Review: The kit is great! I’m guessing the lowered ratings for the fuse was given by people that didn’t know to remove the emblem on the fuse casing and tighten the fuse in it with the tool provided. I thought it worked very well pushing power to my dual Rockford Fosgate punch P3 12’s, and my Rockford Fosgate P1000xbd mono amp. Which the amp is certified at 1477 watts. No issues at all, and highly recommended.

## Questions & Answers

**Q: I do t get what holds the fuse in, its loose and will wiggle out over time, what am I missing?**
A: If you look at the picture, you can see the red power cable. At the very top center of the picture is a gray plastic container (approx 6-8" from the end of the power cable). That is the fuse container.  The fuse is inside and can't wiggle out.

**Q: How much speaker wire do you get?**
A: Kit includes 17 feet of 8 AWG power wire, 3 foot of 8 AWG ground wire, 30 feet of 16 AWG speaker wire, (1) 16 feet twisted pair RCA, AGU fuse holder and fuse, 20 feet of remote wire, 40 Amp fuse.

**Q: Is this enough wire to run for a f150 supercab ?**
A: I am inclined to say yes, but to be sure, you should measure. You need to figure out where you are going to mount your amplifier, and how you plan on routing your power cable. There is 17/18 feet. of Power cable provided, so this is usually sufficient... but I would measure just to be safe.

**Q: Does this come with rca cables?**
A: 16 guage cables

As with everything on Amazon I plan ahead. So if I know I need something I'll add it to my cart and let it sit there since prices tend to change often. When I added it to my cart it was around 85$. A couple weeks later I got an alert saying the price decreased so I went to check and it had dropped to 67$ shipped and sold by Amazon with prime shipping. Usually when an already low priced item such as this drops that much I scoop it up right then and there. Savings of 18$. As far as the actual kit, it is probably the best quality 4 gauge kit out there for the price. It is definitely true 4 gauge with decent insulation and it is actually truly copper in and out, no aluminum. Very flexible and easy to run in car. Perfect length from battery to trunk and I own a fairly long sedan, BMW 750li. I like the fact that they already installed the fuse holder and fuse but rarely is the fuse the right size. Too many companies rate their kits on wattage and that's not the right way to go. So 100 amp fuse is too large for my setup as my amp has an 80 amp rating so I had to go out and buy an 80amp fuse. As far as the fuse holder it is decent. Not the best but not the worst. Took a bit of work to remove the rubber piece on top of the holder to get to the Allen screws but once tightened the fuse doesn't go anywhere, no chance of moving and wiggling around like many have complained. I didn't use the rcas so I can't comment on the quality but when I first started my system I used a cheap scosche kit from Walmart and the rcas were decent, I never got any noise or anything out of them. These look of similar quality if not better with the RF brand but they only give you one pair and I needed 2 pair so I just put them aside and bought 4 channel stinger cables and they're awesome. I also didn't use the speaker cable because I don't use 16awg speaker wire, I think it's a little too small. It's also only aluminum not copper. I use monoprice 12awg oxygen free copper which may be a little overkill but it's not too expensive and it works perfect. Ground is perfect length even though I only needed 12 inches. Shorter the better. I would definitely recommend this kit to anyone. I know it's common to be on a high school budget but spend a little more now and get better quality because there honestly is a difference in sound and output.
