About a week ago I decided that I wanted to add subs to my car. So I bought subs and an amp and they are being shipped. Now I just need a new head unit.

My budget was about $100 and I really have been happy with the stock deck. The issue is that I feel like everything in my price range would be a downgrade from stock besides the equalizer and the aux input.

How much would I need to spend to get an equal or better deck?
Does anyone have any recommendations?

My car is a 2003 Toyota Camry

For anyone who is curious I bought
2 12" subs [ AlpIne sws 12d4 ]
1 1200watt amp [ Hifonics ZRX1200.2 ]

I think they are pretty good choices for my first system :]

Anyways. Thankyou for anyone who helps
