So let me ask some of you guys this, and I'm sure those who respond will give an informative and intelligent answer (which is why I even bother writing still). With bass boost being available on most EVERY aftermarket amplifier (except some Alpine amps) which suggests there is a safe means of using the feature or too many manufacturers would have warranty claims, how can you use it without clipping? Turn your bass boost all the way up with your overall volume on your headunit down, and you will of course hear nothing. Turn it up one notch then the bass defeats everything else. Another notch up and the bass increases exponentially until you turn it up to the point of audible distortion caused by the woofer reaching it's maximum excursion or clipping. So I ask again guys, is there a way of using bass boost without running the danger of clipping?

 

Its so that crappy Sony amp and sub you bought at WalMart can be clipped to sound like they're wangin (or XPlodin) hard on your local hip/hop radio station. With a properly tuned system, bass boost becomes an irrelevant and redundant (not to mention less accurate) option of controlling the output of your subwoofer in relation to the output of your speakers.

 

Plus bass boost helps make a sale to people who don't know any better.

"Well amp A has more boost than amp B so that must mean it will make my sub louder." I could honestly imagine quite a few people thinking that way.

Sorry bro, I have a Rockford P300.1 amp bought at Ultimate Electronics and two 12" Rockford shallow P3 subs I got from the same place. Also, I listen to rock music. And I do understand that with a properly tuned system, there's no need for an emphasis on bass. But you know what? There are some headunits out there that do not increase the bass when a certain level of system volume has been exceeded, its this way mainly with stock headunits. So bass boost to the rescue.

You can't seriously believe for one second that electronics manufacturers will PURPOSELY put a feature in a popular piece of mobile electronics equipment that ONLY does harm to components. Do you know why they won't do that? Because if it did excessive damage to subwoofers and the amp's internam components, then it would cost the company of the amp and the company of the subwoofer lots of time and money to fix all the "faulty" voice coil and electronic burnouts. Not only that but don't you think the customer would be turned off by a brand that constantly burns out? So sorry bro, that's not the answer. If N2O only did harm to a motor, then no one would sell it. But since there are safe applications for it if installed and tuned correctly, it's allowed to be on store shelves.

So, anyone else?? How can you safely use bass boost without running into clipping, or the danger of???

 

what happened to the ported box thread?????

 

Alright "bro" I don't care where you bought your equipment. I also don't care what music you listen to. Because none of that matters. And I do know that some headunits dont have a seperate sub output channel. Hence the use of the gain sensitivity control on the amp. But turning that up will lower the overall volume at which you can play music. But go ahead and boost you will shorten the life of your system. When youre paying 600-1000 dollars for a sub stage you can afford a 100-200 dollar radio.

 

Well I'm glad I have an $800 Alpine with HPF, LPF, subwoofer volume control, and an amp connected to the subwoofer preout then. And what's your problem MAN? Are you upset because you think there's a world of harm in bass boost but I'm trying to explain that there are actually applications for them that do no damage? If you're so smart then genius, maybe you can explain why there's even bass boost on amps if it's nothing but harm.

 

Hey rolltide4x4, I don't think I asked you yet, but do you have a seat lift kit in your truck? I just measured in my truck and unless you build a box using fiberglass for the bottom, your box will stick out around 3 inches or so to get two of your subs under there, and that's firing up towards the seats. And if you're putting two of them under your seats, you'll only be able to do a sealed box if you didn't lift.

 

i donot have a seatlift on my truck it fits the pioneer premeire shallowmounts quite pertly.... im helpin my boy with his sub set up

 

How does it cost the company money? You blow their sub, they ain't replacing it.

Would a customer be turned off by it? Yes, but if they are using bass boost to solve their problems, they probably should be buying the cheap shyt to begin with.

 

I pretty much have to agree here.

The BB is made to add extra emphasis around a certain freq. Now, at times an extra 1-2db is necessary to use to defeat a dip in the cabin (in some vehicles) but at the same time the gain must be reduced in order to not introduce clipping. Get an O-Scope out and watch what happens. After gains are set properly then add BB. The tops and bottoms of what was once a nice, pretty, consistent wave will begin to be chopped off. This will then lead to a wave beginning to look more "squareish", this will then add extra power under the wave. Not very safe at that point for the driver.

 

You asked the same question 5 times. Each time in a nearly illiterate paragraph.

 

hen32:
I've asked EVERYONE, not just you, the same question 3 times, not 5, and only Low e red has given an answer. I haven't seen jack from you so quit your bitching BRO.

Low e red:
I know what you mean with the clipping on the amp with bass boost, and I am very familiar with what it is, and it can sound REALLY (vs slightly) horrible depending on the circumstance. One of my buddies tested my system with his O-scope. With my just-above-normal listening level, my current HU EQ setup, my current gain adjustment, no clipping is shown until +5db. We put a bass cd in my HU with a sine sweep/test section and he tested it between 30hz to 50hz. I don't listen to music with my amp loud at all for the reason I have kids that sit in the back seat sometimes and I personally don't want their hearing to go bad because of me.

 

If you have said HU, why dont you try using it?

 

...? Are you kidding me dude, seriously?? Something tells me you aren't at all reading any of my earlier posts yet you are making lame assumptions? You know what? You aren't worth my time. Please don't reply to my posts, and I won't reply to yours.
