Title: Adding a 2nd Battery Post by: 2i2dk1ny2i3 on February 19, 2015, 05:16:42 AM anyone ever done it usually because of a Large Hi power Speaker System?
got most of the recommended, Capacitor for my current lonely 10" inch Sub (had 2 12's in the trunk but removed a while ago) still got another 12" in a ported box but the 10" inside the Cabin behind the Driver's seat provides enough Bass plus added free back massage What to do to give your car's electrical system a power-up Upgrading a car's electrical system: do you need the big 3? (http://www.crutchfield.com/S-5M9ocmJrULh/learn/learningcenter/car/stereo_power_ups.html) upgraded Wiring and made an Engine Ground Kit long time ago but don't see myself needing to upgrade Alternator since 1 10 inch Sub and Amp doesn't require it basically adding the 2nd Battery to the Trunk for any additional Electrical Mods picked up Battery and will update with pics Title: Re: Adding a 2nd Battery Post by: timot_one on February 19, 2015, 07:42:18 AM A lot of people have relocated their battery to the trunk, but not many have added batteries. It's easy enough to do with a battery isolator though.

It's easy enough to do with a battery isolator though. i like the look of mounting it where the Spare Tire was, doesn't take up any trunk space and puts some weight in the back for those of us who live in a true 4 Season State What kind of extra electrical mods are you planning that you will need a second battery? idk yet but one thing i wanna do is use the lower Center Bezel cigarette lighter somehow into the Rear center fold down Armrest i've had this removed for a while now and would like my Rear passengers to have a USB connected charger and not over burden the Main Armrest secondary Charger i.e. if there's 3 People in the Car, i'd like all 3 people to be able to charge their Phones. 3 including me since no one can sit behind me 2/the 10inch Sub and rarely have a Passenger back there Title: Re: Adding a 2nd Battery Post by: timot_one on February 24, 2015, 10:17:53 PM That's simple enough to do and would not require adding a second battery. Seems like it's more trouble than it's worth just to have a second battery in the trunk and a 3rd charging port for a back seat passenger.
They do have 12v/cigarette lighter chargers that have 2 USB outlets on them. I use one in my car. Title: Adding a 2nd Battery Post by: bhall109 on February 27, 2015, 08:59:35 PM Really only need an isolator if you plan to play your system with the car off.
I have a second and working on a 3rd Title: Re: Adding a 2nd Battery Post by: 2i2dk1ny2i3 on February 28, 2015, 06:51:40 AM That's simple enough to do and would not require adding a second battery.

They do have 12v/cigarette lighter chargers that have 2 USB outlets on them. I use one in my car. i intend to install more things then just USB Outlet :) mainly for peace of mind of not having to add another Electrical Mod on the Engine Battery Really only need an isolator if you plan to play your system with the car off. I have a second and working on a 3rd pics? Battery Box arrived!, went w/Marine Attwood Battery Box: (sry about camera pics but its been single digits here so quickest way to take pics) (http://i790.photobucket.com/albums/yy186/GR3Y5H3ART/IMG_20150227_215521.jpg) (http://i790.photobucket.com/albums/yy186/GR3Y5H3ART/IMG_20150227_215529.jpg) Battery, Battery Terminals, Battery Box...right side of trunk: (http://i790.photobucket.com/albums/yy186/GR3Y5H3ART/IMG_20150227_220000.jpg) with Strap on and secure. i covered the 2 holes w/electrical tape since sometimes when i open my trunk, specks of rain or snow get in. will most likely relocate to farther up in trunk area later: (http://i790.photobucket.com/albums/yy186/GR3Y5H3ART/IMG_20150227_220411.jpg) Title: Re: Adding a 2nd Battery Post by: timot_one on February 28, 2015, 10:06:54 AM Good call on getting a battery box. As suggested before, a battery isolator is the best option when adding a second battery.
Title: Re: Adding a 2nd Battery Post by: 2i2dk1ny2i3 on March 01, 2015, 06:18:09 AM yeah, for sure need a Box for it, theres even about 1/4 of the Box left for additional storage
will look into the isolator thanks |
