Wire for hard wiring 1000w power inverter

I want to hard wire a 1000w power inverter in my XJ. I think the only open spot for mounting is under the steering column. I figure it will require about 13' of wire to go from the battery to the steering column. My plan was to use two runs of 6 AWG wire from Lowe's. However, the guy at Lowe's said he didn't think their wire was what I wanted. Is the wire at Lowe's good enough? The cable I've found online is way more expensive.

The wire from Lowes will most likely be solid or contain very few strands, making it very difficult to work with, especially in a vehicle.

Find welding wire and either solder on or crimp on proper lugs. If you can't find the tools to crimp on lugs you may have luck in a West Marine. If you buy their lugs they'll usually either let you crimp them on yourself or do it for you. Make sure to use heatshrink or electrical tape to minimize the exposed length of the connector to prevent shorting and also to waterproof the space between the lug and the insulation.

And don't forget to install a fuse next to the battery. The manual for the inverter will recommend a size.

Go to a local car audio place, ask them for rope wire or high strand amp wire.
You're going to want something around 6gauge, high strand count, gold\copper coated connections.

Also, why would you wire it under your steering column?

The inverter would mount under the dash by the steering column. I guess I don't understand your question. It can't be mounted in the engine compartment due to heat.

not only heat but also moisture. water and electric dont mix. to figure out how much wire you need take a piece of rope and run it from the battery along the route you plan on running the wire then just measure the rope. what is the model number of your inverter? if its 1kw running your going to need BIG wire, if its just 1k serge then you wont need as large a wire.

^ Mounting an inverter in the engine compartment isn't a good idea due to exposure to the elements.

Best place would be either under your seat mounted so that the cooling fan blows backward or forward, or in the spare wheel well with vents cut in the spare wheel well cover.

Dude.

Go to a local car audio shop.
Tell them you have a 500watt RMS amp you want to run that tops out at around 1000 watts peak power.

You need ground wire as well as the power wire, they'll hook you up with the size and braid you need to support it.

I'm not bull****ting you, the only thing someone else might chime in with is a wiring kit. Well most wiring kits have ****ty wire and terrible crimp connections. A Car Audio store will have what you need.

No problem at all, most audio shops will sell wire by the foot which is what you want.

You can also check EBAY for your wire look for amp install kits 4ga. I think under a seat will be a great place for your install i have a 750 watt unit under the back set of my JK and a 2100 watt unit under the back seat of my dodge ram

a 500w amp install kit isnt going to be large enough. B&D states for a permanent install within 6ft of the battery to use 2awg wire. a 500w kit is only 8awg and your making a longer than 6ft run.

Yes it is, if you notice I said A 500watt RMS amplifier with a 1000 watt peak. I would bet my jeep that he won't be pulling a 500 watt continuous load through that inverter. However you do bring up a good point about the length of wire VS thickness, if he runs it to the rear of the jeep he would need something close to 2ga, IF he plans on running a continuous load of 500watts.

The issue with amp wire kits is that they often use thick housing on the wire to make it '4ga' wire, when in fact, the wire inside the housing is only 10ga or even thinner.

I would use 4AWG like some suggested. Rule of thumb is always install cables rated for the the inverters continuous power rating, just to be on the safe side. DCACpowerinverters makes a very good cable kit for a fair price........

How about this:

http://shop.genuinedealz.com/Items/I...re%20BLK%20/ft

Marine Grade Wire > Marine Battery Cable | 4 AWG Battery Cable UL
4 AWG Tinned Marine Battery Cable Boat Wire BLK /ft
This item sold by the foot in a continuous length

Price: $1.97 per foot


One of the primary concerns of professional technicians is cable flexibility. Marine applications are characteristically in enclosed areas with sharp turns. The less flexible the cable, the more difficult the job will be. The two factors effecting a cable’s softness are its stranding and its insulation. Our UL listed marine battery cable is made of type III rope stranded tinned copper and is insulated with a pliable yet durable, specially formulated compound. It maintains key physical and electrical resistance properties while providing sure power delivery and unparalleled quality. The electro plated tinned copper resists corrosion, extending the life of your cables and connected equipment.

FEATURES:
• Finely stranded tinned copper conductor (Type III)
• Color coded PVC insulation (See chart for specifics per gauge)
• Temperature Range: -20°C to 105°C
• Voltage Rating: 600V
• Resistant To: Acid, Alkalis, Abrasion, Flame, Gasoline, Oil, Ozone, Moisture, Fungus
• Applications: Connecting battery or generator to switch, starter or ground Windlass, Inverter or any high amperage equipment

COMPLIANCES:
UL Standard 1426 (BC-5W2)
AWM 1232/1283 (6-2 AWG)
AWM 1232/1284 (1 AWG - 4/0)
