[QUOTE="LDR20, post: 8666413, member: 676365"] Hello, I am new to car audio. I tried to read up and watch as many videos as I could to make the process smooth but now I'm stuck. I have all brand new equipment. I wired everything up and got it all into place and when I turn on my music, the subs work but are extremely quiet. If I am sitting in the car I cannot even tell that they are on. When I look at them they are not moving visibly. The only reason I know they are moving is because I can feel them. This is what I have: - 2 Power Acoustik MOFO-122X Dual 2-Ohm Voice Coil (1,350 RMS Each) - 1 Rockville dB15 6000 Watt/3000w RMS Mono Class D 2 Ohm Amplifier Car Audio Amp - 1 Metra - Two Channel Line Output Converter - 1 ASC Dual 12" Subwoofer Universal Slot Vented Port Sub Box Speaker Enclosure My car is a 2013 Kia Optima with the Infinity sound system upgrade. From my understanding, the car uses SPDIF from the head unit to the factory amp. This means I had to tap into the speaker wires coming out of the factory amp. I wired the speakers to keep them 2-Ohms. I'll include a diagram of how I wired them. The only knobs I have messed with are the remote volume on the new amp, the knobs on the LOC, and I very slightly turned up the gain knob on the new amp but was too scared to turn it up any farther because I didn't want to damage anything (I ended up turning it back down right after). Any suggestions? Your help is greatly appreciated. [ATTACH]3883._xfImport[/ATTACH] [/QUOTE]
