What subwoofer impedance does the Stadium 600 want?

It is rated at 600W RMS into 2 ohms. A 2-ohm sub or a pair of 4-ohm subs wired in parallel suits it best. Expect less power into 4 or 8 ohms.

Can I connect it to a factory radio?

Yes. It has speaker-level inputs, so you can tap factory speaker wires without a separate line-out converter. Line-level inputs are there for aftermarket head units.

Does it come with a bass knob?

Remote bass control is listed as a feature, so a dash-mounted knob is part of the package. It lets you trim sub level without reaching for the amp.

How big is it for mounting?

About 10-7/16 inches wide, 7-1/16 inches deep and 2-3/16 inches tall, at 2.27 kg. That fits under a seat or behind a trim panel in most cars.

Can I run two subs off it?

Only if they are wired together as one 2-ohm load. It is a single-channel, non-bridgeable amp, so it cannot power two independent sub channels.

Is the Stadium 600 worth it over a bigger mono amp?

If you run one sub at 2 ohms, its 600W RMS and small size cover most setups. A larger amp only pays off if you need more power or a second sub channel.

About the JBL Stadium 600 Mono Class D Amplifier

The JBL Stadium 600 is a compact Class D mono amplifier built to drive a subwoofer. It is rated at 600W RMS into 2 ohms (1500W peak) with an active low-pass filter, remote bass control and both line-level and speaker-level inputs. Its footprint is small, about 10-7/16 by 7-1/16 inches and 2.27 kg, so it fits in tight spaces. Against rival mono sub amps it trades extra channels and preamp outputs for a simple, light single-sub design that is easy to hide.
