what do i wire an aftermarket amp to, so that it will turn on when i start the engine?

Fuse #7 in rear fuse compartment - typically it is used for radar detectors but why not amp?!

P

will it be powerful enough to turn on a 350watt amp?

thanks for the help

I'd use the #7 output for the trigger only. And have a dedicated fused line from the battery to the amp.

Yes since it only used for the trigger. You would want to wire the amp directly to a battery feed protected by a fuse. I wouldn't run it all the way up fron to the battery. I would try to find a way to tap into the powerfeed for the back fuse box. The wire feeding it should be big enough to handle your amp in addition to the rest. These big feeder wires are usually overdesigned. Hope this helps.

This is an old thread
I am a noob at these stuff
Well, I am thinking of putting my sub and amp into the C230 coupe. I found out that the remote turn on wire goes to fuse #7. I have tried searching and most of the installs are not on the non bose or non audio 10 stereo.My car doesn't have the audio 10 nor the BOSE system. Can somebody tell me what are the ways I can do it? I don't think my stereo has RCA outs. Main question is, where do I plug the RCAs from the amp to?

Thanks

You need to get a line level input. Either your amp has it built in and you just need to plug it in, or you need an adapter that converts line level into pre-amp RCA outputs. The line level input gets taped into the speakers in the rear deck.

Hello to all, I am new to the forum.
I just did a subwoofer system installation on my 240.
You can get a line level to RCA signal converter and plug that into your mono amp. Such as this one: http://www.electronixwarehouse.com/car/sgl-prod/accessories/line-converters/legacy-ln60.htm
power line is drawn directly from battery with a separate fuse (I hung that right beside the battery), the power line will run through the dash, along side the passenger side (with the rest of the wires), through the backseat into the trunk. I was told that I should run a separate power line since my amp is too powerful, if hook to the brake light assembly system to draw power, performance (of the amp) will suffer.
Hope that helps.

Thanks for the help dna_errors and Capt Nemo o2.
Is a line level converter the same as those hi/lo converter?

If your in the coupe... you can tap in from the rear sub cables in the back right part of the hatch.

For the power i ran a cable to the front of the car. and I also used fuse 7 to turn on the amp.

I did mine ghetto style with electric tape to protect the tap.

And i just wrapped the "on wire" around a fuse and pushed it into the fuse box. (Some one made a fancy spade adapter thingy to plug it in.. but my way has worked fine for a few yrs now)


I didnt even use a converter and it works fine.

Would you happen to have any pics of where that is?
I do not know if my car has that

Thanks

I can post some pictures later.

But in words...

If u open the hatch.. look to the right "wall" there is a pannel that u can remove. The sub is there. If u look deep in the space.. there will some wires that you can tap your amp into.

So I plug the two RCA wires in there?

Thanks.

there are no plugs for this. This is tapping into the line straight.

If your amp does not support this, you need to get the converter.

Is there a way to tell if my amp supports that just by looking at it?
I can not find the specs online and I dont have the manual for it

usually there will be a plug that says line level, or an extra set of screw connectors. What is the make/model of the amp and how old?

It's a Sony Mobile ES XM260G, I don't know how old.

I got around to hooking up my amp today. For the inputs i tapped into the rear sub wire. Is there any advantage to tapping from a rear door speaker as opposed to the stock sub? I notice that sometimes the sub doesn't exactly increase volume the same as all of the other speakers. I did disconnect the Bose mic also.

You do realize this is a 3 year old thread you resurrected, right?

As far as your question, I would think that connecting the amp to one of the rear speaker lines is a better idea if that's the type of signal the AMP is expecting. Connecting to the sub lines gets you a signal that is probably only carrying the bass for the sub itself. I'm not really too sure but that's my 2 cents.

It's actually over 5 years old, but it's better than starting up a new thread for a simple question. I guess i'll try it both ways and see if it makes a difference.
