Hey

i need help choosing between these 2 budget 4 channel amps: the ppi 900.4 and nvx jad 800.4 amp

both do around the same numbers at 14.4 V, but the NVX amp was dynoed but they only dynoed it using 2 channels out of the 4 and it gave a much higher number than it would if they tested it using all 4 channels.. Not sure if the PPI was rated using 2 channels or 4.. but im pretty sure they dynoed it using all 4 channels as the numbers seem more accurate.

having said that and not knowing exactly what the NVX amp does with all 4 channels @ 4ohms.. which amp do you guys recommend?

I have heard they are all the same inside/use the same boards etc.. not sure if its true or not..

the PPI is 20 bucks cheaper as well..

so , anyone that has ever used these amps have any feedback or recommendation please let me know. Thanks

heres the link for the dyno for the NVX 4 channel (they did the test using only 2 channels so their numbers are not accurate for a 4 chan load)

hmmm.. i dont think there is any.. other than aesthetics.. i believe its the same board? same performance?

I have the JAD 800.4 and love it, you wouldn't be disappointed.

ok i went ahead with the NVX JAD.. my research shows that they are basically the same amp.. there are several companies that have all cloned this amp.. not sure who the originator was , i think it was PPI.
