I think you bought products that are only in business because of marketing. For example, that BOSS amp is 99% rated at 1000w MAX. Which means on a good day, its doing 500wrms. And even if it was making that much power, its THD is going to be pretty high, and it'll clip easily.
10 Years ago Audiobahn used to make good speakers, now they're all junk. And in bandpass box? That setup is going to be dirty, messy, and won't get all that low. Just like in everything else, you really do get what you pay for. Lower end stuff like what you've got sounds like ass and is common for people who don't know much if anything about audio to buy.
People think you can just jump into mobile audio and have a good sounding system. Yea, you can spend little money and get loud, but it'll be like having sex with a lady wearing a mumu. You're still having sex, and she'll scream, but DAMN you could do a lot better. Just like everything else, if you do some research, and spend a little more money you can get a volleyball player to fuck. Yeeaaaaa bbbboooiiiiiii
