Dickheads!

Well, through my research I found out a couple things:

1) The Rockford Fosgate Premium Stereo for the Sentra futures a headunit with 6V preouts, just need to convert them from 18ga wire to RCA cables. No LOC needed.

2) You can piece together a bare bones RUX-C701 for less than 1/2 price.

I am particularly interested in #2

They caught three teenagers that were breaking into a bunch of cars in the neighbourhood next to mine last night. So, I'm going to be calling the cops & inquiring after work. The ident guy said he'd be able to match any suspects with what he recovered.

Those part numbers I sent you Sean will get you the controller & the DIN cable that connects to the H701.

Just made the list of damaged areas for the insurance company. Have my insurance assessment in about an hour.

[ANeonRider 3]

Estimated damage total came to $3400. The adjuster said she'll get back to me on my stereo value by the end of the week. Likely will be $500 or so.

Picked this HU up. RF stock unit w/ 6 disc changer. Have to wire the 6V preout to RCA cables to run to the H701. Also still need to order the pieces for the C701 controller.

Insurance is giving me $655 to replace the D310, which isn't bad at all.

[Aaron Clinton 2,372]

That's good!

What would it feel like inside the trunk of a playing IB install w/ it sealed up?

[ANeonRider 3]

The same as in the cabin.

[nick_19 1]

Huh... odd.

Makes sense though.

So, finally got around to getting a source back into the Spec V this morning.

Bought a Rockford Fosgate factory premium head unit to be my signal source. Comes with 4 6V balanced outputs, AUX input (for my Ipod), CD changer (not used), and less likeliness of being removed from my car & causing $6000 in damage. The head unit came with a stock wiring harness, which I was able to use so that I didn't have to cut any factory wiring.

I also picked up a C701 controller with the insurance money to control my H701.

Since the RF factory stereo package comes with an external amplifier, the head unit has a 12V amplifier turn on output. Unfortunately the current that this output can source is very low, so I had to use a PAC TR-7 to allow myself the ability to turn on the H701 & my 3 amplifiers.

To connect the 6V balanced outputs from the head unit to the H701 (YES, the H701 accepts BALANCED inputs, read more below), I cut the ends off of a RCA cable and soldered, then heat shrinked the outputs from the headunit to the bare RCA wires. Since the output is balanced, it eliminates all common mode noise to the H701, eliminating the chance of noise at the RCA inputs which lots of users have experienced.

The H701 is then wired to my amplifiers & controlled by the C701. I use the RF head unit as my volume control & set the C701 volume to a set level (in this case, 25/35).

Since I just got done about 30 min ago, I haven't had much time to listen, but initial impressions are that there is no difference in sound between the source I had prior to the break in (D310) & the RF head unit. I can say I am very happy with the results, and relieved my idea actually worked out, especially since I haven't seen anyone else report using balanced inputs with the H701.

As for specifics about how the H701 can receive both balanced & unbalanced inputs on the RCA input...

I had read Werewolf on ECA had written that the input stage of the H701/700/900 has a differential to single end converter that measures the difference between the tip & ring of the RCA input. This then referenced to its own internal ground. Such a design would allow for the use of both unbalanced & balanced inputs. I then read that some individuals had successfully done what I want to do, with the H650.

So, I decided to be the guinea pig, and try it out, and indeed, what Werewolf wrote is true. Hope this information spreads to help others that want to use balanced inputs with the H701 (although it is now discontinued).

good job man!

glad everything is up and running again

[///M5 2,833]

Nice!!

[Estsound 7]

Just awesome work, hope to see more pictures. Btw i sent you a pm.

[Tre The Truth 2]

Makes me want to start a project on my Sentra.

Niceeeee setup man, bet it sounds clear.

[chainsaw 5]

wow. its been a while since you updated. where are you at on progress?

[lithium 358]

from the grave guys?

[///M5 2,833]

I've been in that car after the install and it sounded great.
