hey guys, just picked up the scion xb release 3.0 envy green today, its such an awesome car, but im kinda new to these forums, i looked and looked and couldnt find my answer

i have doen nothign to the audio system yet, but what is needed to hook up a amp and sub to the alpine HU this car comes with. im pretty sure it does not come with pre amop outputs, but is there a kit or wiring harness you can get that adds them? and where could i purchase one? ill be updating my profile with the release number and everything, becoming a premium member and uploading pictures. anyways, ill be adding a kicker 12" l5 solobarrick and a kicker 200 or 300 watt amp, i forget what model i have, i also have mtx crossover im not sure if i should add in with the system, kicker amps do have internal crossovers. also, the alpine speakers it comes with would it be worth it to get a second amp to hook up to its stock speakers? or is it possible? or could i do that temp untill i replace the speakers? ughhh so many questions, if anyoen could help me out with any of this it would be much appreciated. look forward to hearing some responses!

he installed my amp and stuff in my RS3

 

the Envy Green Stock Head Unit has RCA outputs on the back... nothing needed besides a set of RCA cables, and and amp...
you WILL want to get another amp for the door speakers though.. once you start to power a sub the other speakers will sound like quiet...

 

how many pre amp out puts? 1 or 2 or 3?right now i have my amp for the sub im putting in and a 4 channel kicker amp
