Will these require any extra power, or will it work with the stock car power?

They seem to work fine with the stock. It sounds great! I have to mess with the equalizer on my head unit on some songs, but that's normal.

will hook up to your current power set up. may need/want a compatible wire harness to adapt speaker to vehicle wires without splice.

I hooked them up to my 21stock stereo and they sound great. No extra power needed.

I cannot answer that question. mine are wired directly to a four channel amp. all I can say is without an amp they will not put out as much. they will probably sound like your stock setup. get a separate amp for them. mine has the boss audio 4-channel 400 watt amp. cost me $40

No they can run off the head unit but if you amp them they can handle the additional power.

You will need to wire this into a 12volt power source. You could use the radios switched 12volt power to turn it on when you turn your car on.

If your car's 12V outlet works with the engine off it will. If you're going to be doing this for too long I would recommend againt it or you will end up with a dead battery.

Yes, they will work fine with that system and will be able to handle the power. I believe they would be a great addition to your surround system. I simply love the ones I purchased and have had no problems what so ever.

Anything that supplies USB power will work. Comes with a full size USB to Mini USB cable as well as the car lighter power adapter to Mini USB.

Well I don't know how familiar you are with cars but LEDS don't draw much power. With that being said you do not have to always wire them directly to the battery. If it is easier for you all you need is a 12volt source to tap into and a ground source. If you installed the control box inside the car the you could use the 12volt memory wire behind your radio to power the underglow kit. If it's an aftermarket radio most of the time the wire is yellow. For the ground the wire should be black on an after market radio.

If you have something to power them with, I don't see why that would be an issue. The cords are pretty long but depending on how big your boat is you many want to get some extra wiring.

As long as you can get power to your dash, it will work. I've used it without starting my car.

They will work, if the radio amp has sufficent power to drive them. Check power output on the radio data.

I have them running off a 12 VDC battery in a vehicle, which is around 13.8 volts DC. If you use a 12 volt DC power supply it will work. MAke sure the output current of the power supply is sufficient to power to lights. IN other words, do not use a very small plug-in 12VDC power supply. Use one that is at least the size of a normal men's wallet. If you use too small of a power supply it could overheat the power supply. THese lights work fantastic. Theyve been on my vehicle for over a year now and continue to work flawlessly.

Hi, this item compatible the GM cars (after 1996), and yes, it will power deniedto the device when you switched off.

it probley will work on a stock radio but best performance 1.2-2.5watt dead key and it will make the amp last longer also.

If you have a battery in your vehicle yes they will work. You may want to buy longer bolts for it.
