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

Alright first suggestion is to get a different amp. Cause for one a mono amp is meant for just one signal (one speaker) also you need to make sure that you get an amp that is powerful enough to run the subs. You need to find out what the RMS of both speakers is. From just a few moments online I found a Kicker 12" Comp. subwoofer has an RMS of 50-150 watts. So you need to find a 2-Channel amp that has at least 300 but you should get one that has at least 400 just to be save. You can find a Dual 2-Channel 400W amp at Walmart for $55 and get the 600W wiring kit for $25. You should just use the inside speakers for mids and highs and allow the subwoofers to run just low frequencies. That way everything will sound correct, and not ruin your subs if the do not have a voice coil in them. It's fairly simple to set up a system with an amp and subs, you just need to make sure you have the right parts.
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.
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.
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.
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 .
