Protection Function flashing with error code E-2

I am running 2 XXV-03A Mono pushing 2 12" Kenwood Subs each and 1 XXV-02A 4 channel running my highs. I have been running the system for the past 2 months with no problems, all of a sudden the protection function light for one of my XXV-03A Mono's started flashing and now it keeps flashing with the error code of E-2 on the display screen. I have reset it and several times and the E-2 or the flashing will stop. Please help!!!!

Re: Protection Function flashing with error code E-2

I do believe that error is a short between the positive and negative terminals. Check your wiring and measure with with a ohm meter, it should be more that 1, if not 2 ohms. With the wires from the speaker termanils removed and the amp off check the condinuity between the two terminals, there should be none...if you have some that thats where the short is occuring and work needs to be done on the amp to fix the problem

How to wire a crossfire vr602 2 channel amp at 4ohm and 2ohm

I would be more worried about the amp than the speakers, those subs should handle the watts with no problem. The problem will be in the amps ability to remain working with a bridged 2 ohm load. It may not even stay on without going into protect mode with a 2 ohm load. If it does stay on then it may get really hot and shut off from the heat off of the Mosfett Transistors, or it could burn the Mosfetts from driving them too hard. Basically it's your choice, run your amp hard and gain more volume or run it with slightly less sound and have a cleaner sounding more stable amp that will stay on and have less chance of being damaged. If it's not loud enough the best thing to do is buy a different amp that better suits your needs and fits the application. In your case a 2 ohm stable Mono amp is going to be your best bet or a 4 channel amp bridged into 2 channels and run with 4 ohms on each channel. Or another exact matching amp like your 2 channel amp bridge them both and have each powering 1 of your 4 ohm subs. I used two VR mono amps to power my two 12" 4 ohm subs for a few years

In my display is says 3-03 when ever i plug in my rca cables and no sound comes out?

From Page 7 of your manual... this is indicating a grounded speaker wire (blown voicecoil).

It has shut down to prevent damage. Disconnect the speaker wires from the amplifier and power on the amplifier again. If the error persists - you will need to have the amplifier repaired.

Check the voicecoils for proper imedance.

The subs aren't pushing out bass.

Hello crobins2,

The Kenwood KAC-6202 2-channel is only rated for 60 watts RMS per channel into a 4 ohm load. That just isn't much power for a pair of 12" subs. Even the bridged output is only 200 watts into 4 ohms, still at the low end for a sub, much less to share between a pair of subs.

Assuming that your subs are 4 ohm, you could probably get more sound by driving just one of them on the bridged terminals. But to get the best power with what you have, connect one sub to each channel, set the filter switch to the far right (LPF), set the operation switch to stereo (both channels driven), set the filter frequency (Hz) to 100 or lower, and adjust the input sensitivity as far clockwise as possible without causing distortion.

But, to do the subs justice, you really need at least 300-400 watts to share between them.

Hope this helps.

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.

I was given a kenwood kac742, what do i have to do to hook up 2 subs to it tom

You need:
1) 2 4-ohm subs
2) Appropriate enclosure
3) Amp wiring kit with RCA's

Connect each sub to a separate channel and set both mode switches to "MONO" (center position). In 2-channel mode, this amp is only rated at 80 Watts RMS, so you need relatively small and efficient subs. I'd say nothing bigger than 8" or perhaps 10". Rockford-Fosgate P1S48 (8") and R1S410 (10") will work OK with 50-150 watts RMS. Some others will also.

KAC-9104D output terminals

ok i have the same amp and 1 2ohm dvc sub and was woundering the same thing but from futher research and askin sum xsperts. What i found out is that it is only one channel and even tho there are 2 (+) and 2(-) they actually connect inside the amp makein it one . so if u wanted to wire sumthing parralel u wouldnt have to hook wires from one coil to the other on the speaker , u can just hook it up to the amp. so basically both +'s and negatives on the amp are actually one within it so all the power if you only use one set of them and if u wanna add more subs its just easier to add to the amp by using the xtras .

Help me...

If you had 4 single voice coil speakers you can create either of those 2 ohm or 4 ohm setups. If you run 2 of them in parallel you will get the 4 ohms. If you run 4 of them in parallel you will get the 2 ohms. In parallel I mean that you connect the positives together and run them to the positive on the amp and the connect the negatives together and run them to the negative on the amp. Let me know if you need more help. Good Luck.
