Do you think 8 gauge wire is alright or should I go smaller?

From what I researched 4 gauge or 6 gauge on power line and ground, with a 80 to 100 amp fuse and at least 12 gauge on wire to subs. You can probably verify this with a stereo installer at Best Buy or calling Crutchfield to be safe. It's your car expend all avenues to make sure on your installation,on will it be fine if installed. You don't want any fires.

I used 16 gage and my system sounds fine. The thicker the wire is, the better. But I think 16 gage is fine for most applications.

I used 16 gauge with the terminals that are provided. If you want to go to a heavier wire, you can provide your own terminals which are readily available.

I would recommend 4 gauge for the power wire just in case you decide to change your amplifier you will not have to go back and run over the wires. However this is not a very powerful amplifier and I strongly suggest putting the extra money and buying a better amplifier. What are the 12" subs are you going to use?

Personally I would use 18 gauge wire, your load is less than 3 amps. 18 Ga wire is over engineered for the load and it has mechanical strength.

Should work perfectly fine with 2 gauge wire. They were a little tight with monster 0 gauge, which is a little oversized, but the allen bolts go all the way inside which should 2 gauge wire with no issues.

most systems at 12 volt use 10 amps or less of power. Therefore, 16 to 18 guage wire should work just fine.

I think 16 guage is the biggest wire it recommends. I would get something more heavy duty.

My wire is 18 gauge. The wire gauge doesn't matter as there isn't any current going through it. The coating on the outside needs to be able to be buried (ground contact wire) which this is. there isn't any stress on the wire so it doesn't need to be thick, thicker wire will be harder to use when installing. Bottom line don't worry about this wire. I installed this wire 15 years ago and only just needed to do it again since we re-landscaped our yard and tore up the old wire. I figured new wire was better than a bunch of splices. good luck.

I had to use 16 gauge because I had to feed four sets of wire through a very narrow space....speakers sound great. If you can use thicker, you should.

20 gauge is fine for short connections but I would use 16 or 18 for long runs. I used lamp cord (18 gauge) for about a ten foot run and it worked OK. If you use smaller wire for a long distance it will work but your light output will be diminished. For those who don't know - the smaller the wire the larger the gauge, so a 20 gauge wire is smaller than an 18 gauge wire. Think of electricity flowing through a wire like water flowing through a pipe - the bigger the pipe, the easier it is for water to flow through it.

You could use 8g but the amp can only intake a 10g. I just bought a 10g Rockford wiring kit as it extends the warranty on the amp from what i understood. Its a great amp by the way. Just mount in a area where it will get.air as it gets hot.

As I understand the bigger the wire the less draw and heat. You can use smaller but bigger provides better protection. I used a 0 gauges with in line fuse. A little struggle getting half inch thick wire through. But even if you have somthing small you can upgrade with out needing a bigger wire if it's already there. The wire I got was so thick it needed a slight trim but it's better to trim then have some little cheap wire melt and short. I never had a system before. It was much cheaper to do it my self. Check diagrams off of crutchfield. And videos off you tube. Everything you need to do it your self is available. Although it's good to gave a helper with big speakers.

Proper wire size is determined by the load (Amps) and length of wire needed. Search for "12v wire sizing chart" to see a breakdown. I use 16 gauge wire which will carry up to 5 Amps 15 feet with about 3% voltage drop.

I think a large would probably be too big. If you're in doubt, go smaller. The wires separate very easily and you don't want to let too many nuts back out. when you're bringing new ones in.

I would have to say 4 gauge at the max. I got a 0/1 gauge wire and had to cut a good bit just to get it to fit in. Mines still going strong good luck!(:

I can't remember how big the openings are because I don't have the amp anymore, however, if you already have 8 ran, might as well just use it. Trim the wire to size if you need to. Bigger is better than smaller
