Hi,

I am trying to hook up a sub-amplifier to the premium sound system on solara.

I don't want to feed the rear speaker high level inputs to the amp. Does anyone know if:

1. the stock head unit has RCA out?

2. if no RCA, can I get the speaker level pre-amp signals and convert them to RCA?

Thanks,

mailskobe

1) The stock unit does not have any RCA prepouts

2) You can get a high-lo converter to convert speaker level signal into an RCA output. Just make sure you grab the leads going to the speakers after the factory amp, which is located behind the glovebox. The wires directly behind the factory radio send a low level signal to the amp. The easiest place to grab the high level input for the converter (available at any car audio shop) would be from the rear speakers.

HI,

thanks for the information.

i already am tapping the rear speaker wires directly into the high level inputs of my sub woofer amplifier since my amp has high level inputs.

do you think using a high-low convertor could give me different results?

i would ideally want to feed my sub-amp with pre-amp inputs, since the post-amp inputs are already conditioned.

do you think its possible to do that?

I don't think you'll notice much of a difference between using High or Low level signals unless you're running a competition system.

If you really want your amp to receive a low level signal, you can use an LOC like this one and tap it off the rear speaker leads.

esmith69 has suggested David Navone products if you can afford them. I've gotten to trust his word, and if he says they're good products then I believe him

well, i can use the LOC but as you said i wont see any difference since the LOC input will still be speaker level output that will be post amp (stock amp)

i want to feed my sub-amp with pre-amp output from the head unit.

possible?

There's no way that I know of to do that without having existing RCA pre-outs.

Even if the factory stereo does not have factory amps, the speakers are still receiving an amplified signal from the headunit. The LOC's do an excellent job of converting the signal back to a low level, non-amplified signal with no real distortion/signal degredation. If you truely want Low Level RCA signals to your aftermarket amp using the Factory headunit, then using an LOC is what you want to do.

Either that or spend a couple hundred smackers and buy an aftermarket headunit that has RCA pre-outs for subs Solara Stock Premium sound system -- posted image.

ok cool, final question:

i have currently tapped the rear speakers right where the wires connect the speakers and put them in the amplifier high level inputs, i am not happy with the sound at all.

do you think there is something wrong in my installtion, or is it because i tapped them too late or any such reason?

shud i try tapping them earlier? will that make a difference. the amp installtion guy here said that i shud use high-low convertor and that will give me much better output.. WILL IT?

thanks again

I'm not sure if the location of the tap makes that much of a difference (just as long as it's done after the factory amp), but I try to keep it as close to the amp as possible.

When you say "i have currently tapped the rear speakers right where the wires connect the speakers", did you use a special splice connector with 2 male prongs? Or did you crimp the 2 wires together, then hook it up to the speakers?

The "high-low convertor" your installation guy recommended is a Line Out Converter (LOC) like I recommended, it's just another name for one. Most amps will perform better if they receive an unamplified low level signal, so I'd say give it a shot. Your amps internal high-level input converter may be faulty as well, which could add to the distorted sound.

Recommendations...

Install an LOC like this LOC or one of these and tap it as close to the factory amp as possible (give it at least 1 to 2 inches after the amp before you splice)

yeah i know LOC is same as high low, sorry for using a different name.

I basically exposed some of the the stock speaker wire and then soldered the new speaker wire to it forming a T. do yo anticipate any problems with that?

i will try the LOC.

Thanks,

There shouldn't have been, as long as the connection was secure before you soldered. Most "T" connections that I've done, I would tightly wrap the wire around a couple of times to ensure a good connection point, then solder. Not sure if that's how you did yours but I thought I'd mention it. Let us know if the LOC did the trick
