Yup the last generation x series of amps were quickly phased out, they had lots of overheating issues due to using surface mount mosfets cooled by thick thermal pads, this turned out to be insufficient cooling so alpine went back to old school descrete designs, the surface mount mosfets were a ease of manufacture and cheaper to assemble with lighter heatsinks but overheating became a big issue, they really did push the thermal envelope with the x series, alpine learned there lesson and went back to the older design ❤ i can confirm from the guts of the 150 r2 model that they are built heavy duty with plenty of traditional clamping discrete devices both on the the power supply and output devices, although they decided to use lelon capacitors inside instead of traditionally nichicon or chemicon or nippon or Panasonic caps, how that affects longevity who knows, the heatsink are beefy solid, although I don’t like the gimmicky front panel being screwed on, it is made of aluminum but don’t know why they could have used some type of recessed adjustment knobs instead of metal having a cover and it being screwed on with four screws isn’t as easy to access
@saycheese2162 I ended up purchasing the Alpine R2-A60F R-Series 4-Channel Amplifier - 116W per channel (per the birth certificate). Running S-S65 6.5 80W in the front & SPE-6000 6.5 60W in the rear & it sounds FANTASTIC. (1997 Camaro Z28 Convertible.)
@realKevinRichter how did it turn out I'm thinking of getting the four Chanel just waiting for more reviews I like the look of them. Need to upgrade the old s type from years ago
The birth sheet shows for a 2 Ohm load, not 4. I've seen these dyno 4 Ohm up around 140w. But, it's not more impressive than a Kenwood Excelon Reference XR401-4 or a Rockford Power TM400X4ad that has a real birth sheet showing all testing done, both 2 Ohm and 4 Ohm, THD, etc. Not just some hand written note in the box. That Kenwood is way underrated, and I've seen dynos pushing over 150w X 4 @ 4 Ohm and about 225w X 4 @ 2 Ohm, which is just nuts.
The previous generation has overheating issues that I'm dealing with now and the new generation doesn't have any ventilation holes nor does it have cooling fans

The best kind in my life
I hear Alpiine from twenty year

whats the difference between the R2-A75M and the S2-A60M besides the RMS wattage?
Can I run S-Series 80w RMS Speakers with the R-Series amp or nah?
Yes

@@abe4781 It’s awesome.
Very cool amps!!
Has the Alpine Type x series being dropped out of the Alpine line and replaced with status
Hey Rockford Fosgate gives a BC with amps to
Can I use 0 Gauge Cabel directly on amplifier?
I don’t see why not. I use 0 gauge for remote turn on.

R-A75M and R2-A75M are same or different?
R2-a75m is smaller
Why would they be the same

For 1500 amp alpine …2 12 type r 1242d is to much power??
They didn’t write anything in my verification certificate.
