I have had so many problems with this amp I'm just ready to throw it out the window. I have blaupunkt (if that is how you spell it) in the back which are four ohms speakers. I have Kappa perfects in the front with are four ohm speakers. When I have my Alpine door speakers in the front the amp is fine. When I hook up the perfects the amp overheats and shuts down. The speakers are brand new, this is actually the second set of speakers I've gone through. I thought it was my Three.1 eq but I took it directly to the head unit and still the same thing. Anyone have any suggestions?

Have you tested the speakers with a multi meter to make sure they're showing a 4 ohm load?

Are you certain the Kappas are actually 4 ohms? The newest models are 2 ohm loads.

Not only that, but why bash Eclipse amps? Is this the amp you are using? I'm lost...

It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

Yes its an eclipse amp. With a DMM the front speakers are showing 4.5 on each channel. When I have the Alpine door speakers in the amp is fine. When I only hook up one door ( driver or pass.) the amp is fine. I've been fighting this problem for a while now. I'm ready to give up on Eclipse amps.

I'll give you $100 for the speakers and amp right now. Fed Up With Eclipse Amps -- posted image.

Are the Kappas coax or components? Are you using the crossovers? Post some model numbers, please. How's the amplifier's gain set?

Its the Kappa components, I'm using the crossover that came with them. The amp gain is set correctly. They aren't even half way up.

Model year 2005 Infinity Kappa components are 2-ohm impedance. You may read higher DCR, especially through the crossover, but they present a nominal 2-ohm load on your amp. Your gain is probably too high for them. How'd you decide that "half way up" was the correct setting? Again, how about some model numbers, and what's your HU?

Well I tuned my amp like this...turned the hu up 75% of the way....balanced the front and rear speakers. Then left the gains there. After tunning my amp I looked and the gains aren't pass half way. The speakers are Kappa Perfect 6.1's and the head unit is the Eclipse av8022

OK, the Kappa 6.1 set is a 2004 model so they are 4-ohms. The AV8022 I believe has the standard Eclipse 8-volt pre-outs. Again, depending on your amp you may simply have the gain too high. I suspect the Alpine speakers present a higher net impedance which allows your amp to stay on is probably what's going on. What's the amp (MAKE MODEL NUMBERS FOR EVERYTHING PLEASE!) and is there anything else in the signal chain?
