JBL 1201.1 with a single Brahma 12

That amp is used very successfully on Brahma's by quite a few people.  But there are some quirks you need to know.  First of all, that amp doesn't have a subsonic filter.  So if you are planning on porting the sub with a high tuning frequency, you will need to get one.  Also, the gain structure is a little wierd.  If your head unit has 4 volt outputs, you will need the gain on the amplifier turned all the way down otherwise you will clip the signal and can easily hurt the sub.  Especially since that amplifier is a little under rated.  You have more than enough power as is to hurt a Brahma in a decent sized enclosure.  So be careful.  I've fixed too many Brahma's murdered by people with that amp and not knowing how to set it up properly. 

One suggestion though is to get a higher end amp.  You have a very high end sub, so powering it with a low end amp doesn't make too much sense.  Although I'm sure you will be happy with teh JBL amp, you might want to consider a better amplifier.  They usually have better warranties, features, and protection on them.
