I have a 2003 dodge 1500 and I just got a Kenwood KDC-HD545U and I want to get a good sound system and I don't know what speakers, subs, and amp I need if I can I want to put my subs under my back seat and how much will it help to have 2 subs

 

Price depends on brand and if you buy new or used. I have mtx 10in speakers in my truck and i paid 200 for the box and speaker...These retail for 450 on crutchfield.

You can also check your local craigslist to see if anyone is selling these items or check the classifieds on here i Believe someone is selling all there sound sytem

I bought my box on Criagslist, $30. Got two Memphis 10's, and an amp, from a pawn shop. I think I paid less that $100. And the sound is awesome, really rounds out the system sound. Imma upgrade them door speakers next

 

@ jp246 - all this really depends on how deep your pockets are.

If you want to do a double DIN head unit in the dash then LMK as I make the bezels for them

But on average........

a Foxbox for under the seats is $180
F&R door speakers - $100
RCAs/power/ground - 30-50
amps - 200-300
Kicker 12s or Aline 12s - 75 each

However, an alarm system and Jimmy Jammers in your doors to keep thieves out should be first.
