My buddy came to me for advice on a little build he had. He works/worked at a local shop that carries and sells a lot of Kicker/Alpine/Fosgate. He said he only had 7" total max depth and 500w. I immediately thought of the Sundown SD.
After it went in on a little Kicker 500w, he said... "I will never use anything other than Sundown again."
Lol. I don't blame him. For a single 10 on 500w it is killing it.
Box is for a '96 Chevy full size single cab. 1.2 net @ 32hz with 12 sq in of port. All legrooom stayed intact.
