    • These work
Size: Protect 3.5" Speaker
They work great. I updated the speakers and factory radio in my truck. The dash 3.5’s sounded terrible and were distorted with bass. These took about 10/15 minutes to wire in and eliminate all bass from my dash speakers. It’s sounds so much better

    • MUST buy for clean, distortion free 3.5” upgrades!
Size: Protect 3.5" Speaker
So…I upgraded to new JBL Club 3.5” dash speakers in my OEM 2018 Chrysler 300 stereo. Chrysler’s built in EQ settings and crossovers on the UConnect basically prevent the volume from getting loud to protect their cheap speakers (mine is a non-amplified system). If you have a newer model 300, you know that the overall factory soundstage is pretty good, it just lacks those crisp highs and volume to really jam out. If you do upgrade to the JBL Club 3.5” speakers, I would HIGHLY suggest that you order these Recoil BB-35 Bass Blockers to install on the positive speaker wire of the speakers. The signal coming from the factory head unit to the dash speakers is a full range signal (highs, mids, and lows). The JBL’s come with a resistor installed that run to the tweeter to protect it from the lower frequencies, but nothing to filter the signal to the actual 3.5”. Initially I had to turn down the bass on my EQ so low to make the new JBL’s sound clean, and distortion free, that I lost that mid-bass that I enjoyed so much from the 6x9’s in my front doors and rear deck. The Recoil BB-35 bass blockers filtered all of those unwanted signals from playing through my new JBL 3.5” dash speakers so that I could turn up the low frequencies on the EQ giving me the upgraded soundstage and louder volume I was looking for. I couldn’t be happier from such an easy and cheap upgrade to my OEM system! ... show more

    • Perfect Little Bass Blockers for 3.5" Dash Speakers
Size: Protect 3.5" Speaker
I installed these RECOIL BB-35 bass blockers inline on my new Kicker 3.5" speakers, and they do exactly what I needed them to do. In my setup, the 3.5" dash speakers are installed in parallel with 6.5" Kickers on the same channel of the amp. These bass blockers help keep the low-end bass out of the smaller dash speakers, which lets the 6.5" speakers hit a little harder in the mid-bass while the 3.5" speakers handle the cleaner highs like they should. The result is a better-balanced sound with less distortion from the dash speakers, especially when turning the volume up. They are well made, compact, and easy to install. The wiring was straightforward, and they were small enough to tuck away in my 2023 Jeep JL dash without making the install messy. For the price, these are hard to beat. Great product at a great price, and they worked exactly as expected. ... show more

    • Awesome for Dodge Journey!
Size: Protect 3.5" Speaker
I recently replaced all 6 speakers in my 2015 Dodge Journey with MTX Terminator speakers and I noticed that it sounded awfully distorted and the 3.5” speakers on the dash were playing low frequencies which they are NOT supposed to do, and that really scared me thinking that it would blow them. I did some research and another person wrote a review on these about how these capacitors changed the whole sound system on their Ram and blocked out the low frequencies from their dash speakers, so I decided to give these a try and see if it would make a difference. After splicing up the Metra harness and wiring these capacitors up, it changed the WHOLE SYSTEM! The door speakers AND dash speakers all sound loud AND clear! No more worrying about the dash speakers blowing, and it even gave the door speakers more bass. 100% would recommend these if you own a Chrysler/Dodge/Jeep/Ram, these little things solve your problem! ... show more
