arturs

I would think twice before  changing them unless u put same but new ones.

Standart audio output have been tuned in for OEM speakers so unless u can find clean line audio output to connect external amplifier it is pointless to change the speakers 

😞

Gents I have  replaced dash speakers with alpine s40 . And I am very disappointing with new sound. I wish I have never done it. 

And because I have cut the standard speaker plugs off it ill be extremely hard to put the old speakers back. 

I Have 6 speaker system f sport  15  So I don't think I have amplifier at the back  or pre wired cables at the boot to connect one.and make the alpine speakers sound properly. 

Any advice please ?
