Stock hd-unit with aftermarket amp?

Its very strange, but not without merit to request an improvement on the high end. That being the case, I would recommend replacing the speakers with a high end set of components in the front. Just swapping amplifiers will have little effect on the natural charecteristics of the stock speakers.

The combination of a strong amplifier with your new speakers can make a difference where distortion and "lack of punch" are evident.

As a point of reference, I thought the A4 had a stock amplifier. I would investigate the output of the stock amp and try a simple speaker swap first.

I currently have 2 amps (5 channel soundstream, 4 channel alpine v12), a 12 in. fosgate subwoofer, a pair of kenwwod component. If I were to add my subwoofer, my 5 channel soundstream and change all the stock speakers but keeping my stock A4 headunit, you think that will improve the sound greatly?

yes i do. I think you will notice a huge difference. The trickiest part of the set-up is getting a signal from the head unit. First things first, we need to determine if there is a factory amplifier. You may want to search for an Audi forum and snoop around there.

If it were me, i would grab the kenwoods and toss them in as is. Swap out the fronts. See if it makes a significant improvement. Running wires and adding amplifiers is a big project.

I'm not sure how good those Kenwood components are. I personally would go all out on the front speaker seperates set, something better than the kenwoods. Maybe use the kenwoods in the rear?

I guess Im gonna have the Kenwoods, the Fosgate subwooder, and my 5 channel amp this weekend. Im gonna bring it to a shop, man its prob gonna cost me at least $150...

for the installation. I know the stock A4 headunit is preamped. Hope this upgrade with my stock headunit will sound good...so i can get my rock on rock.....

yeah!!!!

lol. check this. Will, in teh classifieds, has a set of phoenix golds, brand new for $60 per pair. You may not know him beyond this thread, but he's pretty hard core compared to us- and you WILL hear the difference. Your A4 takes has these stats
1996-2003 A4 Front 5" Rear 5 1/4" , 7"

If you have 5.25 in the rear, see him about those. I hear mixed things about 5 channel amps. try to get a 2 or 4 channel amp (4 is better since you can have more options down the road). For the subs, get a decicated amp. More money, but much better since you can match your wattage better. Seriously, check the classifieds. Its proabbly going to cost you about $150 for the parts alone...hell proabbly the amp alone. If it doesn't, something's up. Go to a store like best buy or cirucit city or Fry's. Look at their prices. That's about as good as you get on retail. It only goes up from there. Trust me. I couldn't afford a new amp. I salvaged my amps from my old car, like the Fosgate 4040DSM. THe only reason why i got a Basslink was because it came with everything built in, great reviews...and it was hella cheap off a trade

.

Also, you should be able to wire this yourself. If you can put a computer in your car, you can easily put a basic system in as well. THe hardest part is figuring out how to get the power from the engine (gotta find a hole or make one). Other than that, its uusally unscrewing a few things and taking apart yourdash, depending on how hard your car is. My celica was easy. This inifniti is a piece of work. Get yoruself an FSM, makes life easier and saves bills on mechanics fees for simple stuff.
