I just put in 4 Sundown SA 15 D4. All parallel to 0.5 ohms.....I would like to know what would be a good amp for a good price to put on em. I had them on a brutus 1700d1 for a few minutes, and they were sounding pretty nice. I was thinking to get 2 of those and putting them on a pair @ 1 ohm. Just wondering what are my options. I would also like to get a smaller amp in the same series for my compnents. Thanks for the insight!
