Punch PBR300X1 Heartbeat Issue
Chuck C., Crutchfield
23 November 2015
Summary: Great amp...when it works. Small and lots of clean power, but I've learned that the "heartbeat" problem I'm experiencing is a common one. When the amp is turned on, it does not produce program audio, only a continuous 1Hz thump of the speaker.
Summary: It came out of the box rated from RF testing at 308 watts, that was nice. I have it pushing the RF P3S 12 Punch sub enclosure in my 2006 GMC sierra quadcab. THe sub is taking everything this amp gives it. The combo is working perfectly though. It sounds amazing! The sub hits hard with this amp.
Conclusion: Ran it in an 2010 Honda Ridgeline. Replaced factory radio with double din and installed the amp behind the stereo. Powers factory sub great. An easy fix/upgrade when needing to run factory sub with aftermarket radio.
Conclusion: I was planning on using only one Rockford punch amp in my Saturn Sky project. But after hooking everything up in the basement and seeing how well the Punch PBR 300x1 drove my sub-woofer. I decided to replace the new Kenwood amp I purchase with a second RockFord Punch PBR 300x2.
Conclusion: Okay, so get over the "That's what she said"-ish title, this amp fears no man! It is the size of my palm for crying out loud! The RF PBR300X1 is a fantastic amp for your system. Being that it is 1 ohm stable producing 300 watts RMS (my amp birthing sheet gave it a 327 RMS!
Conclusion: This amplifier has been fantastic. So much clean POWER from such a small package. Easy to mount, easy to hide, it's just a great piece of audio engineering. I would HIGHLY recommend this amplifier to anyone in need of a very solid amp, in a very small package.
Conclusion: I really like this amp alot. I have two of these in my car running two 2011 P3 12s. (One to each sub wired at 1ohm). These slam! I custom built a box to spec for the subs and no-one believes me that they are taking only 300 watts RMS each. People cant believe the power these little guys can push.
Summary: Hooked this thing up configured to a 1-ohm load and wow, runs pretty stable at 300W even when driving for hours. Fits nicely behind my rear seats of the DC tacoma. The sub I have the newer Rockford Fosgate P2D2-10.
