honestly, people who say things like Infinity and such make the best speakers money can buy , make me laugh.....

the main question here is budget. because there are speaker companies that don't spend lots of money on marketing, but into their product and it shows. for instance: Hybrid Audio. won the 2009 sq world championships............ amazing sq speakers, Get quite loud as well.

but honestly the install will make alot of difference in what you do.

and what I mean by that is, IF I took and sound deadened the entire car, and you doors etc. built some door pods so phasing was spot on, and had good quality clean power, 99% of what you put into your car will sound 500 times better than it would by just throwing some random speakers someone told you to get.

so again you budget will affect the overall output, clarity, performance, and "thump"...

you could look into doing something with say an 8" midbass. a 4 inch mid, and a nice tweeter, and you get a sub like effect. but most of the companies that will make something along those lines are not cheap.

so again, just because the company isn't known say like alpine, jl, rockford fosgate, infinity, pioneer, jbl, and so on, there are speakers that will run circles around these companies, for around or cheaper than the cost of these said brands,

they woop them in not only cost, performance, but also customer service, and as you build a larger audio system, or get more indepth with the systems, you quickly realize install, and customer service goes a long way.
