FAQ – Pyramid PB717X Amplifier
Can I bridge the PB717X to run a subwoofer?
Yes. The PB717X is a 2-channel bridgeable amplifier. Bridging combines both channels to power a single subwoofer. Always follow the amp’s manual for the correct bridged terminals and impedance limits.
What impedance is safe when bridged?
The amp is 2-ohm stable in stereo. When bridged, most 2-channel amps require a higher load (typically 4 ohms). Check the manual and wire your sub accordingly to avoid overheating or protection mode.
What size power wire should I use?
Use quality OFC cable sized to your run length and power needs. Many installs use 8 AWG for moderate power; step up to 4 AWG for longer runs or subwoofer duty. Always use an inline fuse within 12–18 inches of the battery.
Does it work with factory head units?
Yes. The PB717X accepts both high-level (speaker) and low-level (RCA) inputs, so you can integrate with stock or aftermarket head units without additional converters.
How do I set the built-in crossovers?
Use low-pass (LPF) when powering a subwoofer and high-pass (HPF) for mids/tweeters or door speakers. Start with a typical 80–100 Hz crossover point, then fine-tune by ear to your system and enclosure.
What fuse size should I use?
Match the fuse to your wiring and current draw. Many wiring kits include an appropriate ANL/AGU fuse; verify against the amp’s manual specifications and never exceed the wire’s ampacity.
Where should I mount the amplifier?
Mount on a solid surface with good airflow—under a seat, on an amp rack, or trunk side panel. Avoid carpeted enclosures without ventilation and keep clearance around the heat sink for cooling.
Why does the amp go into protection?
Common causes are low speaker impedance, shorted wiring, poor ground, or clipping from incorrect gain. Re-check wiring polarity, verify load impedance, and set gains with the head unit at a moderate volume.
Can I power door speakers and a sub at the same time?
The PB717X is a 2-channel amp. You can run stereo speakers (HPF) or bridge it for a single sub (LPF). To power both simultaneously, add a second amplifier or use a 4-channel plus a dedicated sub amp.
Is the PB717X covered by a warranty?
Yes. Pyramid includes a 1-year warranty. Keep your proof of purchase and follow installation best practices to remain covered.
