ok so the amp set up i have is a soundstream rubicon 2500 running to 1 fi q 15 1500 rms sub. i have the sub wired this way from amp.. negative to negative positive to positive. and then on the other side i have positive to negative.. is that a 4 ohm wiring?? my amp is only 1 and 2 ohm stable.. is it ok for my subwoofer to be wired that way?? my imput level is up to about 80% and my bass knob i dont go pass half the volume. the only reason why my imput level is up that high was becuase when tunning it it was at the only level that it picked up good bass.. will this kill my sub??? the FI Q has all the bells and whistles.. its fully upgraded..

WOAH. i couldn't be more confused. ha, is it a dual 2 or a dual 1?

i would love to help you! if you could click on this link and look at the two pictures and tell me which one you have i would be able to tell you what resistance you're at.

and remember i, and everyone else, needs to know if its a D2 or a D1 sub. Just becasue the pictures say its at a certain resistance doesn't necessarily mean that that is the case for you because those diagrams are for a D2 sub only.

What head-unit do you have?

What coil wiring options do you have? If its dual 4 then its wired at 2 ohm. Therefore 1700wrms, im pretty sure that soundstream underrates there products. But the Q could handle it aslong as it is not full tilt 24/7 and is a clean signal.

sorry its a dual 2 ohm voice coil..

which one is your setup? It kind of sounds like you're at 1ohm but i can't tell for sure

the second one.. im just a bass noob dont want to kill my amp and sub.. i also have an extra battery on back..

If you have that second one and a D2 FiQ then you are wired at 4ohms! so about 850 or 900 watts which is good!

Now, what head unit do you have? and what is your gain set to on the amp?

i dont know exacly what deck it is.. it came with the car its a jvc same specs but not the same.. JVC KW-XR810 In-Dash Double DIN Car Stereo w/ Bluetooth this is the newer version with out the subwoofer outputs. then why do i feel my subwoofer getting hot if its only set up for 900 watts??

Do you have a volt meter installed to measure your voltage or a DMM to measure your voltage? Turn the gain down some, probably 60% and see how that treats you (its probably not the right way but 80% is to high). You want to make the amps signal match the headunits signal, which 2.5 volts

Probably because you're likely clipping the amp with too high of a gain or bass boost, which sends more power than 900 watts to the sub. At full clip it could be near double that.

Also, moving to an Fi section since this is just a question, no hello.

Also make sure your not using any Bass Boost on amp or headunit, dont use the loud/loudness feature on your headunit either.

welll the FI Q i bout is fully upgraded.. dont know how to explain.. bought the upgrade so it could handle an additional 500 rms watts.. so the sub should be good for 1500 wrms so the sub should be good right even if i turn the bass knob that came with the amplier all the way up right??

Not if your clipping the signal, then no it won't be great.

im not using any bass boost on the head unit just the bass knob it came with.. i ocassionally turn it up.. when i want to feel the bass hitting my chest.. lol

"Clipping is a form of waveform distortion that occurs when an amplifier is overdriven and attempts to deliver an output voltage or current beyond its maximum power capability. Driving an amplifier into clipping may cause it to put out power in excess of its published ratings"

OH OK.. DO YOU THINK I COULD DO THAT to a soundstream rubicon rated at 2500 rms at 1 ohm? if i install another subwoofer and turn the bass knob all the way up?? just asking some one with more experience before i go out and try it myself and blow out an amp or the subs

It's about how the gain is set, if it is matched to you H/U then clipping won't be an issue. If's it's just turned all the way up then yeah it will.

ok my head unit is 2.5 volts my amplifier has a switch to set between 1-2volts and to the right it says 2to8volts.. i have it turned to the left would that be right?? and my input level is about 70 percent turned up.. becuase any lower and the signal dissapears..

Can you show me a picture of the settings on the amp?

And which input level?

here it is.. the subwoofer is wired at 4 ohms..box is sealed 2.3cubic feet per sub. just noticed the imput sensetivity got switched.. hehehehe the bass moved it..
