Hey there, I have recently decided to go the DIY route to getting a set of component speakers in my truck. I think I will be getting some Seas Excel Mids or something similar with Morel Tweeters. Now onto the crossover, how complicated is it to build one? What do you all have to buy and is there any resources related to this? Or would it just be better to find a crossover somewhere that is already built and buy it instead of building it? Is the crossover customized to different types of music, speakers, power going through the system and such? Ahh so many questions. Anyways Thanks in advance for any info.
