How about you add some helpful input or shut the fuck up. I apologize for coming across as a prick, but all T5wagon does is spew out crap about skar, no matter what it is, it's the best. ---- OP, it's very hard to gauge one's idea of SQ and loudness, as it's all relative, so many variables even aside from the equipment being used. Are you able to build your own enclosure, or are you having a shop do it? I would try a new box for your alpine, you may just find that they actually do sound really good with significantly more output. If it still isn't enough, then pull out the alpine and try another driver. Or save a few extra bucks and pick up some Fi ssds, or higher end used drivers is always a possibility. But firstly I would try a new enclosure (one that could also work with new drivers in case you decide the alpines aren't enough.) Just my two cents.
