    Do you have the GND or Earth connected? And is it a clean connection?

  • greglm6914 Mar 19, 2011

    Yes ground wire connected. First we ground it to the bolts on the bottom of the driver seat. It came on for a little then off. Then we connected it to the negative battery terminal and it worked for a min then right back off. Somebody help please

Too much current (amps) being drawn ..and is dropping the voltage.

Usually due to a failing battery.

Does it maintain the 12v or more with the engine running?

    Yes it maintains 12.5 to 13.8 when the truck is running

Jumped starter terminals 30/87, starter works but no crank when key turned on.


Click no start is typically a bad battery, bad starter, bad solenoid or loose dirty battery connections. But seems you have covered those items. Have you checked you negative battery cable where it attaches to the frame and motor? Use multi meter and check from positive of battery to the motor(block) for 12 volts. Also do this while turning key to start position. If voltage drops out when doing this double check battery voltage and all connections. If it does not drop then check the solenoid wire coming from ignition. When key in start position you should have a good twelve volts. If you you do then test the main leads hooked to solenoid for power. If solenoid wire from ignition has less than 12 volts double check connections at battery and also test the clutch pedal switch.

How to connect wires to amp


Most amps have 3 places where you need to hook up wires to power them. the 1st is a ground wire that at best is 1 foot long and it goes on the ground or negative 12 volt connection then a bolt on the car you may need to sand off the paint for it to work, 2 a RMT or remote wire that is normally in the middle of the power and the ground connections the remote turns the amp on and off so it needs to go to the remote wire on the radio or a ignition spot on the fuse box - turns on with key on and off when you turn the key off , 3 the power wire is hopefully large 4 gauge wire and goes to the + 12 volt plug on the amp this wire has a in line fuse and goes to the battery and to the amp only. RCA wires go from the radio to the amp and are round and just plug in with no screws some factory radios need a conversion kit you can get at walmart for RCA wires. the speaker wires have some sort of mark or line to tell you what to put were like if you put the line on a negative on the amp you need to put the line on the negative on the speaker box to or it will not bass and could hurt your amp. ask me if you need anything else :) and please rate :/

Fused 12 volt power wire from the battery connects to +12V at the amp. Chassis ground wire connects to gnd at the amp. Switched 12 volt power wire (accessory) (remote turn on from after market radio) connects to rmt at the amp.

Starter stay engaged after it starts


If your starter stays engaged after the vehicle starts with the remote starter then, the vehicle's starter wire is receiving 12 volts, most likely from the remote starter's ignition or accessory wires. Check the connections to the vehicle's wiring: the battery wire is constant 12 volts, regardless of key position. The accessory wire(s) is 12 volts with the key at accessory and on/run (position 1 & 2), the ignition wire(s) is 12 volts with the key at on/run and start (position 2&3), and the starter wire(s) is 12 volts with the key in the start position (position 3) ONLY. Make sure that the remote starter wires are connected to vehicle's wires as directed by the Bulldog instructions.

I am tryin to install a sony xplode amp and subwoofer in my car to the stock stereo but i dont know what wire to splice into for the rem on my amp


for a remote turn on you can use the acc off of the ing ( test 12volt when car is on befor crank goes to 0 during crank then comes back to 12 voltswhen car is running 12 volts also goes to 0 when ing is turned off and key is in off positon. 12 volts from the battery fused 12 inches from connection and ground. also are you using some sortof high level adapter for an audio signal( this would tap into left and right spks either front or rears and provde you with rcas for your amp

Amplifier will not come on and when i hook the amplifier up the the radio comes on without the car being on


did you check to see if your remote wire for the amp as connected to the ignition wire thats the most common mistake. the ignition wire is the one to tell the radio and amp when to turn on and off it sounds like you have it hooked up to a constant 12 volt which is the battery wire. the ignition wire is the one that is 12 volts only when the car is turned on.

I need to know how to wire the power cables and other wires to the amp and then to the subwoofer plz can you help me nath


hey dennis if you have a standard car amplifier all you need to do is run a wire from the battery post straight from the battery to amp batt+ post, then negative side can also be run straight from battery negative, than the remote post on your amp. you can either utilize the power antenae circuit coming out of the stereo unit or an ignition power from your ignition power fuse box so you don't draw battery power when key is off, please reply back if your stereo unit has rca output and does your amp. have rca connection(rca connections are red and white audio cable style connection).

Remote wire?????


The old pioneer car radios solved this problem by supplying the battery power to the radio from the amp. When the radio turned on, it began to draw more power from the amp supply lead and this would turn the amp on. It was a simple circuit in the amp that only used one or two transistors. You may need to build this circuit or find a manufacturer of a similiar circuit. In the short run, you can use a small toggle switch to supply the trigger voltage (+12 volts) to the trigger wire connection on the amp. Good luck.
