Default How to Power Components?

Here are my components:

http://www.sounddomain.com/sku/DEI36065

Sensitivity: 89 dB
Frequency Response: 58-25,000 Hz
Recommended RMS Power: 125W
Peak Power Handling: 175W
Impedance: 4 ohms

Here is the factory book on them:

http://www.directeddealers.com/manua...50_2_650_2.pdf

On the 14th page, it says that for the 650.2 125 rms/175 peak; tweeter 100 rms/160 peak. All of this is at 4 Ohms. Here is my amp:

http://www.sonicelectronix.com/item_3030.html

125 watts x 4 chan. @ 4 Ohms
200 watts x 4 chan. @ 2 Ohms
250 watts x 4 chan. @ 1 Ohm
400 watts x 2 chan. @ 4 Ohms
500 watts x 2 chan. @ 2 Ohms

Should I give a channel to each tweeter and midbass--use the amp in 4 channel--or bridge it and run just 1 channel to each crossover--use it in 2 channel?

Are you more interested in sound quality or volume?

Higher wattage rating does not mean that its a better amp.
To drive component sets I would look into a quality amp that will last like a rockford fosgate or similar brand.

I have the amp, just want to know which way I should utilize it. I have had Hifonics amps for the last 7 years, and have been more than happy with their product. Just decided to upgrade.

Run: 200 watts x 2 chan. @ 2 Ohms

Bridge the components to one channel and tweeters to the other channel.

Distortion is what kills speakers. Too much clean power doesn't kill speakers.

Levi,

Wouldn't bridging it put the amp at:
400 watts x 2 chan. @ 4 Ohms
500 watts x 2 chan. @ 2 Ohms

I had thought about running the amp 4 channel and getting some midrange for the rear seats since I have this DVD HU now:

my question is since the component set is 4 ohm, woouldnt you be limited to 4 ohm amp configurations? it appears you can choose from either 125x4 or 400x2. and if that is the case i think you may be better off going for the higher wattage and using the component crossovers. as was said, more clean power wont hurt, its just distortion that kills. i have some coax speakers with similar wattage ratings to yours, my amp puts out 100x4 RMS and i think i could benefit from alot more power.

Yep, that's correct. I glanced too quickly.
If it were my stuff I would have no issue putting it at 500 watts x 2 channel @ 2 ohm. As long as you set your amp gains and HU properly (i.e. not playing and amplifying a distorted/unclean signal from the HU) it'll be fine.

It still boils down to too little power is usually the culprit for blowing speakers. People usually turn up a volume to a desired volume, and if the amplifier does not have enough power, it will clip prior to reaching that volume, hence cause damage to the speaker. So is the lower power responsible, not directly, but in the end, a stronger amplifier would have put out cleaner power to acheive the desired volume level.

Yep, I would do it so that the components are getting b/w 200-250 watts.

What goees his also is that the comps will only get the full power of bridged channels if I do not any speakers in the rear passenger area--should I run speakers there? I did not do so on my current setup, but this time I am running a DVD setup, thus I thought I may need to add some drivers or some full range in that area???

I'd just use your front componets and a rear fill sub.

How about wiring though? What do I need for the amps? One amp is 2000 rms at 1 ohm/4000 peak, the other 1000 rms/2000 peak. JVC 7010 DVD HU, JVC 12 Disc changer on the front side (already have adaptors, etc). The subs are 2 ED 110V.2 1000 watt rms 4 ohms (wired for 1 ohm load), and the components are 4 ohm Directed Viper 650.2's receiving 400 watts rms at 4 ohms. What guage wires do I need? What blocks, other stuff?
