Ok I just had my new stereo system installed. The speakers I am running are Alpine Type X. The amp is an Alpine V Series 100X4. Anyway when I turn up the music pretty loud everything sounds good, but on a few songs with heavier bass, the speakers make a farting sound. They are brand new so I am pretty worried they might be blown already? It only occurs when I am set really loud, like on the threshold of where you want to listen, if I stay just under that it sounds awesome. Could it just be the speakers are underpowered?

did you do the install yourself or by someone else? go back and check/follow every single wire and make sure everything matches. i recently had mine hooked up and the wires got crossed between the amp and sub, on both subs. while it was loud, the bass wasnt there, i fixed it in ten minutes, and now it pounds! good luck!

A shop installed the system for me. And thanks for your advice but I found all my issues.

The amp gains and Hz settings weren't jiving with my head unit settings. A friend of mine who used to compete came by and helped me with a foundation with crossovers, EQs, and gains settings. After a few hours of tinkering and fine its hitting just perfect. Sorry to waste everyone's time.

But I will post pics soon.

If anyone cares my set up is as follows:

Kenwood Excelon DDX814 Head Unit
Alpine Type X 6 1/2s in the front doors
Alpine Type S 6 1/2 in the rear doors
Alpine Type S 12 Inch Subwoofer
Alpine V Series 100 x 4 Amplifier for the components
Alpine V Series 500 x 1 Amplifier for the Subwoofer

do you happen to know how many dbs you are hitting
SPL:
Peak 109.9 dBA
Average 97.3 dBA

Hope that helps! Pretty modest, but it does the job for me. I tested on the song: Monica ft. Dem Franchize Boyz - Everytime Tha Beat Drop. Might not be the best song to test on? I am no sound pro. But I put the reader on the passenger seat and played that song at about as loud as I was comfortable pushing the system.
