have no idea where should I ask this question, found some nissan infiniti forum, the J30 always in "other infiniti" section and nobody talk there

ok btw, question about install aftermarket head unit, cause the J30 use BOSE system, AMPs on all speakers, I am not sure how to install a aftermarket cd player??? got wire diagram from ALLDATA, looks intricacy.

any instruction???
thx

 

The factory system probably just sent line level signals to each speaker amp. If your new head unit can do this, then that's what I'd suggest, otherwise, simply run new wires from the head unit to each speaker, and remove the old amps. You don't want any splices between the head unit and the speaker (unless you like crappy audio), so you don't want to jury-rig it.

You might be able to use the existing wires, but I'd replace the factory speaker wire with something like 16 gauge if you are going to the trouble to replace the factory head unit. A 100' spool is only ~$12, so there is no reason not to replace the wire. I'd solder the new wire onto the speaker leads if it were me.

 

it's not that easy, If it's only sent the signals to amps, I could do it. but from the head unit, it sent signals to some other controller or something like that, then there has another swithcing unit.............damn I don't even know how to explan this, the wire diagram looks really intricacy.
I'll take a pic soon......

 

j30 is a great daily driver, i drove one for a friend as a dd a couple times. Horrible resale value/marketing though

 

thx, I got this J30t as a gift casue it got accident, I bought another J30 complete car to be a part car and fixed this one. I am tring to install some other styff so I need a cd player with AUDIO IN, if not I won't change the stock BOSE one, that one is great enough for me.
this car will be my daily driver, and I will use my s2k to be a track car

btw here's the diagram, plz help..:

 

There are premium sound interfaces available. IMO, they are mediocre at best, but they work and save a lot of time and money if the factory speakers and amps are all working properly.

Otherwise, you may need to rewire and replace the speakers. On a lot of Bose car systems, they use speakers with impedences < 4 ohms which may not work with an aftermarket radio.

 

how about the tweeter? will they work with aftermarket system?
