Massive Audio EQ9 – 9 Car Equalizer with 9 Band Graphic Equalizer - Aux Inputs - 7V RCA Outputs - 18dB Crossover

I decided to give it a try after previously owning a massive product, and I'm glad I did. This eq brings out the best in my amp's sound. This is connected to my LG V20, which has a quad dac, and the sound is very clear and crisp. br>br>Recent changes: br>br> 15th of May, 2020 I recently installed this EQ in my 2019 Honda Ridgeline, and the instructions were a little confusing and unclear because I was trying to use the factory stereo's high-level inputs. However, I spliced together an old pair of RCA wires and connected them to the factory stereo speaker output as well as the EQ. The EQ auto turns on when the factory stereo speaker outputs turn on without using the remote, but every time it did, it made a loud pop through my speakers. I was able to eliminate the popping when turning on by connecting the remote turn on wire, which allowed the EQ to turn on with enough lead time before the speaker input signal arrived. I still recommend this EQ because of the great sound it produces. It has low-level and high-level speaker inputs, making it a very versatile EQ.

I may be a little ahead of the curve, but I received this eq today and decided to install it (2015 Chevy Cruze). When I plugged it in, it lit up but there was no sound. I checked my wiring and it was all correct, so I couldn't figure out what was wrong. It turns out the aux button was pressed and I had nothing hooked up there, which is why there was no sound. I only say this in the hopes that anyone who orders this and does the same thing doesn't get The lights seem a little on the "why is this so bright" side but I have this hooked up in my glove box so when it's closed you can't see it (to help deter thief) I would fully recommend this unit it's a good price it's a bit heavy am made of metal and not a cheap plastic the only negative things I could say about this unit are 1. 2. the lighting is excessively bright Instead of a built-in fuse, it includes an online fuse. The lights are blue and orange, not blue and red, as advertised. I wish there was an off button for the lights on the switch, but none of these are deal breakers. As for the line driver, I can't confirm or deny that at this time because I haven't tested the output voltage with the unit before; with the stock head unit, it was only 1. I'll update this review once I've tested it with the eq.

I'm not sure what these people are talking about when they say it's a bad EQ; I believe it's more a case of not knowing how to hook it up (engine whine) and not getting enough bass (wrong deck setting). My first one is still in use, but my buddy was so impressed with my setup that he asked me to get him one. It has increased by $30 since January. Most things that aren't worth anything won't be worth anything by 2020. I will say that at full volume on the EQ side, it will distort, so turn it down to 8 instead of 10. I have all of my EQ values set to mid line, volume at 8, sub at 10, and fader set to mid. My deck controls the majority of the settings, and I also run one pair of RCA's to the EQ main and set the deck as a REAR/REAR for RCA's rather than REAR/SUB or SUB/SUB for RCA's, which works great. The knobs are small, but they stay in place once you've set them. Overall, you can't go wrong with this as long as you're not a newbie who doesn't know what they're doing. The boosted line drive is required when you've got two 1000w 4channel amps and one 1300w 4channel amp running 4-channel. 6x9's, 4- 2in x 5in 12in subs, 4 6x8/5x7's on the deck, and my 20-year-old car has no trouble powering this setup.

Everything appears to be in order. It looks like a clarion, but it doesn't have the same sound quality or volume. I replaced my clarion because of intermittent shorts, and mine was much clearer and louder. I don't believe the line drive is as good as they claim, but you get what you pay for.

really, really bad Look elsewhere if you're looking for a deep, satisfying bass. I purchased it to replace an aging Chinese knockoff known as Boschmann (as shown in the attached photos), but I am dissatisfied. My old cheap Chinese one has much better deep bass than this one, which is a real shame. I've tried switching inputs (both power and signal), but nothing seems to work. The mids are deserving of two stars. They're quite decent. Unfortunately, that does not meet my requirements because this equalizer drastically underutilizes my subs. Go for it if bass quality isn't an issue for you. AVOID it if you don't know what you're doing. It was a complete waste of money.

I installed this eq and must say, I'm very impressed with it. I have 4 6. 5 points for being in the middle. a subwoofer and a tweeter box with six tweeters It has a lot of clarity to it, which I like. I used to have a powerful Austic equalizer, but it only lasted a month. Let's see if this equalizer can last me a long time.

Unfortunately, this unit only added to the noise in my system, and the engine noise is louder than the actual radio signal when the engine is running. I double-checked my grounding and messed around with it for a while, but even a ground loop isolator couldn't help. I made the decision to get rid of this device.
