Hello all, the name is Jacob here, and sparky is the build.
I am working with a 2014 Chevrolet Spark 2LT. I had a single Sundown SA-12 D4 in a 1ft^3 box, running on an old school Alpine MRV-T707. Scored 134.8 on the windshield. Box was a bit small, and the amp wasn't even tickling the sub.
Current plans are to go to a pair of SA8 D2s in a Q bomb, with an SAE 1k at 2 ohms. Will be sure to share progress.
