Default about "1000W" car amplifier

hii all....i want to tray something with this car amp...

i have car amp in my home..... a new amp.....
"1000w"

the amp build from 8 transistors - 2sc5198/a1941 (100W-10A)
8 transistors driver - 2sc2690A/1220A (20W 0.5A)
30 transistors signal - 2sc1815/1015
6 opamp - ne5532P - (bass crossover (normal / 250-40hz))
4 caps of 35V-2200uf

2 transistors for 1 channel (4 channels - 2 bridges )

if u in a 12V to the amp it will out (in the amp) 23V+/-
15V 28V+/-
17V 32V+/-

minimum for 1 channel is 2 ohm. for bridge 4 ohm minimum.
the amp hottttt !!! with full power audio if connect to him 2 subs (900W max - 4 ohm ) in bridge....

the amp out 60W RMS in 4 ohm for 1 channel (12V in)
= 120W RMS in 2 ohm stereo
= 240W RMS in 4 ohm bridge

now i want to change the amp...

to connect a power supply - 25~0~25VAC 1000VA
- to home use
- to add 47000uf - 50V for best bass....

to change the transistors to 24 of 2sc5200/1943
- not hot ani more
- to get high power from bridge 2 ohm subs (2ohm bridge =480WRMS)


it will be good?

Looks like a pos amplifier. Have you actualy finished a hi power amplifier. i have seen so many of your posts of these amplifiers. and lots of ideas but till this day see no sucsess. why not just buy a dj amp insted of building one. buying a dj amp makes way more sence any way..

Let's see now, get rid of monitor and keybord, replace those
crappy speakers with a pair of B&W 805, or whatever your
preference is, and replace the PC with an Aleph X. Now it is
starting to look like something.
