I **** at wiring!

[BAZ 10+ year member]

OK, so I ran into some problems with my installation last week. Mainly that I blew my 10" clarion sub due to me being inexperienced. I think it may have been a wiring issue. Also My amp gets really hot and shuts off. I had the gain set at practically zero and the sub made a "popping" noise right before it blew. Now the sub barely moves in the basket.

Here's what I have:

-Clarion DXZ745MP Headunit

-Phoenix Gold 6.5" xenon components

-10" kicker CVR in prefab box

-MTX RT2200X to power the sub (400 watts RMS)

-MTX RT2120 to power the components (70x2 in think?)

-Scosche (walmart) 5 guage wiring kit for multiple amps.

What the wiring kit includes:

5 guage power wire

9 guage ground wire

9 guage power wire

2 RCA's

Inline fuse

Dist. block (5 guage to dual 9 guage)

Remote wire

Is that kit insufficient for my setup? I'm not sure why you would want to run 5 guage into the dist. block and have the amps run off 9 guage. Am I wrong?

Also, people have told me that the reason my am gets so hot is that it doesnt have sufficient grounds. Is that true?

I'm looking into a new wiring kit like knuconceptz but they dont seem to have a 4 guage kit that runs multiple amps like the scosche one. I figure 4 guage running into a dist. block with dual 4 guage to the amps and 4 guage grounds would be optimal.

Please help me out, I really want to do it right this time.

You probably have the sub wired waaaaaaaaaaaaaay too low for the amp.What voice coil configuration sub do you have?

Either way, you cooked your sub.I doubt it's purely wiring.

It was a single coil 4 OHM Clarion SRW1045 and I'm not really sure what you mean when you say I had the sub wired too low. I'm still learning.

The new sub is a 4 OHM dual coil 10" Kicker CVR if that helps any.

I do not why would that single 4 ohm sub would cause the amp to shut off an blow like that, BUT I do know that your new sub (dual 4 ohm) will not work with your amp well. since it's a dual 4, you can wire it to have a final impedence of 8 or 2 ohms. You amp is not stable at 2 ohms bridged. If you had two CVRs then you can hook them up to each channel @ 2 ohms then that'll be fine.

Crap. What are my options as far as wiring that particular amp? Would this one be a better choice? Will it have enough power for the CVR? http://cgi.ebay.com/MTX-250D-CLASS-D-SUBWOOFER-AMP-350-WATTS-POWERHOUSE_W0QQitemZ9723385229QQcategoryZ64573QQssPageNameZWDVWQQrdZ1QQcmdZViewItem

Sorry for all the noob questions.

when he said wired too low he probably meant the ohms where too low for the amp to run stable

Cool, I got that part now. It looks like I need a new amp. I was looking into that MTX 250D which is 2 ohm stable. Anybody have any input on my wiring questions in the original post?

You probably need a new sub now if it won't move or makes any noises when you push it in //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

Well, I have that part taken care of. I purchased a 10" kicker CVR. Turns out I need a 2 ohm stable amp to run it. D'oh!

Looking at picking up a refurbished MTX 250D locally for pretty cheap with a warranty.

How can a single 4 ohm sub be wired for the amp to see anything but a 4 ohm load? That definetly wasn't the problem.

I was thinking he had the comp vr installed.I didn't read it good enough.

But I still have an answer for ya, you clipped the amp and still cooked it //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

Can you elaborate?

I'm still a noob. Clipping?

 

[AndonD454 10+ year member]

clipping is essentially using too much gain, resulting in a very poor, squared off signal wave coming from the amp. the amp is working too hard to provide power it cant produce, and the sub is playing a damaging wave, causing ****ed up movement..

clipping = bad for sub, bad for amp.

Cool, thanks for clarifying that. My gain was barely turned up at all. Do you think I'm running the wrong guage wire?

no that isnt the problem.

maybe the amp was toast to begin with
