What an improvement! I turned mine all the way up and then just adjusted the bass on the headunit until I found the sound I was looking for.
The amp is mounted sideways next the battery.I can find the amp, I can't find the knob...
Dito, I just did this mod this afternoon (wish I would of done it last spring so I could of had nice music all summer) and as I rotated the know back and forth a couple of times to hear the difference, I went into the head unit, put on some hip hop, adjusted bass/treb/fade and then went back and adjusted the knob. Got it to about 100% and then the sob fell out of the amp. Tried putting it back in place, fell out of my fingers into wheel well beneath the amp and now I can't find it. Luckily, I had it turned up so I'm just going to leave it.Just did this as my first DIY mod - works as advertised. Just be careful with the knob, mine came loose as I was adjusting it and dropped into the battery compartment. Fortunately it couldn't drop too far and I was able to find it without taking everything apart.
I'm pretty sure this is it(circled in red), I had my trunk apart this afternoon screwing around and figured I could get a picture. Point of view is from the front looking to the back and towards the battery.Can someone please post a pic of this "knob"? Maybe I'm trying to turn the wrong thing?
