Sound Storm Laboratories EV400.4 Evolution 400 W, 4 Channel, 2 to 8 Ohm Stable Class A/B, Full Range Car Amplifier, Black

can u still connect this amp if u only have one set of rca in the back of head unit ?

Can the 400 ev 4 channel push 4 6.5

just need around 45 more watts to ONLY my highs mainly, but to Mids as well- anyone with this amp think it will do what i want???

Say i wanted to hook this to four 5x7, would it sound any better than the jvc kd-s79bt radio unit i have? It's only 5 more rms per speaker
