installing amplifier

[wildmax]

Hello guys

i have Auris 2014 hybrid , and i want install/replace audio system ( replace Speakers add sub and amp ) but keep original multimedia center , can i connect amplifier to original Toyota audio system amplifier? or i must replace original audio system to connect amp

I am in the middle of replacing door Speakers, front ones done but new rear door Speakers still on the desk at the work...

But , i was wondering(and still am) also installing amp, i ended up thinking that if i install amp, i will put for example Alpine MRV-F300 where there is speaker high level input with auto turn on signal from that also. That way it would be easy to keep original audio system. One another alternative is to use line converter what turns stock audio line to rca level output and you can use what ever amp you like.

 

just remember that inverter can deliver 100A to 12V line and that there is about 300w worth left after all nessesary systems. So avoid going over that with sub amp.

so original  system not have amp  connection ....

i has  alphasonik PMZ6004a 4 channel amp .

Alpine SPG-17cs component .

rear Speakers i am going remove at all from the doors and going install Alpine SXE-6925 on the dash .

and subwoofer Rockford  (not remember his model , he coming from my car that was before auris ).

install all that with convertor you loosing sound quality  , I thought we have another alternative better Toyota system that original that has connection to amp , or some audio system like
