A: It can power up to 4 speakers simultaneously — one per channel. You can also bridge channels 1+2 and 3+4 to run 2 subwoofers or larger speakers at 1000W each.Q: What gauge wire do I need to install this amp? A: The power terminals accept 4-gauge wire, which is what we recommend for installation. Speaker terminals use 12-gauge wire.Q: Is this amp compatible with my factory head unit? A: Yes — it features both High and Low Level Inputs, so it works with factory head units (no RCA output needed) as well as aftermarket receivers.Q: What's the minimum impedance this amp is stable at? A: The GP-2000.4 is stable down to 2 Ohms per channel in stereo mode and 4 Ohms when bridged.Q: Does it have built-in protection? A: Yes — it includes both overload protection and speaker short circuit protection to keep your system safe.Q: Will this amp overheat? A: Crunch built in Quick Thermal Dispersion Heat Sink technology to actively manage heat. As long as it has adequate airflow during installation, overheating is not an issue under normal use.Q: What's in the box? A: The amplifier unit. Mounting hardware and RCA cables are typically sold separately — we recommend picking those up if you don't already have them.SHIPPING & RETURNSBrand new in original manufacturer packaging.
