how many watts will i really get?

Im torn between the kicker 350.4 and 650.4. for some retarded reason there is nothing inbetween. this would make sense cause then it would match the speakers they sell.

the 350.4 is rated at 60w/channel @4

the 650.4 is rated at 120w/channel @4

120 would be ok for the cdts, but maybe not the kickers or if i keep the infinitys. 60 doesnt seem to be much at all. plus on our spec tag at work it says only 45w/channel @4. this sucks, but i dont want to spend more if i dont need to or if I will blow out my speakers.

a question I have is if you put a 45-60w per speaker will it still optimize the SQ, but just at a lower volume? or will the 100-120w make it actualy sound better in SQ? or will it just get twice as loud. from listening to the 350 and mtx 4004 at work, the sound quality is great on them even at that level.

theres a lot of things to juge on how much power you'll really need to send to your mid/high's. imaging, road noise, how loud sub's are etc, if you feel you need 120 watts to them then go for it, but if not save a few bucks and go for the smaller amp.

It really comes down to whether or not you need to extra power to obtain the volume level you desire.

My personal rule of thumb is to purchase as much power as possible. You can always turn it down if it's too much (via the gain, level setting feature on the headunit, etc). But if you have too little...you're up shits creek.....

id say the 120w, like above post said u could always turn it down if its 2 much power, but u cant really turn it up (with a clean signal) if u need more
