Can someone please help me on this; I'm a little confused.
I want to upgrade the sound system in my 2001 bmw 330ci (non H&K) and here are the components I already own:
(1) 2-channel amp w/ built-in crossover, one 12" sub and a capacitor (all Rockford Fosgate).
What I want to accomplish is:
- Use my already own 2-channel amp with the 12" sub for a deeper bass
- Upgrade the front and rear speakers and tweeters (for a cleaner sound)
- Get a new aftermarket 4-channel amp w/ build-in crossover to drive the front and rear speakers.
- Retain my OEM head unit.
I understand that I will need a Peripheral Vendetta 4 to convert the outputs from the OEM head unit to standard RCA.
So if I got this right I'll use channel 1 and 2 from the 4-channel amp for the front speakers and channel 3 and 4 for the rear speakers (high pass only). The configuration would be as follow: OEM Head unit speaker outputs -> ven4 -> aftermarket 4-channel amp -> front and rear speakers
My question is how do I setup the 2-channel amp to the sub? Which wire would I use from the OEM head unit to the 2-channel amp to drive the sub and would I need another ven4 to convert the cable to RCA?
