Remember too, that some MFGs are specific to a purpose.
IE:
Fosgate has always been know for PUNCH stuff and hard-hitting indestructable bass.
Eclipse, Zapco, PG, always known for clear, clean voices and highs.
That's just one small set of examples. Several other brands for both purpose.
I have all Eclipse for head unit, paragraphic, component speakers and amp for same.
Fosgate amp / speakers for bass.
All just turned 8 years old and have not replaced a single component.
