Before installing the equipment on the car, dismantle all seats, because they will interfere, there is a risk of damage to the seat upholstery.
Remove the front door trim and rear parcel shelf.
Lay the acoustic wiring on the floor of the passenger compartment, lead the wires to the places where the wires will go into the front doors and to the middle of the rear shelf. Leave a little headroom so you can connect your speakers without adding wires.
Using self-tapping screws, screw the speaker amplifier under one of the seats to the floor of the car and connect the speaker wiring to it. Also connect the signal wires and connect them to the radio. Find a free opening in the firewall and use a steel wire to run the positive supply cable under the hood. Use a powerful fuse to connect it to the positive side of the battery.
Use a damp cloth to clean the interior cavities of the front doors. When the water is dry, use a cloth soaked in solvent to degrease the areas where you will stick the soundproofing sheets. Without this measure, installing powerful speakers is useless. half of the speaker's power will not turn into sound volume, but into the rattling of metal doors.
Examine the lower front corner of one of the front doors. Mark with a marker where you can make a cutout for the speaker. The cutout should be as low as possible and close to the front edge of the door. Measure the obtained distances from the bottom and front edges of the door and, in accordance with the obtained values, make a marking on the door trim. Use a jigsaw to cut a hole for the speaker in the casing. Seating templates are usually attached to the speakers.
Attach the door trim to the door and trace the hole in the trim on the metal with a marker. Using metal scissors, cut a hole for the speaker along the resulting contour.
In the area where the speaker will be located, glue the previously prepared soundproofing sheets. Glue the sound insulation on the outer sheet of metal from the inside as well.
Run the acoustic wire through the door. Replace the door trim, pull out the speaker wire and connect it to the speaker, observing the polarity. Install the speaker in the made seat, fix it with metal screws.
Repeat steps 5-9 for the second door.
Using a jigsaw, cut out a new rear shelf trim from a 16mm thick chipboard sheet. It is better to install oval speakers in the rear shelf, because they have increased bass response. Place the speakers on it so that they do not touch the torsion bars that support the trunk. After cutting the holes for the speakers, put the new rear shelf in place and trace the holes on the metal with a marker. Cut holes in the metal using your metal scissors.
Cover the new rear shelf with Carpet, then install it in place, pull the shelf to the body with self-tapping screws. Carpet is well glued with Moment glue. Install the speakers in the shelf, fix them with self-tapping screws and connect the speaker wires to them, observing the polarity.
Place back in the seat.
Adjust the volume of the amplifier, if necessary, turn on the low-pass filter for the front speakers, adjust the bass boost for the rear speakers according to their capabilities.
