Is there a way to retain use of the non-Bose stock head unit while using external amplifiers? I want to keep a 100% stock look with my audio system. I plan on putting a 10" woofer in the Bose location using a fiberglass box, replacing the front speakers and tweeter with a component set, and just leaving the OEM rear speakers since they are just filler anyways.

The amps will be placed in my glovebox.

i would also like to hook up my carpc (also completely hidden to retain stock look) to the stock head unit so i can play MP3s. If this is beyond the capabilities of the stock head unit, would it be possible to at least reuse the rear speakers with a new head unit? I know on my 300zx, the Bose system ran at 1 ohm and had external amps, so when you changed headunits you either had a buy a very expensive adapter or replace all the speakers.

Thanks!!

 

Yes...You need a line converter.

I bought this unit from David Navone

VARIABLE 4-CHANNEL HIGH-QUALITY OEM ADAPTOR

Some Specs:
The N-7785V is a four channel device that features two channels of full range output, plus two channels of low pass out with the same bass boost as the N-85 and N-85V. The signal level can be adjusted from a maximum of 9.5 volts rms down to zero volts. This is a great feature for optimizing the S/N of system and a must for competition or demo systems. Turning the ***** clockwise increases the signal level. At the amplifier/speaker we recommend a 1:3 gain structure for most systems. The N-7785V is a great device to connect an OEM deck into TWO aftermarket amplifiers. The front amps can be fed a full-range signal and the rear channels can be low-pass only.

This is the best unit I've owned! I have it hooked up to a JL 300/4 and to my surprise there is NO noise what so ever or amp turn on pop. I also bought two plugs from Metra...One that runs into the radio and one out of the radio. That makes it 100% plug and play! I cut no factory wires during installation!

Good Luck!

 

i will take a look at that product.

Is it possible to hook up my car pc? it would usually connect into an Aux in like an Ipod....

 

Wouldnt i need a 5 channel output? One for FR, FL, RR, RL and bass? It says two are for bass and two are for highs. Does this mean i would only be able to control Front to Rear and not left to right? this all confuses me.

 

a

 

jl audio clean sweep....i think we can use that too

 

This will have 3 pairs of pre-amps and an aux input? it seems like it only has 2 sets.

i need 1 set for front speakers, 1 set for rear speakers, and 1 set for the subwoofer.

 

How many amps are you running?

I've never seen a 3 pre-out converter b/c you don't have an output or a way to control the subwoofer from the head unit.

 

1 4 channel amp (obviously for the mids and highs) and 1 1 channel amp for the sub.

The first unit suggested has 2 pairs of pre-amps...1 for highs and 1 for lows....but then i would lose the ability to use fade and balance.

 

Well you could get a different unit and he also sells one without the filters and bass boost. I didn't run rear speakers just front components so I didn't care about the fadar but balance is still there.

From the radio you only have (RF,RR,LF,LR) so you only have 4 inputs.

Personally I would loose the fadar and adjust the rear speaker level via the gain on the amp or buy an EQ with a sub output.

Just my 2 cents!


The only reason I recommend the guy is I've never had good luck with LOC's and this is the best I've ever owned. This model is 4 full range channels

The NE-774V is a competition quality, four-channel OEM to aftermarket stereo adaptor that was designed to connect the speaker level outputs of a factory deck into the pre-amp level inputs of an aftermarket equalizer, electronic crossover, or power amplifier. The signal level of the NE-774V can be adjusted from a maximum of 9.5 Volts rms down to zero volts. The NE-774V replaces our previous N-774V and the main difference is in the Plug and Play wiring and connectors. The circuitry is identical to the 2-channel N-7V and N-777. Notice that the signal level adjustment pots are inside the plastic enclosure. Simply squeeze the lid for access to the adjustment pots. Turning the pots clockwise increases the signal level. We recommend leaving the internal pots at the maximum level unless there is a good reason to decrease the level. The NE-774V features full transformer isolation with a maximum useable signal level, and a smooth frequency response -- which means more signal and less noise. The NE-774V includes compensation for both frequency and phase with no loss of bass or treble. The maximum signal level output of the NE-774V is 9.5 Volts per channel. This is an incredible level and amounts to over 4 times the signal level of a typical aftermarket deck with only 2 Volts of signal. The NE-774V is the best LOC (Line Output Converter) in the world.

 

with the 774 unit, is there a way to incorporate an Aux In like the JL unit?
