Will there be a difference in sound quality if I run my front components plus add on tweeters(both rated at 4 ohms) at 2 Ohms wired parallel? If so, how much worse? My other option is to buy another amp just for the tweets, I would prefer not to do this. The amp in question is a Rockford p8004 which will give 100 watts @4 ohms and 200 watts @ 2 ohms. The sound now is great, but I have a huge high frequency craving, hence the add on jbl power series titaniums.

how exactly are you planning on wiring these? You would need some sort of crossover for the tweeters, or you're going to blow them trying to play them full range.

If you're planning on wiring them with the tweeters of your components, it will change the crossover point for the components.

Adding a set of tweeters will not change the load for you to need to worry about it.

to 75grandam, yes it will have it's own x-over and it will run directly from the amp.

to slow/n\low; the tweeters are rated at 4 ohms just as the components are. Should this not create a 2 ohm load when wired parallel. The components are jbl's power series 6.5 2-way and their 1" titanium dome component tweeters. Basically, the front will have 1(6.5)midbass and 2(1")tweeters per side. I am a sucker for high frequencies.

^ The Load presented to the Amp with not be the same as if they were woofers.

Nothing to worry about. Wire 3 sets of tweeters and enjoy your highs [img]tongue.gif[/img]

Ok maybe not 3 sets, that could get shrilly

I would be more worried about the tweets getting too much power as compared to the mids...so resistors must be employed as you probably know, to balance out for linearity...and if you use the resistors, now the load the amp sees will change with frecuency...so maybe u wanna look at an impedance balancing network....have fun!

Honestly though, amps are so cheap these days and with decks coming with built in x-overs most people no longer resort to building by trial and error using hand built networks...quality parts are expensive and tuning is, well...a ****h

Unless....you are doing the whole thing for the fun of it and wanting to learn, go for it
