Review: Award winning soundstream well atleast there processors - This product works great . If you have alternator whine or anything like it this product will make it more pronounced so know that going in . This is absolutely great for the price soundstream is known for winning all sort of awards for there processor and crossovers I have been very surprised by there stuff so far I am 25 yes in car audio I run about 8000rms system hdx12 s sound qubed and 8000.1 vulcan stetsom the subs and amp both have surprised me with how great they are the stetsom is a beast and you must have a ho alt and battery bank to keep up with it but well worth the investment if you want to shake cars 10 ahead of yours buy this crossover and a stetsom amp wowwwww!!!!!!!!
Review: Brings audio to life! - I spent $2k on a Pioneer HU/Amps and Cerwin Vega speakers. It sounded "hollow/tinny". I added this to separate all of the freqs. Can still use the HU to make adjustments instead of going to the PROX4.1. So, if you have separated highs, mids, and lows, this is HIGHLY recommended.

### ⭐⭐⭐ Looks cool but idk
*by J***S on December 4, 2021*

Blue light is really bright. Idk but the buttons seem a little janky off an on mono stereo. Bass boost. Think one side not working properly on the low rear speaker. Still trying to figure it out.
