If you had more power on a four chan, you could do active, it would get louder, but you need to becareful not to fry that tweet.

going active will get you louder. i did it for about $100. each speaker gets its own channel and you hook up a crossover inline with the RCAs. it will get you louder and sound a lot better doing it.
i dont know the JBL set you want but a lot of sets can take more power than they say. i ran 150w to the pioneer PRS720 for over a year. its a 50w comp set and it handled it just fine. in fact that set was around $250. look into them, they sound GREAT and everyone ive seen who owned them was amazed at how good they sounded.

4 realz?

i'm giving my alpines 180 watts (rated 100) and if i crank it up too high they start to pop

how much power can tweeters usually take? 30-ish watts?

not too sure myself. but, the benefit of a good 4chan, you can turn gain down low...

hmn that high pass only goes up to 500Hz. would that be a problem?

okay so here's a newbie question: how would powering comps actively make them louder given equal amount of power?

one of the few class AB amps i've seen with phase control. would this come in handy?

 

[subzero 5,000+ posts]

better than switching wires to find out. it does come in handy.

because you can fine tune the freq response and amplify the range that suits your needs. Active is not always better. You could just get a really nice two channel or channel bridged to get you more clean power. I would put 250rms to those and leave it at that. 250rms x 2 chan. @ 4ohms per chan. That is the amp you need.

Don't start on your next paycheck. Keep reading more, and if you have the ability to save money; do so. I read around this and another forum for a long time before I started buying stuff. This was my first install, and did a 3-way up-front. Not hard to do, took me sometime. The wife complained about the seats being out of the car for over a month. Go active and never look back. Get you some efficient speakers from here partsexpress.com or madisound.com. Spend 100 on speakers at either one of them spots would equal you spending 250 for some branded speakers probally made by the same shop.

Hmn, so you're saying... to hell with buying a component system, build your own?
