So I've replaced all my speakers in my
Seat Ibiza 2000 TDI 110hp sports edition with the console with a big screen instead of a traditional HU. (all standart from Seat)
My Config:
Front: HSL comp set @75wrms
Rear: 9X6 90wrms
since the original radio couldn't cope with these power speakers (HU is only 4X12wrms) I needed more power. Another Head Unit was not an option.
So I run seperate speaker wires to the booth of the car for the speakers. I disconected the original standard ISO plug from the radio (whick lead to the OEM speakers)
Then I bought a 'naked' ISO speaker plug for my Seat (ask your local car audio dealer)
Then I bought 2 hi level speaker to low level RCA convertors to transfer the speaker level signal to an RCA output.
I've bought the types from Monacor. The are the highes quality. They have a switch on delay circuit. (so no sub woofer thom-thomb) and a sort of noise surpressor integrated sos the sound is very good.
So I soldered the convertors to the naked ISO plug, and plugged it into my HU, than ran double shielded cinck cables to the amps, and so on....
