i'm buying the same brand i did last time, crunch

Find out the ratings on your speakers

# Power Handling:

* Peak: 240 watts per pair / 120 watts each
* RMS: 120 watts per pair / 60 watts each
for 6.5's

# Power Handling:

* Peak: 120 watts per pair / 60 watts each
* RMS: 60 watts per pair / 30 watts each
for 4's

Now find an amp with similar ratings...

but have the amp to be higher, but have the input turned down correct

If it has to be I guess, can't find one closer?

the 600 watt is->

# RMS Power Rating:

* 4 ohms: 37.5 watts x 4 chan.
* 2 ohms: 75 watts x 4 chan.
* Bridged, 4 ohms: 150 watts x 2 chan.

# MAX Power Rating (14.4V):

* 4 ohms: 75 watts x 4 chan.
* 2 ohms: 150 watts x 4 chan.
* Bridged, 4 ohms: 300 watts x 2 chan.

I wouldnt recommend a higher rated amp than what you need.

so you wouldn't suggest that i use the 600 watt 4-channel amp, that it isnt that over powered

actually nvm, i found a RFG 300 watt that i can use
