Bypassed amp, lost sub and rear speakers

[WeekendPlinker]

Just that. Installed a new head unit and amp for my mids and highs.
Bypassed the amp behind the glove box (non Bose) and lost my rear tweeters and sub.

All the outputs from the radio are capped. Should I hook them up to get the rear sound back?

Yes. Those items are run from the factory amp. By bypassing it the amp is no longer receiving signal.

If I hook up the outputs from the radio to the harness will that remedy the problem?

Since those speakers are still hooked up to the factory amp, connect the blue remote turn on wire from the head unit to the pink wire on the factory harness. This will only turn on the amp, but the speakers will not be getting any music from the headunit. If your are only using headunit power, which is usually not that much, you may want to consider using the factory amp so you have all you speakers. It may sound good enough for you.

I just installed a new head unit 2 days ago, I hooked everything up from new head unit to the factory plug, powered it up and I didn't have any sound. I had to do the same thing with the pink wire. My tahoe is missing the sub so all i have are mids and highs and yes it sounds like crap. lol This will change next week.
