I got my Pioneers about a year ago to link up with my car audio system that already features a top of the range CD player and Amp. At first I was thinking... Will the Pioneers really make that much of a difference, As £120 was a pretty heavy price to pay when your going in blind and don't know if they will make a difference. But I must say I was pleasantly surprised! To set them up I had to remove the parcel shelf from the back of my GTi and cut 2 holes with a jigsaw where I wanted to put them. At this point you need to be exact and cut both holes exactly where you want your speakers to sit on the parcel shelf as there is no second chance with this, If you mess it up it means buying a new parcel shelf. Thankfully I got it first time! Once the holes are cut out then you place the speakers in and they should fit exact as long as your measurements are correct. Next thing I done was get hold of the in car speaker wire that I had to connect my pioneer speaker wire up with to complete the job. Once I got the wire i then had to connect the male ends with the female ends on the car wire to fully connect the unit. I recommend using cable ties when they are connected to keep all the cables tidy when you tuck when away back up inside the car out of eye view. Once I completed this part then I turned my audio system on and the speakers worked first time. I think that the pioneers made quite a difference. The sound they produce is top quality, No fuzziness at all like you get sometimes off of cheap speakers. I would say completing the proccess of connecting the speakers up with the car was pretty easy for me, But I have did this before and had my boyfreind there to talk me through it. So I hope this review has talked you through it and will help you get connected and also help you figure out whether the Pioneers TS Q172C are for you. Good Luck
Although I am sure a lot of Vauxhall owners are not aware of this, Pioneer designed their TS-Q172C Component speakers especially for their car. They are said to be custom designed to directly replace the factory fitted speakers in the Vauxhall range of cars. Due to this, I found the speakers very simple to fit as I could use the same fixing points to secure the 17cm kevlar cone woofer in place. The supplied fitting guide is also very useful and concise regardless of which Vauxhall model you own. The 2.5cm dome tweeters are key to improving sound quality and I have found that the sound is much more lively and has more dimension to it compared to the flat, dull tones of the factory speakers. Offering up 89db of sound they are a 10-fold improvement on the factory speakers which have cones made from paper!
I were impressed by the design and quality of the product and although paying around £100 may be off-putting to most, I would say they are worthwhile if you intend on keeping your Vauxhall for many years. For me, however, I do believe that this whole 'designed especially for your vauxhall' is purely a way of shifting more units. I cannot see any reason why any other set of 17cm components wouldn't fit as easily, so this claim doesn't hold much value for me. On the other hand, it is hard to get away from the fact that these components are worth their money - the sound quality is excellent, and they will improve the in-car sound no end. If you are looking at spending less than this to improve your audio system I would suggest you don't be scared to look elsewhere.
