RD45 Amp Questions

[cristiantoni9]

Hello and good day, sorry for reviving this old tread but this is beautiful
I got a question to ask if possible
I got a C4 Coupe with JBL Hi-Fi system fitted from the factory, with RD45 unit, bluetooth, usb and aux (i got it from ali express, works like a charm)
I swapped the front speakers with a better ones, I have a little bit of better sound but not really what I expected (as I guess they have a crossover point from the factory amp/eq)
I see here that you also fitted another JBL AMP other than the factory one
Is it somehow possible to amp sepparately the front speakers while retaining all the factory settings?
If yes, from where can I get audio signal(full range? thinking about getting audio signal from RD45 before going into the factory amp? because I think the audio signal to the front speakers reaches with freq cut)
Please help me with a suggestion if possible, thank you
