need help to chose a 4-ch amp for my focals in front and 6x9 eclipses rear

[steelfish 10+ year member]

ok this is my actual set up

in front I have a comp set focal access 165a1 50rms and in the rear 2 6x9 eclipse PS6900 80rms

they are running direct from my HU, a pioneer 3300 with 20rmsx4 but looking for more power to feed those speakers

my budget is $100-$140 top

my car is a compact car (Honda fit), so size and battery saving is important

these are some of the options I have look so far, which one would give more clear sound with my ficals? or if you have another option feel free to post it.

If you care about space use and electrical efficiency, you can skip the Class A/B amplifiers right of bat. Look into Class D amplifiers, my favorite being Alpine PDX and Kenwood XR-4S, but there are some other good ones too. I don't know why people list a long list of features they like... power, size, quality, etc, then drop the budget number... $150 tops! Let me tell you that you usually get what you pay for. I strongly believe in that. If you want something closer to your budget, Alpine MRX-F30 perhaps could work. It's just, it has less power output than the above, but still plenty for most speakers.
