this auction is for a used, alpine mrv-1005 650 watt 2 channel sound quality amp made in korea.

they were assembled in korea and made in japan. if you look at korean and japanese boards,

they look the same. it works perfectly.

this, in my opinion, was alpinee best series of amps that they ever built.

this amp does:
