Re: when i hook up the remote wire it makes my power wire...
If the battery is strong enough to start the engine, you probably have a bad connection or a defective fuse in the power wiring. If you solve the voltage problem and the amp blows fuses, it likely has shorted output transistors.
a 6ya Technician can help you resolve that issue over the phone in a minute or two.

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 :/
If it is a new radio first make sure your power wire is actually hot. Use a multi meter. Also you may have a blown fuse in the fuse panel. Check that. Make sure it is grounded as well. Improper ground will make it not power on as well. For this radio Blue = Remote that you run to your amp or power antenna. Insulate it if you are not using either. Black is Ground. Red = Your accessory wire and should only get 12 volts when the key is turned on (switched 12 volt source.) Yellow is your continuous power source. Hook this to your battery or other suitable continuous 12 volt power source. It also has a 5 amp fuse inline. Make sure it did not blow. Replace it to be absolutely sure. Use another 5 amp fuse. Never go higher. The other wires are for speaker hook up. If you do all this and still no power. You may have a faulty radio. Good luck.
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.
12 volt accessory or same wire that goes to red wire on stereo or cigarette lighter.
What is the current draw on amplified aerial ? or are you talking bout electric aerial(up and down automatically ?) If current draw is really low like 500 milliamp or so then hook her up to blue wire (remote output) on back of stereo but REMEMBER this is LOW current and only meant to switch on amps and raise electric aerials etc.If you think amp on aerial is too much for it then run the rem wire to a 12 volt relay and wire it so that when rem triggers and closes the gate will be connecting an accessory wire OR perm 12v wire to aerial power . That way aerial ONLY turns on(POWERS UP) when stereo is on as opposed to other way where aerial will be powered up every time car ign or acc is turned on regardless of whether the stereo is on or not.
Make sure this high powered amp is not mounted directly to the chassis of the car. Mount it to a wooden board and you can screw board into the car. Because some very high powered amps can arc and damage itself.
Next make sure the tubular fuse in the hood is not bad it may look good but internally it got real hot and caused a bad solder connect in the fuse. You can test it with a meter. Measure one side then the other side if the 12 volt is going thru the fuse.
Next step is now you know your amp is getting 12 volts from the car battery but do you know if your amp turn on signal is turning on the amp itself. This is a easy test get a little wire and jump the 12 volt to the amp turn on wire if the amp comes on then you have found your problem. The amp turn on voltage is too weak were ever youve connected the signal. Normally you hook it up to the blue/white wire on the back of the radio first. If it doesnt have one hook up to the blue. Now on some very rare occassions the voltage drops when you put a load to it and is not enough to turn on your amp you can easily see this if the voltage across the blue wire goes below 12volts so hook it up to the red ignition wire so at least when you turn on your radio the red will send 12 volts to the amp to turn it on and will not drop in voltage. You see that wire has to be 12volts when it drops the amp will not turn on. Same with the battery Voltage you have to maintain 12 Volts or higher for the amp to operate.
Check your ground. Make sure you sand off any paint where you grounded the amp. Also did you hook up the remote wire? It's the blue wire on the back of your headunit. Some say remote wire, others say power antenna either one will work. Sounds like one of the two...hope this helps.
75% of the time all you need to do is reground the ground wire. If you don't have a sturdy ground it can't complete the circuit. Make sure to grind off the paint so you're grounding to bare metal. Also, make sure your ground wire is the same gauge as the power wire or larger than. That should do it.
The yellow wire goes to + (hot) 12 volt constant, red wire goes to ignition switch, Hook up your amp together with the red wire
(switched) and the amp will come on with the ignition switch.
Blue and white wire is for the power antenna.
