HI Big Bully,

The Blue wire is the remote and it couples with the Blue on the back of the Head Unit. If your head unit does not have a Blue , use the Yellow. This will Turn the amp on and off with the Head unit.

08 lancer battery keeps going dead tried 3 new batteries installed,had new belts installed as per recall,alternator checks out


Based upon what you have said, it would seem that you have something that is causing a continuous battery drain. Have you added any new electronics to the vehicle that may have accidentally been wired up to a constant hot source instead of one that is controlled by the ignition switch? Many enthusiasts accidentally install stereo amps directly to hot and find they never shut off, killing the battery. If you are skilled at electronic troubleshooting, you may be able to track down a wiring problem yourself. I will warn you that many repair shops will attempt to diagnose your problem, but few are trained to do it efficiently. If you decide to pay a pro to fix it, go to an Auto Electric specialist. They charge more per hour, but will take far fewer hours to locate and repair the problem than the corner mechanic.

How can i make my lighter live all the time 2008 toyota solara


This is kind of involved - you'd probably be better off to get a 12v lighter ( accessory ) socket assembly from your local parts house with a 30 amp inline fuse and wire it directly to your battery. Many of these accessory kits come with a mounting bracket so you can mount it somewhere convenient. Don't wire one directly to the battery without a fuse as you could cause a major meltdown and / or fire. Getting a kit rated 30 amp will be more than enough current for your needs.You could run a new wire ( 14 ga. Minimum) to your existing socket through a fuseholder then to the battery but, usually, it's difficult to get access to the lighter socket to hook up the wire. If you do this, make sure you use a quick connector and don't just wrap the wire on the terminal end - it could fall off and cause a short circuit which may kill ( and burn ) your car.
Hope this helps!

A 96 GC should have a regular belt driven fan. 16 ga wires are not big enough to power any type of fan motor, Are you sure they are not 14ga?. If the factory fan broke, just replace it. Try hooking the wires directly to the battery, make sure it spins the right direction, if not, reverse the wires but make sure the fan is on the right way, you may need to flip it over. The fan should be hooked to a thermostat, you dont need the fan spinning 100% of the time.

The fuse in the red wire that connects to the battery blows everytime i connect the negative and positive up 2 my battery. it blows when i dont even have the red chord hooked up 2 the amp. whats the...


Hello super11dt,

Sounds like the power and ground wire are shorting. Check the power wire with a multimeter. Sometimes, the insulation gets rubbed off and it contacts the vehicle metal causing a short. The solution is to pull a new wire and install a grommet or bushing wherever it goes through the firewall.

Actually, the negative (ground) wire should not be run to the battery at all. It should be secured to the metal of the vehicle as close to the amp as you can get, preferably within about 3 feet.

Hope this helps.

I NEED DIRECTIONS ON HOW TO CONNECT MY AMP TO MY CAR


We'll start with powering the system up. YOu will need to run your power wire from the battery. It must have a fuse just after the battery. Run the negative to the chassis of the vehicle. On the back of the radio, there will be a blue wire labeled remote/antenna. This wire needs to be connected to the amp. This is what turns it on and off when you power up the radio. Next you will need to run the RCA cables from the back of the radio to the amp. Now you are ready to hook up the sub woofers to the output side of the amp.

Yes, watch out for bad wiring! My father's 73 chevy caprice caught fire because of an amp that was wired in poorly. If you have a multimeter it shouldn't be too hard to find each speaker wire, as the speaker will show up with a certain impedance, Like 4 ohms of 8 ohms. Wiring it in phase is the real trick. For that you can only hope there is some sort of color code that the car came with, and there is a pretty good chance there is. I am assuming you are looking at the chopped radio wiring harness. There might be something like brown with a white stripe, and white with a brown stripe. It could also just be brown, and brown with a white stripe. You get the idea. They should all be wired in the same pattern, If they did not do this, then the some car manufactures just have better standards. I believe you can take a AAA battery and hit the two wires you know to be one speaker, and you should hear a pop from that speaker. I would be careful doing that if the speakers are really old, but it should be safe even then.  
Its amazing what a 15 dollar multimeter can do in everyday electronics. My friend and I built an electric motorcycle, and obviously its very crucial for that, but I have used it for tons of things besides that. Especially old car wiring.

Blowing fuses


Are you sure you don't have the positive and negative power wires reversed?

Does the fuse blow without remote voltage applied?
