Review: Best all around daily sub - Delivery is fast . Sundown is quality made equipment. Sundown is very underrated subs. Perfect daily subs not needing huge box specs to sound great. Do not under power . Do not run if on stock electrical unless you have big 3 or 4 done with good lithium to support and it still eventually will need ho alternator. Can t go wrong buying sundown.
Review: Heavy Duty - Replacing an old Memphis Audio Mojo 12” that was twice the price. Magnet was from around 2008 and cone was replaced around 2014. Lots of hours! Running on a Kicker ZX1000.1 @ 2 ohms that tested 1230w rms @ 14.4 volts from the factory. I was skeptical of Sundown, especially for the price, but it exceeded my expectations. Terminals are bigger and can handle larger gauge wire. Leads going to voice coils are triple the size and the double stitching on surround looks very durable. Cleaner sounding than the Mojo at a higher volume. I would love to see what it sounds like with 1500rms. Highly recommend.
