I've been looking at the DC lvl 3 12'' subs but I'm not sure what I should get, I'm a complete noob to this stuff.

I'm going to power the sub(s) with either a sundown SAZ-1500 or SAE-1200

Going in the trunk of my 02 mazda protege sedan.

I like to listen to a lot of metal and rock music. I've heard sealed boxes are better for fast double bass, but I've also heard that a good ported box can handle double bass as well. Others say the bass will blend together in a ported box... what do you guys think?

is the dc lvl 3 the best sub for my money?

Good choice on the subs!

I run Incriminator Lethal Injection subs and love them.

There are so many choices, you cannot make a bad choice if you stick with what is sold in the SSA Store.

nice amps, i would go with the 1500d just so you have room to work with.

What kind of budget are we looking at?

Check out AudioQue hdc3 or the Sdc series. Best bang for buck in all honesty!

I think you'll want sealed. Maybe a couple Fi SSDs or IA Lethal injections.

What kind of budget are we looking at?

I'd like to spend about $300 on the sub(s), is it OK to buy used subs? or is that a 'no-no'. if they "seem" to play well and look like they're in good condition?

or would I be better off just buying them new?

So you guys think

AudioQue hdc3 or the Sdc series,

Fi SSDs or IA Lethal injections

Are better options than DC subs?

I like this idea, if you are set on 2 12's. Did you consider a single 15?

I'm open to any suggestions. Remember I have a small sized sedan though.

I've never heard a real system before, and the best audio shop near me is radio shack

I know sq is sound quality and spl is loudness, but what is the real difference? Yeah sq produces the notes more accurately and the frequencies are flatter. But what does that mean in respects to listening to music? IDK which I'm looking for... I'm not going to be in any competitions or anything like that, I just want to feel the bass resonate inside my chest.

To get that, what do I need? Should I have a ported enclosure or vented or sealed or ???

I'd like to be able to at least fit the sub(s) and 2 amps (cabin & sub amps) in the trunk. and at most some storage/air space.

Ha I drew these, are things like this possible?

Most of the time you'll want the port and sub on the same face of the box. Generally, putting them 180 degrees from each other is the worst thing to do. Not to mention that the port will have depth to it, which might run into the motor in the boxes you drew up.

If you want the kick drum in rock to sound the best, generally your best bet is sealed.

A ported box will exaggerate the 30-45 hz range, and to some that sounds boomy or too exaggerated. But also to some that is exactly what they like.

Alright thanks! I thought the ports were supposed to be on the opposite side for some reason...

Is it better to have the port running into the cabin right? I was thinking of putting a hole in my rear seat to show the port through. Or is that stupid?

When the subs are in the trunk, should the port/subwoofers face toward the front of the car, or toward the rear? (trunk = rear, engine = front)

Most have the woofer(s) and port facing back towards trunk opening with good results.

I don't necessarily want my ears to hurt, but I defiantly want to feel the bass in my chest. a LOT of bass in my chest! Does that mean I want SQ?

Here are the dimensions of my trunk:

Would I have enough room for a ported box?

It is not always better to have the subs and ports firing into the cabin. If you face them backwards you get a loading factor, much like putting your home theater sub in a corner. The sound waves really only have one direction to travel, and that's bouncing off of the back of the trunk and into the cabin. If you face the subs forward without sealing off the trunk, you'll have some waves that want to go backwards, back into the trunk, and cause cancellation and things. Your absolute best bet would probably be to face them forward and seal off the trunk behind the front baffle. However this takes some work that some people don't want to do. If you just want a drop-in install that will work just fine, fire both port and subs backwards and rest the box so it's about 6-10" from the back of the trunk.

Are you meaning like physically cut a hole into your back seats? I wouldn't do that. People usually have good results cutting extra holes in the back deck though, to allow more sound through.

You may have to build both a sealed and ported box to decide which you prefer. Don't worry about using the term SQ.

Alright thanks, I think I'll just port them toward the opening of the trunk towards the rear.

I want to feel the vibrations without it pounding on my ears. When I say feel the vibrations, I want a LOT of vibrations resonating inside me.

I have 2 12'' cvr kickers right now, running off of a 1200d SAE sundown amp and when I turn the volume up, i can't feel the vibrations as much as I would like, but at the same time I can feel a lot of pressure which I DONT like.

What subs do you think I should get?

And is it OK to buy used subs? or would I be better off getting them new?
