I saw a pair of Hertz tweeters in my local pawn shop today for $25. I thought it was too good a deal to pass up so I grabbed them. But now I am kinda stuck because i am not sure what to do with them. The tweeters them selves look brand new. They are Hertz HT25, the little plastics ends are still on the wires, and they say 4 ohms on the back.

But my current component set is Alpine type-S(I hate them with a passion), which doesn't come with a regular crossover, so its not like i can just hook them up and go. I know I can run active, but that means getting both another amp and a new head unit as my current (Pioneer DEH-7200HD) doesn't run active.

So basically what should I do? Do I just have to pony up and run active? Or is there any way I can get a decent mid-bass and crossover and save myself some dollars?

Buy an external crossover and a 4 channel amp, or splice the tweeters in past the in-line crossovers on the alpines, or buy a 2-way crossover for 4 ohm mids and 4 ohm tweets. The tweets you bought are probably fake, fyi. Take a pic.

The tweeters don't look fake. They are heavy and well built. Also I looked at another on here post of the same tweeters for sale and the came with all the same mounting hardware as that listing.

check out parts express too...you can even call them, tell them what you need and they sell everything you need to build them. You can solder?
They sell complete crossovers also

I really don't want to have to build my own crossovers. If i run active what will it require? An active capable head unit and another amp to run the mids?

If you run them active, start with your tuning really high (around 3.5 - 4Khz) and move down from there. That way you don't burn them out. It takes about 1/4 of the power for your tweets compared to your mid-range or lower. Chances are your ears will bleed before your tweets do. ;)

You can either use an active head unit or an amp that is active capable. Tuning at the head unit is usually "better" but having a amp that is active capable can sometimes be cheaper if you already have a HU you want to use.

god your whiny.lmao.
just buy some passive crossovers and call it done.
if you want to go allout, then prepare for some heavy work. its not that difficult to wire a crossover into your front stage.
