Default Setting up my JL system

I recently installed my sound system on my new ride and want to get the amp settings dialed in.
What should my amp settings be at?
I am running 3 pairs of the JL 770's through the jl M600-6 which is being controlled through a fusion sonic hub.
Everything is wired correctly and I have not made any mods to the amp settings whatsoever since it came out of the box. The system sounds killer but it needs some tweaking and I think it should have more thump.
any suggestions on the settings would be much appreciated.

Get a sub. The 7s are loud but don't have low end bass.

take a look in the owners manual, it list expected voltage targets for each channel based on whether a channel is bridged or not. You will need a Digital voltage meter (DVM) that can read AC voltage and a test CD from JL audio or any test CD that has a pink Noise track will do ( You can download pink noise and burn it to a disk).

If you have the equipment you can also use an RTA Real time Analyzer (they are expense) to tune your system as most generate their own pink noise.

Take a look at the tutorial on Jl audio's website for specific details.

You can adjust the bass setting on the head unit but it will just distort when turned up. Imo those 7s are so loud u need a sub for every pair of speakers.

as my JL system stands right now the sound is super crisp for sure. I just think there should be a bit more loudnesss and I like to tweak the highs and lows. distortion is not acceptable. sub and mono amp will have to wait until next year. bank is busted after ripping and stripping every wire and component then pimping the new ride.

The problem ur encountering is called quality speakers powered correctly. Its happens when u do things right. I've been on boats that crank and hurt ur ears and its because its terribly set up and the speakers are distorting. Even with my system your ears don't hurt because its clean sound.

Most people are not used to hearing music on a clean system.

I am
That's why I went with JL again.
I just think with the power I am running through the speakers I should have a volume level of 11 or 12. Right now it is an 8 or 9.
With where I have the speakers mounted (cavernous leaning post and super console) the bass response is pretty good. The front of the boat's sound is fine with the mounting by the anchor locker.

download a 1khz frequency off the internet and put it on a cd. Disconnect your speaker wires going into the amp and play the frequency at 3/4 volume. You obviously wont hear it because your speakers will be dissconnected. Use a Digital multimeter and measure ac voltage out of each channel outputs where the wires usually go in. I believe speakers not bridged on that amp should be at 17.4 AC volts but you should check with jl to make sure. Adjust the settings until somewhere close to that number. Do this to each set of channels. When I installed mine I needed a little "tweaking" and by doing it this way you reduce your chances of causing damage to the speakers from too much power. Good luck and enjoy the quality sound.

I just "drunk proofed" my system:

turn the amp gain down at lowest
turn up volume of head unit all the way
turn up amp to the maximum highest you ever want it.

now your drunk buddy can't blow the speakers...

Well its time to add the subs.... too much of everything is just enough!
So with that being said.
3 pairs of JL 770's through the jl M600-6
Do I go with the 1 10" sub and 1 M600/1
or 2 10" subs and bridge the 600/1?

that amp is 600/1 at 2 ohms and 14.4v if you run 1 speaker its at 4 ohms and 300 i think. mono block amps only have one output side so the resistance just decreases as you add more speakers. with that being said id just assume do two since you have the power.

I built my first ground-up stereo last year. As a novice I found this to be one of the best articles that explains the basics and how tune your amp; written for the layman.

This whole site is a wealth of information on marine stereo installs.
