hey guys, i have a question, in order to install after market suboowfers and amplifier for 2007 scion tc, would i need to get an amp adaptor plug, or can i directly connect to the "upgraded" pioneer system with ipod cabapility. Thanks.

 

You just need a line level convertor... and that will give you the signal you need for your amp and subs....

It's not expensive and is the best option, other that going for a full deck replacement.

 

need a line level converter? I have one for $10 shipped. Use for a total of maybe 1 month.

 

Or, if you have an amp with high-level (speaker-level) inputs, you don't even need an LOC.
