I bought the Monster Bass Combo for my 2025 Jeep Gladiator. It's worth every penny. BRP has done all the work of designing the perfect system for bass that doesn't require permanent modification of my Jeep. I've had a Rockford Fosgate system in my vehicles since 1989. These 10s hit as hard or harder than my 12-inch P3s. I've always used RF amps, but after installing the Audiocontrol amps, I'm now a fan. I even bought the Audiocontrol 800-watt amp for my mids and highs. I'm super pleased with this purchase and performance of this system. And Robert, the owner of BRP, is super helpful if you have any questions. He doesn't just respond to emails and texts, but phone calls as well. I installed my amps on a 1/2-inch plastic board. It sits behind the rear passenger seat and locks in place. There's enough slack in the wires where I can set the board on the seat, or outside the jeep, for wiring and adjustments. I've also changed out the 3.5" and 4.5" speakers in the rollbar to 6.5" speakers. I chose the Pioneer speakers TS-Z65F (2-Way, 110 watts RMS, 330 watts peak). I also used the Metra JP-1019 Jeep Soundbar Speaker Adapter Kit to add the 6.5" speakers. And I changed the 3.5" dash speakers to Pioneer 3.5" TS-A879 (100 watts RMS, 450 watts peak). I chose not to replace the knee speakers at this time. My 2025 Gladiator has less than 3K miles and I don't want to tear the dash apart at this time. And I don't think it's necessary. My last truck I had 13 speakers and three amps. My Gladiator has 6 speakers (not counting the unamplified knee speakers) and two amps and is just as loud or louder with better sound quality. read more
