I'm still really new to car audio, but I've been catching on to a lot of stuff. However when it comes to what type of box I should get and which subs are better quality I'm still lost.

I listen to a lot of rap, with some harder rock.

I have a KAC-9104d AMP which has 1800 w Max, 900W at 2 ohms, and less than 900w at 4 ohms.

If you could just recommend a hard hitting, good sounding set of 12" subs, that would be much appreciated.

At that power level, 2 RE SE's or 2 Audioq SD2.5s would be nice, depending on what you want. Go with the former for a bit more SQ and the latter for more SPL.

Provided that amp hangs on for you... no offense but kenwood amps are known to be junk. They use very cheap power supplies that eventually fail.

2x on the amp holding on. Also look into ssa dcons, fi x, and incriminator audio 187s. Those are a couple subs that would sound nice and get loud off that power, plus there u.s. Made

You would probably like either of the subs I suggested then, they are both middle of the road models.

cool I'll probably run 2 ohms which is 900 w for my amp, so if that's a 2 ohms sub then sweet

^ that didn't quite make sense.

Your sub may be single or dual 1,1.5,2,3,4,6,8,12 ohm voice coil(s), and they might be able to wire down to 2 ohms. For instance, 2 DVC 2 ohm subs can wire into 2 ohms, it just sounds like you're saying that a 2 ohm sub = 2 ohm into the amp, it's not exactly like that.

If you're getting 2 subs than you want DVC 2 ohm, that will wire into 2 ohms, so yes you were correct... just I don't know how much you know, so... like who knows, maybe you'll change your mind and want 1 sub, and buy the wrong coils. Most subs come in different coils so "if that's a 2 ohms sub then sweet" shouldn't be one of your concearns.

Your amp, most likely, isn't making anywhere near 900W, and I'll bet your electrical is stock? You'll probably only see about 500-750W out of it, which is just fine.

"ssa dcons, fi x, and incriminator audio 187s" - X3?

If the X's are on sale you can't beat those for $60ish, it's just too cheap to pass up.

The AQ SD2.5's are very cheap too, with amazing T/S, I think you get the most bang for your buck here.

I would get the AQ SD2.5's (SDC's?), they have very high sensitivity and the 15" is only $159! Don't they have free shipping? 2 SD2.5's with their 1200D amp would BHHHHANNNNG {oO,}.

Right, if you're amp is 2 ohm stable and you are getting 2 subs you need them to be dual 2 ohm coils.

The kenwood amps are actually CEA rated and will produce rated power, it's just the poor quality that makes them release the magic smoke early.

I do have electrical stock, one thing I plan on upgrading before my new sub.

Thanks for the reply because I don't know a whole lot, i'm slowly catching on.

"with their 1200D amp" that part threw me off.. Get a new amp? (thank you for helping, I know it's not too fun to help noobs)

Yeah he's suggesting picking up an Audioque 1200D as well as 2 12" Audioque SD2.5's. Would be a really nice setup

I see, where is the 1200D better than my KAC-9104d (i'm sure there's plenty of ways but just curious)

more importantly, will my kac-9104d suffice with 2 12 aq sd2.5's

and did you say get svc instead of dvc?

The kenwood will work. The AQ is better in build quality and that it won't go boom after a year or so of heavy use.

Get DVC 2 ohm subs if will be using the kenwood, if you get the AQ you need DVC 1 ohm subs.

hhhmmm why 2 with the kenwood and 1 with the AQ?

and did I read that you can change DVC's from 2 ohm to 1 ohm?

B/c the AQ is 1 ohm stable and makes it's power at 1 ohm, so you need a final 1 ohm load instead of 2.

And NO you can NOT change the impedance of a speaker.


I'm gonna suggest you visit this site and do some reading:
http://www.bcae1.com

Don't worry when you don't understand everything right away. Despite it's name that site is anything but basic.

The Kenwood will be fine because SD2.5's are sensitive, which means they could get louder than 2 12's on more power, 1200w will just give them their full potential, it's real cheap at $249, it's like the cheapest one out.

With Fi you can get parts that allow them to change the impendence later on, but you have to send it to them. You can recone to a bigger/smaller size too, cheaper than buying new.

SD2.5's sound like the way to go, I can get two with my budget, and from what I hear they'll go good with my amp.

I heard a good way for me to go would be to get two 4 ohm subs and wire them at 2 ohms. Will that work with these SD2.5's?

I'm slowly getting through that bcae1.com site, it's extremely helpful (it's finals week next week so it might take a sec to finish it)

Those are DVC subs... 2 coils each... so to repeat what I said before

"Get DVC 2 ohm subs if will be using the kenwood, if you get the AQ you need DVC 1 ohm subs"

cool, I think I'm going to purchase the FI BL 12" 1 for now and a second one later, than maybe in the future (or when my amp goes out) I'll get the AQ and get my BL's impedence changed to match the AQ

Thanks for repeating what you said, my bad..

i dont see why you anticipate your amp going out

as long as you treat it right there should be no reason to think it has a limited lifespan.

That kenwood is stable to 1 ohm, is it not? Read the thread, yall went over this.

