Your Car Audio Store for Subwoofers, Amps, Batteries and Everything In Between

Showtime Electronics is a car audio shop built by people who actually compete. We stock the gear that survives being pushed — not entry-level filler — and most of it ships in 1–2 days.

Subwoofers and enclosures. From 6.5" up through 18"+, plus ported and sealed subwoofer enclosures ready to drop in. If you're chasing a number on the meter, this is where you start.

Amplifiers. Monoblock through 6-channel, from daily-driver power to full competition burp amps. Down4Sound, Sundown, Ampere Audio, Incriminator and more.

Speakers and head units. Pro audio speakers and midranges, components, coaxials and tweeters, plus single DIN and double DIN radios with Apple CarPlay and Android Auto.

Batteries, alternators and wire. XS Power AGM, lithium and SuperBANK cells, high-output alternators and brackets, and OFC and CCA power, ground and speaker wire in every gauge from 8 AWG to 00.

Car audio accessories. Bass knobs, SMD install tools, fuse holders, lugs, battery terminals, RCA cables, distribution blocks and splitters.

We carry Sundown Audio, XS Power, Kicker, Down4Sound, Incriminator Audio, Wet Sounds, SMD, Full Tilt Audio, Turbostart, Resilient Sounds, Stereo Integrity, Orion, PRV Audio, DC Audio and more than 60 other brands.

Car Audio Questions We Get a Lot

Do you offer free shipping?

Yes. Orders over $99 ship free within the continental US. Most in-stock items leave the warehouse in 1–2 business days.

Which XS Power battery is right for my system?

It depends on your total amplifier power, your charging system, and whether you're daily driving or competing. Our battery technology guide walks through AGM, lithium and SuperBANK, or call us at 865-334-7828.

Is everything covered under manufacturer warranty?

Yes. We're an authorized dealer for every brand we carry, so your gear ships with full manufacturer warranty and is eligible for easy returns.

Can I negotiate on price?

On eligible items, yes. Look for the Make an Offer button on subwoofers, amplifiers, batteries and alternators, send us your number, and our team comes back with our best deal.
