I've read another person who has added a sub and tweeters and got past this with opposite phase wiring, but don't know if anyone has attempted external amp driving new (full range) speakers. If so how did you defeat the system fake engine sounds from distorting your signal?
and to anyone with a US I4 and planning on adding external amps just fair warning as of now there's no information on whether or not it's an external module like a SoundAktor where we can pull the fuse. The issue is this signal is so strong it will render your new sub useless as the noise just rumbles the sub at very high volume, same with door panel speakers.
