Key Features

2 Gauge High Power Amplifier Wiring Kit 3800W - Juice Car Audio JWTRU21

You should never underestimate the importance of a good wiring kit for your amp. Using lower quality cheap unbranded wiring kits can cause your system to fail/underperform. Think of filling a bucket with water, the hose you are using has multiple holes throughout the pipe, or is simple too small, how would you fill your bucket? The bucket, is filling but not efficiently. Having bad quality cables has the same effect. The hose is the cables and the bucket your amp. In order for your amplifier to deliver its best performance you need the best cables. 

It does not matter if your amp if £50 or £1000, the cables are just as important. Badly insulated cables will become hot and potentially cause a fire.

British Design

All Juice products are designed in the UK by audio experts who have studied and listened in detail to audio for over a combined period of 200+ years. So, they know a thing a or two about what things are supposed to sound like!

"TRU" Gauge Wiring

Unlike cheaper alternatives you will find on eBay and Amazon, the Juice TRU series are true to the gauge advertised. A lot of unbranded/cheap cables you will see on eBay and Amazon will state 10/8/4/2/0 gauge, which is the size of the cable including insulation. The Juice TRU are the specific gauge BEFORE insulation is taken into account. So, there is no downturn in performance, audio quality or interference.  

Twisted RCA Cables

This kit contains shielded RCA cables which are tightly twisted for extra shielding to ultimately reduce signal loss and interference.

Gold Plated Terminals

Gold plated terminals improve the conductivity, this provides great power transfer and corrosion resistant. These also give your install a nice, polished finish.

Manager's comments

"The benefits are huge, by having correct good quality cables as the heart of your system you will enjoy better power output, less interference and keep all your audio products working in good health. The price of this kit is insignificant compared to the cost of replacing bad cables, an amplifier or even worse, replacing damaged vehicle electrics. At the heart of a good sound system, is the amplifier. Varying voltage, current and bad grounding will cause the amp to run inefficiently and eventually you will have clipping/bad performance."

A nice wiring kit apart from cheap connectors
BRENDON on 20/11/2021 3 star rating

This wiring kit is fantastic, Only gripe is , for a £70 wiring kit is has everything you need wire wise , But the ends in the box look and feel very cheap and I did not use them , They where also VERY thin and just didn't feel good enough too use , Also everything from the fuse backwards is idea , but what is missing is the connections and wire from the fusebox too the battery, So in other words the kit is good quality apart from the cheap connectors they put in this kit ,

Superb kit but does need more ring terminals
Dizzy on 18/03/2021 5 star rating

So I Bought this kit as I'm always a firm believer in the bigger the better when it comes to cable size. This kit did not disappoint, you do need to check where you will be running it to ensure you have space for this cable but I had made holes for this so it was fine. Someone had previously mentioned that there was no speaker wire in their pack, I can tell you I got a hefty amount of speaker wire in mine and it was nice chunky stuff to ensure a decent signal. There were only two ring connectors provided which is not enough when you have a fuse block to hook into as well, so if you order this kit, order a couple of extra connectors as well. Still, all in all I would give this kit 5 stars based on the quality, certainly not the cheapest kit but one of the best I've found.

Quality products but advertising wrong.
Owen on 30/04/2020 3 star rating

The quality of these are great but In the key features section it states that it has gold plated ring terminals but when it arrived the packaging has no mention about gold plated ring terminals and did not contain any. Without them I was unable to finish fitting my amp.
