Need Help Fast!!! Trouble Wiring Subs

[GT98]

everything is all ready to go except the hot wire lead. I was told to hook a wire up to an accessory fuse in the fuse box under the dash. How do I wire something into the fuse box? I need help bad

The hot lead should be hooked directly to the battery with a fuse under the hood. When I installed stereos I always liked installing a breaker under the hood. The are a little more coin than the screw in fuses but never have to be replaced. Also make sure your ground is good, your remote line is hooked up to the right wire, and most of all make sure you have the right gauge wire.

well just take a wire striper & cut a few inches back on the wire & wrap it around the end of the appropriate fuse. then your done, execpt for where you decide to run the wire i took off the plastic molding on the inside if the door seal & ran mine under there on my first car. it looked very clean that way

If you hook it directly to the battery then wouldn't it be on all the time? I'm still kinda confused.

There's four wires that get attached to an amp.

1) Signal wire, RCA style usually coming from the head unit or a line converter.
2)A good solid chassis ground. Very important, bad ground will cause a whistle in your speakers and your amp to overheat. Heat is bad.
3)A constant 12 volt power source fused at source. The amp line should be hooked to the battery due the imense draw of power. There should be a fuse mounted within 2 feet of the battery for safety reasons. The line should be run INSIDE the car with a grommet around any sharp metal. Not in the door jam or under the car. The guage should be right for the amount of power. Usually 8 gauge is good for any one amp set up using amps you can buy at a best buy or circuit city.
4) A remote line. Amplifiers have a on/off switch built in. The remote line is run to a switched source on your radio like a power antenna line or all aftermarket head units have a designated line for that. The amp should only be on when the radio is on. The line doesn't have to be thick it can be just a thin wire.

Any questions?

Thanks a lot for the breakdown. That did help a lot. I do have a question though. For the remote line. Where do I tap that into? Like where is the wire located, what does it look like, etc. I get nervous doing electrical stuff so I just wanna be certain. Oh and I also have the Mach460 with the stock headunit.

the remote or switch wire will go into the "remote" or "switch" wire on your deck (red on pioneer decks and most others, should be labled). also make sure you run the RCA from yuor deck completely opposite the main power wire to the battery, badfeedback will occur if you don't.

edit: depending on your deck, you might have a wire made specifically for an amp switch, use that if you have it so not to butt connect 3 wires

If you can get your hands on a test light you can pull the remote right off the back deck. The Mach has 2 amps on the back deck. Pull the harness off of one, attach the test light to a good ground, and then have a buddy turn the radio on and off while you touche each wire. When you find the one that turns on and off with the radio splice it and attach your remote line to that. By splice I meen piggy back the remote line to the harness making sure the factory harness is still intact. Plug it back into the factory amp and you're ready to go. You can also pull your rca's from the low signal wire. When you drop your back seat the wire and harness are up top attached to the amp rack. There's ony one wire harness you can't miss it. Let me know how it sounds.

Actually most aftermarket headunits use a blue wire for remote. Red is acc, yellow is constant, black is ground.

Since you are using your stock deck, it won't have a remote turn on lead. You will need to hook the remote lead from the amp to a switched source. Meaning one that has power with the ignition on, but not when the ignition is off.

Thanks for all of your input guys. I got the lead hooked up and the amps running but im getting no sound. My dad thinks its cuz I wired the it up to the system wrong under the rear deck. I got the info off Mustangworld and did exactly what it said to do to wire it into the system. Why am I getting no sound now?

If your getting power to the amp(Remote line is turning the amp on, good ground, power hooked up) and still no sound, then it's signal. Check where your grabbing the actuall signal from.

Yeah everything is hooked up and I'm getting power to the amp but I'm still getting no sound. I tapped into the wires under the deck that were green with black stripes and black with white stripes. Just like it said to do on the Mustangworld How-To page. Whats missing?

 

[GT98]

Everythings running great. But i still have a problem lol. The subs hit really hard and clean, but thats pretty much it. i'm guessing thats due to the box (under seat compartment) not being completely sealed. Would that be it? Any input would be great. Thanks a lot
