- Can it power four speakers and a subwoofer at once?
- Yes. It has five channels: four for front and rear speakers and one for a subwoofer. That makes it a one-amp solution for a full system.
- Can I bridge the channels for more power?
- Yes, the main channels are bridgeable. Bridging pairs two channels into one stronger channel, which suits a component set or a small sub.
- Is it stable at 2 ohms?
- The main channels are rated for 2-ohm loads. Check the subwoofer channel's rating before wiring a low-impedance sub.
- Can I use it in a boat?
- No. JBL does not rate this amp for marine use, so it belongs in a car or other dry, enclosed space.
- Does it have a built-in crossover?
- Yes. It has adjustable crossover, bass and phase controls, so you can tune speaker and sub channels without extra processors.
- How much space does it need?
- It is about 14 inches wide and 7 inches deep, so plan a flat mounting spot with airflow, since it runs warm.
