I'm considering installing the Pioneer AVIC-X930BT navigation unit in my 2001 GS300. I've read just about every topic on CL and from what I gather, it's necessary to bypass the factory amp. Doing so generally renders the subwoofer useless unless you buy a aftermarket amp.

Here's my question. Since I'm really only interested in the navigation capability and want to keep all of the factory speakers without upgrading them. Is it feasible to just feed the subwoofer out from the header unit directly into the factory subwoofer without an amp? Adding a mono amp for the sub significantly increases the amount of wiring. Is a pioneer device, or any device for that matter, able to drive the factory subwoofer?

The double din nav unit has "MOSFET 50 Watts x 4" but I'm not sure if the sub out is bumped up or not.

EDIT: On that note, are there any good guides to how to install an amp and wiring? All of the guides I've found are incomplete because the images are down.

I just installed a Pioneer double din in my GS3 and I wired the factory sub up to the drivers rear speaker. Sounds better than stock but if you really want some bass then you will need to get a new sub and amp.

Excuse my dumb questions as I'm a complete nub when it comes to car audio systems.

The HU has up to 50W per speaker and you spliced the rear speakers to power the sub? If so, did you just pick RL or RR speaker to power the sub?

Is there any way to have a mix of left and right to come out of the sub ?

if you want to keep everything stock then just buy a portable navi. unit

I followed this diy. More info about hooking up the sub to the rear speaker in this thread.

You say it sounds better than stock, you mean it sounds better than it would have been had you left the Subwoofer unwired?

I don't usually turn up my music that loud but I can appreciate the lows. I'm satisfied with the current factory speakers as they are. Is wiring the subwoofer to the driver rear very similar to the factory setup?

The speakers sound clearer to me since installing the new head unit and the bass is about the same if not slightly better than stock. Keep in mind the stock pioneer setup doesn't have much bass anyway so don't expect much more than stock.
