We built Alpine Auto Supply because we were tired of overpriced parts, confusing options, and brands that talk a big game but don't deliver when it matters.

Every product we carry is something we'd run on our own vehicles. Period. We focus on quality aftermarket parts, proven tools, and trusted automotive products that help you build, maintain, and upgrade your ride the right way.

Taramps has been building high-efficiency Class D amplifiers in Brazil for decades, and their price-to-watt ratio is unmatched. We stock the models we'd actually install — from the compact TS 400x4 to the 5000W MD 5000.1 — in the USA, so you get the real thing with fast shipping and a warranty that's honored.

• Free shipping on every order, shipped from the USA the same business day before 5pm EST.
• 30-day returns on unused items and a 1-year manufacturer warranty.
• Honest answers. Send us your speaker or sub specs and we'll tell you what fits — even if it means a cheaper amp.
