Metra 70-1728 Amp Bypass Harness

Easy to hook up! Sound coming from the actual head unit instead of the factory amp makes a huge improvement! I'm even hearing sounds I haven't heard before! Especially sounds coming from the tweeters!

As usual, Crutchfield delivers on customer service and pricing. The bypass harness had great instructions and was super easy to wire. Had the head unit installed and the amp bypassed in less than thirty minutes.

Just like all the harnesses sold by Crutchfield it was a perfect match! And regardless of where the stock car amp is located you will have plenty of wire length to reach it in order to bypass it. I believe I had about 6 feet of wire I trimmed off when I used it on my civic. It's better to have too much than not enough if you ask me. If you need to bypass your amp this is the harness I recommend!

Perfect fit!

Great adaptor! I was confused on why is was so long but then I understood you can actually run the wires all the way to the back to a amp. Perfect fit!

Fried stock amp fix!

This works, Installation was easier than I thought, of course thanks to Crutchfield team. The reason I needed this was because the factory amplifier was fried and all my speakers were not working so with this I bypassed the amp and then presto! just like that every speaker was working, except the stock subwoofer, in which I plan on getting an aftermarket amp and subs anyway. So If you ever need one this is the way to fix your system.

This harness worked great once I found the amplifier under the drivers seat! Instructions were clear and concise. Wiring was extra long, so there is plenty of left overs! :)

Great product, after unwinding the miles of wires, necessary to reach all parts of the car. Prevents all the 'wiring' issues when you replace the stock head unit with a new one and are installing a new, aftermarket amp.

This worked great. Yes, it's a bit long, but you have to remember the civic sedan has the amp under the drivers seat. But it still has excess, I guess for possibly other cars. Overall, it's a great harness, and plug and play with the factory premium audio wiring to bypass the amp.

Easy to install, the extra long wires are a must depending on where your factory car audio amp is located. Warning! do not cut these wires until you have established the location of your amp, measure the distance, then add an extra 8-12" inch then cut.

great product

Does what its supposed to do. MUCH longer than what I needed, but cutting off excess wire is no biggie. Just makes it more tedious to run because fishing 12' of wire through little spaces is kind of a pain. The wires were zip-tied together every so often, so that helped.

Was what I needed

This harness was just what I needed to put a kenwood in my 2006 civic. I installed component speakers in the car so I would still have tweeters which I put in the factory location. I needed this to bypass the factory amp and it worked great. Just don't understand why it's 20 feet long!! I only needed a foot or two!

A pointless piece of the puzzle

I rated this a 4 because for the quality it's great, now if only I truly needed it..... I made my own essentially. So this is a waste of money for me. However now I've got labeled factory wires to wire anything else I may want to.

Works well in 2007 Honda Civic Si

There were no problems with the functionality of the harness. You will get wires that are about 14 to 16 feet long, so you will have to cut them as there will be no room behind your dash to stuff all that wire. This is no problem at all because I would much rather have too much wire than not enough. You will lose the use of your subwoofer and steering wheel controls, so an aftermarket amplifier and steering wheel control adapter will need to be purchased.

Not for 2008 CRV EX-L

This harness is not needed on a 2008 Honda CRV EX-L with factory subwoofer; there is no amp to plug it in. Crutchfield techs were great though and sent me out the correct one, which installed easily.

WRONG PART!!

I'm sure this is a fine product for the right car, but Crutchfield sent this to me for use with my Honda CR-V and I had to go out and pick up the correct part. The wires are CRAZY long on this unit, too... Not sure why you would need that much, but I guess it's always nice to have options?

Ok for basic radio

This harness is ok only for basic aftermarket install as it will still require you to splice/tap into VSS/VSP wire even though it is present in the OEM connector. The 09 Si civic has two illumination wires and most radios only have one (this connector only has one) so it doesn't help. It is also important to note that you WILL lose your sub woofer with this harness if you do not get an amplifier as all aftermarket radios only have 4 channels. The Civic Si needs at least five (you can run the front mid's and tweeters in parallel off the same line (thanks Crutchfield for that advice, works great)). This will work great as I will soon buy an amp to get back my subwoofer. I think this harness should have had the VSP wire (that is common in GPS aftermarket units) as it IS in the OEM harness. As it is for the honda civic they should know and tell you that there is an issue with the illumination as well. You get tons of wire so there many options to run the harness. Center console to under the seat only takes about a third of what they give you. Good quality wire too! Hope this helps everyone looking at this.
