Hello

I wanted to now what do you think would sound better 3 12” Subs OR 1 12” & 2 10” Subs all Running at 300W (RMS) @ 4 ohms?

Thanks.

 

If you can drive them, get the 3 12".

 

I don't just want crazy bass I want good sound. Would 3 12" give better sound or just louder harder sound?

 

You don't want crazy bass but you are looking at getting 3 subs?
"Crazy bass" can be provided by 1 sub.

 

I meant that as I want crazy bass & good sound.

 

You probably wants SQL so go for a single 12" sub. 3 12" would double the cone area and will be louder depending on the install. Just stick with 1 12" as mention before.

 

I would go for one of each 10" and 12." 3 is unnecessary unless you have them tuned and set differently. Unless you are going to do audio comps, I wouldn't recommend it. Not to mention you'll lose a lot of trunk space.

 

He'll lose all of his trunk space with three.
I don't think he would notice the difference between having 3 subs and having 2 and having one as far as sound quality is concerned.
EDIT: Forgot to mention the fact that more subs tend to drown out the sound from the speakers... V

 

1 12" is good enough to run. even one 10" which im running. its sound good and not too much of it where you cant hear the music itself.

 

This is the system i was thinking about getting. Trunk space isn't really that big of a deal. Its going to be put in a 99 sedan.

Amplifiers:

In generally I was speaking of range of bass. The 10 could be set differently than the 12 to give a wider range of bass response. It also depends on the enclosure.

Here...

Straight from crutchfield:

"Q: Which hits harder: one 12" sub or two 10" subs?

A: This is a popular question, and one that's difficult to answer definitively. There are so many factors that come in to play — power, enclosure type and size, as well as your specific vehicle and your individual perception. But, generally speaking, given adequate power the two 10" subs will sound a little cleaner and punch harder because their combined cone surface area yields more sound pressure. The single 12" sub, however, may sound a little deeper."

Theoretically, two 10's could hit harder than one 12" but as I hinted at before the rage is different.

 

You make a good point. The range will be different, yes, but noticeable in a car? I doubt it.

 

What kind of music do you listen to most often? Like mostly in the Rock Area, or Mostly Rap / Hip-Hop? If you listen to rock, get the 2 10" but if you listen to rap/hiphop. get the 1 12". Rock is more faster bass so the 10s will move easier and give you a nice loud bass but still not too much. rap will sound great with 10"s too, but better with 12". I listen to all type of music and im running 2 12" subs and with just a little tune from the deck between music, give me the sound i want all around.

 

1-10 JL audio W7 FTW! Its the best of both worlds

 

I listen to everything rap, rock, country, hip-hop, reggaeton anything that sounds good to me or the wife... i think i might go with 3 12" and install a power switch for the amp that powers 2 of the 3 subs so i can power them off when i want only one sub on.

how do you think this would work out? one box big enough for the 3 subs with 2 facing the trunk and one facing the back of the seat.

 

Do you just want a shitload of bass? Because if this is the case then 3 subs is fine. If you actually want to hear your music, one is suitable.
If you face the sub toward the seat, it isn't as "loud".

 

I want a lot of bass but not to where i cant hear the music. My front and back speakers are going to be 75W (RMS) each. Facing the sub towards the back seat wont be as loud? Im guessing the reason it wont be as loud is the space between the seat and the sub? Most of the time I'm going to have the back seat down & even when it is up I'm going to leave room between the sub and the seat. That is also why I say 3 subs once the back is closed its harder to hear the subs.

 

The back seat "absorbs" the waves. If they face the other way, there is less absorbing. I will tell you that I have one 12 in the trunk, and it is enough to drown out the music and rattle my nose hairs.

 

whats your RMS Watts?

 

300.
Have you ever had a sub before? If not, I would suggest just getting one to start. If you want more then get more later.
Usually people only have three or more subs for competition type stuff where loudness is the goal.

 

Yeah, I have a 12" but its fully tuned up just threw it in and left it. It sounds good tho but I don't really hear it the way I would like to. 12" MTX & 600W Kenwood Amp.

Here is the set up I wanted to use:

Amplifiers:
Alpine PDX-5 (75W RMS SPEAKERS & 300 RMS SUB)
Alpine PDX-4.150 (300 RMS SUBS)

Subwoofers:
3x Alpine SWR-1242D

Speakers:
Alpine SPR-17C
Alpine SPR-69C

Head Unit:
Alpine iDA-X305

&

This is the new one I might go with.

Amplifiers:
Alpine PDX-4.150 (300 RMS SUBS)
Alpine PDX-4.100 (100 RMS SPEAKERS)

Subwoofers:
2x Alpine SWR-1242D

Speakers:
Alpine SPR-17C
Alpine SPR-69C

Head Unit:
Alpine iDA-X305

Think the new one would sound better?

 

Your new sub and amp setup is no good.
The subs are 500w rms each. So you need at least a 1000watts rms.
The subs are dual 4 ohm voice coil. Meaning each one can be wired to two ohms or to 8 ohms. This means you need one 500w rms 2 ohm stable channel for each sub, or a 1000w single channel stable at 1 ohm or 4 ohms for two of them.
This kind of power means upgraded alternator, battery, and grounds. It also means you need to run a 0/1 gauge power cable.
It also means you will be spending a **** ton of money.
So what is your budget?
Also: I don't think the new one will sound better. What do you mean by "hear it the way I want to"?
Also what is the make and model of old sub and amp and what kind of box was the sub mounted in?

 

I know I planed on upgrading the Alternator & Battery for this setup cause its a lot of power. Im going to run a 0 gauge power cabal in to a distribution block so i have 2 4 gauge power cabals.

Don't really have a budget. I just want a loud system with strong bass.

Not sure what my current setup is ill have to take a look later.


Ok, Lets say I have a budget of 1500. I’m looking for a all new system head unit, speakers, subs, & amps. I would like to have 2 subs I think 3 is to much and 1 isn’t enough.

 

If you still want an Alpine amp you could look into their 1000w rms amps. You will need to get the dual 2ohm voice coil type Rs. Wire each sub's coils in parallel, bringing each sub down to 1 ohm and then wire the 2 subs in series, bringing it to 2ohms, which is what the Alpine amps are 1000w rms into 2ohms.
You are looking at a price range of $300 to $500 if you buy online for either of the 1000wattrms alpine amps.

 

It doesn’t have to be alpine but I just like there PDX line of amps there small and powerful. I hear a lot of good stuff from there R series of subs and speakers that why i went with the all alpine system & I like the head unit cause its all digital. I would rather use USBs or iPod/iPhone for music so I don't have all the CDs around the car.
