How-To:Getting a pre amp signal from OEM midline 6-CD stereo

[drpeeb]

I have a factory-refurbished Kicker MX700.5 5-channel amp in my boat that I got off eBay for $310; It works perfectly so I am OK going with refurbished, for now anyway. So ...

I see that both Kicker's 5-channel ZX700.5 (70W x 4 + 210W x 1 (sub) RMS (4 ohms)) and 4-channel ZX850.4 (175W x 4 RMS (4 ohms)) accept both low-level (normal RCA's) and high-level (speaker level) inputs. Their latest models of these just have a button you push for whether you're inputting low- or high-level signals.

I think these would eliminate both the need for an LOC (Line Out Converter) or trying to perform the OEM HU modifications described in this thread.

A new 5-channel ZX700.5 on eBay is about $315 including shipping
A refurbished 4-channel ZX850.4 on eBay is about $290 including shipping

If you're going to buy an amp anyway, wouldn't this make sense?

What do you all think?

Would the guy above me idea work it would save me a lot of trouble?
