Few Stereo Questions for 96 Civic
	
	
		HI everyone,
I am going to install a sound system in the Missus' car as a present and have a few questions that need answering. Normally I would suss the car out myself as I have a fair bit of experience with stereos, but as it is a surprise it is kinda hard to get anytime with the car. 
Firstly the car is a 96 hatch (not real good with Hondas, think that is an EK?? ) and it is an Auto, ok so onto the questions:
1) Where is the best place to run power cable (4 gauge) through the firewall?  
2) What size are the standard door and hatch speakers and what fits easily? (most likely only installing coax speakers) 
3) Has anyone ever done a moulded fibreglass sub enclosure behind the tail light? how much room is there (volume wise) ? 
4) is there room under one of the front seats for a small amp? 
That is all the questions I have for now, thanks in advance for any help :thumbsup:
