Review: Rms is not what is listed here's why - I bought 2 of these boxes pretty pricey for what they are and they sound good but the issue is the rma power rating is wrong they can really only handle 100 rms each not 150 rms if you send them too much rms the passive radiator flaps and makes noise it's horrible if they can do away with the passive radiator it would be a decent box.
Review: Fits behind your seat - Can't hit the lowest notes, but works great for it's size. Have two of them behind my seats.
