Hi, new to the forum. Name is Jonathan and I'm from Colorado Springs. Been into car audio for years, and I am starting a new build in my 2001 VW golf. I had been running 2 power 800a2s with 2 15 inch Punch HX2s, but kept smoking coils on those subs. I've gutted most of the old equipment, and I am going to start fresh and try out Sundown Audio subs. I hear the SA-15s are a solid woofer and should handle my amps with no problem. Cheers
