We have a lifetime warranty on the workmanship. Just keep your receipt, and if you have any issues just let us know and will troubleshoot the issue for free under the lifetime warranty (no diagnostic fees here!!). 

      The speakers will have their own warranty or we do offer a Product Service Plan to fully cover the speakers for up to 4 years.

The OEM speakers are yours to keep. If nothing needs to be altered in the vehicle to fit the new speakers, then we will also reinstall the OEM's back in the vehicle down the road (no charge if nothing is modified), just keep that receipt and work order (good value for a leased vehicle).

 2010 Toyota Corolla's speakers should be fairly close in size to infinity reference speakers (basket and magnet will be bigger). You should be looking at around an hour to do the front door speakers and the same for the rear deck speakers. If you do them at the same time, some stores may drop the price of the install a bit. So anywhere from $100 to $130 for the install of all four speakers.
