Yeah, get a good head unit, and I personally think the best head unit you can get are alpines, but again, that is IMHO. And I also go with JL Audio's if you upgrade anything else in the car.... But, for now, if that is all you want to do, I think you should get a Alpine....

Raiders -- Are you referring to routine service reminders that can be reset through some GM factory radios? These commonly have a secondary procedure that doesn't evolve the radio.

You'd have to check a shop manual for the Impala; it will have the details you're looking for.

Sorry for the delayed response.

Hi .I have a 2003 Chevy Impala. If someone can please tell a little about sensor manageability functions thru radio.

Well, it turns out there's something glitchy happening (informed technical analysis) with the speaker demo video I'm trying to post. It was an attempt to capture the sonic difference between the front (aftermarket) and rear (factory) speakers. I think it did so admirably, but you'll just have to take my word for it for the time being. Hopefully, we'll re-shoot and post something in the not-too-distant future.

Next step: amplifiers (and probably more Dynamat).

Hi Nelson,

I meant that I connected the blue wire to the corresponding wire on the harness we have for the 2002 Yukon:

I have a 2001 Yukon and im running into the same problem with the radio connections. you said "connected the blue turn-on wire and everything worked." just wondering what did you connect the blue wire too?

thanks for any help

Thanks, TH.

No doubt that bypassing would help -- it would eliminate any distortion introduced by the second amp in the chain (the factory amp) and I would be powering the speakers with a better, cleaner, more powerful amp (the 9887's internal amp) -- as you say. However since this is just a temporary situation, I hadn't planned to do it.

Hmmm... maybe it's worth trying and reporting on?

I'm enjoying reading the progress.

This comment probably should have gone after Part 2, but I just read it now.

I'm not sure how the factory subwoofer comes into the equation, but from what I read, you are using the 9887 through a factory amp to the factory speakers.

This is fine for people who are new to car audio (and I don't mean that personally as a reflection on you, so don't interpret it that way), but ....

The factory amp is usually set up so that you can turn the volume all the way up and not worry about blowing the cheap factory speakers. IOW, it is probably a lot less power than the 17W or so that the 9887 puts out. For people that don't want to upgrade their speakers and don't want to risk damaging them, this is great, but you are probably actually REDUCING the power output of the 9887 using this method. If you could bypass (at least the non-subwoofer portion of) the factory amp and run the stock speakers directly off the 9887, you would probably see a further improvement in sound before even swapping out the speakers.

Thanks for the catch, REO.

We do have the PXA-H100 in stock.
