Options, 4 channel amp with a lot of crossover options

[aculous]

Alright so I was going to try and do a active setup using my 80prs but for my application it ain't go'in work. SO! new idea.

Run active for 6 speakers on (2) separate 4 channel amps.

I was looking at SoundQubed and American Bass so far. But dunno if there would be some better options out there under 350$ if I can do it. I am going to buy two of them so I am trying to not break the bank. Considering I already am spending double what I thought on my build to do it right.

Reqs:

4 channel

Full Range

wide crossover options as in hi/low/bandpass

under $350

Looking for low distortion as well not a ton of amps list it in their specs
