FACTORY AUDIO UPGRADE

Hey guys,

Hoping to see if I can find some answers to an audio issue I'm having. I have a 2014 Tundra Crewmax limited with the factory JBL audio system. I have been upgrading all the audio in it since it is a bit weak IMO. I am moving to an all JL audio system. I am keeping the factory head unit and using an LC8I. So The tweeters I got said I needed to splice into the factory wiring So I did that in order to get power to the tweeters. Since doing that I believe I am getting distortion. Any time I have my volume passed a certain number the dash speakers start popping. Trying to figure out where I went wrong and resolve this issue. Thanks in advance for any ideas or suggestions.

 

Give us a list of all the speakers and amp(s) you are using.

The tweeters should have been connected to the passive crossover that came with your speakers.

From the factory, the dash and center speakers were powered off the head unit directly, and the door speakers went through the factory amp under the passenger seat.

 

I have the C3-600s in all four doors (woofer tweeter combo). Each of those came with their own crossovers.

The front doors the tweeter is near the window and the even with the tweeter connected to crossover no sound is produced. I spliced into the factory tweeter wiring and connected that to the crossover and finally got some sound out of them but in doing so the dash speakers start popping. Keep in mind that I still have the JBL speakers in the dash.

For the corner Dash speakers I will be using 2 C7-100ct's (Backordered)

Center Dash I will be using C7-350cm. (Backordered)

As stated earlier I will be using the LC8I since I wont be changing out the factory head unit.

Finally for the amp I will be using the JL Audio XD800/8v2.

I have the Stealth box connected to the factory amp with pretty cheap line output converter on a 1500w Crunch amp but will be swapping the crunch amp with the VX1000/1I monoblock amp

 

Where is the LC8i being used? When using the LC8 you need to rewire the tweeters. The LC8 is an 8 channel signal processor. So either you use the LC8 or the crossovers. No need for both.
