HifonicsHFEQ Multiple Source Signal Processor (Black) – 4-Band Equalizer, .5 Inch DIN, 2 Audio Inputs, 9 Volt Line-Driver, Master Volume Control, Subwoofer Control, Dual Amp Fader

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.

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.

I love this thing it added auido quality 2 my music now i dont have 2 turn my phone all the way up i dont use a headunit because why they are useless and add alot of emi if ur just useing a aux imput and u can switch the imputs so if i ever did use my headunit i could i dont like that it gets hot a little at half volume and whenever i try 2 charge something through the car it causes a ground loop and it makes tones of interfearance to run through the music

This device is awesome it gave me all the outlets I needed to complete my stereo car system although the bass doesn't sound good when u hook up the sub output so I just run it straight from the head unit to the amp input then amp output to the devices input and it sounds amazing

Excellent sound and build quality. Internal board is well laid out with decent components. The pots are all sealed and have a good feel to them especially the volume and sub control. Red and blue lighting that isn’t blinding. Clean sound with no floor level sound seeping through. The filters are excellent, use the EQ filters and set your amplifier filters off.

This product gives your sound system the perfect touch for tuning the sound quality to your liking

Extremely dissatisfied with this product it does not distribute the front and rear level correctly at all yes it has two channels but it takes front and rear in one channel and the secondary Channel please at a separate time not simultaneously

This thing really pumps out the low frequencies. It gave me the lows I was looking for. Bass you can hear as well as feel rumble through all your organs haha. 45hz and also boosts the line level to 9 clean volts. I would definitely recommend.

Excelente
