I don't really know much about these so I'm kindly asking for your advice. 
I'm after buying an amp + sub for my Clio, so I have a few questions. I have a budget of about £300 for the lot.
1. I've heard that you can get amps which provide a high amount of bass similar to a sub would and still do their job of increasing the volume, is this true? If so what type of amp would I need to buy?
2. If I got a 3000w sub would I need a 3000w amp too? What would be the minimum?
3. Would I be able to get and install JUST the amp and sub without getting new speakers for the doors etc. in my Clio?
4. Is it better with one 3000w sub built into a box or two smaller ones that equal around the same amount of wattage built into one box?
5. Does the wiring kit wattage have to match both the sub and amp watt levels, or can it be under/over?
All advice is welcomed and greatly appreciated.
