Some facts about Car Audio


1) Your radio is absolutely the most important component in your audio system! Speakers and amplifiers can only replicate the

signal they receive; if you have an ‘average’ or factory radio, the quality of sound coming from your speakers will be greatly
compromised, especially at higher volumes. Using a radio with pre-amp outputs (RCA’s) of 4 volts or more will send a super-
clean signal to your amplifier(s) and speakers.

2) No matter what radio you have, they all produce a better signal with a higher dB when playing a CD, MP3, etc. The exact

same song played on the FM band simply won’t sound as good or ‘get as loud’ because the radio is pulling the signal in from
the radio station wave versus producing it internally.

3) If you do have an amplifier(s), you should try to make the ground wire as short as possible. The seat bolts make for good

points to attach your ground wires to the vehicle. Use a ring terminal but make sure that the terminal is coming in contact with
bare metal. You may want to scrape some paint away under the bolt for the ring terminal to rest on to ensure a great ground.
You should also run the ground wire for your radio to the exact same bolt to reduce ground loops and alternator whine (Noise
in the speakers when you hit the gas).

Centra-Pod Installation:

1) The poly-fil included in the pod should be fluffed up prior to installing the speakers for the best sound. Make sure there’s no

debris in the pod, as it could compromise sound quality.

2) Armor-All® or equivalent can help give the pod a darker black, glossy look.
3) Check placement of pod and cut a small slit in the carpet behind the pod for the wires to run up to the grommet hole located on

the rear-center of the pod.

4) You may have to cut the speaker holes larger for certain speakers if you purchased the pod empty.
5) If you’re using an amplifier, you probably know how you want to run the speakers. If you’re not, it’s suggested that you tap

into the dash speakers to run the pod. Your fader control will then adjust the dash and pod at the same time.

6) The pod speakers will be marked +/- but the dash wires can be confusing. Usually the darker wire with the stripe is the ground

wire. You can attach one of the dash speaker wires to the positive terminal on a 9 volt battery. If the speaker cone pushes
outward, you have the positive speaker wire.

7) Make sure to plug the remaining air space around the wires at the grommet hole with wax, glue gun, etc. to avoid any

‘whistling noise’ caused by allowing air to escape from inside the pod.

8) Included are two self-tapping hex screws. Using a 5/16” hex bit, run the screws through the bottom of the pod, through the

carpet and into the floor of the vehicle and then screw the speakers in place. (There are no pre-drilled holes in the base of the
pod due to individual vehicle needs/placement of the screws). One screw behind each speaker is best.
