I just installed 2 12 kickers running to my double din touchscreen head unit Pioneer AVH p2300 and 1600W SSL Amp. But it would play for half an hr and then after that it starts going into protected mode. Is possible due overheating, wiring or is it dead? But when I let it cool down for 10-15 mins I can bumping for shorter time.

How can I tell if it the overheating issue because when I touch it I know it warm I can keep my hands on for least 7 seconds.

I've checked my grounding wiring it shouldn't have any looses wiring.

Oh and by the way I'm running 2 channel amp with 4 gauge wiring kit I'm not running any wiring to speakers only amp to sub and radio. I don't have Bose speakers... I don't think since I don't see speaker up-top of my back rear window.

My experience when a amp turns off then back on after cooling.. its overheating

Assuming the subs are about 350RMS? That amp just can't handle it. Likely the amp can put out about 750RMS of clean power at its peak which simply is not enough. Turn the input down and see if it helps otherwise start shopping for an Infinity amp. The 611a should suit your needs perfectly. Ive had it for years and in the southern summer heat it has never let me down powering 2 12's

Adjust your gain correctly. If after doing that you are not satisfied with the output, start looking for an amp with more power, as mentioned above.

Okay guys... I just got a replacement amp been working solid but then just the first time after 2 days used it went into protect mode this morning soon as I start the car and bump the song at high volume soon as the bass hit. But then I restart by shutting off the car and turn it on then it working haven't had gone to protect mode lately. Do you think it the current my car battery can't handle that much power?

But so far there was no clipping sound anymore so that was one of failure amp. My friend told me capacitor isn't worth it.

What is the total impedance of your speakers?

Check your ground to make sure it's both secure & a good grounding point.

Garrettz459

To be honest I had a guy to do it for me. But from what I know my speakers isn't running to the amp only head unit and to my subs. How could that impact my door speakers? But it did happen again when I folded my seat up and I realize one of the power wire was loose and got snapped out from my amp just had to screw it in tighter and test it again then I was being bumping music for about half an hour all the way back home no shutdowns or clipping.

The car is still quite new so it takes awhile to put more audio stuff into my car... sometime soon I'm planning on getting some goodies!

When I said speakers I was referring to your subs.

Glad you got it figured out. Many times it turns out to be an installation mishap.

Oh my 2 12 kickers is using 2 Ohms load running 4GA wiring to my amp 2 Ohm at 600 RMS.

So far it currently working so far no protect mode yet... if it happens again I'll let you know.

Garrettz459

Okay it been 2 days and I kept forgetting to post here about if I get a protect mode I would post the result well.. guess what it went on again and again once awhile even sometime all the time.. I can't even get pass 28 volume out of 50. So most people my friends have said that amp cannot handle my subs woofer at 2 ohms. So I guess I'm going to buy a Kenwood 1800W 900 RMS @ 2 Ohms! What do you guys think?

You're running bridged into 2 ohms, aren't you? You can't do that with that amp.

Garrettz459

You're correct. I can't this amp is piece of crap I've shouldn't bought it so I'm gonna sell it on craglist for $110 to somebody who dumb enough to buy that amp like I was before..

I just ordered a new one Kenwood KAC-9105D Class D-Mono 1800W

900 RMS @ 2 Ohms Stable

people have said this kenwood is very stable with 2 Ohms. What are you thoughts about that amp since I already purchased it.

I know it only one channel amp and I'm using that for sub woofer only but someday soon I'm gonna get another amp for door speakers and mids/high. The car is still new only almost 2 months old lol.

I know Kenwood has always been a popular brand for any audio equipment.

That amp should do. Dual voice coil speakers correct? You will need to wire your voice coils in series and the speakers in parallel and that will be a 2ohm load and as long as you dont turn the gain/input all the way up you should be fine

Garrettz459

Hmm... I don't really know anything about wiring voice coils in series or parallel. I got the 2 12 kickers came with enclosure box I had the guy to install the system for me at professional shop.
