JRoweMDN I am not sure there is room. I know some people have mounted powered subs in the console. Just have to measure and see.

I did think about that.. Ive been seeing a lot of people mounting amps under the dash, I don't see why I couldn't mount a small powered sub under there

Mindlesschunk I'm about to buy a crutchfield powered sub.. Heard they go under the drivers seat and add a lot to a factory system. Obviously not gonna blow your ear drums out, but that's not what I want..

Thinking about taking industrial strength Velcro and mounting under drivers seat? Anybody have one?

tol1l1yboy I was told that either a Kenwood SW11 or the Kicker Hideaway 8" powered subwoofers would fit under the back seat of a 94 Wrangler. Does anyone have experience with either of those?

JRoweMDN I managed to put an 8" sub in the console. It took a little work cutting the console and the original enclosure but it sounds great. It will not rattle everything for blocks but it sounds good inside and it left all my cargo room. I stuffed 2 300w amps way up under the dash to keep them dry.

woansleftpeg Speaker and amp are a matched pair in a single unit, which is why I didn't bother going down that route.

GotNet What gauge wire is feeding it? Both plus and minus going directly to the battery? How many watts (RMS) is the amp rated? What ohm speaker(s)?
06-12-2013 04:47 PM
wipke Is it most likely that the amp is just dead or somthing?
06-11-2013 08:43 PM
GotNet A multimeter won't show voltage sags that fast - need an oscilloscope.
06-11-2013 06:29 PM
woansleftpeg 11.9V doesn't seem to me like it would be sufficient to cause a low voltage protection mode in the amp. I'm a bit at a loss now - I can only think that something might have gone bad in the amp itself. Sorry I can't help you more.
06-11-2013 05:33 PM
wipke ok so its getting 12.4 all the way till the radio hits about 30 on the volume then the protection kicks in and goes down to about 11.9v and as the volume increases from 0 to 30 it steadily drops from 12.4v to 11.9v is there anything else i can check?
06-10-2013 10:37 PM
woansleftpeg Turn the ignition on so the amp powers up, set your MM to volts, put the black probe on the ground terminal of the amp, red terminal on the positive terminal. What power is the amp getting? It should be 12V or slightly higher. Then keep the MM on the terminals and turn the volume up until the amp cuts out, what power are you getting at the point of protect cutting in?
06-10-2013 10:28 PM
wipke Yup how would I go about checking it?
06-10-2013 10:25 PM
woansleftpeg Yes, it's possible that a circuit on the amp is bad. Do you have a multimeter?
06-10-2013 10:24 PM
wipke It's a vdp 10in system with a 750amp the ground looks to be fine and the power cable from the battery looks good could the amp be bad? Or blown. I will try to return the system again tomorrow I worked with it a little today with no luck.
06-10-2013 09:53 PM
woansleftpeg Is the amp only running the sub? I think your ground is the likeliest bet still, but also check the power cable and make sure there's no corrosion or contact with something else causing a short. Also, turn the gain on the amp right down and then build volume using the head unit only, see what effect if any that has. It might just be a case of re-tuning the amp to match the new head unit.

I'm assuming that impedance of the sub and amp isn't an issue given it was working before - what units are they?
06-10-2013 09:16 PM
wipke Yes it was working before with the old radio. And that unit got water dmged so had to buy a new head unit. It still works with at low volume still.After checking the ground what would be next on the list?
06-10-2013 08:48 PM
woansleftpeg No, you can't just bypass the protect function. It's doing it because otherwise it's going to fry, amps go into protect because something is asking for more power than is safe for them to give.

Again, did you have the amp installed at the same time as the head unit, or was it in and working before? If you want help troubleshooting, then you'll need to provide the appropriate information. The most common cause of an amp going into protect is a short in the speaker wiring, but if it's operating fine at lower volumes I'm more inclined to think that it's an issue of the ground.
06-10-2013 07:40 PM
wipke It has been working for about four days before this with the new head unit so I don't know if it would be the head unit us there any way to just by pass the amps protective
06-10-2013 06:11 PM
woansleftpeg When your amp is going into protect, it's because it's being asked for more power than is good for it. Did the amp go in at the same time as the new head unit, or was the amp in and working before with the old head unit?
06-10-2013 05:06 PM
wipke No but the tune is screw nobs on the amp right? I already did the radio but it was sounding fine until today it is a little hot out but I live in Jacksonville fl so it's always going to be. The red light says power protection. Is there any way of turning it off? So I've gone over again took every thing off and new fuse still the same thing it. The sub will run at low volume like 10 or below so real quietly but when you jack up the volume it will go to this red led normal green and says power protection red led. Any ideas?
06-10-2013 04:33 PM
woansleftpeg Did you re-tune the amp after the new head unit was installed?
06-10-2013 04:30 PM
CoreyZ The red lights on the amps typically mean overheating or power issues. Check out the user manual and it will tell you what it means.
06-10-2013 04:15 PM
wipke alright fell basically read throw this but today was driving down the high way sub working fine then nothing a red light turns on the amp and no or very little bass coming from the sub any ideas? its a VDP 10in with amp attached. i have had put a new radio in it about a week ago and has worked more then better till now. thxs fellas

desertgoose ^^^ lol. A lot of aftermarket decks come with 3 sets of RCA preouts. Some come with 2, usually front/rear with the rear switchable between full range or sub.
02-01-2012 11:12 PM
I-Want-A-Jeep ^^ I'd have to assume it's full range outputs. Most only have a sub output in addition to full range front and rear outputs.

If you head unit only has "Sub Output RCAs" then all you will get out of the is low frequencies; the head unit will block and mid & high frequencies from passing thru.

If your amps have "High Line" input on he 4-channel amp, you can tap the speaker wires from each channels and connect it to the amp. Downside.. more interference...

Another option is to get an adapter the converts your "High Line Outputs" from you head unit, into low line RCA outputs; then you can connect them to the RCA inputs of you AMP.

02-01-2012 08:08 PM
I-Want-A-Jeep You could power all 6 speakers off a 2 channel as long as you wired them correctly to obtain correct ohm load at the amp, however, I don't really recommend it.

Personally, I'm going to go with components in the ModPods and an amp on them... I'll probably throw some kind of upgraded speaker into the soundbar but that will only be ran off the rear channels of my head unit that way I can fade them out when I don't have back seat passengers. I hate having music coming from behind me..
