So I recently purchased 2 Alpine type R 10's and a 2400W RMS Alpine amp and now I can't hear my highs and mids anymore. AT ALL! Even with my EQ bass all the way down and my gain almost all the way down And I have 2 component sets with 100 watts RMS going to each of them. So I got pissed off because I've never had the kind of midrange and highs that Ive wanted so I purchased four pairs of infinity 3-way 6 x 9's I'm going to build a box behind my front seats in between my sub box for my 8 6x9's. Should I make it a ported box or a sealed box. My biggest problem that I've had in the past is there is not enough punchy, punch you in the head and heart midrange. For that reason I was maybe thinking about switching to a sealed box for the 10's as well. Any advice would be greatly appreciated!!!!!!!!!!!!
