As this noise forces you to turn the volume up, you'll quickly find that your in-dash radio's small amplifier runs out of steam. The amp wiring kit establishes an independent power source for an aftermarket amplifier or powered subwoofer. Cut a length of power wire that can reach without tension from the battery terminal to the amplifier's mounting location. Insert the other end of the short lead and the stripped end of the long lead into opposite ends of the fuse holder. Cut two lengths of speaker wire sufficient to reach the amp from the back of the radio. Purchase a fuse to snap into your inline fuse holder matching this value.
Vehicle owners who wish to boost the signal strength of their car's factory stereo system or add an aftermarket powered subwoofer will first need to connect an amplifier wiring kit. You'll use this for the power wire. Locate a mounting spot for the amplifier away from foot traffic and seat rails and providing at least 3 inches of space around the unit for ventilation. Slide these into the slots at the base of the T-taps. Examine the internal fuse values of the amplifier. Now i did not yet do this in my car yet as of i don't have my license so i why put it in the car if i can't hear it? Locate a section of sheet metal within 18 inches of the amplifier's mounting location.
Slide the other end of the long lead through the grommet protecting the wire bundle you identified during your preparatory steps. Turn the amplifier gain all the way down. The kit will also connect the signal and turn-on lead cables via patch cables from the head unit to the amplifier. Reinstall the radio into the cavity, reversing the steps taken to remove the unit. Secure these wires by tightening the Allen screws inside the holder over the wire strands.
Consult your car's wiring schematic to locate the screws holding the radio into the dash bezel. Screw the ring terminal to the bare sheet metal using a Philips self-tapping screw. For additional information, see the Global Shipping Program This amount includes applicable customs duties, taxes, brokerage and other fees. Remove the nut holding on the red positive lead, but do not remove the wire from the battery. Have you ever ran a dual amp setup? Screw the amp to the intended mounting location. For additional information, see the Global Shipping Program New: A brand-new, unused, unopened, undamaged item in its original packaging where packaging is applicable. You can have a professional car audio technician install your Scosche amplifier wiring kit, or you can save time and money by doing it yourself.
As a financial sales consultant, Pamplin produced sales copy for two of the largest banks in the United States. Wiring tools include a socket wrench and inserts, combination wire stripper and crimper, self-tapping sheet-metal screws, cordless drill with Philips-bit attachment and rough-grit sandpaper. Crimp a ring terminal to one end of this wire. Packaging should be the same as what is found in a retail store, unless the item is handmade or was packaged by the manufacturer in non-retail packaging, such as an unprinted box or plastic bag. This is how I've got the amps in my cars hooked up I own 5 vehicles which all have systems, 3 of them have dual amps. I have never ran both amps at the same time, and wiring for 2ohm, 4ohm, bridging and whatnot is starting to get a little confusing when it comes to wiring it right.
Also, if you still want to incorporate a switch to turn the amp on and off, incase of the cops being around and you've got noise ordnances and don't want to be worried that if you leave it turned on and drain your car's battery, you run the remote wire as in the correct set up from the amp's remote to the head unit's remote wire but cut the wire where you want the switch at install the switch there. The remote turn-on wire can be even thinner, and it only needs to be long enough to reach your head unit from wherever you have chosen to locate your power amp. I'm just waiting to go to the store now to get a wire kit and a new radio because mine sucks, then ill hopefully post a pictures. Screw the speaker wires into the amplifier terminals, matching the polarity observed at the radio. There are many factors that work against quality car audio. In this instructable I will show you how to wire your amp and an alternate way to wire your amp. Locate a wire bundle under the hood that leads from the engine bay into the cabin of the car, and find where it comes out under the dash.
My way is pretty much exactly the same. The first three connections are necessary in order to provide power to your new. Pull the power wire through carefully. Turn the amplifier gain up to the point where audible distortion is heard, then slowly reduce the gain until it disappears. Secure the under-hood fuse holder to an existing wire bundle using a pair of 4-inch zip ties.
The biggest culprit is road noise, competing with and canceling out critical audio frequencies. Screw the power, ground and remote wires to their respective terminals on the amplifier. Do not use a seat belt bolt or a welded location for the ground, since these do not provide proper continuity and may cause ground-loop whine or amplifier malfunction. Remove these screws and set them aside in a cup holder or a zip-top baggie. Strip 1 inch of outer insulation from each end of the wire. Cut a smaller length less than 18 inches long.
Carefully pull the radio from the dash. See the seller's listing for full details. Before removing even one screw or panel from the vehicle, assemble all of the tools and parts you'll need for the project. Cut a length of ground wire 18 inches or less. It should be pointed out, that if you forget to turn the switch off, the amp still has power and can drain the car battery if left on for a long period of time overnight if you sleep 8+ hours or a short period if your battery's on it's last leg.
When the car's head unit is off, the power to the amp is off. Crimp a ring terminal to one end of the short lead. This fuse protects the power wire leading through the vehicle, preventing a fire in case of a short circuit. Slide the ring over the post holding the positive battery lead, and secure the nut holding the leads in place. Snip off the excess with the tips of the wire strippers.
