I have my grounds secure. My amp wired correctly, yet my my amp will blow the fuse that is in the 12 volt wire running from my battery to the amp. I wasted 20 fuses all of witch was 20-30 (size). The amp I have is 1600 watts, and recently I had a sony explode (250 Watt amp) hook up and it served no problem. Is there any certain procedures i need to take to avoid this? Should I just hook 12 gauge wire with no fuse directly to the amp?
The wire from your battery is blowing fuses? and you are using 20-30 A fuses? mine has a 100A fuse..look into getting new wire plus my wire is 4 gauge.., 1600 watts is too powerful for a 12 g wire and a 30 A fuse

Re: car amp blows 12 volt wire fuse
A power wire with no fuse will set the car on fire if the wire shorts to ground or if the amplifier draws too much current through it.
A 12g wire is too small for a 1600 watt amplifier.
If the amplifier only blows the fuse after the remote voltage is applied (after the head unit is switched on - volume at minimum setting), the amplifier likely has shorted output transistors and will need to be repaired.

It could have to do with how your speakers are wired. If you have 2- 4 ohm speakers and they
are both wired to one terminal (RIGHT OR LEFT) on the amp, you have a 2 ohm load and most amps are rated at 4 ohms.

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.
Go over all your wiring. Make sure your power wire isn't grounded somewhere. If your power wire is touching any bare metal it will spark and blow the fuse the second you touch the power to your amp. Make sure your in-line fuse is about a foot from your battery, and make sure you have your ground wire grounded securely to the main chassis of the car/truck and that it is either same size gauge as your power or even a little bit bigger gauge. Also make sure no strands of wire from your ground or power wire are loose and reaching over touching the other where you plug them into the amp. If the ground and power touch eachother they will blow the fuse and possibly cause permanent damage to the amp.
Check the amp turn-on wire. It's a blue/white wire running from the radio to the amp. It's probably label REM at the amp. This wire sends a switched 12 volts from the radio to the amp. It is probably shorting out somewhere between the radio and the amp.
well this is what you do to check it to see if you bought a blown amp.
wire it into your car and then take a digital volt meter check to see if you have power and ground and remote turn on .
take the red lead and put it on the battery wire at amp and the black lead to the ground then see if you get 12volt to 14.4 use the amps ground for the black test lead if nothing you may have blown fuse or bad ground.
check the remote wire same way as about if you get 12 to 14.4 volt it works if not could be blown from radio or bad ground
checking the ground put the black meter lead on ground wire and the red lead on 12 volt power source if nothing a bad ground.
if your get voltage on the remote wire and battery wire and have good ground then you need to call the seller and get your money back ..
Check the fuse sometimes when hooking them up youll blow a fuse.but make sure your ground is to bare metal no paint should be on it. very important.. also make sure the blue wire has current using a light tester or volt meter. if you have a long wire run it directly from battery to see if its the remote wire . sounds like a bad ground is the amp new what is the brand
Here are the troubleshooting steps for fuses blowing.
1) Remove all wiring except ground, power and remote and see if the amp powers up without blowing the fuses. If it does, the problem is in the input cables or speaker wiring.
2) The use of loudspeaker impedances below the recommended minimums will cause the amp to draw excessive current - check.
3) A shorted or grounded RCA cable may cause the fuses to blow - check. 4) If an amplifier fuse blows continually, with only +12 volt, ground and remote leads connected, the amplifier is probably defective, most likely shorted output MOSFET's. In this case the amp needs professional repair or replacement.
very simple run a ground from gnd on amp to a good ground spot on car run 12 volt power cable from back of fuse relay by battery to 12v+ on amp then splice blue wire on back of stereo splice in another wire about seven feet run that to remote on amp then hook up speakers its pretty simple to hook up an amp hope this helps
