loudness/eq?

[BumpinTypeR 10+ year member]

Hey guys,

I set my gain on my alpine mrp-m500 amp with my loudness off, eq on flat, bass boosters on the HU/amp both off, HPF on 125hz, LPF at 100hz, and SRC-LV adjust at 4. I am running a single 12" alpine type r sub.

So my question is, can i safely turn on the super bass eq and loudness when listening to music? It makes the subs alot louder. I am asking this because i have always heard not to use the bass boosters, but wasnt sure about those other settings.

thanks

Yes. Now that you have correctly set your gains, now you are set to use your boost (or cut) to adjust to taste, music and system need.

As a general rule, you use the loudness boost (bass and trebble boost) at low volumes, and turn it off for high volumes.

It's best to use the controls on your head unit and leave the amp settings alone.

If you set with everything off turning it on will **** up your readings //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif

He's done with readings. Now it's time for listening.

Adjust to taste.

Quite possible.

Because your input voltage, will likely change with Loud on.

Don't use loud. It's a waste. it's the same as using bass boost on the amp. No bueno, just makes the subs sound crappy.

If it isn't loud enough without LOUD on, you need more moofer.

alright well i may just use the super bass eq instead of loudness...is that ok to use?

and lets see if somone understands this. I first set my gain awhile ago (2 weeks) with my loudness off, eq on flat, bass boosters on the HU/amp both off, HPF on 125hz, LPF at 100hz, and SRC-LV adjust at 0. I was shooting for 31.62 volts on the DMM b/c im running 500RMS at 2ohm....anyways when the process was done, my gain knob was set about 3/4 up (at the 0.5 marker on my alpine amp). It sounded good but i kinda had to turn my bass down some so it wouldnt drown out the music. Half way on the gain knob it says "nominal", and i was quite a bit further than that. SO...i reset my gain again doing the same process BUT this time i set the gain with my SRC-LV adjust setting at 4 (all the way up) i did this because it made my music louder (like the actual music not the bass). anyways, this time my gain knob reached the 31.6 volts right at the nominal marker, or slightly past it. Now i have a better mixture of bass/music, but i wanna be able to safely crank the bass at times, and with this new gain setting the bass was not as loud as before.

So what could i do to get more bass? Should i reset the gain where i had it before? This was when i set teh gain with my SRC-LV at 0. I dont even know what this setting is...but i knda liked the way my gain was before because my bass was louder, but wasnt sure if my gain was too was too high when i set it with the SRC-LV off but then later turned that setting up.

ugh its hard to explain all this but any help would be greatly appreciated.

thanks

src-lvl is the voltage source level of the rcas when its at zero you have to crank the gains the higher the better you can lower the gain. HPF on 125hz, LPF at 100hz is that amp or HU

Well that answer my question about why my gain knob came out to be not turned nearly as far when i set the gain with my SRC up. thanks man.

um, my Sub setting on my HU are at 100hz (im guessing this is the LPF) and +6 which is the normal bass. My LPF on the amp is also at 100hz (it came this way new) My amp doesnt have a HPF as it is a mono sub amp, but my HPF on my HU is at 125hz.

I just went out and listened to my system, and as long as using the super bass eq setting is ok then im happy with how much bass i can "safely" get. I would probably never have super bass eq setting on with my volume maxed out (my max is 46 according to how i set the gain and i was just listening to some music with the volume at 30 and the super bass eq on and my family could hear it from inside the house)

So are the preset eq's fine to use?

and i listened to some music with my loudness on high earlier today for like a minute max, this was before i new not too use loudness...could i of damaged anything in a minute of play with this on? The volume was not up too high.

thanks

Okay, depending on your front stage, which it sounds like you don't really have one. You probably will keep the LPF at 100hz. That means the sub-out is only getting 100hz and down, same with on the amp.

The HPF on your Deck is for the front rear outputs. set that to 100hz, with the way you have it, you have a gap from 100-125.

Are you talking sub level control? If this isn't the case ignore me. If it is an alpine or most other brands of head units tune with sub level control at max otherwise you're starting out with an attenuated signal and an unnecessarily high gain setting. Start out with the sub getting max signal from the HU before you decide what boosts are necessary. Whether boosts hurt anything and how quick depends on whether you are overpowering or underpowering speakers and by how much, as well as how hard you run your system and for how long. If you're getting a little boost for better bass at moderate listening levels don't worry about it. If you're boosting and also playing at max volume all the time, yes you could kill something.

On basic decks, sub level, bass, treble, mid, controls typically just add a non adjustable slope to a certain bandwidth that you have no control over. I don't recommend using any of them at all.

You set gains, then tune.

My clariion DXZ955mc, I set my gains, then adjust gains and eq's accordingly. Not vice versa.

ok well i set the gain with my sub settings all the way up on my pioneer deh-p3000ib HU. This means i had it at 125hz cross over with 6 bass and sub on normal. The other settings were like this when i set the gain: eq set to flat, loudness off, bass boosters on HU and AMP off, HPF at 125hz, SRC LV adjust (SLA) set to 4 (because this is how i listen to it...not sure if i shoulda had this at 0 or not....first time i set gain i did so with this at 0 and my gain eneded up being much higher than it came out to be this time). Then i set the gain with my volume 75% up, 50hz test tone playing on reapeat, hooked up a DMM with the subs NOT attached to the amp, turned up gain until my desired 31.6 voltage was reached

so did i do everything ok? Was i correct in setting the gain with my SCR-LV up? And so are you guys saying i CAN use super bass eq, because its part of tuning?

thanks

EDIT: The second time i set my gain with the SRC-LV all the way up (at 4) my gain knob reached the voltage right at the "nominal" position on the amp. The first time the gain was about 1/4 further up at the 0.5 mark (this way with SRC-LV at 0).
