Possibly you need to return the amp and get a new one cause that could mean an internal problem and its deffective, you could try replacing the fuses or try changing the ground wire, this problem is very unusual

SOURCE: Hifonics BXI 1606D problems

it may be a wiring problem you need to make sure all the speaker positives and negatives are correct. I sell alot of hifonics amps and have never had 1 do that. it may also be a bad rca cable. if it only does it when you use the filter i would say not to use it also make sure the gain is no more than 3/4 turned up and the bass boost no more than 1/2. if you have a dif amp try a temp setup using it and if it still does it its a wiring issue. also try 1 speaker at a time on the hifonics and keep adding 1 till it comes back it may be a bad voice coil on 1 sub .

SOURCE: what is the subsonic filter for?

Hello luckybear22,

The simple answer is that a subsonic filter prevents frequencies below the threshold of hearing, hence subsonic, from being sent to the subwoofer. Such frequencies result in a loss of available amp power and in the extreme can even damage the speaker.

Hope this helps.

SOURCE: what should the subsonic filter be at

The subsonic filter is to help your system's overall performance by blocking frequencies that your subwoofer cannot effectively produce. For example, if you have a single 10 inch sub, it's not likely to be able to produce sound much lower than 60-80Hz with any respectable volume. If you have the subsonic filter on and set to 60Hz, it will prevent a 40Hz tone from being delivered to the sub. If the subsonic filter is turned off, your sub will get everything, and it will try to produce every sound. If it gets a 40Hz tone, it will make the sub work extra hard without any audible noise. It'll just degrade the overall so the answer to "shoud the subsonic filter stay off" would be "it depends on your system" but in most cases, you should keep it on, and set it to the low end of your subwoofer or woofer range. This also applies to filters on mids and highs.

MOST OF THE TIME U WANT UR AMP RUNNING UR SUBS TO MAKE THE SUBS SOUND REALLY DEEP AND HITE REALLY HARD BUT BE CARFULL WITH THE BASS BOOST IT CAN BE TO HIGH AND CAN BLOW UR SUBS, NOW WITH UR AMP RUNNING UR MIDS U DONT WANT A LOT OF BASS MAYBE NOT AT ALL CAUSE UR SUBS WILL HANDLE THAT, SO U WANT A LOT OF TREBLE WHICH SHOULD BE THE LPF, O AND ANY WHERE FROM 6DB-12DB WILL BE GOOD.

I HAVE A HIFONICS AMP THE CREOSSOVER SWITCH ONLY WORKS ON HI AND A LITTLE BIT ON FULL BUT ON LP/HP THERES NO BASS WHATS WRONG


What kind of head unit do you have? Does it have a xover setting on it also? You may be using an output that has already filtered out all the bass. Look in your settings and change it to full if possible.

What is the subsonic for on the performance teknique amp


The subsonic filter is used to filter out the bass that is too low for the human ear to detect or hear--remember the lower the frequency or bass note that you try to play the harder the amp has to try to reproduce it-so by filtering out the bass that you cant hear it saves life on your amp and subs and your not missing anything anyways cuz ya couldnt hear it to begin with.

Brutus 1206D


set the lp filter to about 100 to 125 (or lower if want seep boomy only) , put the bass eq no more than 75% but i would recommend no more than 50%, gain is to match the sound not to adjust power with so it is a user preference start all the way down and slowly go up till u hear distortion then turn it back down by about 10 - 15 %, phase shoild typically be at 0 degrees, subsonic depends on if you r using sealed or ported ported turn it all the way down then adjust as needed to get rid of the lower sounds you dont want (muddy sloppy sounding bass) if sealed turn it all the way up to at least 35 hz.

No output


Maybe you should check your remote wire!

Amps


The phase is used to match the phase of the sub, highs amps. If you don't know how to determine if there's a phasing problem between the two amps and you can hear no difference, leave it set to 0.

Many people use the subsonic to prevent over driving speakers in a ported enclosure. If you're using a sealed enclosure, leave it set to the lowest frequency. If you have a ported enclosure, set it just below the resonant frequency of the port in your enclosure.
