Excellent Product!

The following review is for XKIT84, which is a part of the bundle you are viewing.

I did a lot of researching around when I was looking for a 4 channel amp wiring kit, and I started noticing NVX products popping up quite frequently. I couldn't be more happy with this kit and the quality of the NVX products. The "Flexibility" in the wiring is really something you have to feel and NVX does such a good job with packaging, presentation, and making you feel like this is a high quality product. The design of this product is like nothing I have seen in amplifier wiring and I have really bought into this brand after purchasing a few of their products.

Very good kit and great product install options

The following review is for XKIT84, which is a part of the bundle you are viewing.

So this kit gave me everything I needed minus a ground wire. I mounted this in the midcabin section of my boat so I needed at least a 20ft piece of ground. Aside from that the kit was perfect for everything I needed. Really liked the additional speaker wire because I ran out by about 15 feet prior to completion. Would definitely recommend the kit.

Great but got shorted on wire....

The following review is for XKIT84, which is a part of the bundle you are viewing.

I would recommend this... It comes in a great display and has clean sound.... Only problem I had was it says that it comes with 65ft of speaker cable and I only recieved about 30..... I had to go out and buy an extra 20 or so feet of a different brand to have enough to wire my 4 doors... Other than that, it's fine....

It does the job

The following review is for XKIT84, which is a part of the bundle you are viewing.

Bought this as a bundle deal with my amp. Great wire. Had it installed for a $100 by a professional. And yes it was done professionally. Only thing it doesn't come with us a battery clip. A minor expense $10 at Max at Walmart.

Great Product for entry level setup!

The following review is for KTP-445U, which is a part of the bundle you are viewing.

After building several full all out setups on my previous vehicles, I wanted to try a more simple build for my current car since I don't want to spend too much time running new wire, mounting amps, etc. and I do not have the luxury of putting a sub since I need the cargo space for work.

I was hesitant getting this amp since I thought it would only give a little more than an aftermarket headunit and heat up, but I really liked the size of it (tucked behind the glovebox) and how simple it is to wire it up. I installed it today with a pioneer headunit, JL TR components in front, JL TR coax in rear, all doors deadened, gave it a good tune by ear and to my surprise it sounds great! Well 50x better than my base unit and stock speakers.

The sound is nice and clear, has a good thump, no noise or muddy sound and I can hear all the sounds I was looking for (just over 1/2 gain) that my stock stuff could not even come close to producing. I definitely recommend this amp to anyone who is looking to do a simple upgrade on their system without the hassle of running new wire and looking for a place to mount or hide a traditional sized amp!

powerpack

The following review is for KTP-445U, which is a part of the bundle you are viewing.

decent enough for small speakers for someone just starting out and doesnt wish to upgrade battery or alternator or run amp kits, however you get what you pay for and because its not an actual 4 chan or 6 chan amp dont expect the same sound quality or power coming from this little fella. value wise its pretty good and easy to install. might cause engine whine if you have to use a in line converter or data module for your specific vehicle.

Nice little amp

The following review is for KTP-445U, which is a part of the bundle you are viewing.

This amp is perfect for small places, or to hide easily where not seen. Produces big sound in a small package and a great value. I love it.
