Hi guys, I just got into ice recently with my father's old school stuff. My father has an Orion 250sx 2 channel amp which I've installed recently to my stock head unit car ( ranger t6) front speakers of lightning audio component speaker. And now i have two Apache 600w and 400w amps laying around with a pair of Blaupunkt Velocity VPC10D woofer. While googling for some idea to mount the woofer, I found a way to mount the woofer under the back seat ( undertray storage) and i started to do my own fibreglass woofer box. The problem with it is how do i connect my sub to the head unit when I don't want to use a preamp. Another problem is where, I'm not sure which amp I should use to power the sub because I can't find any details for the Apache Amps online.

Okay, i’ll try and see, all the stuff been left at the side since more than 10 years.

The Orion doesn’t have any rca output 😢😢
