48TCWRT672 CompRT 6.75" subwoofer in Thin Profile Enclosure, 2ohm

Can't hit the lowest notes, but works great for it's size. Have two of them behind my seats.

Finally hooked this up to my truck. 2006 Silverado 2500 HD with stock Bose system. Removed the stock Bose subwoofer and center console. Replaced it with this and sounds better than the stock subwoofer. Placed it behind the passenger rear seat on a crew cab.

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.

Stock 1984 c-10 pickup radio, very muffled sound, no amp maybe required.

Just got it. Took it out of the box. Hooked up to my mono block amp. Nice thump. It sits literally under my rear seat in my 2005 f150 stx. You can't even see it because it doesn't stick out. Just opened the seat, layed down and put the seat down. Compact and good for the price will get another for the other side. Two thumbs up
