Newbie with a question

I see this ending badly

Your right

the alpine is a better amp so something else has to be at fault....

That's what I hear and read. I was so excited when I bought it and couldn't wait to hook it up. Now feeling disappointed and scratching my head.

what rca outputs you got on the HU volt wise?

How do I find this out? Unit is Kenwood Excelon x993 Crutchfield PDF spec sheet say's 4 volts for the unit. Is that what your asking for?

4v is good, something ain't right though thats for sure wish I could be of more help...

I am suspecting the amp itself as being bad but to much time has gone by to take it back to bestbuy troubleshooting. Its 6 months old.

try swap it for something that'll give you the pwr you need

or just keep using the kenwood

He was runnin the cvr at 2 ohm bridged on the kenwood. That will burn the kenwood up.

Correct me if I'm wrong but this may be the problem

The minimum final load impedence for the kenwood bridged is 4 ohms which creats a 2 ohm final load right? Which wired like that is giving out 270 rms x 2. Thats 540 rms. And he was bridging it at 2 ohms creating a 1ohm final load which is probably doubling that so if I'm correct hes ripping close or more than 800 rms out of that amp. So of course it would be twice as loud and sound louder and cleaner but will destroy the amp or sub or both before long. Right?

When you run a DVC sub on only one coil you cut the power handling of the sub in half, plus you induce a current on the other voice coil, which is wasted energy.
Your best bet, as has been said, is to run the sub on the monoblock amplifier as it's designed to run the sub. Use the 2 channel to make your front stage come alive. ;-)

Read over my last quote n tell me if I'm right.

bbeljefe is correct, wire it properly or risk of cooking your gear

Read over my last quote n tell me if I'm right.

The Kenwood amp is rated at 2Ω per channel so a 2Ω bridged load will create a 1Ω load per channel. Since the amp cannot handle that load, it won't be twice as loud or cleaner but it will make the amp heat up to the point that the smoke will come out of it.

That said, the system will be louder and distortion probably won't be audible until the amp begins to seriously deteriorate but, technically, it won't be "cleaner". The reason it won't be twice as loud is that the power supply isn't capable of supplying enough voltage and current to the final amplifier in order to make double the power. What will happen is that voltage won't increase when it needs to and as a result, the final amplifier will draw more current, decrease efficiency (make heat) and ultimately, fail.

But yeah, you're right for the most part.

that little kenwood amp looks half decent

And don't want to do that so now the Single Sub with both CVR vc's in series with measured resistance of 8 ohms. Sounds great so I am okay with the KW at this setting. Now for the boat.
