Shipping and Miscellaneous Item Information:

(Audiopipes) They are currently installed that's why I couldn't take the best pics of them but they're in perfect condition and have been barely used. 100% functional and I've had some great amps in the past and these are surprisingly good. Honestly, I was surprised.

(MTX) In great condition and 100% functional, I use it as a tweeter amp and it worked very well for that. It can be crossed over up to 8khz.

(MB Quart) Amps in decent cosmetic shape, I would say 6/10 or so. One of the metals rings around one of the RCA inputs comes out a little easy and is a little bent but the amp is still 100% functional and delivers a ton of power.
