agreed -- to each his own--but i'm 33 but still 16 at heart. btw i'm also medically retired army.10 years.

 

Your speakers/amp are "clipping". You are trying to push the amp to hard and its causing the speakers to pop. You need to check the electrical lines and make sure your alternator/battery are okay. Check your grounding points. Clean away any painted surface to bare metal.
Good luck. I had the same problem now its gone.

 

+1 ^^^^

You could also use a Cap if you're not already to help and check out what guage wire you are using. If the power draw is too great for the guage wire you are using or the peak power current needs cause a drop in line current, the Cap will help.

 

or maybe......maybe you have your amp overloaded. what impedence and how many voice coils? are you wired for 4 ohms, 2 ohms, 1 ohm? is your amp stable for that ohm load? same problem could happen if you have a 2 ohm stable amp and have the subs wired for 1 ohm load.

 

True^ Definatly something to check as well

 

very new here but thought i would add. if it is a four channel amp and you have two channels bridged to each woofer the final impedence of each woofer has to be at least four ohms. almost every four channel amp will be two ohm stable but that is per channel. two channels bridged at four ohms makes splits the impedence to each of those channels. if there dual four ohm woofers there probably seing two ohm mono to each pair of channels.....=1 ohm per channel......too low. i have worked in this industry for about 6 1/2 years in indiana so far and that seems to be the most common prob with running a four channel amp on two woofers. good luck

 

You do know that Lightening audio is the made by Rockford Fosgate right?

 

^Exactly why I asked him.
