I know nothing about subs or audio in general but am looking to put some subs in a 1998 honda civic lx. A friend will help me with the install. I listen to 60% hard rock, 40% quasi-dubstep type stuff. I don't use the trunk much so size isn't a huge issue. Headunit is a Pioneer 5200hd.

Budget around $200-220

Does anybody on ebay or the internet have any decent quality kits(subs mounted in box, wiring, amp) for this price range?

Or if not.....can somebody throw some suggestions out for any hot deals they heard of?

If you are willing to do some in depth searching you should be able to find a used BP300.1 or something similar on ebay or possibly here for quite cheap. I've seen them go for less than $80 bucks shipped at times. A single decent 12" sub to run off that amp can go for around $60 BNIB shipped. The remainder you can put towards an okay to use wiring kit & box to fit the sub from sonicelectronix. That's about as good as it gets.

You might be able to go a bit cheaper on the amp by bridging a modest sized used 2 channel amp. Problem with that is efficiency and flexibility won't be that great, but for $200 bucks what else can you ask for?! Check the classifieds here and see what there is to offer...

You might as well go used if your budget is that tight. Better off to get used common brand than new junk brand. I bought some used subs to test amps on and they worked out fine, though speakers are not something I'd commonly buy used. I ran one in the car for a while, fished them off ebay cheap but ebay is not near as busy as it used to be with used. You can scope out pawn shops in your area and try to make a deal, some of them will deal if they want to move stuff. There is one here that sells tons of stuff, a lot of them that don't with high prices. Craigslist is another source, and so on.

This is what I was leaning towards before I saw your link....however looks like that is out of stock.

1. Is a sealed box the way to go in my case?

2. Are dual voice coils worth the extra 10 bux?

3. Would I experience a noticeable drop in performance if I went with 2 12 infinity single coils and a different amp....maybe a Boss Audio R1100M Mosfet Monoblock Power Amplifier with Remote Subwoofer Level Control

The only reason a single or dual VC are need is to get the right power out of an amp.

For example, if an amp puts out 1200watts @1 ohm, 600 @2ohm, or 300 @4ohm. to get a 1 ohm load from 2 subs you would need 2 DVC 4 ohm subs with all coils wired in parallel, or 2 2ohm subs (less common).

If you have 4 ohm coils, 2(coils, not speakers) in parallel is 2 ohms, four coils in parallel is 1 ohm

Read this article on series/parallel. This page has a lot of good beginner info.

Is this the best way to wire them up?
http://i40.tinypic.com/2q8nh1z.jpg

I've never hooked up an amp and sub before. I'll have a friend helping but I'd like to ask you guys if there is anything special I need to do to hook this up? I'm assuming there is a 4 ohm output on the amp and I just hook that up to the speakers?

I've heard some people get engine noise running through there amp....what is best to avoid that?

Yup, that looks great.

As far as alternator noise, just make sure all of your grounding points are free of paint and oxidation. Not only where you connect the amp, but under the hood also.

Thanks Cancerkazoo

So how does it all break down? I'm a complete noob.

Am I giving each sub 250W?
Yes, if the subs are 4 ohm SVC wired like your picture, you will have a 2 ohm load and 500w.

One quick and dirty way of setting your gain correctly involves a easy formula involving the load and watts and setting the amp output to certin voltage while playing a 60hz tone recorded at 0dB.
