So bear with me. I am in the process of collecting the pieces to go active. I have ordered the silver flute 6.5s the eBay Alpine tweeters and am debating pioneer head unit vs Dayton dsp. I just don't think the Rockford t1 components are very good and I am not really fond of the Kenwood head unit I have. But 1 of the questions is even on the current equipment I can play some songs that sound absolutely wonderful. Some sound like garbage while others I can tune via eq over a few times of listening and they are ok. I understand that not every song sounds good in a system, but there are songs I have listened to a million times that just aren't right. Then there is the no bass at all vs having to turn sub volume all the way down. I mainly use Bluetooth,some cds. Will a dsp "even things out" so to speak? Some times it sounds ok at moderate volume but at full volume sounds like garbage.Not running any rear speakers. I will also need to work on my sub stage but that's another post. A little info, 06 Avalon stock electrical, big 3. Don't know if voltage is an issue? Rockford t600-4 for mids/tweets, punch bd1000 for subs. I have use sound dampener sealed doors as much as possible. Any input would be appreciated, and thanks for reading my long jumble hope it made sense to someone.
