i just like the old punch series amps idk but im old school went it comes to R/F

i remember when i was younger my older sisters B/F had 2 Rockford Series 1 Punch 10'* in a 5th order box with a punch 45 man that slammed

i had 2 punch 250'* to date i would have to say that those are the amps a like the most

I have an Alpine 4-channel amp in my Bonneville and it sounds fantastic. I also give high marks to Eclipse, which we put in my wife'* older Grand Prix.

Eclipse makes great amps and even better headunits.

the punch 45 was one of the best amps ever made

that was a great amp, i had one and then stepped up to the punch 60. that was a while ago. wish i had held on to them.

i have been looking at the Sony XM-SD46X. http://www.crutchfield.com/*-jHdSC0A...0&I=158XMSD46X

i have the sony xm-sd51x running a single kicker 12" comp in a ported box and i am really happy with the performance. i am thinking about staying with the sony brand just to keep things matching. but i have also been looking at the RF P4004, and the alpine mrp-f450.

does anybody know the signal to noise ratio and THD is for the RF, i looked on the website but didn't see anything.

thanks for all the input.
