Tools and material needed	Routing wires

Tools:

ŠFlat and Phillips screwdrivers

ŠWire cutter

ŠWire stripper

ŠElectric drill with drills

ŠCrimping tool

ŠDigital multimeter or test lamp

ŠWire brush, scraper or a piece of an abrasive sheet to remove

paint for a good ground connection

ŠGrease to protect the ground connection from oxidation

Material:

ŠSpeaker wire: minimum

12 AWG = 4 mm2 for subwoofers

13 – 16 AWG = 1,5-2,5 mm2 for other speakers

ŠSheet metal screws for mounting the amplifier to the amplifier board and the amplifier board to the car + some extra for fuse holder, amplifier ground etc.

ŠElectrical insulation tape

Š½ inch thick plywood or particle board for the amplifier to be mounted upon.

Amplifier installation kit:

If available,buy an amplifier installation kit. It contains normally all you need. This is what you have to buy if you buy the items separately

Š2025 feet = 6- 7.5 meter power cable, preferably AWG 8 = 10 mm2 or heavier

Š1 pc of fuseholder to install close to the car battery + fuse 50 Ampere.

Š20 feet of AWG 15 = 1,5 mm2 wire for remote turn on / off cable from radio.

ŠRCA-cable for input from radio.

- 20 feet or 5 meter for trunk installations -12 feet or 2 – 3 meter for under seat installations

ŠTwo min. 8 gauge ring crimp terminals –one for connection to the battery plus and one for the amplifier ground connection.

ŠTwo heavy fork crimp terminals to connect + and – to amplifer – but you do only need them if you use heavy cable or to make the installation look nicer.

ŠFour to eight fork crimp terminals to connect the speaker cables – but you do only need them if you use heavy cables or want the installation to look nicer.

ŠOne fork crimp terminal to connect the remote wire to the amplifier, but you need only to make it look nicer.

ŠFour to eight splicers to connect speaker cables to high level input cable, if high level input is used.

ŠWire ties

ŠInsulating grommet or insulating tube

Stereo head unit

Professional Tip:

If amplifier installation kits are available with different size of power cable, chose the most heavy power cable to improve sound quality and to allow more amplifiers to be installed now or later.

If possible buy AWG 4 = PL 21 mm2 (or heavier) cable for best performance.
