Is this Setup to much?

[aceorama1 10+ year member]

I am looking to install Alpine Type R subs into a BMW 1 series. It is a small sport coupe and I have been leaning towards the idea of running dual 4ohm Alpine Type R's at 1ohm at about 700 watts each. I need to know if this is going to be "to much" for the car I'm driving.... would it be better to maybe just have a single Type R?... In other words I don't want to damage anything.

you probably won't be able to fit the box for 2 type R's in that car. better to do a single 12 in a nice big enclosure than stuff 2 into a tiny box.

1 12" type R ported with about 700rms would be nice i think. I only have 300rms going to my 12" and its plenty IMO

i could fit a box. I alrdy measured and i can do a box probably just over 4.o cubic feet

I agree.

A single Dual 2 would be good for a single subwoofer application, then you have two common choices for impedence, 1 or 4 ohm.

I have put two 15's in sealed boxes before into a tiny trunk, and it sucked. I wanted to go ported, but space is limited in my ride.

A single D2 15" might be a good option too, if you have room to port it.

huh. i stand corrected. if you could fit 2 cubes per sub, then it would work fine. total box volume with port and sub displacement will be larger than that though.. 2 cubes is just internal volume not counting port and sub. or thickness of the wood.

gotta be careful there too. a kicker L7 15 likes 6 cubes. a focal 16 does well in under 3 cubes. it varies.

well assuming i could do something like 4.5 cubic feet would 2 12's be overkill? i honestly dont want to ****up my car

it won't damage it too much. most people wouldn't be listening to 2 type r 12's at full tilt anyway in the right box very often. but, most people haven't heard them in a good 4 cubes tuned to 35hz. almost any 12 is impressive to someone who's only had prefab boxes. it's subjective. no way to tell if it'll be too much for you.

Well, if it were a type R 15", then it would be a good sub for filling that small trunk.

type R performs well in 5 cubes. still works pretty good in 4 cubes though, so you're probably right.

my type r's ****, i wish i could feed them 300 rms and be happy.

Humm, 2 type R's in a BMW seems like a waste of money. 1 properly powered should more than do the job! There again, it all depends on what the drivers wants. I use to run type R, trust me 1 will get it done.
