long story short, I totaled my S2K (with a KDCX993) and I’ve never had a head-unit with lower than 4volts pre-out. Now I have a 4runner with the AVIC-U310BT installed. It’s a bare bones solution to gps/ipod/navigation and I really don’t have the cash for a high-end (+4volt) replacement unit.

So I’m looking into a Line Driver as a cheaper solution. It seems the Rocksford Fosgate RF-BLD may be the answer. Here’s what I’d like to know.

-Will I loose sound quality compared to a head-unit that has high volt pre-outs?
-Is there a better line driver out there for my situation?
-The U310BT only has 2 sets of RCA pre-outs Im using a Y-splitter into my 4chnl mids & highs amp. Do I buy one 2chnl Fosgate RF-BLD and split after the driver into the amp?

Any over-all advice would be appreciated!
