[QUOTE="jjsowa, post: 8836631, member: 688572"] I bought a semi truck with a custom audio setup. I wanted the factory head unit back (has engine gages and navigation for the truck. Peterbilt SmartNav) so I installed a line output converter (AudioControl LC8) I wanted the LC7i but that’s what my local shop had in stock and I was impatient. Hooked everything up and it’s working. However the subs are not hitting very hard. I tried to turn up the gain on the subs and when I do they start working like they should but my main amp shuts down. The red protect light does not turn on but the blue light goes out. All the while the sub amp keeps going. I’m just confused because they are separate amps. Why is one amp having an effect on the other. I was thinking it might be a power issue but it’s running on 7 batteries so that seems unlikely. I can run each one individually and they work great. It’s only when I try to run both with the gain on the subs turned up that it shuts the other amp down. The mono block amp for the subs is the DS18 candy x1b and the main amp is a Taramps TS2000x4. I’ll spec the speakers if needed but like I said they work great by themselves so I can’t see it being a speaker problem. But I have no experience with this stuff so maybe I’m wrong. Note: I have no idea if this problem existed before because the previous owner who had the system installed had destroyed the rcas running to the back. He ran them right through the bottom door trim and they got pinched every time he got in the vehicle. I wanted the factory head unit back so I saw no point in running new rcas if I had to install a line out converter. [/QUOTE]
