### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Excellent line Driver EQ
  

*by D***N on Reviewed in the United States on February 8, 2023*

I've been Hifonics HFEQs in my car for many years now. I'm actually running 2 of them in my 1984 Oldsmobile Delta88 as we speak. One for my door speakers and one for my 8-12 inch sub woofer set up. Great sound quality and output. I'm running 8-8000 watt amplifiers in my trunk as well. Hands down for the price one of the best line driver EQs on the market.

    Great product
  

*by R***D on Reviewed in the United States on September 8, 2012*

When I installed a new head unit in my '02 Maxima, the preamp output voltage to my stock amp was not enough to drive the speakers very loud even at max level.  So I ordered the HFEQ from Amazon and it was promply shipped by B&E Electronics.  With the newly installed Bazooka subwoofer, all the sounds exploded from my speakers. I never knew how good my speakers sound.  And I really like the ability to change the speakers settings at my finger tips on the HFEQ and not have to go into the head units program to do so. I was fortunate that the double din fixture that fit my car easily fit the new radio and the HFEQ. So if you have line driver volt problems plus you want to have control at your finger tips, this product does it.
