Hey there, no I only have one battery, it just happens to be in a 2008 Chevrolet cobalt LS where they put them at in this model year, only 1 battery.Is this a 2nd Batt you are using?? If so I would connect it In parallel with your front battery and use #2awg min. To go from front to back batteries. Also a good battery isolator and a good in line fuse will be needed. Then Use #8-#10awg wire from the 2nd batt to the radio. All your wire can be bought at Best Buy in the car stereo section or from EBay. The reason for larger wire is loss due to length in this case. So the longer the run the bigger I'd go with power. If only 1 battery is being used and it just happens to mount in trunk, use #8-#6awg IMO, or larger. Yes it may be overkill to many, but if you ever want to upgrade you don't have to pull in larger wire next go round. You'll end up spending less doing it right the first time. Again, this is JMHO, as if any of you are like me, just one radio in the mobile isn't going to cut it for real long. Or should I say, you see a new radio come out of the one you always wanted type deal!! You get the picture.
As far as where you terminate the ground, IMO, keep it short as possible and take it to a frame ground. Again, some will disagree and tell you to take both POS and NEG to battery, some say short as possible and to the frame. Either seat bolt or under the dash where steering column comes through is a good spot to ground to for radio ground. Same if adding a 2nd Batt. Keep tie ground lead as short as possible and directly to the frame. Use no-ox on all connections!! And be safe!!
Ok,quick question, so far I have heard everyone suggest the battery route, I have no desire to run a amp,tried it in the past and was more a pain in the ass to hook up ,didn't really use it that much ,was looking at the fuse block, can I power it up thru safely,I had a Galaxy 88,Ranger 66 that I used the fuse block and never had any problems, could I assume the Ranger2950Dx could be hooked up the same?? I mean if I have to use the battery I will, just trying to keep it simple like my last installs,which all used the fuse box to get power,except my last Ranger 2960JP which was straight to the battery due to having a built-in 150 amp,all my other installs were with the fuse box, thank you for your help, paientence and input!!!!222DBFL is right on. Go with the heavy 8-10 ga wire. You can add an amp later and not have to worry about the power draw unless you get crazy with the power amp. But I would run both the ground and power wires together. The two wires side by side will counter act the inductance of just the one wire laying next to the car chassis. It will help stop a possible oscillation or ringing problem. Not endorsing any vendor in particular but I did purchase mine here:

You might get away with doing it that way, going to the fuse box, but one day you're going to have issues doing this. Trust me here!! Your vehicles internal fuse box is just that for the vehicle!! Add a seperate run of power for your radio and ground it to the frame. It's the correct way to do it. JMHO. Running a seperate power wire for your radio that is, and keeping out of the fuse box of the vehicle. Again, JMHO. A run of #8 or even #6awg from the battery to the radio with a fuse block at the battery and good connection for ground to frame is your best bet IMO. But it's not my radio or my vehicle so all I can do is tell you the way is do it. I the end you'll have to make your own decision about how to run the radios power. Do some reading on the subject you're asking about and it might shed some light as to why I am saying what I am. Good luck and be safe!![/QU Thank you,iam going to stop by Best Buy this week and get the necessary wire and item's to do it right, don't feel like blowing up my radio or my car or myself in the car by taking the easy way out, Thank you for your help!!!!
Save your self.....GO TO THE BATTERY......That way we will NEVER have to hear of you frying your car/radio because your fuse box fried. It's real EZ to just pull some wire, and remember to run that wire in some flex conduit, you can get it when you get your wire. Good luck, you have a nice new rig!Ok,quick question, so far I have heard everyone suggest the battery route, I have no desire to run a amp,tried it in the past and was more a pain in the ass to hook up ,didn't really use it that much ,was looking at the fuse block, can I power it up thru safely,I had a Galaxy 88,Ranger 66 that I used the fuse block and never had any problems, could I assume the Ranger2950Dx could be hooked up the same??

Thanks for the advice, the Ranger2950Dx pulls 7 amps so I have read.The main reason besides the availability of extra power you get less of a voltage drop when you key up and you will not affect the computer in your car. I have seen cars start to misfire and then shut down. The RF can overload sensitive sensors inputs to the computer and wreak havoc. If the radio draws less than 75 watts you could possibly run it off of the cigarette lighter socket. But the voltage drop and the potential to interfere with the computer are increased. It's just better to hit the battery. I use terminal strips to break out the power for the different items. I don't run amps but I do have some radios that will really punch out a big signal. The terminal strips get installed in locations in which nothing can short them out. I leave the high amp fuses in the power cables and also the standard fuses in the unit power cables. I do a little more with ferrite beads and decoupling capacitors.
Also I do not allow the radio equipment to remain energized while starting or shutting the vehicle off. Inductive kick can kill your radio and amplifiers
