I was wondering if had lets say four cheaper subwoofers, would they be louder than two decent subs? Ok, so would four of these pioneer premiers:

be louder than two of these Orion HCCA's:

And also, would three of those Premier's be louder than the HCCA's.
to answer this question is so simple , ok just look into some spl comps and see what people are pulling up the big #'s with. Definitely not 4 800 watt rms pioneer subs , i'll take the hcca's over the pioneers any day ,,, o and two orion hcca's are hitting 154.7to 157.5 bd spl your lucky to get 147bd with the 4 pioneers,,now if your looking for loud subs and not so worried about price get your self a FI you can get them custom built to you liking for about 500 and smoke the competition, just look into some comps.or the usac records … FI's btl , Orion'sHCCA and RE audio's MT's , these are the subwoofers to own.

Vr3 12″ subwoofer with dual voice coil. the sub is 20 bucks and the amp (Vr3) is 50. cheap not so high quality stuff but this is really nice for the price. yes it is walmart cheapo. the sub is only 40wrms per coil and the amp is 50wrms per chennel. 1 coil per channel. it is a max of about 90db (give or take) at peak performance. it is sealed at probably 1 cube. dont really know the measures this is just a system for really poor people. it works great though
AMAZING!
deepest bass ever it might destroy a cheap subwoofer
these are cheap subs rated for 1000 watts peak power. they sound way better than i thought they would. they rattle my whole car. I traded this car in for a dodge durango. When I get these Subs installed in my durango I will post a video of them.
