IF I had the money those subwoofers would be MINE! I had a set of those in a '96 Escort Hatchback that ended up cracking the back window on while driving down the road combined with one of those old Phoenix Gold M amplifiers in a custom box.
Man if only you could wait till February or March I could save up,lol
lol nah I just got a new mono block amplifier. If anything I would go with those subwoofers as I plan on buying a G-Body '84 Olds Cutlass in the next 4 years and will do nothing but old school stuff in it like those kinds of subs. Hoping to find a Clarion Pro-Audio CD deck from back then as well to put in it. I still kick myself for selling that beauty of a deck. It was in that Escort GT. I really should have kept all that stuff from back then I would be sitting on a pile of stuff that is worth money and would be useful in said build for that Cutlass.
If someone wanted to do a 3-way active front stage + subs, had a DSP, and didn’t care about L/R imaging on their front midbass they could do the following:
Parallel 4-ohm midbass woofers (500x1) on the 250.1; run 2-ohm mids (100x2) and 4-ohm tweets (50x2) on the 400.4; and run the sub stage on the 800a2 with both end caps. Just like the mounting configuration in the picture with a PBLink connecting the 250.1 and 400.4.
Someone who lives in FL should do that so I can drive to meet them and drool over their setup.
