It's been 9 days since I have paid fur my sub and every day I call them and they say we are shipping it out today what happen to the fastest shipping

Best sub by far I’ve had deaf bonce for awhile and switched to Sundown and man Sundown by a land slide!!!!

All I can say is wow…what a subwoofer…this thing is huge..by far and I mean by far the best subwoofer I ever had…just bought 2 and let me tell you I have the on an 8k sfb sundown and these guys are sucking the life right out of the amp…from Deaf Bonce what I previously had to Sundown…sundown WINS….by far…thank JP and staff for the service……

This sub is extremely good for the money and will take a beating, break in easy and you will not be disappointed. Pushing it with a D4S JP 23v2 and is a great combo.

I wanted to upgraded my system from 4x 15s Q-Class Kickers to Zv5 but there wasnt any in stock so i got 4 of these. These speakers are awesome and a great buy. I'm never going back to kickers and highly recommend this or Zv5 if you can find them.

For years I’ve wanted the X series the xv2 was a great looking subwoofer but when the v3 was released I had to get 2 of em on a crossfire 4k I love these beefy subs.

These things are insane only wish I had room for two more

This is my second sundown x15 the first one was the v2 that my friend recommended me i used different brand from jl, alpine kicker but sundown is the best among the other ones that i had before that was the reason to get another one and the price and fast shipping was amazing thanks down 4 sound looking to get more stuff hopefully very soon

These subs are "strong". I have them on a sfb 8000 and I believe they could handle even more. Great subs....

Ill start by saying im all inn when it comes to anything electrical if its AC VOLTAGE or DC VOLTAGE i love learning more everyday sec of the day I installed for years and always been a fan of 12” subwoofers my setup is in a 2008 Chevy impala ltz 3.9 im only running my 250amp alternator right now but i need the time to swap out to my 320amp alternator.Back to the subs i can say Im satisfied i went with 15s I purchased two of them I only have one hooked up in my car and its doing more than I expected I haven’t even installed my new high output 320 amp alternator yet and one sub is doing great and unexpected performance is all i got i had it installed for only about a week and a half after I built my enclosures for each of them can’t wait to run both these subs they GREAT.Ill be sending you a video when im finished up with my setup thank you to the main people JP & the crew from SUNDOWN AUDIO & D0WN4$0UND You guys got the best job in the world in my eyes
