Monoprice RCAs
can be nice. But you have to get lucky and get a good batch. They're not too flexible and sometimes you get connectors that are either too tight, or not tight enough.
SounDrive offers two different lines of cables that are both very flexible, grip the connector well, and doesn't use a cheap shield that you can see right through //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
When you cheap out on the actual cable used to build RCA interconnects, you typically sacrifice the shield - the most important part! I believe you'd be very hard pressed to find cables with the craftsmanship and quality materials we use for prices anywhere near ours. We've disassembled lots and lots of car audio RCAs and it's usually not pretty.
To top it all off, every cable is hand built in the USA and tested individually.
