Most car audio devices (like head units and amps) require a REM (remote) line to be connected to a switched power connection. This switched power is on when the car key is set to ON or Accessories.
Not knowing what Sony unit you had, I can't be sure, but it is likely your Sony had higher voltage preamp outputs than the Kenwood, as the KDC315 has 2V outputs.
If your Sony receiver has a separate sub output, it probably has a fixed level for application to a powered sub. Your mono amp can only boost the fixed signal level it receives from your receiver. The receiver can't drive that mono amp harder
make sure all your wires you are using to connect the amp are 4 gauge check your ground make sure its drilled threw thick metal scuff off the paint that its grounded too and check how you have your subs wired see what ohm there wired in the you can get more power out the amp in 2 ohm then 4 ohm
I guess this Amp is stable down to 2 ohms. 500 Watts X 1. Unfortunately there is no way possible for you to present a 2 ohm load to the output of this amplifier. Here are your options.
Speakers in series with VC in parallel = 4 ohm total Z Speakers in parallel with VC in parallel = 1 ohm total Z (not good) Speakers in parallel with VC in series = 4 ohm total Z ( Whats the point) Speakers in series with VC in series = 16 ohm total Z ( Whats the Point)
So your best option to maximize power transfer from your amp to your speakers would be option 1. (Z = Impedance)
the trick is not to use you deck to control the bass. use the amplifier and set all you radio setting to 0 this will allow you to fine tune a little audio when you need to, make all your bass tuning setting at the amp. not the deck,
Check your RCA's from the amp to the deck, make sure it's on an output not an input on an aftermarket deck,and the input, not the pass thru on the amp. If you have it hooked up to a factory deck, you've opened a whole new can of worms! If its a factory Deck; Post the make and model of the unit if you can find it, as well as the vehicle year make and model. I get as much info as I can on it and walk you thru the details. If it's aftermarket and you've checked the above, post the make and model of the deck and I'll do the same. Hope this helps
Double check all of your connections. I know this same problem has happened to me and come to find our that all the problem was the fuse blew that is connected between the radio and amp. Also check you battery connection. Corrosion on the power cable will also cause it to have a bad connection.
