Auto Style Guttaman（as-g.jp）is a car audio specialist shop located in Shizuoka, Japan. Its website is mainly used to showcase services, installation workflows, speaker packages, display audio solutions, new products, and installation case studies. It is closer to a localized professional installation provider than a traditional e-commerce platform.
The site focuses on “スピーカープラン” speaker plans, “ディスプレイオーディオ” display audio external input adaptation, and “デッドニング” soundproofing / vibration damping work. The process is fairly complete: customers first inquire by phone or email, then visit the shop to discuss their needs. The shop proposes a plan and quote, and after confirmation the customer pays for the products. Once the products arrive, the vehicle is scheduled for installation, followed by a handover explanation after completion.
The disclosed budget for speaker plans is 60,000–70,000 yen. This includes selectable speakers, inner baffle kits, dedicated accessories, front-door installation, basic soundproofing, soundstage tuning, speaker cable replacement, and labor fees. Some product prices are listed, such as KICKER CSS674 at 32,000 yen and TRUIM APK 165P at 42,000 yen, while some Pioneer models are shown as open-price items. Payment methods include cash and various credit cards.
The main advantage is that the service chain is clear, and the packages combine products, accessories, and installation work, making choices easier for ordinary car owners. In addition, customers who purchase and install car audio products at the shop receive free sound-quality adjustments for life with no limit on the number of sessions, which adds meaningful after-sales value. The drawbacks are that it has weak online e-commerce functionality, with no visible shopping cart, online ordering, delivery, return, or exchange information. Pricing transparency is limited, final costs still depend on an in-store quote, and the service is clearly constrained by location.
It is suitable for car owners in and around Shizuoka who want to improve in-car sound quality, upgrade speakers, add external input options for display audio systems, or install door soundproofing. It is not suitable for sellers looking for cross-border purchasing, online wholesale, or multi-vendor e-commerce transactions.
