rca 4 channel cables

I'm needing to purchase 4 channel cables to go from my head unit (Kenwood KDC-X993) to my 4 channel amp (MMats SMT4090). What should I look for in my cable purchase for the best possible sound? The cables will be hidden, so appearance is not a concern.

Twisted pair technology is the basis for my selection. I also like the connector barrels(ends) smaller for tight space applications. If the metal is real thin and dull looking on the outer conductors at the ends, the connector probably dosnt hold snug. Id stay away from those.This is what I do for FUN!

As stated above, shielded wires are the way to go. Also run these RCAs along the opossite side the power wires are ran. Ensure clean engine noise free install.

Any RCA cable designed for a low level signal transfer will be a shielded cable.  I have heard of only one incident where running a patch cord next to a power wire caused engine noise. Let's Go Brandon Brown. Congratulations on your first Xfinity Series Win. LGBFJB

At your audio ranking level its uncommon I suppose, but i've had to deal with plenty "budget" installs that have "4ga" wire that looks like factory speaker cable. So $10 power wire and $5 RCAs = " I have engine noise no one can figue out". I've seen more often since the decline of the economy..... Sad really.

The other day at a swap meet I checked out some audio stand and the 8ga cable the guy had could literally be stripped in the 12ga notch of wire strippers. But then he proved me wrong because LOOK its printed right on the sheathing. Oh ok. Lanzar/Pyramid wire.This is what I do for FUN!

As stated above if you run it on opposite sides of the car it should not matter a ton. But just for that extra comfort I usually go with rockford fosgate Dual twist RCA cables. They haven't failed me yet. Power cable wise, just pick a name brand cable. So you actually get what gauge of wire you are paying for. Instead of scosche's 4ga wire is actually a 8 or 10 ga wire. Same thing with pyle/lanzar.