Why would he get 2 DVC 2 ohm? unless he wanted to run that amp at .5 ohms, which is prolly do-able, but not reccomended. or @ 2 ohms, which is 2 ohms, not 1.

You could also wire 2 DVC 4 ohm subs into 1 ohm, which is what you want.
1 dvc 4 ohm will will wire to 2 ohms.
1 dvc 2ohm will wire to 1 or 2 ohms.

Not even the whole thread, just the 1st post.

He has 900W @ 2 ohms, which is the lowest impendence he can do.

He wants 2 subs.

Two D2's wire into 2 ohms, and that's what he needs slash wants.

no the lowest is 1 ohm I could be wrong but i think the manual says greater than 900w at 1ohm 900w at 2ohms and 500 at 4ohms. so 1 ohm is what I wanna shoot for from the sounds of it.

Also I will add: You'd be best advised to run that amp at 2 ohms actually. 1 ohm is what kills those kenwoods even tho they claim to be able to handle it, the power supply is not up to the job.

lol thanks, so I should stick with 2 ohms for my kenwood now I found a pair that runs 600w rms each, so is that 1200w rms total? and would 900w rms be alright or too weak

Less than 300W would be weakish, and you won't notice much of a difference between 500 to 1000 watts, it's very miniscule, it's not like turning the volume half way down, it would be like 1-3 notches on the deck.

For 1200W RMS keep your Kenwood at 2 ohms or get an AQ 1200D for $249. You want 2 D1 (or D4) coils for 1 ohm with the AQ 1200 (which is 1 ohm stable). 900 @ 2 is just fine, but try to sell your amp and get the AQ before your amp explodes and you get less when you sell it.

What subs are they?

What vehicle? Did we cover that? I'm too tired to read.

2 Abahn 15's would most likely be louder, maybe not louder than 12" BTL or BL's ETC.

If your friends listen to rap and aren't recommending ported than they havn't had a good enough box to switch over. All of my friends swear by sealed, but their systems suck.

Hockey gear? You'll hardly even fit a hockey bag let alone a sub box and a hockey bag. If you're concearned about a hockey bag fitting than don't buy subs.

You can fit 2 ported 15's. If you want space for hockey stuff than you'll want 2 10's or 1 12 in a slim box.

Keeping 16" depth, you have 4.877 cubes NET/sealed with .75" MDF, which is about enough for 4 cubes NET for 2 12's.

Hopefully you say 16" depth because you know exactly the space you'll need, but the people I know who play hockey can't even fit their bags into the trunks of their cars, their bags are like 40" x 20" x 15", just huge.

I'm hoping you get 2 15's for a ported box and you use the back seat for storage.

thanks exactly the kind of input/advice I like. I currently have a 16d ported box (stupid pre loaded from best buy 2 12" kickers) leaving 16 left and I can barely squeeze my bag in but I do it (subs facing back seat of course) I'm more than willing to use the back seat, just hopin I could work something out with trunk space. but I'm open to all suggestions

Well you said you want a compromise of SQ and loudness so in that case get the RE's.

If the goal were all out SPL the AQs would be best.

I agree, but some ppl want it for competition and whatnot


I used to do SPL comps myself, I had a DD 9515 sub which is geared for SPL but still sounds decent, and a box with two swappable ports to change the tuning.... a 35hz daily port for it to sound decent and a 47hz port for SPL burps. The SPL port gained ~1 db over the daily. That setup did 145s on an american bass 2000w amp.

What's your budget? DD is expensive.

Check out the SSA XCON, used/2005 or less RE XXX (the one with the XBL^2 motor), used could be found for ~$300. No compromises for SQ & output there, the next step up would probably be a RE XXX (new version) or the LMS Ultra at $900 from partsexpress.

I would try 2 12" Fi BL 4" voice coils in 4 cubes with an AQ2200 @ .5-1 ohm, which should be like a 50/50 mix of SQ & SPL.

Thanks, that's basically what I was wondering (how expensive) Couldn't even get an idea.

My budget will be around 400, I'm highly considering getting a great one now, then in the future getting another one identical with an amp to sufficiently power them.

Local pick up, and the best SQ I've ever heard.

The XBL^2 motor retains 70% BL (motor-force) at full xmax when normal designs are at 30% BL, which means lower distortion, better lows, and better SQ. It doesn't have coloring, it sounds neutral and clear on everything.

The box was 2-2.25 cubes @ 36-38 Hz, and it wasn't designed the greatest, no bracing, 1" MDF, I should have done 2.5-3 @ 30 Hz, without rear-fire & port to the side. With my stock electrical and 90A alt it made my Sunfires rear-view fall off 3 times. The car was stolen but luckily the XXX blew a tinsel the week before so I switched it for a $200 Atomic APX.

A Q will come to around $350 with shipping. The Q is like a re-designed XXX, the Q is a lot lighter, but handles less power (XXX is 1600W RMS), and has more distortion. The same guy designed both.

The worst thing is the tinsel being all open, but in my case that's what let me keep it.

Hard to get re-cones, but I'm pretty sure PSI has them and you can go up in size. I might re-cone to an 18" and wall it.
