![]() It's adhered with PL400 construction adhesive, so it's never going to come apart. I very carefully cut out a section of it and shortened it by about 8.5" or so. I didn't want the foam to look like a hack job, and I still wanted a little storage bin, but I also needed an amp rack. I'm putting the amp in the hatch under the trunk mat in the lower right hand corner. ![]() It's 6.85" x 7.09", so it's a little bigger than the RF amp, but it will fit where I need it. ![]() That's only $33 more than the more popular Rockford Fosgate PBR300X2, but this is class D and pushes 2x as much power at 2Ω. ![]() I got the amp online through Car Audio Dealers on Amazon for $202. The amp will push 300W RMS 2Ω, so it should be a perfect match for the RLP254, since it can be wired for 2Ω. Will replace with the pioneer.įor the amp, I wanted a good quality compact (roughly 7"x7" or less) class D subwoofer amp, of which there are very few to choose from. My MB Quart also just blew out yesterday. The OP finally replaced it with the Pioneer SW-2501 and said it sounds at least as good as the MB Quart. See the thread here: Two blown MB Quart subs. It also specifies an internal box volume of exactly what the UBER-STEALTH under the floor box is, so that works out well.ĮDIT : Regarding the sub, there have been some people who have blown theirs. I got it off Amazon for $71, and I'm hoping it sounds great, because it's hard to find any real reviews. I'm adding this sub to my Dynaudio system, and I'll document all of the wires I tap and where/how I run everything.įor the sub I'll be using the MB Quart RLP254. #Rockford fosgate pbr300x2 popping noise install#I'm starting the thread now, because I know Nik sold at least 20 sub boxes during his sale, so there are probably some people out there looking for install ideas. I ordered it just 2 days ago, so I'm getting everything ready by mounting the amp and running wires. Dimensions (HxWxL): 1.53 x 4.25 x 6.75 (in.), 3.90 x 10.8 x 17.I hope you didn't come here looking for instant gratification, because you won't see the sub box actually get installed for probably 2-3 weeks.Average Current Draw (13.8V Music): 23 A.Visual Indicators: Power/Protect, BRT (Boost).One minute it's working and the next minute it's not, usually with the green power LED on the amp turning to red or orange. One of the more confusing car stereo problems can be when an amplifier goes into protection mode. Remote Controls: Optional PEQ provides 0dB to +18dB at 45Hz Amplifier Protection Mode Troubleshooting.Speaker Output Connector: 4-Pin Harness.Power Input Connector: Detachable Compression Terminal.Hi-Level Sensitivity: Variable DC offset sensitivity.Signal Input: High/Low Level Input: 4-Pin harness.Tone Controls: Optional Remote Punch EQ.Crossover Controls: High-Pass: 50Hz - 500Hz at 12dB/Octave Butterworth, Low-Pass: 50Hz - 500Hz at 12dB/Octave Butterworth.Total Harmonic Distortion (THD+Noise): 4-Ohm: less than 1.0 percent, 2-Ohm: less than 1.0 percent.Efficiency (average): 68 percent at 4-Ohm.Frequency Response: 20Hz - 20kHz +/-3dB.Dynamic Power (PVC/PowerCube): 114 Watts x 2 at 4-Ohm, 160 Watts x 2 at 2-Ohm, 387 Watts x 1 at 4-Ohm Bridged.Total Power (Sum of Rated Power): 300 Watts.Rated Power (RMS Continuous Power): 100 Watts x 2 at 4-Ohm, 150 Watts x 2 at 2-Ohm, 300 Watts x 1 at 4-Ohm Bridged.CEA-2006 Compliant: CEA-2006 Power Rating, 100W x 2 at 4 ohms, less than or equal to 1.0 percent THD+N.Variable 4-6 volt hi level DC offset voltage input turn-on control.It is great for smaller stealth installations, as well as for motorcycles and recreational vehicles. The BRT also has a variable hi-level DC offset turn-on circuit for easy installation into any OEM system. This allows the chassis design to be much smaller than traditional sized amplifiers. The Punch PBR300X2 uses our patented BRT (Boosted Rail Technology) for an ultra efficient design that does not use a switching power supply to generate its rated power. This amp is great for smaller stealth installations, motorcycles and recreational vehicles. The PBR300X2 is a 300 Watt amplifier with Boosted Rail Technology, allowing it to be compact and efficient while providing big power.
