XLCA2 2-Channel Line Out Converter with xBOOST Technology and Remote Level Control

Its a pretty good loc. But the 4pin connector for the speaker inputs on mine dont tighten to good and feel pretty cheap imo. But it does the job and I was able to get it to hold good enough

This made it very easy to use my factory head unit with subs and amp

Try super glueing the connectors to the unit. The remote only works on the sub outputs which, I'm not using.

It works good but could be better....

Worked great to hook subs up im my kia. You get what you pay for.
