your goal is to have something so loud that you can be heard several football fields away while having it sound smooth and pleasant to listen to all at the same time.
Active means being able to assign crossover points and slopes basically telling your mid to only play mid frequencies and tweeters to only play tweeter frequencies while being able to smoothly blend mids and tweets together. Your pioneer 1800bs is capable of doing this, you just need to factory reset the head unit and choose network mode.
Get rid of that alpine equalizer, its doing more harm then good especially if you do the pro audio mids and tweets route. Literally kills your sound stage, kills your blend, kills everything thats going good for you with the head unit you have which is vastly superior to that alpine EQ if you know how to use your head unit properly and do a proper tune.
If you dont want to run more amps then just get a much more powerful 4 channel amp and sell that ppi 1000.4 amp. That only does 40 watts per channel at best. get a 900.4 phantom ppi That amp model does real power and should be the only line of ppi you buy. The BA series are pure cr@p.
