I did an install in my friend's car with this phoenix gold sd800.5 under the passenger seat in an almera.I used infinity 6" coaxials and 6x9's which are 2ohm to obtain full power per channel as well as a memphis sub at 2ohm.it played really clean considering it just deck and amp and no external processors. it may not be totally mini but it has a small size with a decent amount of power and was really clean. For the price it was worth it, since the JL xd series was at least about $1300-$1500 more and i was working with a budget -paid $2000 by steve's elec. it also simplified the install with one amp.
