Running an amp and 4 speakers off the factory head unit?

[sinner6.0L]

Ahh heads up I have an 06 F-250 and I posted this in the wrong forum! sorry

Well I've had enough of the stock speakers so I'm getting 4 alpine SPS-517 (75w) speakers and a MRX-F35 (55-60w) amp for the truck.

I realize the head unit is going to be the weak link in the system but I'm not really interested in upgrading it at the current moment. The amp has speaker level inputs so I should be fine hooking it up. How much is it gonna hurt my sound though?

Anyone have any input? My head unit is a factory 6-disc and I kind of like the factory look.

The only way your headunit will be the weak link is its lack of adjustability. That and it may have a fairly low point that it start to clip at, I haven't had a chance to test for clipping yet though.

Well I guess the worst that could happen is it doesn't work correctly and I have to get a head unit. That's really not a problem if it comes down to it though

You need a line converter to work it all together. I did this to keep factory look, but badass aftermarket sound

are you guys using the LC2i line convertor like the ones I see on ebay?

edit- okay I see I can use the LC6i to put 4 speaker channels in and get 4 RCA level channels out to feed the amp. I'm probably not going to start out with that, we'll see how well the amp handles the 4 speaker level inputs by itself first. If I feel there is a sound quality issue or maybe further down the road I'll add a LC6i

I don't plan on ever running any subs. I'm passed that stage plus I definitely don't have the room

You shouldn't need a line out converter since your amp has speaker level inputs.

However, what you could do is get a line out converter to feed an EQ, then use rca's from the EQ to your amp.

Set your treble/bass settings on your head unit to flat (middle) setting and use that PEQ to tune your system.

I run the lc2i to feed a tiny amp and sub, just cause I enjoy a "fuller" sound. Its small enough that I just stashed it under the stock HU inside the dash.

I use the lci2 to run a 12" shallow mount behind the rear seat.. Works great!
