PPI PC 1400.2 Amp - Any Good?
A buddy of mine at work has offered me his new PPI PC 1400.2 amp for $20. It hasn't been used and still wrapped in the plastic. He bought it in 2001 but never got around to using it. Is this thing any good? I currently have a MTX Blue Thunder Pro 75X2 amp with one Infinity 10" Reference.
Specs: 200 WRMS x 1 @ 4ohms and 400 WRMS x 1 @ 2ohms
Should I buy this and swap it out? My MTX amp is from 1999.

MTX Amp:
RMS Power measured at 12.5 Volts DC:
37.5 watts x 2 into a 4 ohm load with less than 0.05% THD+N
75 watts x 2 into a 2 ohm load with less than 0.1% THD+N
150 watts bridged into a 4 ohm load with less than 0.1% THD+N
Dynamic Power (IHF-202 standard) measured at 14.4 Volts DC:
90 watts x 2 into a 4 ohm load
165 watts x 2 into a 2 ohm load
325 watts bridged into a 4 ohm load
The sub is 4 ohms so I am running 150 rms now and the PPI is 200 rms.

I guess I don't understand the ratings on the amps. I know that the RMS is the true rating. But does the PPI amp RMS not different at 12.5 and 14.4

Amps have 2 rating systems: Max and RMS
Max is the peak output the amp could achieve in a single burts under perfect conditions with the perfect high-level signal. I said this was a marketing gimmick because a manufacturer can make a 100x2 rms amp put out 1000 watt burst and thereby label the amp "1000 watt amp", but you will never see it put out 1000 watts.
RMS is "root mean square", which is a mathematical formula to figure out the continuous output of typical program data. This is real life output that YOU will see in YOUR car.
Now an amp puts out different power depending on the voltage it is fed from the power source (i.e. car's electrical system). 12 volts is what the battery puts out when the car is not running, 14.4 volts is what a healthy charging system puts out when the car is running. The amp will put out more power at 14.4 than it will at 12 volts. Some manufacturers provide both specs and some don't. You can typically say that an amp will put out about 20% more at 14.4 than it will at 12. so if they give you 1 spec, you can figure out the other. If it doesn't say, you can almost assume the rating is at 14.4.

But if you can buy the PPI for $20, I would buy it and resell on ebay for a profit.

PPI PC series amps are great. That was one series before the PCX series (which is what I have). The PCX were the last generation of good amps from PPI...after that all the amplifiers by DEI and their subsidiaries seemed to converge.
I think the PC series amps were the last series of amps before DEI bought out PPI...when PPI was the sht. Either way..I would def say the PPI should be better than the MTX. PPIs are rated a lot more conservatively.

I agree with all you say, however the MTX amps were bulletproof in that time as well. The MTX is rated higher than the PPI and for subwoofer duties, I would use the MTX. if we were to talk front stage, I would recommend the pure SQ of the PPI.

OP - Buy the amp for $20, I saw an offer above where you could make a profit already!!!

Eclipse XA2000 soon to be changed to either:
- ZED The Deuce = 200x2 into 4 Ohms
or
- ZED Draconia = 70x4 into 4 Ohms active front stage (drivers and xover to be determined)

Alpine IVA-W200 Deck

PPI PCX-2200 (800x1 @ 4 Ohms (or 200x2@4, 400x2@2)
MB Quart PCE216 Components front and back
JL Stealthbox w/ 2 10w3v3s
2 Caps, bluetooth, and all that crap (the bluetooth sucks btw)
I just got the nav unit in the mail from another member...i'm yet to install it.
I like how my setup sounds right now, but I bet the pods would make it sound better.
