low notes send amp into protect

[aimone 4]

ok so i have a bazooka 500wrms mono im running until i get my saz-1500 fixed.... its running a fosgate power hx2 at 1ohm. its a damn good amp for the brand. i dont know much about it but lately since i got a h/u instead of my mp3 player it goes into protect when the bass hits real low note like on bass i love you for example the real low note when u get major excurssion it goes into protect. is it cause its not 1 ohm stable?

gain is about 2/3 up

frequency is all the way down

bass boost is about 1/4 up

sub level on pioneer 680mp is at about -10

thanx in advance

If the amp is not 1 ohm stable it's going to say nope no more output for you! Need to turn the bass boost off on the amp. I would avoid the really bass heavy style music until you get the SAZ-1500D back.

[///M5 2,833]

2/3 the way up is NOT a valid gain setting. I bet you are trying to make that poor amp output way more than it can. Highly doubtful that it can come anywhere close to the 500w you spec as well.

ill post a pic of the guts when i get home they suprised me when i opened it up. but i know its not turned to far up cause ive had it turned up alot more and it never shut off.

[Randal Johnson 544]

The amp could be starvin for battery power. How many batteries you have? upgraded power cables? I'v been told that amps only shut off like that when there is a problem. Amp may be gettting too hot to quick. Running at lower ohm loads require alot of battery power. Expecially trying to play lower frequiences. Hope this helps. Just a suggestion sir.

i hope you don't bass boost that SAZ-1500.

Like said earlier: give more information on your electrical, dont use bass boost period, make sure your amp can handle a 1 ohm load and set your gains correctly.

Regardless of the amps guts, it will only send out so much power (doesnt matter if it puts out 300 or 600 watts, it will only put that out and no more). Either your not giving it enough power, your running at an ohm load the amp cant handle or your trying to make the amp do a lot of power it is not capable of (remember it is not the SAZ-1500D). If everything is up to par then just turn it down till you get your amp back, pretty much all you can do for now.

[shizzzon 461]

Bazooka only makes 2 amps that are rated at 500w and BOTH are only 2 ohm stable.

You better stop running it like that or you could damage it.

[aimone 4]

ok i turned the bass boost all the way down definately sounds better. my ol lady dont like it loud as shit like i do so havent got to test the lows yet today.

electrical wise i have

brand new stock alt

new $50 battery

big 3

i have two volt meters the one on my h/u doesnt drop below 12.5 cranked on lows and the other one runs at 12.8 cranked on lows. so i should be good there

but i think cable guy is right about getting to hot to quick while running 1 ohm

ive been running this amp at 1 ohm for bout 6 months no problems until i got the new h/u

i think the bass boost had sumthing to do with it too.

so when i get my saz1500 back the only things i should adjust are the gain and the lpf right?

[Julian 641]

define "low notes".

When playing BELOW tuning frequency there can be an impedance drop. dropping your final load to a lower load making it clip/go into protect.

[kirill007 52]

He said he went from a MP3-player to a headunit.

The output voltage on a mp3player is lower then a HU.

So he should readjust the gain and put bassboost at 0.

[aimone 4]

yea i dunno wut the output voltage of the mp3 player is but the h/u is 4v and i did readjust the gain and boost when i hooked up the h/u. now boost is all the way down

by low i mean low like i said earlier the lowest note in basstronics- bass i love you or the lowest in jeezy's - put on

[Julian 641]

That's very low what is your tuning freq on your box and what is your sub sonic freq filter set at

[aimone 4]

its tuned at 30 hz.....its 4.6 cu.ft w/ sub and port displacement

the amp does not have subsonic just gain, frequency, and bass boost knobs

im building a new box tuned higher like 37hz w/ kerf port and double baffle

Im lost, you want to hit low notes but you want to tune your next box to 37hz?

[Duran 387]

[Julian 641]

it has a fixed SSF on it so its probably around 35~ hz or higher. don't play the low notes, or turn your gain down, or get another amp with a variable SSF, to produce lower notes at a high volume it takes an extreme amount of power, it takes much more than it would 35+hz.

[aimone 4]

yeah i love the lows it hits but the lows is all that really sounds good. 37hz was an estimate what would you recommend to be tuned at for a little higher response while still hitting lows? i really dont know jack about ported boxes. here in oklahoma most people i know use prefab ported or sealed boxes so i could use the knowledge.

amp is doing ok now until it gets hot i only gotta deal with it for another week and ill have the sundown goodness lol

[jcarter1885 995]

33-35hz sounds nice, check your wiring ohm load so it wont damage the amp if wired to a lower ohm load than the amp can handle. Stop pushing the amp that hard, it wont make any more power by turning it up just gonna produce more heat until you trash it.

[Duran 387]

If you want a good balance of what you think is low and high bass, tune to 34-35 Hz.

And 37 isn't so different, perhaps for the OP even better. I really don't understand the fascination of the recommendations of low tunes. Sure they have a purpose and out of all the people commenting in this thread they would serve a purpose to me the most; however, there just isn't so much stuff in music that low and considering most drivers are built to be tuned higher regularly that makes sense. Modelling software makes things worse as people have no idea what the curve means or how effective cabin gain is. Last ported box I built was tuned higher than 37Hz, albeit for a reason, and no this was a box for my sister not for me personally. My design though.

[aimone 4]

ok once again the amp isnt turned up very high only thing turned up is the gain and its a lil over halfway. and as far as trashing it from heat i could care less it was free and i have 2 saz1500's gettin repaired......

^^^^didnt mean to sound like a dick above ^^^

m3. . . . i like the lows because of the feel and the pressure so thats why i tune low..........my last setup was 2 treo 15's in a big ass box tuned at close to 50 hz and it slammed really hard. it just didnt hit low's they sounded nasty. this is gonna be my first setup with all "Real" equip .my electrical could be better other than that there will be no junk equip. im goin for crazy airflow and flex just to show off with. ill go for SQ next setup when i get board with this one.

if i decide to keep it in the back seat and seal between the cab and trunk how should i face the sub and port ?

Your missing the point of tuning low Sean, his drivers will be more efficient at tuning making them louder at and around tuning, that is good for someone who likes low frequencies but bad if they tune too low because they risk mechanical failure if they play too far away from tuning. That's why I recommended 34-35 Hz.

You know just as well as I do that 150 dB at 30 Hz. is far more impressive than 150 dB at 70 Hz.

LOL, not missing the point at all. I understand exactly what tuning does what, but there is a HUGE misconception across the board with people new to this site (and some who have been here for a while) on the notes that are actually in the music they listen to. As for impressive, again who cares if you don't listen to music that plays those tones.

[aimone 4]

i listen to rap/hiphop-i.e. rap gucci mane, jeezy, stuff like that and real hiphop stuff like atmosphere, sage francis, immortal technique....

and occasionally some metal like slayer and dethklok
