Hi all!

I have a 2005 Base coupe (no premium sound system), and recently upgraded the head unit to an Alpine CDE-121, and love it so far.
Except for one big problem:
The head unit is stuck in the console. Apparently the radio removal keys for the CDE-121 go along the outside edges of the stereo, and there isn't enough room to slide the keys in. Obviously I don't need to be taking it in/out every day, but within the next couple of weeks I will need to access the rear of the unit to wire up an Infinity Basslink- is there a way to access this WITHOUT removing the headunit? Any other suggestions

Which brings me to my next questions:

I like the sound of my new head unit, but thought about getting the Alpine KTP-445 Power Pack, which would increase my output by 4 x 45 Watts RMS - Is this worth getting with the base stock speakers? Will they be able to handle this, or will I need new components too?

Thanks!
