2003 g35 coupe HU install
I'm still a tiny bit confused.
I have a 2003 G35 coupe with the Bose package. My CD player went out, so I decided to get the Pioneer AVH-X5600BHS. I'm keeping the same speakers, not adding a sub nor an external amp, ONLY replacing the head unit. I already got the antenna adapter and the Metra Doubledin installation kit. But I went to best but and they told me I needed and amp interface (model ISVE61). Just wanted to know what I should get, whether it's that one or the PAC ROEM-NIS2? AND which wire harness I should get?

It pretty much converts signals from the DDin for your Bose amp to listen. On the device there is a + and - for each speaker. The other Metra piece (oddly also called 7551) connects aftermarket wires directly to your aftermarket radio without splicing of factory plug.

You can look up my history on my posts with that subject. Long story short, the lax quality controls and inconsistency with Bose products means once in a while, it works fine without the ROEM. If you get the harness free (like I did) and want to give it a try, go ahead. But there were many people who claimed to have it connected exactly like that and it didn't work at all, so rather than try and troubleshoot why they didn't get the same results, a $35-40 ROEM-NIS2 is money well spent to have something that's worked for 99% of people, rather than something that works for, I dunno, 20%?
There's a couple of reason I still leave that video up:
1) To prove that it *can* work fine to those who doubted me.![Icon38](https://g35driver.com/forums/images/smilies/icon38.gif)
2) To show the way it should be connected if you want any chance of it working right.
Anyway, to answer the original question, the ISVE61 is supposedly equivalent to the ROEM-NIS2, and it's what Best Buy uses. Considering there's been relatively few complaints about volume levels by people blaming best buy for their installation, I can only assume it has a pretty good success rating. However, the goal of the list is to keep things simple and cheap. Listing equivalent options that are more expensive to purchase (like the ISVE61) only serve to complicate things, so they won't be included in the list.
So yes when keeping Bose amplifier:
Aftermarket Headunit Harness (speaker-level output wires) -> PAC ROEM-NIS2 -> Factory OEM Radio Harness

Hey Wrathernaut, you wouldn't happen to be able to install a TransGo kit would you? Looking to see what I can get installed when I make the trip. Probably going to grab some new front speakers, possibly an amp and a subwoofer also. Any recommendations for those by the way? Looking to upgrade to the bare minimum, nothing special, just something that won't pop when I turn up the volume on my DD ![Icon17](https://g35driver.com/forums/images/smilies/icon17.gif)
Thanks man!

At how good they are for the price, I can't really recommend anything other than the Image Dynamics CTX65-CS. I've got them in my wife's car, and used them in Tr0uble's car too if you want a second opinion on them without any subwoofer. I can't remember which amp we used on his, but I've got the RF P300-2 running in my wife's and have been very happy with it.
Subwoofer, I'd say sundown SA-10. You'll need to get another amp for that, again, I've been happy with the RF amps I've used, so: RF P500 amp.
You'll need a dual-amp wiring kit for something like that.
Oh yeah, you'll also want to pick up some speaker spacers. zenclosures used to make some good ones, but they're not on the site - http://www.zenclosures.com/Speaker-Spacers-s/36.htm - you may want to try calling them. It took me like an hour or so to make them last time.

Nope, transgo kit is more than I can handle in my garage.

Thanks a lot for all the help and inputs, this is the only place I could find anything about this.
I have a 2006 G35 Coupe, I will be replacing the HU with a Pioneer AVH-4000NEX, adding a sub and sub AMP, I'm trying to keep my factory AMP for surrounding speakers from once they sound good with the new HU, if not I'll go ahead and replace the factory AMP also.
I have read your post and you said if I want to keep my factory AMP I should buy the PAC REOM-NIS2,
but when I checked eBay for it they said it's not compatible with my car.
Can it still work?
Is there another one for my car?
If I should decide to change the factory AMP can I still use it for the new (JL audio 4CH)AMP or should I also buy the METRA 70-7550-1?
