I heard Sony's and Pioneer's HU are quite decent for budget upgrades. But don't really know much about the model to go for. Can visit
Sony Website to compare prices. But now I heard the models are getting old, do go down Sim Lim Tower and check things out.
Anyway, got a question here I like to ask everyone. Let's say you only have 500 dollars to upgrade your stock ICE, what would you do (first)?
1.) Change HU and a nice front speakers.
2.) Invest in a 2ch-amp and a decent pair of front speakers.
3.) 1ch-amp, a pair of tweeters, 1 sub-woofer.
4.) Just a decent HU.
