lol... my 1st amp install was when i was like 14..@ 16 i built enclosure in trunk fro 6 12s

first deck install when i was 7

learned from a 12volt pro when i was 12-15 he did install st his house for his uncles shop

im talking farrari 97 toyota supra back when the 1st fast and the furious am out

i just finished 2 15s in a buick

2 12s in a box chevy

2 jl 12s in a old school benz

2 kicker 12s in a dodge intrepid

decks and small stuff along the way

^^^^^^ all from--16 to now 22 im not at a pro and i have not done over 20 cars but im not just starting out allthough the hc600 make it seem that way.. this is a mock up system im doing and i haven't been able to get past this issue since i got this amp 2nd 1 though so im doubting its that.. i am thinking its clipping or catchinga clipped signal but as i said th subs look like there puged in to a socket for a quick second i mean they reach full excursion and then some

the notes dosent even push the subs that far

Im playing bass i love and all other bass tracks you giving the subs all i got and they just back there having fun ,but on chris brown or e40 spooky its just horrable

Could be that the amp is sending a sort burst of dc voltage and the protect circuit is not catching it.

Try turning the gain down some and play at the same volume numbers on your hu and same 0 bass settings. See if you still have the

same problems.

ill do some more testing in a few days ... im tired

the bass should be set at 0 or negatve on youre headunit if you turn up the bass on youre head unit your also sending bass to your door speakers which is bad turn the bass down on your head unit and the gain up on your amp. but not all the way up most amps have max output at half or 3/4 gain

this isnt a stock stereo dude...most aftermarket decks have submoofer control....

also OP could it be the rca's have u tried switching them? also test the coils on the subs to see if they are blown....i think its the amp just sending one hell of a dirty signal

try swapping in another amp

When I run my system daily I always run my bass on my deck to the lowest setting. -8 on my deck. Its hard to say what your problem is. If your box is not right you could be bottoming out your subs or any of the other problems some of the other guys have stated above. Maybe one of your speakers wires is grounding out or it could be any number of things. Id check all my wiring as well and make sure all the connections are legit. Not to sound like a **** but you get what you pay for. I know how it is to get excited and buy something cheap and end up paying the price for it and end up having to buy the good **** in the long run. I suggest you pick up some quality gear. Pay the extra money for quality and you will save money in the long run. I have bought several systems from these car audio forums at a fraction of what you pay at shops and have been more than pleased bro. Just my $ .02

Possibly a Box? I had the same issue.. My box was too small. (Scratching, Clipping, Thermal issues.) What size box are these in?

Possibly a Box? I had the same issue.. My box was too small. (Scratching, Clipping, Thermal issues.) What size box are these in?

stated in OP 3 cubes @ 35 Hz

ive had good experiences with these in 5 @ 30 Hz for a pair.

got new rca's

got a new amp

got hc600

tried a new deck,i dont have a sub setting

bass always at 0

i did some testing today to see if it was the deck clipping ..i lowered the volume and reset the gains 3 times 3 different volumes same issue.

using a 0db 50hz test tone i end up with 19.9 volts @1.2-1.4 ohms max setting without the issue.thats no more than 375 wrms -300wrms im getting no where near 600 watts ..

when i do set the amp at 29 volts i can only play most songs full(set )volume bu on the songs i get the problem i have to back off volume/bass to -2 or more

also with the volts at 29 my voltage dosent go any lower that 13.4

help me please ...its really down to changing my battery under the hood or a new amp..i dont think i can differnt amp (exchanging it from where i bought it)

i also tried the setup on my bros amp ,it set at 750 rms @ 2 ohms and my subs are @1.2-1.4 final load and the issue did not occur i ruled out the box and replaced the amp for that reason.

Well it just sounds like your amp will not put out its rated cleanly. It may still do its rated but only for very, very short burst.

At this point and with all of the parts/ equip swapping you have done, I would say if you want more power you need to get a different amp.

It could also be that at what ever fq you are having the problems at, with box rise and fq, the load may be dropping to much for the amp

to make clean power. Remember, at different fq's, the amp will see different loads.

For example, your amp may be seeing a 2 ohm load @ 47hz and then a .8ohm load @ 35hz.(just an example)

yea i removed 1 sub and free aired it to see if the issue would occur sooner or at all...same issue no change.

The problem also still presented when i was running at higher ohms(4)

 

[thevic24 5,000+ posts]

Well, do you have any other subs that you can use to test with?

Like I said thou, at this point, it sound like you just need a different amp to get the results you are looking for.

 

[lilboom 10+ year member]

all i have is hfi's i got some that are still in the box.. but im thinking

amp

batt underhood

my car has an electrical issue(but being doubted because i connected my power straight to my battery and problem occures with the car off,& i have a 2nd batery)
