Sub Stage in 98 Civic Coupe

[IBmikexxx 10+ year member]

Ok, so I'm trying to decide which sub to run in my coupe. I want something thats going to move, but also fit within my electrical capabilities. I have a 90 amp alt, I'm going to run the big 3, and I can always run an extra battery I have laying around, but thats the foundation of it. I have a pair of ID 6.5's up front that will be fed 125 watts to each side, and so now I need to lay the sub stage. I think I'm pretty set on it being a ported 12 tuned to 33 hz, however nothing is etched in stone. Its going to be a daily set up, and I need to figure out what 12 would fit my layout best, as well as some things I'm currently researching (ie. sub firing direction? port side? I'm not sure how those influence the sound). School me if you could, and let me know what your opinions are on some quality 12's. Much appreciated.

if you not stuck on 12s you could always go with a pair of sa-8s in 1-1.5ft^3 tuned to 30-33. and put it on 1k.

Na, nothing is etched in stone. I'm watching video's and reading about them now. Super impressive sub for sure.

How do I approach the sub and port direction?

well, ideally...i would fire into the cabin. But that would require "baffling" off the trunk from the cabin. This would most likely produce the best results if you can do it.

I don't think I'll be able to do that because of the back seats. I want those still

in that case run subs back port back, or port side, depending on how much space is between the side of the box and the walls of the car

i say subs and port back....

ive seen quite a few trunk cars get quite loud port side, but its also down to preference

Yeah I feel like thats pretty standard. I'd probably end up with little space on the sides of the box. Not sure what the sa-8's require for size.

an sa-8 only needs .5-.75ft^3 for ported. so get 1 cube after displacement and you should be golden, find out what the max dims you have to work with are and look up ram_designs on here, he can hook you up with a very nice box design if you send him a little paypal gift, ami creations can also build the box if you dont have time or the ability to. he does awesome work.

Pairs of SA8's on 1kw are seemingly always impressive for the amount of space they take up. If you want to stick with a single 12, the Mach 5 IXL works well in smaller boxes and can handle a good 600-800 watts. 1.5-1.75ft^3 at 30hz is all you need for the 12"er.

I'm really kind of feelin the sa-8's. There's a ton of rave about them, and they're seem impressive, no doubt. Not to mention, with me drivin a civic, I'm sure i can get the box sittin good in the trunk. What do you guys think I should run to push them.

you could always go with one of the many 1500 watt amps that are on the market, from ap to mb quart to the saz and just tone it down, that way you can upgrade subs in the future to something more powerful and have some extra wattage to play with.
