol. very low during your test. if the other speakers do not work then have your amp serviced or replaced. good luck

Kenwood KAC-8103D on and off problem

it sounds like the power wire might be grounding out somewhere that you dont know of it could be by the fuse link so I would say put electrical tape on any exposed wire on the fuse link first if that don't work try change the power wire.

Just woundering if i could bridge one sub to front and one to rear the subs are kenwood w3514 dvc subs the amp is kenwood kac-x501f

Hello bigmac208,

Yes, that would be the best connection for both the subs and the amp.

I'd wire the sub voice coils in series since the amp will not be stable at 2 ohms when the channels are bridged. The power will be somewhere between 100-200 watts RMS to each sub. While it's not pavement pounding, it should provide pretty good bass, especially if you tweak the crossover and boost settings for best bass response.

Hope this helps.

Why does my KAC-8404 cut off at high volume bass?

amp 101

1/0 wire to the amp or the amps will loose power

check the connections mainly the negative

wiggle the wires see if you get a cut out or not

a cap will help you give constant power to the amp and not allow them to drain on long bass notes

hope this helps

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!!

It should be better to use the Pioneer GM-7200M Amp with your subs.

For 8 ohm setup hook up this way:
Amp out+ to Sub1 +
Sub1 - to Sub 2 +
Amp out - to Sub2 -

For 2 ohm setup hook up this way:
Amp + to Sub1 +
Sub1 + to Sub2 +
Amp - to Sub1 -
Sub1 - to Sub2 -

Amp not powering up??

the sub amp may be damage, shorted. you may have a wrong speaker hook-up the first time you use it. too low impedance may have damage the sub.
