Not as much bass as expected

Recommended Posts

Hi guys,

I’m definitely a beginner when it comes to car audio. Here’s the jist of my situation:

 

I decided to tackle a subwoofer build. In the project I installed the Big 3 upgrade with 0 gauge CAD, aftermarket head unit, hifonics Brutus 2416 super class D, sundown audio SA-10 rev 3 (750 Watts rms), and designed and built my own. I am running the at 850 watts @ 4 ohms.

 

The problem:

After having the build for a month now I’m not as impressed with the bass response as I once was. I understand that this could be due to becoming acclimated to the sound system, but even for pushing the sub 100watts over rated rms in a very small cab (ford ranger ext cab) you would expect it to be more intense than it is. I am also fairly confident in the design of the sub enclosure because of long, careful hours of working with WINISD and google sketch up. Just in case this helps it’s tuned @34 hertz.

 

I’m wondering if it is possible that the hifonics amp, not being the most reputable brand, has something to do with the power output. When I tuned the amp I made sure to do enough research as I have heard some horror stories. The ‘gain’ filter is set at its most open or highest position and I am still not experiencing clipping of ANY sort. Does this seem unusual or is it that I am not that experienced and 850 Watts is not an especially big amount of power.

 

I am also wondering what you guys think about wiring the sub to the amp at 1600 @ 2 ohms.

 

Please only helpful comments and suggestions

Thanks for the help!

What's the aftermarket HU brand? I pray it's not Boss lol Also what's your enclosure specs? cu ft.?

 

Even running the sub at 4 ohms isn't a whole lot but should still provide a little bass.

You would be lucky to be getting 500 out that amp at 4ohm. Wire it to one ohm.


i told wife guy on here pm'ed me wanting to buy my amp she said tell him it not fs (cause she knows i'll spend more $ on new one) and told her i wanted d2 sub for bday next week she said tell ya'll i'm to old to go down to 1ohm lol..

@kr15 it’s a 2ohm dvc

@Boomin Tahoe it’s a pioneer something or other I would have to check. The enclosure is 1.25 cu ft. Don’t get me wrong it does bump a little but definitely not as much as expected.

@papermaker the only reason I’m worried about wiring to 1 ohm is because of my stock power plant besides big 3. Do you really think 500? I have a friend that showed me his cheap 350w jbl and it can compare.

Do you guys suggest that I check the wattage it’s putting out? Or purchase a amp?

Wire that sub to 1 ohm....because that amp has a little inflated numbers, so 1 ohm should be better for ya. Just watch the gain if it gets a little heavy on ya.

 

1 ohm will do 2400...but I bet it's way less than that.

If its a D2 sub you can only wire to 1 ohm or 4 ohms. If its a D4 sub you can only wire to 8 ohms or 2 ohms.

 

drop the ohm load Learn what box rise is. But yeah hifonics amps are poo buuut it should get you to where you need to be at considering its just an SA series.

YOu need to reset your gain

It will be too much / clipping if you leave it that high

Thanks guys I really appreciate the help. I’ll drop it to 1 ohm and let you guys know how it does. Maybe in the future it’ll be time to put some money into a new amp.

 

That amp will be plenty for a single sundown SA 10 at 1ohm... it’s either your enclosure or your install/settings are messed up

Use the hifonics. Wire to 1, and set gain very clean.

Does anyone recommend an amp that puts out reliable numbers? Whether it is cost efficient or not?...

 

Just use the hifonics. But if youre looking for a cheap amp that actually does close to what it says I have an Audiopipe APCL1500.1D its proven to do close to its numbers for a little more than 100 bucks. it isn't very energy efficient though. It really is garbage though. Buy from a reliable brand. Although I can say the Audiopipe is better than most of the poo at the end of the day poo is still poo.

Thanks guys this really helped me out! Everything went according to plan:

Dropped to 1 ohm

Fussed with the gain/ no clipping/ distortion

No devastating voltage drop/ electrical is fine

 

There is a vast improvement and now I know more about my amp and it’s capabilities.

Hifonics is hifonics

oh yeah we can recomend several (guy here test amps has a utube channel) but what they saying is with box rise sub may only be getting 3-400 rms.. wire it to 1 ohm turn gain down to 1/4-35% see if that sounds better and learn how to adjust gain so amp don't clip don't turn hu volume over 75-80% max.. also do u have lp xover at like 80-120hz? if box is ported do u have the ss filter set close to port tuning or using it at all?

oh well i see i'm behind on this thread.. check your amp settings and here's a video to help u set gain at least close to where it should be use a 50hz tone i'd say a good setting for 700rms would be 26.4v or so (so 25.5-27 is good just don't go to high with hu volume)

Dude, get over it. I quit talking about it a day or two after I said something. You should do the same.
