Default Alpine MRP-M450

Got this amp from a friend.

It looks very cheap and poorly built, so I dont want to spend alot of time on it.

He replaced the outputs before and said it would play fine in stereo but when you bridged it the outputs would burn up.

I got it in pieces and the outputs are missing.

I need to know what outputs it had.

Q110D
Q112D
Q110C
Q112C

He "thinks" it had like TIP41C and TIP42C but cant remember nor can he remember the order they go in.

Anyone?

Are you sure that's an alpine? It looks like a Boss or something similar.

The M450 was a class D amp.

Came with an Alpine heat sink, bottom cover with Alpine sticker, and endplates. Everything lines up perfect.

Says Alpine V-Power 2/1 channel power amplifier. 1000 watt MRP-M450

Heres a pic of the heat sink.

Maybe someone was putting Boss amps in Alpine heat sinks and ripping people off?

Board number is 06-020162-1100
REV: 1.0

Yep. That's a fake. The M in M450 would mean 'mono'. THIS is an M450.

If the clamps will allow it, I'd suggest using the wider holes in the board and using FJA4213s and FJA4313s.

The NPN output would have its center leg connected to the center leg of the positive rectifier.
