Pioneer TS-R6951s 6" x 9" 3-way Coaxial Speakers (400W) : desertcart.co.uk: Electronics & Photo Review: Recommended addition to OEM system - How to fit to 2016 (mk 2) Hyundai i20 SE in rear doors: If you have found this review it's because you want to benefit from the addition of rear door speakers to the standard front speaker only setup in the SE pre-revision model. First you need to know that as well as the speakers you need to buy fitment rings. They are available from car audio specialists via the well known auction site, at less than 15 GBP for a pair. The speakers come with 8 screws that can be used to attach to the rings. You will need 3x short, fat screws to fit the rings to each door. I found the screws you use to fit hinges to kitchen cabinets were perfect. Removing door card is simple. There are two screws, one by the door release handle under a flap and the other under the rubber mat in the hole in the arm rest. Once screws are removed use a soft plastic lever to get behind the door card, starting in the bottom corner nearest the hinge, and gently pull the door card away from the door. Once you have been around the bottom half of the door and felt the panel unclip, you can lift the door card off. Once you unclip the electrical connector, you can put the door panel to one side. The SE model has speaker wiring as part of the wiring loom. If you look carefully at the loom, you'll see the speaker wiring connector is taped to the loom. Undo the tape and you'll have enough length on the wiring to pass it back though the door and position behind the hole for the speaker. Next screw the speaker to the ring. Fit the parts together and offer up to the door before screwing together so that the ring is the correct orientation. You can see from my picture it only fits one way. You may need to trim the inside edge of the ring with a Dremel to ensure an even and snug fit. Next make the electrical connection between wiring loom and speaker. You may need to remove the black plastic from the connector unless you can find the right plug in connector to fix to the speaker wiring. I didn't find a significant difference in sound based on correct or incorrect polarity. If you wanted to check the wire colours to ensure +/- is correct you'd need to find this from Hyundai. Test the speaker works at this stage. You'll need to play with the F/R fader setting to send signal to the rear speaker. Next screw the speaker fitment ring to the car door. Make sure it's nice and tight so there's no vibration. You can then replace the door card. Do the same on the other side! The balance between front and rear speakers is good and the power output of the head unit is sufficient to allow a high maximum volume without distortion. Frequency response is good, and bass is sufficient. This turns a good set up into a better one, without breaking the bank and without damaging or altering the standard look. Go for it! Review: Great Speakers - The sound quality is great overall and are as easy to install as just about any other speakers. Fit perfectly into my doors and improved the audio quality heaps compared to the 30 year old ones they replaced. Great value for money. If you dislike the grill design it's removable so you don't have to fit it. Great performance overall.
