stock head unit, amp ?'s

is there a way for me to hook up an amp an a sub to the stock head unit. because i DO NOT want to get an aftermaket head unit cause the stock one just looks to good to take out.

thanx

yup, just get a line out convertor and you can use that to get the singal to the amp

To add an amp to the factory stuff you can do it a couple of ways.

The first is to by an OEM-1 made by PAC. Its plug and play with no splicing of the wires at all. It gives you a set of RCA (2 if you want) and a remote turn on.

The second way is basically an OEM-1 but involves you putting a few wires together yourself. Still dont have to cut any factory wires though. You will need a line level adaptor. I recommend an PAC SNI35. Then you'll need 2 radio wiring harnesses. A Metra 70-1858 and a Metra 71-1858. Take the 2 wiring harnesses and wire them together, color for color. You'll end up with a harness that plugs into the cars radio harness on one end and plugs into the factory radio on the other end. The blue wire in the harness will be your true remote turn on. Then take your line level adaptor and wire it into the speaker wires on the harness you just made. If you tap off the front speaker output the colors will once again match up. Now you have a harness that allows your radio to work exactly the same as before but with a set of rca outputs and a remote turn on.

Both ways are essentially the same thing, just that PAC has made it slighty easier.

The second way can be found using parts that you can buy at just about any car stereo store but requires maybe 10 extra minutes of work on the bench wiring it. Either way the price will range between 50-60 dollars.

Another option is just to splice the line level adaptor directly in to the cars radio harness. Perfectly fine but I dont like having to touch the factory wiring if I dont have to but its cheaper as you are only paying for the price of the adaptor and not all of the extra harnesses. You would hook the input leads of the line level convertor to the front or rear speaker out puts of the radio.

that's another way to do things:thumb:

thanks for helpin out
one more ? witch speakers would be the best to run it off of i have the mosoon system so there is a set of mids in the back seat that are stock would that be the best place to run it off

thanx again

also is this what you are talking about

in my experience you will get better sound out of an aftermarket head unit because the rca preout voltage will be higer. im not to sure but i think a line out converter will only put out around 2.5V as opposed to a alpine (or any other decent head unit) that will have 4.5 or 5 V preouts. just my 2 cents;)

spoonjimlt1: the link you posted is the wrong one. Go for Focal speakers if you afford them. PM me if you need a place to get 'em.

slayer6x6: I agree but most CDPlayers have 2V, only the niceer units have higher. A line driver can definately fix that in a hurry though.

Where do you guys pick up LOC's online? I'm gonna need one for an install I'm doing here pretty quick on a Mitsubishi 2G Eclipse.

do you know exactly what the voltage preout is on a line out converter? i was told it was 3.5 but that seems a little high.

It all depends on the particular LOC that you are using. Some are even adjustable. On some of them they are entirely passive and the output depends on the input. There are many variable that go into them and quite a few different circuits that can accomplish the same thing, with varing degrees of clarity ofcourse. A good LOC and a good line driver can be just as good as an after market HU. But the Monsoon isn't the cleanest HU, but it is do-able and can have a great outcome. But a good aftermarket unit will always be more prestine as it's made to do just that.
