Hi All, I'm looking at buying an 2009 2.5X Forester.

The current setup i have in an Impala (which I'll be taking with me after trade) is:
Pioneer MEH-4100UB (love this unit - Full Ipod interface thru USB + Charging)
with this unit you could interface it with an adapter to the steering wheel controls or just use the Pioneer remote that comes with it.
Infinity Kappas 5 1/4's (adapter will be required to fit them into the 6 1/2 Forester openings I think)
Infinity Kappas 6 x 9's (these may become paper weights)
MB Quart DSC4800 4 Channel Amplifier (about 160 true watts per channel makes your ears bleed)
No Sub yet...

The questions I'm looking for help on are;
-If I got the Pillar Tweeters from Subaru (an easy install I see) are they run as a seperate channel or are they wired as component tweeters of the front? The wiring is pre installed at factory
-What are the Ohm/Watt/Freq Response ratings for these Tweets?
-If I used the steering wheel control adapter (Pac-Swi adapter), can you configure the < and > buttons to skip songs on an Ipod?
-If the Amp is 14.17"L x 9.45"W x 2.7"H according to the spec sheet, will this fit under one of the seats?
- Which seats will it fit under?
-Do I need a special Double Din Bracket to make this head unit fit?
-Any thoughts on makin the 6 x 9's work somewhere on the vehicle?

I'm sure there will be more questions to come, thanks in advance for any help recieved!

 

Correction, after digging out the factory parts in the speaker boxes I realised the front Kappas were 6.5" so no adapters needed there now!
