i'm planning to the get the pioneer avic d3 for my 03' gs300. 1 of the many few reasons: need an upgrade in stereo, navi, dvd player etc...
question is if i replace it, is there any way of making the stock sub (planning to replace that as well same size) work? will i need a new amp or what not??? thanks guys...

 

you should be able to use it by bypassing the stock amp. but i'd run a newer amp.

 

get a new amp & sub

 

i got the d3 and running a 10" JL sub with a Fosgate amp..forgot what kind since i got it as a gift. still using the stock speakers and they sound fine. although my rear left speaker just blew.

 

you would be better off running amps one for your sub and another for your highs also there is a bypass so you can use your navigation while driving and watch movies although you shouldn't do that lol and i also would take the sub out and run a box free air sub just don't sound that good i wouldn't even waste my money jl subs i think are the best bang for your buck i still have wo subs from 10 years ago running in my home towers after taking them out of my old truck and fosgate amps are great for bass and i like my new pioneer premier amp for highs

 

i have a d3. instructions in the DIY sticky of this forum shows you how to bypass the factory amp and keep your factory sub, the problem with this is that it makes it 2 ohms. my friend had done this to his car and had ended up blowing his factory amp. whereas, i bypassed mine without keeping the factory sub. i'm currently running a avic-d3, and 10w7 in a sealed enclosure in the trunk. my suggestion, go the old fashioned way and go with a aftermarket sub and amp.

 

ok thanks for the info guys...

ok, now i'm also looking for a TTE lip plus a L-Tuned Grill. can you point me to the right direction on where i can get both at? i tried L-Tuned.com or something like that but they dont seem to have it.
???

 

Idk about the grill but there is a group buy that's going until next friday right HERE
