Getting into car audio can feel overwhelming with all the terminology, brands, and options out there. This thread is here to help!
**Common Questions:**
**Q: What size subwoofer should I get?**
A: It depends on your goals! A single 10" or 12" is great for adding bass to your daily driver. If you want to feel it in your chest, look at 15"s or multiple subs. Competition builds? Sky's the limit.
**Q: How much power do I need?**
A: Match your amp to your subwoofer(s). Check the RMS rating on your subs and get an amp that delivers that power at the correct impedance. More power isn't always better if your electrical can't handle it.
**Q: Do I need to upgrade my electrical?**
A: If you're running more than about 1000W RMS, you should start thinking about a bigger alternator and additional batteries. Headlight dimming is a sign you're maxing out your electrical.
**Q: Box design - ported or sealed?**
A: Sealed boxes are smaller and give tighter, more accurate bass. Ported boxes are louder and more efficient but need more space. For SPL competition, ported (or 4th order) is the way to go.
**Q: What brands are good?**
A: There are tons of great brands at every price point. Sundown, American Bass, DC Audio, Down4Sound, Sky High, Skar, Taramps, Crescendo - all make quality gear. Buy from authorized dealers!
