is it possible to take the speaker leads going to the stock hu, spilcing one end of an RCA cable into it and plugging the RCA into the low level input of an amp that doesnt have speaker level input? Is a line output converter neccassary?

 

Yes, LOC is necessary. For the best LOC's go to http://davidnavone.com/

 

i did it without a line output converter, worked fine for me.

 

also, forgot to mention, it has a built in crossover. I tested the amp by doing my "fabricated RCA cable manuever" with the X over set to "full". Worked fine.

 

What has a built in crossover? You must have a very low power amp in your headunit. Biggest problem will be that head unit amps are notoriously poor quality. At least the ones built that long ago. You also have to consider that your are pushing a resistance in the amp input that is likey not close to the nominal 4 ohms of most car speakers. LOC's are built for the specific purpose of what you are attempting.

 

im using a stock HU from a pathfinder. These HU have no preamp because the pathfinder has amps located remotely relative to the HU. My amp has 2 channels and 400 watts with a crossover. This will be the new remote amp for this HU. The HU has a nice stock look that blends in well with the rest of the center console and has a built in CD player.

 

another quick question, where is the hole in the fire wall to run the battery power line??

 

u have a pic of the headunit? and if ur installing in '95 there should be a hole in the center of the firewall, if not, u have to drill 1

I only payed 40 bucks for it BTW. It has am/fm and CD.

Can you be more descriptive about the location of the hole. (near the fuel filter, iacv??)

 

it is right behind the iacv

 

It is easier with most cars to drill a new hole for the power wire. Go to the hardware store to get a big grommet large enough to go around your power wire. Then drill the hole the size for the grommet. Many will post a way to route the wire through the fender. But that puts too many extra curves in the power wire. Every curve in the wire is like adding a resister - dropping voltage between the battery and amp.

 

i have a adapter that connects to the bose HU and gives you the outputs for your amp. PM if intrested, better than splicing

 

Curves???? I'm not sure if you are being serious or just fun'in with us!!! Yes tight bends in your power wire may cause a stress failure of the cable and /or insulation over time leading to a blown main fuse or worse, but I would think the gauge and length would be far more critical in terms of voltage drop. I've run the fender route (works really well in a 4th Gen) and the tightest bend is around the strut tower. Or maybe it's at the grommet. Then again it could be the transition from firewall to floor board.
Besides... since when do electrons care about bends? Check out the circuit board traces on your amp and you'll see what I mean.
Cheers!
