Dont even waste your time buying this amp didnt even make it one song perfect 12v and ground connections on both inputs cut out mid song not even 1/4 gain now constant pwr and clip light multiple reviews on here and facebook have the same probs they are made from china anyway so i should have known better dont buy this junk Skar is better than this

I need to send this amp back, it literally burnt out on me yesterday. I went to install it played for about 10 minute started my tuning and adjustments and one side of the amp jus started sparking. Turned the truck off 2 check and nothin was touching . Double checked EVERYTHING and everything was fine. Installed another amp I had and it was fine

3rd one of thes ive bought and they always do me right

I’m highly impressed by the power this amp puts out. I’m running 2 15’s vfx’s and with the gain at quarter turn it knocks pictures off the wall. I love sundown audio. I’m looking forward to purchasing a 4 channel amp soon…

This is the worst amp I ever owned. This amp lasted 5 seconds before the clip light came on and no sound. The amp wasn't warm and I get nothing, I unhooked by subs still no sound and clip light is on. What a waste of time spending upgrading all the wire to 2/0 sky high wire, 320 alt and two DFS lithium batteries. When I get it back from warranty I will sell it and take the loss. I would rather own a flee market amp that this don't buy

I bought this to power two u12’s upgrading from a 3k and it made a major difference! Previously I metered a 140 and now I’m at 147 ! Giving these subs what they needed!

My brother bought the 8k and it is an abuse beast of an amp, so I decided to but the 5k. It's an amazing amp. I'd always wanted to order from D4S so I contacted them directly before purchasing and the customer service was great. They're very nice and knowledgeable. I'll be ordering from D4S in the future.

Love it

Still waiting on a box so i cannot leave a product review just yet, however i know this will be complete overkill along with dual battery, mechman 400a - for a couple q class 8's that were previously purchased. really just wanted plenty of headroom and have options down the road. only downfall is the $100 price drop just a few days after purchase, but murphys law i suppose! Faaaaast shipping, included swag, and the personal touches on the recipt set this place apart though! thanks jp, and down4sound crew, ill be back for sure.

This amp is a BEAST! JP and D4S are the best in the business! I wouldn’t buy from anyone else! Thank you for signing my amp! Have a blessed and merry Christmas!
