I have an MTX RT2200X 60amp amplifier( 425 watts) and one subwoofer, MTX T8124(400 watts rms) 1000 watts peak). I originally had this installed in my '94 honda civic. Now I want it in my 94 accord. The only difference between the installation now and my previou installation is that the last head unit I had didn't have RCA out, so it was hooked up via hi input to the rear speakers, my civic was DX, came standard with only 2 front speakers. So the rear speaker wires were hooked up to the hi inputs in the amp.
My current setup has the same amp, and sub, but I'm using RCA cables now. I have a sony head unit, the old models, but it has rear/front out RCA outputs. I have the power running down the right side of my car, in between the battery and amp I have a 60 amp fuse, and the power is hooked up to the [batt+] of the amp. The [ground] part I screwed a wire into the chassis of my trunk. The output from the amp, it's 2 channel, I have it bridged, from the 1st channel: left (+), and 2nd channel: right (-). Those went out to my sub. I have my RCA signal cables running down the left side of my car and into the amp. There's also [remote+] but I have nothing hooked up to it. There's already power going through. The crossover button is off.
When I start my car, and turn on the radio, the power of the amp is on, but I hear no sound. It's as if no signal is going through. I'm not sure if the problem is between the head unit, that no signal is coming out, or from the amplifier to the sub, as in it's not transmitting any sound to the sub. I don't know what's wrong. This is my first installation, I don't want to pay $50 for someone to install it.. I hope someone can help me. Thank you.
