I don't know shiat about amps.... but here is my radio

With a decent amp, how do you think that would sound in a Max?

what's your budget? we can better guide you once that's established.

 

Like $400 or lower? I don't know how much a decent system cost really...

My radio is fine and I have one of those old school Mercury amps 50x2

So I need a amp and a speaker/s.

I don't want much drop just a upgrade over stock....

Subwoofer or a pair of 10s in a box whichever is more efficient.

 

Check the FS section on here.

 

Are you planning on using your Mercury amp on the subs? BTW, what is a Mercury amp?
You want cheap, try Craigslist. Out here in Denver it is flooded with sub boxes, amps etc.

 

Spend for quality up front. It's cheaper and less frustrating in the long run.

 

Do you have any cheap brands you guy recommend? links, anything of that nature?

So you have a Kenwood head unit, stock door speakers and an amp?

Is this your amp?

 

yep
