Frequently Asked Questions - THA 485 BLAUPUNKT

What is the RMS power rating of the Blaupunkt THA 485?

The RMS power handling is 50 watts per speaker, providing clear and distortion-free sound at moderate volumes.

Will these speakers fit in my car?

The THA 485 is a 6.5-inch coaxial speaker (16.5 cm) with a mounting depth of 2.5 inches. Check your vehicle's speaker cutout size and depth to ensure compatibility.

Do the speakers come with mounting hardware?

Yes, they include mounting screws, brackets, and wire connectors for straightforward installation.

What impedance do these speakers have?

The impedance is 4 ohms, which is standard for most car audio systems and aftermarket head units.

How do I install the Blaupunkt THA 485 speakers?

First, disconnect the car battery. Remove the door panel or speaker grille. Disconnect the old speaker and connect the new one with correct polarity (positive to positive, negative to negative). Secure the speaker with screws and reattach the panel.

Can I use these speakers without an external amplifier?

Yes, they are designed to work with head unit power (up to 50W RMS). For higher volume and better clarity, an external amplifier is recommended.

What type of music do these speakers perform best with?

The THA 485 offers a balanced sound signature suitable for rock, pop, and jazz. The silk dome tweeter provides smooth highs, while the polypropylene cone delivers clear mids and bass.

How do I clean the speakers?

Use a soft, dry cloth to gently wipe the cone and grille. Avoid liquids or harsh chemicals, as they may damage the speaker materials.

Are these speakers waterproof?

No, they are not waterproof. They are intended for interior car use and should be protected from direct exposure to water or moisture.

What should I do if the speakers stop working?

Check the wiring connections and fuse first. If the issue persists, contact Blaupunkt customer support or an authorized service center for warranty or repair options.

System Planning

Prepar system planning is the best way in minimize your amplifier's performance. By planning your installation carefully, you can avoid shortages where the performance and reliability of your system is compromised. Our authorized inside has been trained to maximize your system's sound quality when installing the amplifier, and is a valuable resource in helping you with your system's design and installation.

Speaker Requirements

Each channel of your amplifier can easily handle 20x a speaker loads when used in Stereo Mode. When a channel pair is bridged, the recommended minimum load impedance is 42 for subcooler use or full range operation. Although operation with lower impedances is not likely to cause immediate damage to the internal circuitry, the unit will most likely overheat, causing the thermal protection circuitry to shut down the amplifier. When the chassis code down, normal operation will resume.

Continuing to operate the amplifier under these conditions is not recommended and will reduce its life expectancy. Most speakers designed for the audio operation are 40 experience. Connecting two such speakers in parallel will result in a 20 nominal impedance, which is not recommended for use with bridged channels of your amplifier.

Symptom
Possible Cause

Poor bass response	Speakers rated wrong priority causing cancellation at low frequencies	Check speaker polarity & change as needed
	Crossover set incorrectly	Reset crossover referring to the multi-cross crossover configuration section of this manual for detailed instructions
Battery fuse blowing	Impedance load to amplifier too low	Check speaker impedance load if below 20 stereo or 40 mano, retire speakers to achieve a higher importance
	Short in power wire or incorrect power connections	Check power and ground connections and repair as needed
	I use used is lower than recommended rating	Replace with proper fuse rating
	Too much current being drawn	Check speaker impedance load if below 20 stereo or 40 mano, retire speakers to achieve a higher importance and replace with recommended fuse size
	Short in power wire or incorrect wire	Check power and ground connection and repair as needed

Amplifier fuse blowing

Too much current being drawn
Check speaker impedance load. If below 2

stereo or 4 mono, rewire speakers to achieve a higher impedance and replace with recommended fuse size

Check power and ground connections. Repair as needed
Fuse used is lower than recommended rating
Replace with proper fuse rating

Trouble Shooting

Symptom	Possible Cause	Action to take
No output	Low or no remote turn-on input	Check remote turn-on voltage output on amplifier and correct as needed
	Fuse blown	Check power wire integrity and reverse polarity, repair as needed and replace fuse
	Power wires not connected	Check power wire connections and repair/replace as needed
	Audio input not connected or no output from source	Check input connections and signal integrity repair/replace as needed
	Speaker wires not connected	Check speaker wires and repair/replace as needed
Audio cycles on and off	Speakers are blown	Check system with known working speaker and repair/replace speakers as needed
	Thermal protection engages when amplifier heat sink temperature exceeds 80°C	Make sure there is proper ventilation for amplifier and improve ventilation as needed
	Loose or poor audio input	Check input connections and repair/replace as needed
Distorted output	Amplifier level sensitivity set too high, exceeding maximum output capability of amplifier	Reset gain. Refer to the tuning section of the manual for detailed instructions
	Impedance load to amplifier too low	Check speaker impedance load, if below 20 steren or 41 mors, revise speaker to achieve a higher impedance
	Shorted speaker wires	Check speaker wire connections and repair/replace as needed
	Speaker incorrectly connected to amplifier	Check speaker wiring and repair/replace as needed. Refer to the installation section of this manual for detailed instructions
	Speakers are blown	Check system with known working speaker and repair/replace as needed

BATTERY

Notes on the power supply Connect the 12V power input lead only after all other loads have been connected.
- Be sure to connect the ground void of the unit security to a - In case correction may cause a malfunction of the amplitude
• REMOTE: The unit is turned on by applying + 12Volts to this terminal. This terminal does not draw heavy current
Like the two power terminal so a tinner connecting wire is acceptable. Standard 18 GAUGE is fine and the standard colour is blue. If the radio is equipped with a power antenna control wire, it can drive this terminal. If the power antenna wire is already in use, you can still splice into it. With this method, the unit will turn on automatically with the radio.
• Use the power supply lead with a fuse attached whose value is the same as original fuse.
- Place the fuse in the power supply lead as close as possible to the car battery.
- During a full power operation, Maximum current will run through the system. - Therefore, Make sure that the leads to be connected to the +12v and GND terminals of the unit respectively must be larger than 10 Gauge (AWG, 10).
