Ok, I have been looking in this forum for few days, trying to figure it out system for my car. I have learned a lot but still there are some questions I can’t answer, every time I learn something new there are more questions and it never stops so if some pro could help out a newbie it would be appreciated.

I want to keep the HU, change the interior speakers and add a sub or two.

My budget is about 1k but if needed, I can still add couple hundreds.

The question is
1) What is the size of front door, back door and rear deck speakers?
2) Which speakers to buy for the front door? Memphis/Eclipse/Alpines (Type R/S)
3) What speakers to buy for the back door?
4) What speakers to buy for the rear deck?
5) What subs to buy? I have seen in audio store a lot of subs are Puncher/Kicker/Eclipse

6) What other pieces/components would you need? (wire, dynamat extreme,spliters, crossovers etc.), I am trying to buy stuff from Ebay and then have some1 install it in my car. Don't want to be charged the full retail price when buy from store.

7) Everyone has different taste and needs but I would like to know how you guys select which product to buy, what do you take inconsideration when you make a selection and what other product you considered instead this one, and why you picked what you picked.

8) Also I am not sure what amp to buy. Some1 told me that there is double 4 channel amp (like 8 channel) which could power my interior speakers and 2 subs, but my guess it’s pretty expensive, 2 amps would probably cost cheaper. Kicker, Memphis, Extreme, Eclipse are some that I would prefer.

9) Now with the amp and speakers imp not sure what the Ohm stand is for, some speakers say they are stable at 2 ohm others at 4 ohm, what does this all mean? Can I please get more information on this?



Thanx!!
