I am really pondering getting this put into the GS300 within a few weeks. What is going to swap out is camera choice and how I do the sub. It has been recommended that I make a enclosure in the rear that covers the sub. Anyways, I don't care for navi or bt as I originally wanted as I have both as external units and hate talking on the phone and I am okay with my navi unit. Plus I can always add that later.

Head Unit - Pioneer AVHP-4200DVD it lacks the bluetooth I really wanted, but then again I gain a 7inch screen over the one I was looking at. Navi isn't something I need right now either as I have a separate navi already.



Speakers - Polk Audio db651S w/separate tweeters



Rear facing camera - This one will most likely be a lot cleaner to this Pioneer shown.



As for the BASS!! the car comes with a 10inch OEM sub that needs to be replaced as it doesn't give enough Ooomph that I am looking for in a clean manner. I'd rather not have to go with a enclosure for now. I am hoping he can figure out a free air system and I'll have to power it, but that'll be later on.

 

Im getting the same head unit for my GS. Pioneer sells a blue-tooth add on if you still want it. Im adding ipod, hd and sat radio to mine. For sound i believe in doing it right the first time, I get great discounts through work so im using dynamat on the whole car, 2 alpine type x subs, 2 alpine 1000 watt amps, 2 sets of kicker QS 65.2 components (I couldn't pass up the excellent price I get these for). and 2 Alpine 300 watt amps. Im going for sound quality here.

 

In my old GS I used a Kicker free air sub in the rear deck. It sounded ok, but got annoying at high volumes because it rattled a lot. In my GS now, I removed the factory sub and had a custom enclosure built for 2 10" subs. It sounds a lot better with less rattle.

 

I should note I will be adding sound deadening to this setup. I do not listen to music so loud anymore. What I do prefer is clean strong bass which doesn't require the volumes to be "mind blasting" and I should still feel it, but hold a conversation. I'll have to go with a enclosure setup.

I doubt I will add BT to the unit as it cost way to much and Navi would be the only option. If I wanted both, then I'd just get the original H/U I want which already had both built in. I'd rather have a rear facing camera over bluetooth.

 

I look forward to your solution for switching out that oem sub because ive had the same idea for a while and have yet to take the time to figure it out hah
