factory plugs. The lack of bass response generally is due to one speaker being out of phase 
and the other speaker (s) being in phase. The easy fix is checking these connections to make 
sure that positives go to positive and negatives go to negatives. Basically, double check your 
wiring on each speaker. If one speaker is out of phase, the bass response of the entire vehicle 
can be compromised. 
 

 

 

Too Much Treble, Harshness, or Brightness:  

There are a couple of things here we’ll need to consider:

 

1.  Where are the bass/treble settings on the radio/EQ? Go ahead and flatten out the 

settings to ensure no pre-amp distortion is the cause of the problem. If you’re using 
the radio to test the speakers, try using a CD or directly connected iPod instead.

 

2.  What type of factory audio system did the car have in it from the factory? Was it a 

Harmon Kardon or a DSP equipped car?

 

We then need to assess whether or not you 

were sent the right speakers.  

-If the car is a Harmon Kardon 3 Series

, and you are experiencing brightness, we 

most likely left the capacitors out of the tweeter wiring. We need to send you the 
corresponding capacitors for a 3 Series with Harmon Kardon. 

-If the car is a non Harmon Kardon equipped 3 Series,

 the most likely culprit is 

that we forgot to install the 8 ohm resistors inline with the midranges and tweeters. Do 
you recall seeing a black heat shrink wrapped piece (2” long) inline with the tweeters 
and midranges? Alternatively, another indicator of the 8ohm midrange is presence of 
a white dot on the speaker basket directly below the terminals. If you don’t have the 
resistors or see the dot, you were most likely sent the wrong speakers, and we need 
to get the appropriate speakers to you.  

 

 

A speaker is physically defective, as in defective from shipping or directly from the 
manufacturer. 

There is only one solution here:

 

1.  We will be happy to get a replacement speaker out to you. We’ll need to bill you for 

the replacement speaker, and once the defective speaker arrives back to us, we will 
gladly issue a refund. Once you get the new speaker, please keep us posted on the 
results, as want to make sure that everything is sounding as it should. 

 

 

Missing Product(s) 

If you feel that a product or accessory is missing, let’s check a few things before we send out 
replacements. It’ll save everyone a lot of time!

 

1.  Please check to make sure that nothing has gone unnoticed in the packaging. If 

you’re calling from your office and don’t have access to the package, please bring the 
package to the office the next day so that we can go over with you exactly what was 
supposed to be in the packages that we shipped out to you. Sometimes our shipping 
department uses filler boxes in packages to ensure that your products aren’t 
damaged in shipping, and often times those boxes are mistaken for missing products. 

 

2.  If indeed a product is missing, firstly please accept our apologies. We try our best to 

ensure that all orders are filled as they should be, but we’re only human! 

 Please 

notify us immediately of the missing product, and we will the appropriate pieces out to 
you that same business day, provided FedEx hasn’t already come for the day. We 
want you to get your new equipment installed as quickly as possible, so we’ll make 
sure you have it in an expedited fashion once we’ve been made aware of the 
problem.
