NVXNDA6004 1200W Peak (600W RMS) N-Series Class-D 4-Channel Amplifier

This 5 channel amp puts out a lot of power for it's compact size. I added this to a Kenwood KMM-BT332U head unit paired with some old Phoenix Gold 5.5" speakers and an 8" Kicker sub and it sounds fantastic. I'm sure it could easily drive 6.5" and a 10" subwoofer. With out the amp the speakers sounded terrible. The extra knob for the sub is nice but I'm not currently using it.

this amp SLAMS its mounted behind a seat and doesn't overheat. i drive 12 hours days doing uber. great unit

TL;DR - this is a fine little amp that makes an easy upgrade for the numerous old Lexus & Toyota cars with the factory amp behind the glove box - by installing this IN the glove box where I have quick access to the factory speaker wiring. Also, it's an easy place to route 12v power to the amp alongside the wire bundle headed to the ECU through the firewall. Even with the factory speakers still in place ("the best speaker upgrade is a new amp!"), the music sounds great!First impressions: The NVX NDA11005 has Plenty of power for discerning listeners. 'no static at all...' . I also like the solid connections and compact size of this amp!TMI - In my new car stereo installation, I had just upgraded the lexus factory amp to a Soundstream PN5.640D 5-channel driving the 4 OEM door speakers and subwoofer in the rear window deck. It stopped turning on after a week or so - we (their tech support and I) suspected the flimsy dongle/harness that combines the remote turn-on and the remote Bass Boost adjust dial - and I was having a hassle getting a prompt replacement, so I looked for alternatives of the same size and found this NVX NDA11005. It's smaller, more powerful, has cleaner audio specs and has MUCH better connections for remote amp turn-on and with PROPER RCA inputs; solid power, ground and sub connectors, etc. The Picasso's going back for a refund.After a 60 minute drive at freeway listening volume with the NVX NDA11005, the unit merely felt warm.So far, so good!Update: The amp is now driving the factory door speakers (all 4ohm Pioneers) and two subwoofers connected in parallel in the trunk: an 8" Infinity KAPPA 800W hanging 'free air' where the factory subwoofer was, and a sealed-boxed 10" Alphasonik doing the down-fire thump underneath it. Both are 4ohm SVC subwoofers rated for 400W RMS, and I'm hearing them improve with early usage! Amp's still running cool!

While the amp seemed promising and I have owned other NVX products this amp was terrible right out of the box. After 10mins of playing at less than 40% the amp began to smoke. No protection just the smell of burning electrical components filled my trunk. So hours of operation less than 15mins. Contacted Amazon and was informed while I bought it in Jan and didn't install it until mod February, the amp was past 30 days so I had to work with their after marketplace sales team. This is when I was informed I would have to ship in my amp after they got an RMA for me and that they would then ship a replacement. I needed to pay to ship the broken one to them but then I would need to wait for a replacement. So now I sit waiting. Since February 22nd I have sent 5 emails asking for status updates. I confirmed the package was delivered to their return center via my tracking but they have yet to respond to me. So I called and was told they can't do any support via the phone but someone would respond via email today. Which just like before nothingReally frustrated as they seemed to be a good up and up company from prior purchases.Hope they sort this out soon.

I’ve had for almost a year. Solid starter amp. Bass knob could use some help.

This amp is a Polk audio company product . I have this amp powering 1 skar audios top model 12” competition sub with an rms of 3500k watts. I have this amp wired to 1 ohm and man does it deliver power . I’ve had kicker amps Rockford fosgate and alpine amps and for the price I’d take this amp any time over those . The bass is clear and hits hard and this amp doesn’t heat up much at all. There is no on board fuses but has a protection mode to protect your equipment. I give this amp a 10/10.Update: after breaking in my monolith sub for a couple weeks and the amplifier I had my sub wired to one ohm . The next day this amp couldn’t handle the load and almost damaged my entire set up however my mid range amp immediately went into protection and this amp stayed on even after my car was off had to disconnect the remote wire and it still stayed on. That tells me something was defective in this amp. Amazon is shipping me a new one . Hopefully it was just this amp. My installation company tested another brand amp on my set up and had no issues so it’s definitely the amp.I got a replacement amp same one and it’s working perfectly fine now and no obnoxious heat from the amp . I still have it at one ohm . I think the first amp I got had some underlying issues but was hassle free getting a replacement amp and I really like this amp and it’s a monster. My sub if fully broken in and I have this amp tuned perfectly and I upgraded to zero guage and added a capacitor. This amp is truly remarkable and sounds great

Great product. Successful transaction.
