[QUOTE="stones, post: 1740, member: 540734"] The alpine should power a pair of 8700's quite well. I would go with the 8712.8's(8ohm coils) and parallel the coils, that way you will run the alpine at a 4ohm mono load(Alpine rates the 1507 to put out 900watts rms into a 4ohm mono load which is plenty for a pair of 8700's). Also a 1 farad capacitator would be a good idea, it will help ensure the amp has enough power to pound out long series of beats with flawless accuracy. A couple things to take note of is to ensure that you break in the subs before you do any spl testing(7 to 10 hours of moderate playing is recommended, or a month of daily cruising), and when tuning the cross over pionts and gains allow the subs to warm up first(let the voice coils warm up)because you will find that they deepen and get louder after about 15minutes of playing but seeing that you live down under(hot climate), that probably isnt really a concern.
