I used this with multiple automotive amplifiers, an eight channel active system. Easy to assemble the cable (Mogami cable) through the RCA and solder them with silver solder. Some people could be amateurs when assembling the cable, forgetting to place the outer jacket behind the RCA jack before they solder both ends of the cable. With this it wouldn't matter because the jacket slides from the front because of the positive lock system it features. I wouldn't know how to rate it's performance regarding sound quality because I'm just an amateur listener, although I love SQ (sound quality) in mobile sound systems. I have noticed my sound system became more crispier than my last setup. I'm not sure whether it was due to my addition of a new processor (Audison Bit One) or my new RCA's. I'm falling more towards the RCA's because it didn't sound as good before the new RCA setup was used. The only drawback is that the jacks were much wider in my application, the female RCA it was connecting to is in a cavity instead of fully exposed socket. I had to grind the plastic surrounding the jacks to use push the RCA completely in the socket and use the locking system. I'd advice not to the locking system too much, you my have difficulty removing it when needed and have to ruin the female jack for it to come off, I just screwed in in by a click. Yes I'd buy them again for it's price and performance not to mention ease of assembling.

I bought these and made my own cables using LC1 cable and I know have connectors for my stereo system that would cost me hundreds of dollars each instead of doing 5 sets of cables fro under a $100. These plugs are really great they lock on nicely.
