AUDIOTEK8700DSP 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

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?

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

Not bad it's better than my mustang stock eq a lot more control very sharp and crispy on the highs but you got to be careful with the super Bass and the Low on it or else you might blow out your door speakers especially if you're on a amplified setup this thing runs dirt cheap I can imagine what a high quality one would sound like or I can't complain it's getting the job done but I definitely would recommend it as a entry level starter kit or even something a little bit more advanced such as I got myself

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.

Best bang for your buck. The audio went from mediocre loud sound to absolute perfection on the Bass Boom Bottom frequencies. A big plus is that it's got Tiffany's RCA plugs. That's usually for high end stereo equipment. This is one happy customer.

Solid EQ. Never wired one before and there's no instructions but basically you use your Head Unit's Front OR Rear L&R connections as inputs on this thing, which then feeds to your 4channel amp. You won't want to go back once you have one.

I have had many eq Graphic and my perferd Parametric .Like this unit that work great in all aspects .I have been on the hunt and sent back 5 diffrent ones a few costing 3x more as this one .You cant go wrong with this eq.Gives nice clean frequency boosts and trims .Up date this is my 2nd Audiotek 8700DSP eq the first one had a broken part inside floating around .Now the 2nd one cuts off all three output signels and the meter display. Once ran for about 20 mins .Turing it off and on gives you 30 sec and cuts off the sound again .Only it resting on off will give you another 30 mins.I am going to give it one more replacement incase its just bad luck .

its nice i like it its good it works real good
