Metra Arnés de integración de amplificador 70-2021 para Chevrolet Impala/Monte Carlo 2000-2001

Didn't work for me in a different vehicle, returned. Looked well made.

I use this plug to customize a new pin layout for my 2002 Tahoe. It worked excellent by watching a YouTube video on how to repair these.

This worked perfect for my 2001 monte Carlo SS. The amp was bad. This in short connects the speaker wires instead of going thru the amp. I could have cut the plug and butt ended the wires together but being a SS I wanted to keep it intact. I may replace the amp someday. It would have been neater if it was just a cap that went on the plug that jumped the wires together instead of a loop of wires. But it is what it is. I am happy. Wife is happy she has music, and her chimes are back.

I had to repin the wiring in this for my 2002 Tahoe, but that's easy. This allowed me to easily bypass the factory amplifier in my 2002 Tahoe since I don't feel the need to run new speaker wire for a mild amplifier. In fact, so long as you have 18AWG, you can go to 75 watts per channel and be just fine. After installing this, I'm sure I could have just removed the factory amplifier (and still might, opting to use that space for a small aftermarket amplifier). I left the amp in for now just in case removing it would throw a code. There's a second connector on it I haven't removed.

Hmm...I'm not so sure about how this thing is wired up. I have a 2000 Impala and when I installed this it reversed the fader on my stereo. I have searched a lot online for the suggested way to jump the wires on my factory amp. What I came up with is the same wiring everyone seems to be using for their older Tahoes; the wiring in the photo someone attached to a review. So I rewired this thing and lo and behold the fader is now correct. I was also concerned that using this thing the way it was wired originally that the polarity of the speakers was reversed. It sounded bad. With all that being said, having this installed makes my aftermarket radio sound worse not better. I don't plan on using it unless I come up with a definitive reason why I should use it. However, if your factory amp is …

I have a 2001 monte carlo ss with the radio that uses the external amplifier. My radio lost all sound output as well as no chime sound for door ajar with key in ignition or for warning lights coming on etc. I verified the radio output, verified power and ground at the external amp and determined the amp was faulty. I did some research and found its not actually an amplifier that gets a line level input but a power booster that receives a speaker level input and just boosts the signal a little. The amps/power boosters are very pricey and this was a great alternative to fix my no sound problem. It just runs the speaker inputs from the radio up front directly to the outputs bypassing the amp. Not as loud as it was before but still sounds good and loud enough to listen with the windows down …

The speaker amplifier on my Chevy Suburban non-Bose radio system failed. I found that the factory amplifier is no longer available but discovered online that the amplifier can be bypassed allowing the radio to communicate directly with the speakers. The online instructions noted to use a Metra 70-2002 but not finding one online I ordered the 70-2021. It is a perfect fit but the jumpers need to be changed, a simply process. The pins on the connector are easily removed using a small screw drive or a paper clip. Correct wiring is found online (pin 1 to 9, 2 to 10, 3 to 11, 4 to 12 for both the "A" and "B" rows). Plug it into the radio harness and the front and rear speakers work fine. This does not power the sub-woofer speaker in the rear of the vehicle but does what I wanted - lets me …

After some experimenting with wiring combination I was able to make this work on my 2001 Suburban. The factory amp had decided to die. I was really not too optimistic as this product has mixed reviews. I was able to find a decent wiring diagram and figured out the sequence. My biggest surprise is that the factory Onstar actually still works after doing this. Unless you own the impala that this harness fits or your very tech savvy I wouldn't recommend this route for you though. There are services that will repair your factory amp advertised on E-B-A-Y. Also I wan't able to maintain the factory sub in the bank with this adaptor. Not sure I really need a sub. Im going to replace all the speakers with decent aftermarket ones as most of mine are blown anyways. With the help of the Metra …
