New to forum: 2003 Mach1: Looking for info on exactly how to connect wire to fusebox?

Hi Everyone,

Just joined the forum today. I am adding an aftermarket amp to my 2003 Mach1. I need to connect a remote power wire for the amp. I've never connected anything to a fusebox of a car, so I have no idea how to do this. I usually find most thing pretty intuitive, but I looked under the dash and don't see any obvious place or screws to attach a wire to fusebox. Could someone point me to a thread that explains the proper way to do this? Thanks in advance for your help!

I don't know diddly about speaker amps, but I would assume that thing is going to need some serious juice to power it! Most of the fuses in the fuse box under the dash are relatively low amperage (30 or less), so I don't know if they could even handle it. The big fuses are located under the hood, driver's side fender. That's what you may have to tap into, but I'm not real sure. Maybe somebody who has done this type of thing can help you out.

First I'll say HI:hihi: and now..... the bad news....

You DON'T....... the power wire to the amp is usually 30 or more amps. What power is the amp, RMS??? What size (amperes/amps) is the fuse in the amp??? Next is where r u wanting the amp to be installed (or even better is how many feet is it from the battery). This is because the higher the power requirements (amperes) AND the length of the power wire (resistance measured in ohms), will determine the size (ie 12ga, 8 gauge, 00 ga.) of the power wire. And the "gauge" is bigger wire the smaller the number where 00 ga is like the diameter of your thumb.... but thats for 1000 watt amp 20 ft from the battery.....

ps you MUST install a 40-100 amp fuse @ the battery when you install the amp power wire... They sell kits to install amps @ most places that also sell car stereos n speakers...... It should have pictures and tell you what you need 2 know....... also try and keep your patch cords AWAY FROM the power wires n also keep the "GROUND WIRE" as short as possible.... this is to reduce the chance of getting radio noise.........

I'm assuming this amp is for a sub. 4 guage will do fine. Run that from the post of your battery throughthe firewall, under the door molding stuff and to the trunk. That's your power line so somewhere as close tv the battery as you can get put an online fuse. For the groin make it short with the lowest possible guage wire. Then your amp is powered. You just for to hook up the remote and input.

you are probably right but if he is putting a high current amp in there and the wire is too long it will overheat and potentialy melt the wire.
