xtant bought out by mtx had this amp for 3 years now. it's been through 3 cars and one serious accident. it's been wet,stomped on, dropped, and pushed way too hard. this thing is and always will be in my truck until it dies. i run my type r components now with it. my first 2 systems i had one channel bridged for subs and it even worked well for that. excellent, especially for components.
