I have a BD1000a1 (fosgate) amp. Could I use this for midbass. Would mono for midbass be ok? I'd run it from 90hz to 250hz.

cheers

 

NO, do not use it for midbass.

 

while some class D amp are cleaner than others over 100hz, my bd1000a1 was really not clean and was lacking SQ big time over 100hz when I powered my cdt EF-8 with them. Bd1000a1 have a good resale value, you could easily sell it and get a high power AB-class amp

 

I would take a $200 class a/b over a $1500 class D for midbass anyday.

 

I'm running two bostonpro's 6.5's in each door. Currently using an 800a4. The 6's are 3ohm each - 1.5 ohm parallel. What amp would be stable at 1.5ohm and push 300+ watts?

cheers

 

The elemental Design 9.2X is designed to be 3ohm stable bridged, so 1.5ohm per channel. it push 300w rms @2ohm x2, and approx 350w rms @1.5ohm per channel.

I currently use a Nine.2 on my cdt hd-52 components and i'm very satisfied with the SQ and power. It sound better than Kicker KX or PhoenixGold XS

The 800a4 should be plenty of power to pump your speakers...they are only 6" so it only takes about 100-150 watts RMS to get them up to speed quickly.
