Audiotek 8700DSP 1/2 Din 7 Band Car Audio Equalizer EQ Front, Rear + Sub Output, Up to 7V RMS of Output, Gold-Plated RCA connectors for Best Audio Output for Car, Boat, RV, RTV, Motorcycle

Never bought this brand in my 30 plus years in car audio. I had purchased a American Bass that was very similar but under a year of using the American Bass the tentiomiters were becoming scratchy and the frequency adjustment for the subwoofers out started to fail. So I seen this one and noticed after installation it had smoother tuning and Tiffany RCAs. Going on 7 months using it and I'm very impressed. My Alpine head unit paired with this made a big difference. Very satisfied so far. And the pre amp/ line driver is powerful. Just give it a dedicated power supply.

This thing works great. I bought one 9 years ago for my boat and it’s still going strong. I bought another just to keep as a spare. At this price why not?

Works very good,except when you turn off the music, you get a very loud High pitched sound. No other pre amp eq did that.

Working perfectly

Great for the price.

This works great. At first I had two problems not created by the pre-amp. 1)Driving it from a speaker jack without an attenuator, 2) Not knowing that the REM terminal needs to be connected to power. 1) Bought an attenuator that goes between the radio speaker output and the pre-amp. 2) Connected a wire from the + positive terminal and the REM terminal on the power plug. All is well

this acted like it was returned but never remanufactured. it had ZERO EFFECT ON ANYTHING

Ya pronto a instalacion y a disfrutar las buenas notas

Llegó en perfectas condiciones nada más no trae las bases que sostienen al equalizador
