hi all,

i am new to car audio system, hope you guys can give me some advice on it. thanks..current i am using a old Alpine 9815 Head-Unit, had installed a SPX-177R in front, a rear SPR-17LS, but what kind of Amplifier, should i go with it? please advice. Thanks. I am driving a Toyota Corolla year 2002. and i am looking for great SQ.

Alpine MRV-F545 a great four channel with tons of power....and with the new Alpine line up coming out you could probably score a deal on one!

yeah, actually i also looking at MRV-F545, should i just go for it, or i should wait for the new PDX series? what is the different between those 2 4 channel amp?

the pdx is all digital amps but power for the size they look pretty cool i havent heard them yet but acording to the guys at alpine (jason kimmer and steve brown) they told me that they were as good or even beter sounding than a f#1 alpine amplifier.... ill wait to see if that is true but all in all bang for the buck the 545 is a dam good amp

i am skeptical of the new pdx amps because of the processing of the signal that is neccessary to achieve what they have with the new pdx. having said that i wont discount it untill i hear them but to say they are a good as an f#1 amp is a bold statement considering the mrvf900 amp is a pure gain stage amp with no direct signal preocessing, aka crossover and things like that. maybe at 120k with the window open you couldnt tell the difference but in critical listening evaluations, we'll see. i have sold and installed a shitload of 545's and they are stellar and would work very well for you. and for the record its jason kermerer not kimmer

sorry dave

no problem, have a good time at korn ya fags
