The Orbital Sander – For Smooth Surfaces

The orbital sander is one of the most popular cordless sanding tools when it comes to preparing large surfaces for car audio installations. Its oscillating movements ensure smooth surfaces, which is indispensable when cutting amplifier plates or preparing paintable covers for the trunk.

• Oscillation rate: Typically between 6,000 and 11,000 rpm.
• Sandpaper size: Mostly in the 92×182 mm range for precise sanding of large MDF surfaces.
• Battery compatibility: Models from Makita (e.g., LXT 18V) or Einhell (Power X-Change) make handling easier.

The Orbital Sander – For the Extra Touch

Those who want as few visible sanding marks as possible rely on the random orbital sander. Its rotating and simultaneously oscillating movements ensure a fine grain and provide precise results when preparing surfaces for new car audio installations.

• Rotation speed: Often around 4,000 to 12,000 rpm
• Eccentric stroke: Depending on the model, 2.0 to 5.0 mm
• Application area: Perfect for smoothing contours on custom-fit car speaker grilles

This allows even curves on doorboards or custom fiberglass enclosures to be easily prepared. Those seeking maximum control will find a variety of options in the cordless segment, such as Makita XGT (40V) for heavy-duty tasks or Einhell 18V solutions for smaller projects.

The Belt Sander – For the Tough Jobs

When installing an elaborate car audio stage in the trunk, for example for multiple amplifiers and additional capacitors, a belt sander is often the ideal tool. Its endlessly circulating sanding belt quickly removes excess material and rapidly creates smooth surfaces.

• Belt speed: Usually between 200 and 400 m/min
• Band length: Typical dimensions such as 533×75 mm or 610×100 mm
• Suitable for: Rough removal on massive MDF carriers or thick cladding panels in car audio installation

Faster material removal means less time lost on large projects before making further fine adjustments with random orbital or multi-sanders. With the right battery capacities (e.g., 5 Ah or 6 Ah), even extensive tasks can be completed in one go.

The Multi-Sander – The Flexible All-Rounder

The multi-sander makes work on angled vehicle areas easier for you. You can use it to modify the dashboard, make delicate adjustments to doors, or perform polishing work on small surfaces.

• Sanding sheet shape: Often triangular or rectangular
• Vibration frequency: Between 7,000 and 10,000 oscillations per minute
• Application area: Whether wood, metal, or plastic – effortlessly for doorboards, amplifier mounts, or brackets

To work precisely in hard-to-reach areas inside the vehicle, a battery-powered model with low weight is worthwhile, so that long-term projects on your SEAT or Opel can be carried out steadily. Plug&Play accessories like hook-and-loop sanding sheets save time-consuming conversions.

The Detail Sander – Perfection in the Corner

The detail sander is a specialist when it comes to sanding tight angles cleanly in the footwell or on the rear door panels. Especially with custom car audio installations featuring unusual shapes, this lightweight sanding tool shows its strengths.

• Conical grinding tip: Ideal for reaching angled areas
• Triangle plate: For precise grinding movements on hard-to-reach edges
• Contact pressure: Precisely controllable for gentle work on sensitive surfaces

Whether working on speaker grille inserts or small wooden parts, the delta sander brings precision to every corner.

The Angle Grinder – The Powerful Problem Solver

When it comes to customizing metal components for amplifier mounts or performing bodywork, the angle grinder is recommended. It can not only cut but also grind and roughen.

• Disc diameter: Common sizes are 115 mm or 125 mm
• Idle speed: Average 8,500 to 11,000 rpm
• Suitability: Correction of auxiliary frames, cutting metal rods for subwoofer mounts

Especially in the car audio sector, an angle grinder can be useful if you want to work with metal constructions. For projects demanding maximum power and endurance, there are options with Makita XGT 40V that tackle challenges in no time.

Batteries of the new generation

With the latest battery series, countless application options are open to you for your car audio upgrade. Whether you just want to quickly smooth screw connections or plan a complete system upgrade, having enough capacity saves you from constant recharging.

• CXT 12V max.: Compact Batteries for Flexibility in Door Installation
• LXT 14.4V and 18V: High capacity, perfect for multi-hour audio component adjustments
• XGT 40V max.: Extremely powerful performance, suitable for quickly sanding thick MDF boards for subwoofer mounts
