[QUOTE="Coupe, post: 4893474, member: 599112"] I have a Alpine MRD-F752. I bought it on Ebay many years ago but never had a build. It is a 5 Channel 1 Amp Solution. This thing has crazy power. Just to give you an idea it is rated at 75x4 @ 4 Ohms and 250x1 @ 4 Ohms. This is the actual ratings most of them put out! [IMG]http://ampguts.realmofexcursion.com/Alpine_MRD-F752/outside4.jpg[/IMG] Anyway. I bought a set of Infinity Kappa 6 x 9 for the back and a Infinity Kappa Perfect 5 1/4 component for the front. The 6 x 9 were 2 ohms but they were supposed to take 120 watts which is clearly right around the amp power (which is 100 watts @ 2 ohm spec - translate to maybe 120-125 watts). The front Perfects were 110 watts, which also was more than the amp was supposed to put out even with the fact that the amp powers more than its specs. Needless to say this Amp TORE through all 4 speakers and blew a hole in the rubber of my Eclipse Aluminum 12" sub (although that was a mounting problem where the bass made the box jump and fall on its front) I spoke too much, I realize also I might have to under power my amp so I do not blow my speakers in the future. (ugh and my gain was about 80% not full blast) If you guys could help with recommendations for a front 5 1/4 component and a rear 6 x 9 or should I get the brackets and put rear 6 1/4 or go full 6 1/4 component. My price limit is approximately $400, unless persuaded [IMG]//content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif[/IMG] [/QUOTE]
