[QUOTE="Doxquzme, post: 8866932, member: 689267"] Hate to say it, driver placement is amiss. Right beside, preferably above and below like this: [ATTACH type="full"]55569[/ATTACH] You have really broken up the stage locating them like that. The other issue one runs into on the old jalopies is that the doors have a lot less airspace behind them, this reduces any midbass low end extension one might get in a bigger door cavity. What happens when you put these that far apart is the crossover point (wanna say around 2200-2500?) is diminished as the tweeter and midbass driver are not close enough to assist in bumping, normally suming in that narrow passband range between the high end of the midbass and the low end where the tweeter picks up. More like two speakers doing their own thing instead of two speakers acting like one. Bridge the kenwood to the focals if you haven't already, that gives you 150x2 to the focals, add the alpine and play with positioning to get the most from is. Another option depending on room would be to get one of these: [URL unfurl="true"]https://www.ebay.com/itm/224340877451?mkcid=1&mkrid=711-53200-19255-0&siteid=0&customid=link&campid=5335951755&toolid=20001&mkevt=1[/URL] and one of these: [MEDIA=amazon]B01E5TO9TY[/MEDIA] Perfect tiny little amplifier that puts out about 250 at 4 ohms. [ATTACH type="full" width="507px"]55570[/ATTACH] That is slightly more $$ than the Alpine powered sub, but not by much and would be a perfect compliment to the focals up front. [/QUOTE]
