That amplifier is 900W x 1 @ 2ohms.
If your subs are 4ohm SVC wired Parallel, resulting in a 2 ohm load, each sub will only see 1/2 of the rated power. (450W ea.)
Your gain (sensitivity) setting should be between 75% and 85% to max. You will be fine.

Reduce the amount of boost or, better yet, turn off the bass boost. With your installation, overemphasis on the bass is causing the rattles and distortion

Not gettin enough bass


Hello saini_jatt_2, On the JBL3501 700 watt monoblock, you have adjustments for low pass and a setting for boost marked DBO, allowing you to select and boost the frequencies sent to the subs. If your amp is not the 3501, but a different JBL amp, the settings may be different. Set the LP to either the white dot (about 100Hz) or slightly below to about 80Hz. Set the HP to about midscale or slightly higher. Set the boost to wherever the bass sounds best. One other setting that will affect bass volume is the "input level" or gain control. It should have been properly set by your installer, but you can "tweak" it for best performance. Turning it up increases the sensitivity and matches it with the output from your head unit. Too high will cause distortion. Too low will result in less bass. So you want to set it just to the point that you begin to hear the distortion and then back it off slightly until the distortion disappears. Hope this helps.

How to adjust the controls and gain on my kenwood 9104d 1800w amp


Hook the speakers in series to decrease your chances of blowing the amp and/or speakers themselves. And at high volumes make sure that the bass control is set for flat response.

Set your HPF and LPF on the headunit to match the crossover on the kenwood amp.

I have the same amp, it's really not difficult to figure out. Try these settings, For the AMP: Bass Boost: 0 Crossover: 150 Level: 1

Now just go into the menu for your head unit and make sure you set the crossovers to 150 or whatever option you have, just make sure they match.

Simple.

May i suggest removing the equilizer unless you can adjust the settings for each amp seperatly. The amps themselves will allow you to add bass boost and treble boost. I think the problem your having is trying to run to much bass through your system causing it to distort badly.
