yup...motorola dati bago naging on-semi, pwede kang gumamit ng MJL21193/MJL21194 kung pang bass....kung full range mas preffered ko yunng MJL1302/MJL3281....

yung leach amp magandang tumunog, sayang naman kung pang bass lang sya....pero pwede.... ;D

all i have done are 250watter leach amps....leach amps are not tiring to listen to even at high volume levels...... ;D

pang mobile ba? yes it is possible to do it, i have asked a friend to design a pcb for me using Leach's doubled barreled amplifier topology using 10 qauds of those ON-Semi devices, that's 40 transistors per channel output.

Two amp3.

the RE has dual2 coils. 
using Y rca to split the two amp3 in mono config.

each amp3 output connected to each coil.

therefore two 10ampere traffos per coil. now how sweet is that.  ;D

for those who doesn't know what RE-xxx.

$1600 or P77k sub

here is a vid sample of 15inch with 6inch excursion.  take note hindi pa ito yung 18inch.

when i was younger, maybe like your age, i used to think that way too.... ;D

if you tell me what size your present transformer is, then i can tell you for sure, normally you can parralel two transformers if you get your phasing correctly.....

the question is, however, why do you want to do it? is one not enough? if you have two of those, you can use two transformers and feed two channels from those two transformers, meaning one transformer for each channel, what i am saying is there is another way...

why the obsession with 20 amps?

one rule of thumb for power transformers used in ss amps is that, you get the biggest one that can fit your chassis....

remember, why commercial amps can get away with smaller and lighter transformers is that, music has a high peak to average ratio as compared to sine waves which is sqaure root of two.....with music it can be as high as ten(10).....

 the transformers used in the Crown PB's are phisically small....
