If you get a correct amp to push them and do the neccesary electrical upgrades to handle that kimd of power it will be night and day diff..whats ur budget and are u willing to upgrade to a ho alt or a extra battery?
Capacitors are junk ..extra agm batteries and ho alts are what you use at higher power levels..with that budget u wont be able to do what u want with the hdc3 10s...but here is what i would do ...buy 2 soundqubed hds310s they are 139 each ..have a custom box designed and built for them ..then buy a ppi bk1800.1 they are 200..run 1/0 wire thru the car and do the big 3 and replace the battery under the hood with a good agm ....set the gains correctly on that amp and you should be in pretty good shape..and miles beyond where you are now..all that will be at or or a lil over ur budget depending on what type of batteries u can get in ur area...do u have a sams club local?
All the current bk models are being discontinued so its 199 now ..new line coming out soon..the bk line is solid i run the bk800.4 on my mids and tweets .gobs of power
Needa around 3 cubes after port and sub displacment..and get a g34 duracell agm from sams if u have one in the area they are 130 bux
The 800.4 is almost same size as the Bk1800...u can build a amp rack and stack them on top if each other like i did with my aq3500 takes up no more room
Yea that way u would only be taking up around 4" of height..very simple to make
