First of all, please forgive my posting in this section, but I want to hear from Sundown guys why the product is better then the other two I am thinking of, instead of "it just is". A little on my background, I was pretty into car audio back around 1996-2001, but have been out of it since then. A LOT of things have changed since. I ran a Xtant X1001 and X604 in my last car for reference. In any case, I am looking to put together a pretty simple system now for personal use, no shows or competitions. The amps I am really considering are: Sundown SAZ1500D (used by Sundown guys, but with warranty) Hifonics Brutus BXI2608D Lanzar OptiDrive 2000D I will be running in a '06 Durango with stock alternator (160A), Optima battery, Big 3, 1/0 guage wire, and possibly a second battery and capacitor if absolutely necessary or strongly recommended. I would like to run either (3) RE Audio SE12's, Or (2) RE Audio SE15's, OR (2) FI Audio SSD15's, just have not yet made up mind (I am open to any suggestions on that as well). Can any of you give any input on the above options? They are all in the same price point, with the latter 2 being new vs. used on the Sundown. I really appreciate any advice and certainly mean nothing negative towards Sundown whatsoever by posting this in their forum. Thanks, ryan
