"I bought these speaker adaptors for my Corsa as the speakers I had purchased would not fit correctly. The adaptors allowed me to attach them to my new speakers and then fix them to my car for a perfect fit.
Would definitely reccomend to anyone fitting new speakers into their Corsa, as you probably will need these."
Pros: simple to fit they just work, reduces vibration
Cons: cables provided are pointless
"Very simple to fit. I actually fitted my speakers without these first time round and then stumbled upon this product. When fitted without these you get a lot of vibration, when fitted with the adapters you get near none which helps with base and quality. The difference in sound quality and base response was as clear as night to day. Don't bother with the cables you get with it though, they don't really do your new speakers any justice and are fairly unreliable."
Cons: wiring adaptors not worth bothering with at all
"The plastic speaker adaptors work perfectly well, very happy with them. This kit also comes with some wiring adaptors, don't even bother with them. When I used them the speakers cut out intermittently, simply cut off the stock connector and use crimps instead, a much more reliable connection."
Pros: the adapter is the right size and easy to fit.
Cons: the cable adapters are cheap and unreliable.
"What's to tell? If you need an adapter kit to fit after-market speakers to your old Corsa, this will work. The quality mark is low because the cable adapters don't give a very reliable connection - I ended up clipping wires and using terminal blocks to connect instead. A common problem with these adapters I believe - I had the same trouble last time when I did the wife's car."
