current setup
car: 2003 sunfire
hu: alpine CDE-103BT
door speakers: 4.5 inch alpine type s
rears: 6x9 inch alpine type s
amp: sony 4 channel 70w rms/channel running all 4 speakers
subs: 2 sony 10inch svc (*not installed yet)

question: Does it make sense to add 6.5 inch speakers to my rear doors? Would it be overly difficult to install them? Any suggestions on which ones to get if I do get some? If i put 6.5's in my rear doors should I return the 2 subs I have and go with one 10 or 12 inch instead, any suggestions on a good single sub to get?. And finally, what's the best way to go about powering all of this, I was thinking: rear doors and rears to current 4 channel amp, front doors to hu and sub to separate monoblock. A lot of questions in one post, even a little advice is appreciated. Thanks!

 

keep the 4 channel for the fronts and you can add speakers to the rear doors

if you took the Sony subs back I could give you a package deal on a SSA sub
and a nice little monoblock amp to run it...

 

alright, so keep the fronts and rears going to the 4-channel, what should i run the rear doors to? and what kind of deal did you have in mind cause i payed a grand total of 60$ for the two subs and have been looking in to the kenwood kac 8014 mono (120$ shipped) from ebay to power them, so if you can compete with that, that would be cool.

 

I can not compete with $60 for a pair of subs and $120 shipped for an amp
that's less than my dealer cost

 

my local electronics store were basically giving those subs away haha, and it's actually 130$ shipped sorry, and i'm only looking at getting one sub if that makes any difference.
