Don't judge a speaker on it'* size, or call it a 12

My 2 10" are plenty loud, and since i have a proper amp, and setup, better then most 12" systems.

haha i helped my friend who has a ford explorer sport wire some new 4 gauge wireing in his ride and i put in my two 12" infinity perfects (he used to have 15"* and his friend also has 15"*) and he says that it sounds like two 15"* haha yah and my system plays more clean but just as loud as my friends who run 15" subs. So yah it all depends on what you get and what your set up is.

wow you guys are being a biiiig help. well... what are some factors that make it a good setup? what should i be comparing between subs and amps? what companies are worth it right now? but also affordable... not made of the cash. honestly, just offer advice on what i should be looking for if you dont mind.

jasons right to an extent...id go with sealed..i had a bandpass...didnt like it...and buy an amp that matches your subs...and if your scrapped for money..w.ait a month or two..never buy less because you'll always want more!!! ALWAYS! if new brands are cheap and put out a lot...buy it...cuz you can always buy 2....2 1000w amps made by some new brand is better than 1 rockford that puts out 1000 x 2 and costs more than the two combine (if tha tmakes sence)

it does make sense. but what makes it match the sub?

an amp that puts out an rms that is the same as your sub rms
