1) Where is the amp located?
2) What size (and maximum depth) are the speakers in the front, rear, and tweeters?
3) What are the watts (RMS) for the speakers?
4) What size is the Subwoofer?
5) How many watts (RMS) is the subwoofer amp?
6) Does the subwoofer have a separate amp apart from the main amplifier?
7) What are the dimensions of the amplifier?
8) What brand is the Head Unit and amp?

Thanks in advance for any help that can be offered. I'm trying to get ideas as to how I'll upgrade the audio...

 

1. took apart dash and only saw a basic head unit there - not sure about a seperate amp
2. 6.5" standards for the doors and rear - no idea on tweeters - the doors hold pretty deep sepeakers (alpine components went in fine) - for the rear deck you will either want shallow mounts and a 1/2" riser or regular mount speakers and then have to remove a bit of the trunk tension rods (it isn't as bad as it sounds - or wasn't for me)
3. they are basic single cone ddrivers and don't list the watts... frankly if you want a good system you will ditch them.
4. 8" but doesn't sound too bad considering
5. It says the system is 360 peak power - I am guesing 50/channel peak for the mains which matches most aftermarket head units, the rest to the woofer?
6. already answered
7/ see above
8. I was told Alpine and it seems to fit with their sytling and the way their systems work, but it doesnt say that anywhere on any literature.
