Pops from speakers.

Hi, Im running Infinity Kappa's 693.5i, there rated at 110 RMS...

Now I have a rockford fosgate 75x2 amp pusing them.

So why do I get pops at max volume? If my HU is rated at 25rms and 45 max, does the max volume mean max power from HU??? And still, My gains on the amp are all the way down, so why am I getting pops??

I hate RF

 
Yup

35-22,000 Hz

2-way external crossovers (18 dB/octave, 3,500 Hz high- and low-pass)

recommended power range 2-110 watts RMS

peak power handling 330 watts

Ya i copy and pasted, im soo tired.

you said the amp was powering them---- so why do you refer to the HU output? --- you did you use high level inputs or something???
 
I use the RCA's for my rears??? They are powered right???

Or is it just the amp's power on them??

Are you saying the RCA's from my HU are not powered at all?

Thanks

I am also experiencing popping. It happens on the peaks of loud songs if the gain is set too high. The thing is, I honestly believe that this is happenning way before the amp clips and way below the rated power of the subs. I'm hoping it's something in the installation that I can fix. What are the chances?
p.s. See sig below. The USX amp can do 160 W X2 bridged, and my RMB8's are supposed to handle 175 each. I have to limit the amp to about 60 watts / ch if I don't want any popping //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

This shouldn't be happening...when the subs are pretty much gone, they continue to pop even when being powered correctly. Your subs might be partially blown. How old are they??? Are you the orignial owner???

Naw...should not make the subs pop...the amp would be hot.

 
check your ground if your not getting a good ground if your ground is not good you could be having energy splurges and at higher levels the more the power the more the pop what is your head unit grounded to did you use the factory or did you make your own how are your amps grounded:nono:

Brand new. I put a 50 Hz test CD in the deck and a 'scope and DMM on the amp to set the gains. When I got up to about 16 vrms (64 watts) they "buzzed", probably the rear deck vibrating. I stopped there. Then when I played some music, they popped on the peaks so I had to back off even more. They're not loud at all... in fact the Infinity 6X9's are just as loud on only HU power. I need to get more power to them somehow.

When you turn the volume up, does the sub fade out???

Nope. Keeps gettng louder up to the point where it starts popping. Only good thing is the Kickers at least go to 30 Hz, so they're filling the void for the bottom end but no where near loud enough.
This weekend I'm gonna take the RMB8's out and mount them to an MDF plank and see if I can get them to take the power they're supposed to. I'm curious to find out if it's the speakers or the installation that's lame.
