What size sub?

[cheese20323]

If you do end up upgrading to a sub I reccomend you put dynamat or whatever on the rear deck it is what rattles most..I have 2 12's and have virtually no rattles with just the rear deck done.

first off the is all pesronal prefrance. with that said if you want clean sound stick with a sealed box. sealed=quiter cleaner ported=loud as far as subs go one 10 will do the job but two in sterio is better sound quality. now rattles can be stoped by checking if everything is tight/not loose in the trunk. aslo from a preformance point of view mate its just add weight(alot of weight) for a little cleaner sound, so if you want it fast too skip the mate

you can run a pair of 8s if you just want really good sound and no rattles.

And don't use fatmat. That's garbage. Unless you want your car to rot so bad when it's hot out you practically vomit.

But really, there's no best size. It's all about the overall system. A pair of 10s on in a ported box might be louder than a pair of 12s in a sealed box. A pair of 10s with 1500 watts might be louder than a 15 with 1000 watts. One might sound better, one might cause more rattles. If you explained more about what you wanted to do exactly, it'd be more helpful than just the sizes...

8s with no raddle ha u shoulda seen my friends mazda windshield flexxing with 2 8s (jl w7)
but seriously u r right there is not best size its preference and application

yes its all preferance and application in this game but after reading more if he just wants a lil thump i suggest a fi x 10 or a dc audio lv 2 8 both ported to like 34

Im running a 12" MTX Thunder series 5500 in a ported box tuned to 33mhz, powered by a mono-block amp at 500watts RMS. It's barely cranked up at all and it hits hard enough to be uncomfortable, but i have it set at a good range.

Ive got the same subs but in a sealed box and a 500w mono Bazooka amp. It sounds great.

With 1 12" sub is all you need. Also depends what Kind of sub and amp are you hooking up. I used to have 2 12" Hifonic zues and it was impossible to store stuff in my trunk. 12" RE XXX is like having 2 Subwoofers in one

I was thinking of running one 12" sub in my cb7 to get a nice clean bass. Is a 12 too overpowering and will it rattle my trunk?

Its your preference, however if I may suggest, find your local jl dealer, tell them you want 2 entry level 8's, and an rms matched output amp, you will be more than happy, also a capacitor would enhance the sound even more,
a 12 is good, low, and clean, but imo, very overpowering. I was running 10" memphis, with 700 watt bazooka mono amp, and a 1.7 farad cap, and it would rattle your nuts loose, not to mention all the car parts now rattling, and I can't find half of them.......good luck, ultimately its your decision.......

I got mine and the guy that had it before me was a moron. It's got an Xplode head unit and 2 12" Xplodes in the trunk. Box is too small and I dont even know what amp is in it. I really dislike Sony but I do like the way it hits. Haven't had the car but 2 months so I'm still finding all the hidden crap. Dual 12's is the way to go though. I dont feel like mine is shakin apart but I could be wrong. LOTS of learning left to do.

It depends on what kind of music you listen to in all honesty. Hip hop you can deal with bigger subs with more "room" to move and if you like rock you'll probably like more punchy 10"
