so i have a alpine amp that is rated at 300 watts rms @ 4 ohms and 500 watts rms @ 2 ohms. is the 500 watts at 2 ohms louder and more punchy than the 300 @ 4 ohms? or are the roughly the same? and how much louder is a 12" than a 10"?

 

im not a a/v guy but ohms is basically resistance your 12 volt system has. your amp has less resistence and more power at 2 ohms, hence the higher wattage, so you have more power to use for your sub from your amp. if im wrong im sorry, im jsut going with what i think is right. aand it depends on the brand and size and model and all that. it helps if you hear them play before you buy obviously.

 

In your case I would recommend getting a 12" 2 ohm sub thats 500w rms.

 

k i have one in mind...

 

a good 10 can be just as loud as a 12...especially if ur only looking at 500rms...its when u start getting to like 1000+ that u need to worry about it...i think?..i take it ur looking at a new box to? are u gonna remove a jump seat?

 

yea i kinda want to take out the jumpseat behind the drivers seat and make a custom box to fit there....(tim ima need ur help on this one! haha! i wanna talk 2 u bout if u can make boxes nd how cheap it will be. hit my celly up cuz i dont have ur # anymore)

 

Im not sure but i think that there is a little bit more to it then just pulling more watts from the amp...

I can't remember, but i think its recommended you run a dual voice coil 4ohm sub wired in parallel (2 ohm) would be best if you are trying to run at 500w. and a single coil 4ohm if your going to only pull the 300w.

You may want to look into it before you buy. jfyi
i may have read that on crutchfield.com not sure...

 

That is correct if you want to get the amp down to a 2ohm load you will need a DVC 4ohm sub wired in parallel or a SVC 2ohm sub. Yes it will be louder at 2 ohms but make sure your sub will handle 500rms.

.

 

yea i have an idea on a JL sub thats 500 watts @ 2 ohms

 

not sure if this thread is dead or not but i have JL 10W6v2 and it pounds harder and louder than any multiple sub system using 12's i've ever had. i have it in my F150 now but when it was in my ranger it was borderline rediculous. this being said, go for quality not quantity.

 

yea i can see that cuz u have a high end JL. i think i just need to broaden my price range a bit and just know i will get a good sub for more $$$$!

 

just go with 2 alpine type rs at 2ohms :) like i have

 

+1 for the JL subs! I have a 10w6v3 (IIRC) in my mustang and it's just silly.

If you stop by local stereo shops and look around online, you can usually end up finding a killer deal on them. Like NIB last year model closeouts, etc...

 

For the 10 vs 12, it really depends on the style of music you listen to. 10's "can" hit faster than 12's, better for rock styles. Were as 12's can hit lower notes (depending on the tuning of the box) better suited for rap and what not. Many different factors in which will be louder.
