Replacing the Bose subwoofer on my A3 8P

[galanot]

Hi there!

Last week I replaced the Bose subwoofer for a good one. I knew that bass was the weak point of this system. I've used a high quality custom made enclosure by RadioWorld (UK) and installed a Sundown SD-8 sub and a SAE-600D from the same manufacturer. The result is awesome.

The Bose subwoofer is pretty hilarious:




The custom made enclosure bought to Rw-online.co.uk
Impressive build quality:




Since there isn't an official distributor of SA gear in Spain, I had to buy it directly from woofersetc.com
Good price at Euros exchange and fast shipping from LA to Madrid (just one week):













This sub is a beast for a 8" cone. It really delivers power in a wide range. If it's well tuned the overall system is very balanced for all kind of music (I listen mostly rock)

Hope you like it!

did you just hook it up to the existing speaker wire?

Yes, the signal is taken directly to the wire that went to the original sub.

In the UK forum of audi-sport some users asked me to be more specific. I'll try to have a little diagram to help you out if you want to do something like this

I'm interested too

Hello,

Well, no diagrams, I'm sorry. I'll try to explain: the original wire to the Bose sub has been directly plugged to the "High level" connector of the amplifier (the white one in the picture below). As you probable know, not every gear features this kind of connector.

The amplifier has a dedicated wired knob to control the bass intensity but it's also controlled by the bass leve found in the RNS-E head unit.

I hope that helps! =)

thanks, that should help. where's the amp mounted?

[galanot]

The amp is mounted behind the back left panel, below the speaker. We had to cut a little bit to get the amp inside, but went smooth and had enough space. Note that there are smaller amps out there.

Just a tip regarding the connections: the original Bose amp give power separately : 1. to the front speakers (central, tweeters and front door units) and 2. to the rear speakers and subwoofer. Now this amp is feeding the same except the sub that was removed. In fact, the new amp takes the signal from the old one (that was used to feed the original sub).

How many watts did it have?
