fitting subwoofer with built in amp to RNS-E (non-bose)

[8900120d]

hi, im a total noob when it comes to sound systems, i have an audi a3 2010 with an rns-e satnav, im looking to buy this:
Halfords | VIBE Optisound Auto 8 Active Underseat Subwoofer Enclosure

its an underseat subwoofer with an amp built in.

but im confused on how i will connect it up to the rns-e as it doesnt have rca connections at the back.

any ideas on how i will wire this? do i have to disconnect the rns-e amp?

thnx

Although I'm not sure if this sub is a good choice. Yes it's good as you are a novice at sound systems but I don't think that will sound that good. you'd be better off gettin a stealth box and and amp in the long run. A little more work but probably sound a lot better.
Or if you have time make a fiberglass box in the area where your spare wheel goes. Then measure the air space available, and buy a subwoffer that is designed for that air space. Yes it does take a little time but there are tonnes of tutorials on how to do it and it's not really that hard just a little patience. I was in your postition once and thought exactly the same about getting an underseat compact sub. Glad I didn't bother and went the other route.
