[QUOTE="kottke, post: 3103658, member: 577976"] Alright, it seems as if things are beginning to sound a bit better. I tried changing the phase of the woofer and checked everything else. I don't think anything is/was out of phase. I decided to start from scratch and re-evaluate all my components. First of all, I used a digital multimeter to set the gain on my amp. The amp pushes 480 watts x 1 at 4 ohms. The ID 10 is dual 2 ohm vc wired in series. I set the gain to put out 34.6 volts which of course translates to 300 watts RMS. On the image dynamics website, the recommended wattage range is listed 50 - 400, so 300 RMS isn't too much power is it? Before I had tried to do it by ear, but I just wanted to make sure I wasn't pushing too much. Secondly, I moved the sub out of its usual position behind the seat facing toward the rear of the trunk. Instead, I put it in the rear passenger's side corner, facing outward. An odd spot, I know, but it seems to have increased the bass while also not sounding quite as localized. So, things sound a bit better now. The only thing that is still bugging me now (because I'm a picky S.O.B.) is that when I'm sitting in the driver's seat, if I lean forward about a foot, putting my face just above the steering wheel, the whole setup sounds awesome! The bass is even better, the front speakers sound much more balanced, all in all, it sounds exactly how I want it to sound. BUT, when I lean back into my normal driving position, it goes back to sounding just a bit "off." Not as bad as before, but I can tell a difference. I have a 2006 Honda Civic sedan and the **** thing has a veerrry deep dashboard. Could that be why it sounds better leaning up some? I know this all sounds all probably sounds pretty stupid, but I really appreciate you all trying to help. Thanks. [/QUOTE]
