I have a 10" kicker cvx on 400 watts and my 2 way co-ax speakers on 35 watts each. I've been lacking mid bass bad. Only way I can describe it is if you listen to the song "Still in this *****" by B.o.B. and T.I. the mid bass to bass drop is pretty dramatic. It sounds like a puff puff BOOOOOOM!! The amp clips with bass up to high so I keep the eq at -1 for 100 hz and when I am really bumping have to turn it to -2 to avoid clipping. With my old 4 channel amp I had the sub lpf at 120 hz and speakers above that and it sounded pretty good except that the speaker amp was trash and whiny. The new amp has an hpf of 80 hz and is non-adjustable, so I set it up with 80 hz and above to speakers and sub lpf at 85 hz (through deck). I've been thinking of how to resolve this lack of midbass issue that I am having and my idea is to set up filter at 100 hz. I can exchange my old mtx amp for a new model for less than $100 and would give at least 10 more watts to the speakers and have an adjustable hpf. Well I wanted to try before I buy and good thing I did. I set the amp lpf to 100 hz and turned the decks up to 120 hz (amp would override deck correct?) to let the sub take all the way up to 100 and although having some crossover between speaker and amp, get to hear more of the higher bass notes. Hey it is a 10 btw so it should do pretty good up to 100 hz right? Wrong. I don't know if it was just my interpretation, but my sub did not sound near as good. Can 15 hz really take that much quality out of the sub? Was it the crossover between sub and speakers that made it sound not as good?
So I guess overall question is, is should I invest $100 for a new amp to get 10+ watts to each speaker?
Would this be enough power to get more midbass from the speakers?
If I do should I set filters at 100 hz or is 85 hz better for a 10" sub set-up?
