hifonics amps

Series IX or Series X was the last of the original product.  They were manufactured by Zed Audio.  They have changed hands several times since then.  They are now owned by the Maxxsonics group. You get what you pay for.  They are inexpensive, but when they break, they break BIG.

Well, I think you already know that the JL 1000.1 would be better...but like you said, it's pretty expensive.   Hifonics is a sort of in-between amplifier.  It's not junk like legacy, boss, hitron, pyramid etc., but it's not good like JL, alpine, sundown etc. It's worth noting also that even though JL is a quality manufacturer their stuff tends to be overpriced and some stuff is WAYYY overpriced (1000.1v2 goes for about $800 which is insane to me).

Hifonics tends to be honest with their power ratings and they don't have high failure rates and weird problems like the total junk-brands do; so overall it's an okay inexpensive amplifier.  A brand to consider that is pretty good but not highly-expensive would be Audioque...you could get something that would put out around  1000WRMS@1ohm for under $300 or around 1000Wx1@2ohms for under $450.  If I was in the market for a 1000WRMS amp, I would be expect to spend (and be willing to spend) $300-$500 for a quality unit.
