I just bought a 98 Cabrio and it has this option.

I see that it has one tweeter and one mid on each door.
It probably has the amp in the trunk as well.

Do you know if I can upgrade to the Harman kardon amp and add the small subwoofer in the ski hatch?

I know its not the best ICE you can have but I want to keep it OEM.

Thanks
George

if you take that amp out, you'll have to get new speakers otherwise it won't sound right at all

Are you speaking from experience or somebody told you?

As dar as I know, if the speakers are rated at 4Ohms, they should sound fine with aftermarket amps and active crossovers.

^^^^

Roozworks for tweeter. (AKA Hi Fi Buys) and beleive me he knows his shit. He's pretty much considered the go-to guy on car audio around here. Anything he says, you can trust. he won't lead you astray.

Yes, but their power handling is quite limited; consider that the stock amp only outputs 15w/ch at maximum. You can probably get away with it if you replace the amp with a comparably rated aftermarket one, filter out the low end, and let the sub take up the slack. But in the end you'd only bring out the worst in the stock speakers. That's what Rooz meant, and most people will concur- the stock system really works best when left alone . . the HK amp has the crossovers built in, so you'd have to account for that, too. I would leave the current setup as is, and just add the sub and add an amp to power it.

Guys,

Its not the HK configuration. It has the smaller amp which indeed sounds like CRAP! For starters I am going to remove that amp and install 2 4 channel amps with an active crossover driving the original speakers.

Then, I will change them one by one to get the most out of the system.

Thats my plan

why 2 4 channel amps?

But keep one thing in min, if you want "better" sound the speakers are the key to this since it's what creates the sound in your car
