Those would be overboard for this setup. It's not going to sound "good" regardless, so he just needs to keep things from breaking. Oh believe me I know, but he's already stated that he just wants to hear answers about what he wants to hear and not listen to any good recommendations to what he should be doing, so I gave him an answer. I know I may sound like a dick to some in that statement, but it's true, we're all really here trying to help. it didn't help, not to be rude.. but it didn't answer what I was asking either. I wanted advice on how i could make it work.. not other options which is about all i've gotten. It sounded dickish to me.. but that's only if it mattered, it adds nothing to the thread so.. it doesn't. If what I answered to you in post #7 isn't of any help, then I'm not sure how better to help you. The FMOD's are designed to be used when no crossover is available at all or for some reason unable to be used. They're by no means supposed to be used to replace good crossovers in an active setup. If the Sundown 4 channel proto has the good crossovers in it, it will be basic, but do what you need them to do. Of course with the right HU or external crossover it can help much more with good crossover and EQ adjustments. I understand that your only wanting it to get loud, but don't you at least want it to sound decent too? Youtube videos do NOTHING to tell anyone how good or bad a stereo sounds, which is why a lot of people on here despise what Youtube videos have done to the car audio hobby. I also appreciate your candor in your response as well. We're all adults here and it's good to see adult type responses to things we don't agree with. +1 for that sir...
