I have a Kenwood KAC-6402 amp & need to find out the function of each of the 10 pins in the speaker level input. Do I just need a schematic of the amp itself to figure this out?? If so, where could I find one, & if not, how do I go about determining each pin's function??? Thanx Alot!!!
You could open the amp to see if the wires are labeled at the circuit board end. Other than that you would need a wire diagram or someone to give you their harness that they are not using. Should be a lot of them kicking around since most people use RCA's.

You can run the speaker wires to the speaker level input on the amp or i believe you can run another set of speaker wires spliced into the existing wires in parallel to the speaker level input along with the speakers that are already hooked up if you are using the amp for a sub or other speakers that you have added to the existing system.
either the wiring your running is short circuting,or the amp is shot, or the subwoofer is shot, try hooking the same speaker up to the other amp. along with the other speaker to the other amp, see if the same thing happens.
Have you connected the rca plugs to the radio or amp directly? If you've connected it to the radio make sure that the input level controls are adjusted AND available on that model (it will say AUX, INPUT, SUBWOOFER, REAR, etc.) Connecting your mp3 player directly to the amp will not have enough juice to hear sound you need to connect it to the radio first.
Its not pulsing, its called clipping. The sound is being clipped due the amp being pushed past is power capacity and distorting the signal. This will damage your speakers very quickly. No amp should be turned more then 3/4 up. If its not loud enough you need to purchase a larger amp or be comfortable with the wattage it produces at 3/4 volume. You may also have speaker wires touching/crossed causing th issue.
Possible problems: 1) No output from the head unit. Try a different set of preamp outs. 2) No input to the amp. Check the RCA's and make sure that they are good and coming from a functioning preamp or subwoofer output on the head unit. 3) Input gain turned off or down too low. 4) Speaker wiring shorted, grounded, or open. Check all wires. 5) Speakers defective. Connect to a known good output to test. 6) The amp itself could be defective and still show a power-on indication.
from your sub connect one short piece of cable from + on one side to - on the other side using the same diameter cable as you are running to the sub from amp . this will leave you with + and - on opposite sides of speaker these will then run to the amp +to+ and - to- on the mono side of connetor which is one left + and one - right and the amp switched to bridged
My recommendation is to get a line level converter. Go to a car audio shop or even best buy and specifically ask for a line level converter. It will have speaker wires in and RCAs out. Connect the speaker wires to the sub woofer speaker wires and then you will have the RCAs to run to your amp. I hope this helped.
you can simply take the input and connect it in parallel to the input of the second amplifier. The output of one amp will go to one speaker, and the output of the other amp will go to the other speaker.
The inputs of amplifiers are "high impedance" so putting more than one in parallel won't put any strain on the radio circuit.
May i suggest removing the equilizer unless you can adjust the settings for each amp seperatly. The amps themselves will allow you to add bass boost and treble boost. I think the problem your having is trying to run to much bass through your system causing it to distort badly.
