Ya no problem man, I'm glad to help

Ya they are both good amps by great manufacturers.

Orion has been around a long time almost as long as Fosgate. Back in the day both brands were considered to be "cheater amps". They would keep outputing more and more power the more speakers you loaded on them and the more power you gave them.

Both of these companies have always under rated their power ratings on amps. Which is always a nice suprise

I heard a few years back that Orion went out of business but apparently they have recovered some what.
I don't know for sure if the quality of their product has suffered or not. Probably still a safe bet for quality product.

If I had to choose I would go with Fosgate. I haven't seen a defective one yet in over 10 years.

Also if you can afford it I would get the insurance on the Shipping or get the amp from the website I linked to last post.
Some sellers on ebay don't know how to protect items when they ship. Ask lots of questions on packaging the product for shipping and read the sellers reviews.

Hope it all works out well for ya,
Dutch

Thanks for the advice Dutch,

I think I'm gonna go with the rockford amp!


As for the wiring kit, do I need to get anything else for wiring it to the stock head unit or does it come with everything I need?

And I'm guessing I should spend the little bit of extra money and get the more expensive 4guage kit?

Is there anything else I need to buy?
Or, basically after I buy the amp and the wiring kit, all I will need to do is make the box, get it all wired up in the car and then I'm good?

The amp wiring kit should be all you need as long as it comes with RCA'* & a Remote turn on wire for the Amp, some kits don't. In which case you would have to but them seperately.

Here is a prefered name brand but you can go with any brand, as long as it has what I mentioned above.

You may also need a line level adapter to give you RCA output into the amp. This is for your musical signal into the amp RCA input.

You can get one from Future Shop or Bestbuy for $14.99 + taxes
Stinger SLOC

Your Fosgate amp may already have a high level input which you would just extend and connect to the factory speaker wires at the rear speakers for Left & Right musical signal input. Basically just takes the place of using RCA'* & a line level adapter like above.

I notice when I'm listening to music and I turn it up, it loses alot of bass, and if its a bit louder then that it will turn itself down, and then when I turn it back down, the bass and overall sound goes back up a bit by itself.

Does that mean that I'm not going to get as much bass out of the subs if I hook it up to the stock head unit?

(Right now everything is stock)

I'm not clear on what your saying about the volume going up and down and losing bass.
It could just be the settings on the deck or the difference in tracks (I'm just guessing).

The subs won't be powered off of the stock HU neither will the amp.
The HU wether it is stock or aftermarket is just the source for the musical signal, which goes from there to the speakers.

What I was saying in my last post is that you need a way to get the musical signal to the amp that your powering your subs from. Without the musical signal going into the amp there will be no sound from the amp or the subs.

With an aftermarket HU you would connect the RCA'* from the Rear or Sub output (on the back of the HU) and run the RCA'* to the amplifiers Input.

Since stock HU'* don't have an RCA ouput, you have to tap into the speaker wires at the rear speakers to get the music into the amplifer.

Most Fosgate amps have what is called a High level input. This is a special plug that takes the place of using RCA'*.

This plug will have 4 wires:

Left Channel
White (Positive)
White with a Black stripe (Negative)

Right Channel
Grey (Positive)
Grey with a Black stripe (Negative)

So you will have to get some speaker wire (probably 5 feet or so) and extend the wires on this plug so that they will reach your rear speaker wires.
Make your connections like I said above + to + and - to - on both the Left and Right rear speakers. I'm not sure of the factory wire colours (positive and negative) but someone else here can help you with that or I can look them up.

Then connect this plug to your amp. Now you have your musical signal input into your amp.

Have you bought the amp yet ?

When you get the amp check out the manual it will clairify things.

Who is helping you to install your amp & subs ?

I meant when I turn up the volume alot, the stereo turns itself down and I lose alot of bass, but then when I do turn the stereo back down, in a couple of seconds it turns itself back up a little and I get more bass back.

My dad and I are going to try and do this whole installation ourselves, and we are going to build the box ourselves too.

I'm going to buy the amp, wiring kit and that SLOC thing all off of ebay tonight and I hope to install it as soon as we get everything, that way I can enjoy it for the rest of the summer.

If you are getting the Fosgate Amp hold off on getting the SLOC Line Level Adapter.
You probably won't need it. Like I mentioned in my last post you will probably have the High Level Input on the amp.

The volume issue could be some kind of circuit protection in the factory HU.

What year and model of Bonne you have ?

I know exactly what you are talking about with the stereo losing power at high volume.

I do not know WHY it does it, but it is something that I have noticed in every GM vehicle that I have been with a stock stereo system. ( I don't ride in many vehicles other then GM, so I don't know if other makes do the same )

The sound is full and clean at low volume, with alot of bass. Then when you turn it up, the bass pretty much goes away in favor of the mid - high frequencies.

I would venture to guess that it has something to do with the power output capability of the stock head unit, that it doesn't have enough power to put out the bass at the high volume, so it cuts back. also, it is may be built in the stock stereos to help protect the stock speakers.

It shouldnt matter....


The HU shouldn't control the bass like that after the AMP.

Mick your have BOSE correct..

If so did you grab signal pre bose amp or after ?

if not check that you have the correct wires and if you do Tune you amp..

put your radio where you think you will have it most of the time (half) and start turning your amp up from there till your like the sound and so it does not over power your components.
