ok so my whole system is not in the best shape. the rear driver side speaker at times will build up static, then let out a loud pop and the static will stop. then my drver door speaker cuts out sometimes. theres kinda of a ringing noise coming through all the speakers, you cant really only hear it when the music is low, or muted (and no its not a winding ring). now for the 2nd part. i listen to metal and my sub doesnt get all the notes on the parts with double bass, if theres a lot of double bass, it just sounds like one long bass hit, and when theres a lot of double bass, the volume of the sub decreases as the bass continues. also my speakers seem to kind of distort at high volumes. im not blasting it, but loud enough to where you have to turn it down to talk. are these problems due to a poor install? or should i upgrade my system? im running infinite kappa speakers with a JL 300w amp, and a kenwood excelon 12" sub with a rockford punch 600w amp. and my head unit is a pioneer deh-9300.

What are the rms specs on the amps and speakers? Also: What kind of box is the sub in? A 10 inch in a sealed box may be more suited to your needs for the ultra tight- fast bass.

 

It's definately the install.

 

It's kind of hard to tell over the Internet, but the equipment you have is OK, model numbers of all the equipment would help.

The first thing I would look for is proper speaker installation and wiring, I am guessing a short in one of the speakers or wiring, or you have a problem with the JL Audio amp, I am assuming it's a 300/4, 4x75W RMS, [need model number of the speakers].
There are a number of things that can be wrong that is causing the speakers to distort at higher volumes, first of coarse is improperly installed speakers, next would be an underpowered amp, or a lack of current to the amp, if the speakers sound good at high volume until the bass hits, then it is definitely a current issue, the most common cause is running one power lead, [no matter what gauge] to a splitter block and then running 2 leads to the amps.
When the sub amp starts working hard, [lots of loud bass] it will try and draw the current it needs from where ever it can, and if the high-pass amps power supply is closer to the sub amp then then sub amp is to the batt./alt., the sub amp will draw it's current from the high-pass amps power supply, [specifically draw down the caps in the power supply of the high-pass amp.
This means two things, both the sub amp and the high-pass amp are not getting the current they need resulting in neither amp producing the wattage they are rated at without high distortion rates.
So again I need model numbers of everything, gauges of power cable used and what type of fuses are being used on the power cables, ground cable gauge and where and how they are grounded to the cars chassis and how long the grounds are.

There is no reason for the system you have to sound anything but pretty good. 94
