SOURCE: amp getting really hot

If depends on what the amp is rated to run. If it is only rated to run 2 ohms x2ch then it can only run 4 ohms x1ch. If you run it at 1 or 2 ohms that is too low, too much current, and it will get hot and eventually blow up under hard use. Some quality amps can live that way, and it depends on the sub and what frequency you are running it at. For normal use I would not recommend it. Wire to sub at 4 ohms x1 (or 2 ohms x2ch) for that amp if that is what it is supposed to be at, I'm not sure from your description. Also enhance cooling of the amp if you can, I run fans on mine if they have a heat issue. Warm is one thing, hot is another and not good for amp.

SOURCE: amplifier loads

Hello ronnieyannon,
A single 4 ohm speaker wired to each channel, like you have them wired, presents a 4 ohm load. And it appears that you have them connected properly. The 401s is only stable to 4 ohms when bridged, so if you were to parallel the 2 4 ohm subs in bridged mode, the load would be 2 ohms and the amp would most likely overheat and go into protection.

I'd wire them the way you have them wired.

Each channel of the amp outputs only 100 watts into 4 ohms. That is adequate for regular full-range speakers, component speakers, mid-range drivers, and even some small subs. But it is a little low on power for most subwoofer applications.

Hope this helps.

SOURCE: installing two amps

No, thats what you don't what to do. Even if you have 2 matching amps you don't do that. Every amp puts out different, and for 2 subs, you want to play at the the same time. If your only running 2 10's, I personal would just run the alpine (it's a mono amp made especially for subs) thats plenty for what you have. make sure you bridge them to get the full response. And your other amp i would use for your highs or mids, but run it @ stereo , which is 300 w @ 4 ohms. (Note: 600w @ 2ohms would be bridged and would play in Mono)

Building Competition stereo's is a big hobby of mine.

SOURCE: can i hook up my sub if it's wired to a 2 ohm and my amp is 4 ohm

Hi martineztag
You should never connect a load of an impedance less than the min the amp is able to drive. This can have disastrous consequences that may easily result in failure of the amps output stages. You need to use a different configuration that does not overload the amp in this manner for safe operation.

It says 75 watts rms per channel. what would the power,when u 2ohm load each channel?

If your amp is 2 ohm stable it will do 75 rms to both sides maybe a little more.

I cannot find the specs or user manual on the JVC archived items list. A few sites want to charge $10.00 for the user guide info, but I think that is too much to charge.

How do i bridge 3 subs to a 4 channel amp

My information shows the XM-1652Z as being a 2-channel amp. It will not be stable below 4-ohms in bridged mode. For best power, your subs will need to be 2-ohms with all 3 wired in series. This will present a 6-ohm load to the amp. After wiring the subs in series, connect the positive speaker wire to one channel (+) and the negative speaker wire to the other channel (-). For the 1652Z no other wiring is necessary. For subs you will also want to set the LPF (80Hz) switch to the "ON" position (to the right).

Keep in mind that the rated output is only 400 watts RMS at 4-ohms in bridged mode. That's kinda wimpy for 3 subs. You would probably obtain better results from two 2-ohm subs, each connected to a separate channel. That way each sub would be getting 200 watts RMS, still low but there's lots of good subs that will sound pretty loud with 150-200 watts
