I’m currently in the market for Sundown subs. My diamond sub blew after 5 years and I wanted to upgrade my amp and sub. I just bought the 15th anniversary Sundown SAZ-1500D amp and now I’m looking to pair it with Sundown subs. I was looking at the 12 inch SA v2. I want to get 2 of those or just 1-12 inch U sub. If I get either of them should I get 4 ohm or 2 ohm. I have an upgraded alternator with the big 3 upgrade as well so power isn’t an issue. Just looking for some advice! Please and Thank you!
