Everything is connected and its getting power but don't wanna play anything out the subs

Recheck your connections from deck to "non-sub" speakers. Are you using an adapter from deck to vehicle wiring harness OR are all wires individually connected?

Make sure all outside blinkers are flashing at one speed, if not check the bulbs and all connections, If that doesn't work check flasher

How old is he ?

I don't recommend it. It may work good during low volume, but from experience, you will only turn it up so high before it trips the protect light on the amp since it's drawing too much current due to extra speaker(sub), then you have to turn off the radio and turn it back on to get it working again, it gets annoying. I recommend saving up for a mono amp, it will keep your system sounding clean and clear. the setup you specified will work, but it's not recommended. Your amp may run hot as well.

connect from speaker out to the speaker driver

you can blow a sub out when they are overpowered as well as underpowered. Distortion is the main reason thing go out. distortion occurs when you have the volume n the head unit up all the way and the gains on the amp are up all the way. always make sure the bass plays clear and you should be okay

Yes and Yes. If bypassing that noise filter, has no effect your subs could have blown.

Hello again debrahood196,

Your KAC-5204 amp is only rated to put out 60 watts per channel and really cannot push very hard. If your subs are the KFC-W110S, they are 8ohm subs and you will get better power from the amp by using the bridged connections, positive (+) on the left channel and negative (-) on the right channel. Wire both positives and both negatives from both subs to the bridged connections and the output will be 150 watts into 4ohms. Giving each sub 75 watts should make them push a little harder.

first check that the subwoofer function on the actual head unit is turned up,second check that the gain on the amp is at bout half way then check that it is on a lp (low pass setting)
then check that the boost on the amp is turned up.
please leave feedback.
cheers

The first thing to try is disconnecting ONE of the two subs. See if you get more bass with a single sub than with both. If you do, re-connect the second subwoofer, but reverse the (+) and (-) wires.
