I know this has been hashed over and I read through the threads I could find, but could not find an actual wiring diagram of the B&O system. I'm curious about the line running to the sub in the rear deck, is it a true sub out from the amp? Could I theoretically run the line in the rear deck into a small aftermarket amp and then to an aftermarket sub I put in the stock position and not worry about filtering the signal? I want more bass range, specifically lower, and more power to it. I have the bass pretty much cranked to 11 and it's really distorting the rest of the system. I think if I can dial that back and turn up the gain a bit on a better sub in the back, it would really round out well. But trying to do as simple an install as possible.
'11 with B&O
John, what your progress was on the sub install? Did you get the custom free-air woofer you were considering?
Got it. I just checked the spec sheet and on that JL, there is a small switch that can toggle from low-voltage to high-voltage on the RCA inputs. So yes, it makes sense now that it's tapped directly off the B&O subwoofer outputs directly into the JL inputs. Very nice setup. I might have to flatter you and do the same on mine.
I'm not comfortable doing this install on my own, so I got a couple of quotes from some local stereo shops. One mentioned that the mentioned sub is not meant for open-air, and recommended the JL ZR series. Does anyone have any info on the ZR? They said it would be able to play lower frequencies than the 10W1 and wouldn't hang as low in the trunk/shelf.
That would require something like the mOBridge Digital Pre-Amp m1000-m-da1:
I couldn't tell you with absolute certainty since I didn't do the install, but it was explained to me that rca's were tapped right at R157 on the diagram. The amp itself has a filter, so it's ran straight from the tap to the inputs. I can get the specifics for you if you need.
I'll ask when I take the car in again next week. They had hot glued a support bracket behind the carpet to handle additional weight of the box, but it seems to have broken and the box has not been clipping in securely. I've hit hard right turns and twice the box popped out into the trunk. They're going to fab another support and screw it in behind the carpet this time, and we might put a snap in the pull tab that holds it to the top.
I'm in Missoula, MT, 406 Motoring did the install for me.
anyone have any suggestions on the best 10 inch free air sub to run off of a 500w amp?
