8th Generation Honda Civic Forum - View Single Post - DIY: Installing Aftermarket Subs w/ Stock HU ( and Premium Sound System)

Hey guys,

I vaugely remember seeing a "Subwoofer" level control in the manual for the stock HU (The section where you adjust the Treble, Bass, Fader etc). Is there such a thing? And if so, is there a possible way of controlling the subwoofer output on an aftermarket sub+sub amp? When i got my civic it only came with the stock HU and the 4 speakers, no subwoofer, but I have a PPI 2400 amp and a rockford 10inch sub which I would like to install. Having read some of the posts I know that I will have to run a power wire (+) from the batter, and another wire for the ACC signal to the PPI amp, and connect the ground to a metal point of the body in the trunk, but I would really like to be able to use the stock HU's subwoofer output control function. Any input would be appreciated. Also, where is the stock amp located? Also I noticed on one of the posts that the stock amp has 2 outputs for the subwoofer:

Subwoofer 1 + Green
Subwoofer 1 - Red

Are these amplified outputs or preouts? How much wattage and impedance do these connectors handle? Do these have to have a load accross them to get the Subwoofer level control to show up on the HU audio adjustment? Is it possible to connect a LOC to these outputs rather than the rear speaker outputs?

Thanks for your help.
