Review: So far it’s working for my application. - I did a mild, budget friendly upgrade to the system in my 04 Expedition Eddie Bauer. Rockville media player, four 6x8’s and reused my SS8P under seat sub. I got full range from the factory sub, amp and crossover in the back. I saw a few bad reviews on this and was skeptical, so I ordered this, a pair of $40 FMod 150hz low pass filters and a $20 Nippon HC-101 to try. I thought this would help with running the FMods as active, being how they are run through RCA female in to male out. I figured it might help with finding the lows and also turn my RCA connections back around again. The Nippon didn’t work as an active crossover. Possibly not enough from the preamps to power through, or it just wasn’t designed for that. Still waiting in the FMods. I thought I’d go ahead and connect this and I think this did the trick for $15. Back to nice deep bass. Gonna send the other two items back for a refund.
Review: Great product, worth the buy! In and out was just mislabeled for the opposite sides. - Works as it should. I rather use this than the gain control that comes with the amplifier. Plus you can turn your frequency high on your amp and just use this. Only thing the in and out were mixed up. They must have printed it on the wrong side. Just make sure you check one side of the other if you don't have sound.

## Questions & Answers

**Q: Im trying to use this on a car audio system, will this filter out the higher frequencies like vocals? Im getting the same sound from sub and speakers.**
A: No it's just a gain control meaning you just control the volume of the bass up or down

**Q: Where does it plug in can i use it on a home stereo reciever to make it a sub amp**
A: Plugs in inline on rca cable. Yes works on home or car, any rca line system.

**Q: Can you get this as a high pass unit ? I understand how it works I'm in need of this exact same thing in high pass 12db slope**
A: As I said to another person the Rolls SX45 has both a low and high pass function being a two way crossover. Cost is $99.

**Q: can this be used as a low pass filter?**
A: It is indeed designed to be a low-pass filter. The frequency range is adjustable, allowing you to tune out high and mid range frequencies to blend your sub(s) in as they should be, in a well balanced set-up. It actually works very well. I've tested 150 (clean and real) Watts through two of them with no problems, for my sub system.

### ⭐ READ BEFORE YOU BUY.
*by S***I on December 28, 2020*

Despite this product stating and appearing that it controls frequency; IT DOES NOT. So, for those looking to this for it’s claimed crossover capability as I did; BEWARE. I ran test tones and sweeps. (I did not go any higher than 250hz) It’s not even a 120hz simple filter... It let all frequency through. This box is simply volume control; so back to Amazon it goes.
