Too much power?

[b34tBoX 0]

Old system:

Some cheap Sony deck

Infinity Kappa 5.25" components (2007) - KAPPA50.7CS

Infinity Kappa 6x9" 3 way coax (2007) - KAPPA693.7I

Infinity 10" sub - KAPPA PERFECT 10DVQ

MTX Thunder564 - 4 channel

MTX Thunder421D

I will replace everything and all ready have:

Alpine 9885

12" Fi BL - Dual2, Cooling, Flatwind, Daily

Hifonics ZXi 6406

Hifonics BXi 1606D

I was going to use the 4 chan. Hifonics to power the new Kappa 2008 speakers since they are 2ohm, but just decided how much I hate my current kappa's so want to do something else.

Wanted to get:

and

http://www.woofersetc.com/index.cfm?fuseac...Product_ID=3078

For the speakers which are 4 ohm.

However the Hifonics 6404 I don't think would do a good job doing all 4. less than 85watts a channel.

What I could do is bridge the 6404 and 421 to power the speakers, but then I would be sending each channel over 300watts.

Should I pick up two 2-chan amps instead?

I was thinking about getting 2 Hifonics ZXi 6006. which would give me 150watts @ 4ohms at best per channel.

Buying 6x9 components is a waste of money.

Just buy a decent set of front components, bi-amp them and than if you "need" rear speakers for fill, buy co-axials of the same family of speaker and run it off of deck power.

[audio-neon 34]

also the 1606d will only give you around 1500 watts rms. I would atleast buy the 2000 watt model.

As I am a little unclear with what you are asking. I can tell you this based off of the topic, you don't need to run speakers near or at or even over their rms wattage ratting to get good performance. As they are a good price, their quality has seemed to be in question, the Hi Fonics amps that is. One member here, ///M5, is a proponent of using the same budget and looking for high quality/featured amplifiers used.

Yeah I tried to provide as much info as possible.

Basically, I have my current "old" system installed, and I all ready have the new parts to put in, but I decided to not get the new kappa speakers which would have worked fine with the 6404 amp, instead I'll be getting the CDT's (or just the fronts), but either 4 channel amp would either underpowered them if ran in 4chan mode or if I used both and bridged them they would provide 300 watts a channel, which I assume would not be good to do.

Anyways, I think I need to sell some stuff off I just bought and re-do what I had planned.

85 watts/4 would be more than enough for a mid-bass/tweeter

Even if the components are rated at 170?

Would it still be OK, or could I bridge the amp to provide 300 a channel but control the gains?

Or should I pick up an amp rated at say 200x2@4ohm

Edit:

I think I'll just get 2 Hifonics ZXi 6006 (2x150 @ 4ohms) to power these CDT Speakers:

6.5": http://www.woofersetc.com/index.cfm?fuseac...Product_ID=4691

6x9: http://www.woofersetc.com/index.cfm?fuseac...Product_ID=5435

I'll stick with the 1606 amp for the sub, that can at least be replaced easily if I think I need the extra power once I finally here this system.

From many recent reviews, a good number of people have reported back that that series of amplifiers do not do ratted power. Plus just because they are ratted at 170 rms, does not mean you need to send that much power to them. A quality 50x4 or 100x4 amp with a half decent crossover would be plenty.

I wouldn't buy the Hifonics stuff if it were 15% of the price that it actually is. I still don't understand what you are actually asking either.

Thanks for your help guys. It was pretty confusing to follow I know, but I think I'm ready to order now, and just sell my old stuff.

I am thinking of getting just a 2chan amp to power the fronts, and let the deck power the rears as audio-neon suggested.

Am thinking this amp:

to go with these speakers:

http://www.woofersetc.com/index.cfm?fuseac...Product_ID=5435

I'll install the Hifonics 1606D that I have to power my 12" Fi BL, and see how it performs before I consider replacing it.
