Posted August 16, 200916 yr Recently getting involved with Sundown as a dealer in Florida, I sold my entire JL setup and switched to Sundown amps and subs. Jacob worked hand in hand with finding a good fit for my small BMW 318i.I installed 2 Sundown SA 12" subs on a Sundown 1500 Watt Amp. They are wired to 1ohm and run extremely well. The ported box is tuned to about 34hz, and i am very pleased with how the subs are responding. These subs will blow so many other setups out of the water! I am proud to say more amps will be going into my car and I look forward to selling a quality product!Kevin
