Car Stereos: rca jack help, rca jacks, rca jack

Question
Hi Justin,
I have been running a system consisting of a pioneer 800W amp powering to 10" P1's. I have a basic insignia deck with only rca jacks for the front and rear componets. There was no jacks for the subs so I plugged them into the rear speaker jack. This was no problem at first until I purchased aftermarket componets and a kicker 350W 4 channel amp. My question is, are there any adapters or something to allow me to fit all of these rca jacks?

Answer
Hi Josh,

You have two options here.  The first is to simply put a pair of splitters on the rears, and run both the amplifier and rear components off of them.

The alternative is to buy high to low-level output converters, and hook those up to the amplified speaker out wires on the deck.
