The next thing I want to do to my car is install some backspeakers and a sub (or two). When I installed new front ones, I was planning on getting an amp put in ahead of time, but they said i needed more power, cause my battery probably couldn't handle it. Anyway, I am driving a 91 Civic Sedan DX, and was curious as to where you guys think I should put the speakers/sub.

Heres my ideas.
2 speakers on the mat above the backseats under the window
either 1 medium sized sub under the backseat, or two smaller ones under the back seat. (does anyone know if you can even do this with this car? I drove in my friends mustang and she had subs under her back seats, thought it was a neat concept.) then put the amp behind the backseats of course.

What do you guys think?

 

i have 2 Boston Acoustic 12's in my crx with a fosgate 400 amp sounds real good and i still have the stock 4 speakers that the car came with. but 2 10 will sound good also...the key to a good sound system is a good head unit and the box that the subs are going in.. if the subs have huge magnets you will need a bigger box then the smaller magnets... do research and you will have a good system...

 

box size depends on what you want your tune to be, not how big the magnet is. the bigger the box the lower the note. as for putting them under your back seat, probebly not with out some mods..

 

Front door speakers are 6.5", so are the rear deck. Replace all 4, get 2 10" subs and a 600watt (approx) monoblock amp for the subs and you'll be more than happy. You dont really NEED an amp for the speakers, just wire them to the deck. Also, you may want to get a 1.0-2.0 Farad cap.

 

i ran a 4 chanel amp fosgate 800.4 in my rex..chanel 1 ran the front and rear 6.5 on the driver side of the car chanel 2 ran the passanger... chanels 3+4 were briged mono to my 15" soundstream spl 150... chanels 1+2 were on the high pass filter on the amp and chanels 3+4 were on the low pass ...also had a 2.0 fared cap..

 

I have one 10'' jl w6's in my eg with an audiobahn monoblock amp and the rest is with the stock head unit and so far it is better than i expected

 

well since everyone is all ooo this is what i got in my trunk, my turn. i have 2 digital design 9512's dual 2 ohms. 2 kicker zx2500.1's wired to 1 ohm. 2 sets of kicker rs 6.5's no amp for them yet but soon, there ran off of a alpine 9811 head unit. umm a 7 inch monkey video screen with a half din dvd player. as for power i have two kinetik hc2400's one under the hood and one behind my passenger seat with 4 runs of zero guage going from my hood to the battery in the back.

as for caps there useless they hurt your voltage more then anything.
