Ok so this was another post on my mind for about a year....seeing NOBODY attempted to upgrade the stock sub (actually entire rear deck)...I did it today!
Remove back seat
remove as much rear deck screws and pop rivets as possible - NOTE you cannot remove the entire rear deck unless you remove the cieling carpeting from the trunk (because there are screws under it that go up into deck) - the catch--the carpeting is one time riveted in trunk..
Sooo I just pushed up as far as possible, threw a towel under it and it gave enough room to remove speakers...the rear screw on the sub is a BIT*H!!!!
The 4" speakers I simply unplugged from the harness, cut off the stock speakers and soldered onto the 4" JBL Club 4020's I used for upgrade, then bolted back into OEM bolt holes (there are only 2 bolts in the car that hold the 4" speakers in)
FUN FACT - ALL OEM speakers except for the sub are JBL (sub is only infinity in rear lol)- as we know the OEM AMP is a JBL 500W
The sub on the other hand.....I bought a MB QUART DS1-204 (shallow mount 8") as I had no clue how deep the stock sub is and can now confirm a standard 8" will fix and I will be upgrading in the next month/
There are 2 plastic rings that hold the sub in is a sandwiched configuration, in order to make you aftermarket work you use the bottom plastic plate (bottom slice of the sandwich) and screw your new sub too it, now the stock sub is 4ohm so you just need to uplug stock harness, cut off at speaker on both sides the simply plug into the spring terminal connectors on new sub and mount, plug in and boom!
Sound;
Well the upgraded 4's definitely add the clarity you want, these were never bass speakers, just the mid and uppers to the sub- the JBL 4020's MUCH improve clarity no doubt
The SUB...the MB QUART is more crisp, has a more substantial hit but not the thud the stocker has, this is indeed because it a shallow mount sub and once upgraded to the deep dish that is the stocker it'll definitely out bass the OEM sub (which is you typical crap paper sub BTW).
All around much better sound, all this with stock amp, I'm not looking for crazy bass so for me it's perfect, I just want a clear, crisp, punchy system that makes people smile when not expected in a stock looking system.
I'll take some pics when I upgrade the shallow mount to regular...surprised that rear hole is that DEEP (insert "that's what she said")
Thank guys!,,,,,,,CHAPO OUT!
