As far as output, reliability, and sound quality how do they compare to alpine, rd, or whatever other good amp brand. I know their comp subs are great but I haven't delt with any of their other products...
PR Series Mono amp- loved all 4 of mine... Strong for price M Class Mono- High power at 2 ohm stable. Strong. Large footprint, power-hungry, inefficient.. I personally would have no problem running any of their mono amps.... That is all I can comment on...
likely to be the new PR1000D.. They are proud of the addition of the cooling fans.. I ran the older ones and can pick them up for $250 BNIB in Houston... check ebay.... they sshould have new and refurbished cheaper than your local dealer.. IIRC Crossfire and Memphis are made by same manufacturer
The 4kw does seem like a current hog but i have no experience with it.
The mcd1000 is actually quite efficient as well as thier m-class a/b amps. With these i do have experience so i'm not just repeating what i have read on other forums. But i do agree they are somewhat pricey.
i've owned 2 of the MCD1000s 1100 watts at 1 ohm they are underrated and very efficient and the black pearl finish on it is just beautiful loved it and it was tiny for a 1k watt amp
ive had the ST-1500 and the ST-1000 both were power hogs. Happy was the day I sold them was I. Also, they always made my subs sound "muddy" if thats possible.
