Is 2500 watts RMS or peak?

It is a peak rating. Expect substantially lower continuous (RMS) power per channel, so match speakers to the RMS figures rather than the headline number.

Can it run four speakers and a subwoofer at once?

Yes. Four full-range channels drive front and rear speakers, and the fifth channel is dedicated to a subwoofer, with crossovers on board for each.

Does it include a bass remote?

Yes. An HFR-31 wired bass remote is included, so you can adjust subwoofer level from the driver's seat.

How big is it for installation?

The chassis measures about 17.88 by 7 by 3.5 inches, so check clearance under a seat or in a cargo panel before mounting.

What connections does it use?

It has nickel-plated RCA inputs and angled terminals for power, ground and speaker wiring, which helps in tight spaces.

Do I need an external crossover or DSP?

Not for basic setups. The on-board Accu-Cross crossovers handle channel filtering, though a DSP adds finer tuning if you want time alignment and EQ.
