Question about Kicker Comp 12" Car Speaker

1 Answer

I have 2 12 kicker comps (less than a year old) wired to a 4 channel alpine amp but bridged into a 2-channel at 130 watts per channel. The subs went intermittent for a while and now are just really quiet. The amp is probably over 10 years old. Any suggestions?

My guess? A such an old amp had equally old capacitors. These old capacitors weren't unable to resist to the higher current generated by running the subs in bridged mode so they failed. When they began to fail the final mosfets failed first - what you are hear now is probable the output of the prefinal transistors - barely audible.
Time for a new amp - check the subs first, they might have been damaged themselves.

What is the best way to wire two kicker comp r 12' s to a two channel amp for max bass?


First, you need to know whether you have the 2 ohm DVC subs or 4 ohm DVC subs. Second, you need to know the minimum impedance the amp can handle (most are 2 ohm, some are less). Putting two voice coils in parallel will cut the total impedance in half (e.g. 2x 4 ohm voice coils in parallel = 2 ohms total). Putting subs in parallel will also cut the impedance in half.
At one end of the spectrum, you could put the 2 ohms DVCs in parallel, then parallel the two subs, and bridge the 2 channels of the amp. That would put 0.5 ohms impedance on the 1 bridge amp channel. If the amp can do 0.5 ohms x 1ch, do it. Otherwise, you may have to run the subs on separate channels.

I have 2 12


To be on the safe side without further information I would hook the two subs up in series leaving you with an 8 ohm load.

What size amp do i need to run 4 1000 watt pyle 10's bridged


well first of all you cant bridge subs... you can bridge an amp... and for 2 they are probablly not 1000 watts, make sure you understand RMS and what the sub can ACTUALLY HANDLE properly... i would get a 1000 to 1500 watt RMS that is RMS RMS RMS RMS amp not one that says 2000 watts MAX POWER cuz thats cheap ****... get a kicker JL hifonic alpine or something in that category that actually tells you the TRUE power output of the amp... then run those 4 subs in a parallel circuit so its like really only having 2 subs. make sure then these subs do not run less then 2 ohms at the terminals while in a parallel, then bridge these subs acting as 2 subs not 4 to your TRUE 1000 watt amp and you should have a good powerful system

Will this amp power two 12" subs?


Yes. The Kicker xs50 competition amp will l ! Pushs my old school autobahn aw1206t's very nicely and beats my 2 sundown sa15's senseless. Wire down to 1 ohm and bridge. People may say yeah rite. Ok. Thats ok.

Hi i have two 10'' jenson xs sub and they are about 6 years old and i was wondering wut amp size i should buy to run them.


I believe these are 4ohms, if so buy a 2ohm stable monoblock amp, that puts out 250-300 watts RMS, and connect your subs to it in parallel, don't pay attention to peak watts, look at RMS watts, or continuous watts. If they're 2 ohms, buy a 2 ohm stable 2 channel amp that puts out 125-150 watts RMS per channel, and 250-300 watts total or bridged RMS output. And connect them normally, on sub per channel... hope this helps, as far as brand recommendations, MTX, pioneer, Alpine, Kenwood... Good luck

Got a 12"kicker L74ohm sub and sony xm-D9001GTR mono amp


Hello juan_penaloz,

The Kicker L7 has an RMS power range of from 50-750 watts and a maximum power handling capability of 1,500 watts so your Sony amp will power it OK. A more powerful monoblock like the Alpine MRP-M1000 or the Kicker 08ZX750.1 would provide even more power and could operate safely at 2ohms.

You have the voice coils wired properly for the Sony amp. It's OK to have the sub impedance higher, but you definitely do not want it lower than the 4ohms the amp is rated at in bridged mode.

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 have a kicker zx700.5 amp


Hello aj_vidal22,

Here's the link to MTX's sub page where you can view or download the information you need to properly wire the subs to your amp.

http://www.mtx.com/caraudio/products/manualsQuickInstall/subs.cfm

For maximum power, you'll need to wire the subs so that they present a 2 ohm load to the sub outputs on your amp. That will give you the full 420 watts RMS the amp is rated for. Likewise, you,ll want the run the front 4-channels at 2 ohms. Run separately, they produce 85 Watts times 4 channels, or if bridged, 130 watts times 2-channels. But if you run fronts at 4 ohms, they only produce 70 watts times 4 channels and your sub output at 4 ohms drops to 210 watts.

Hope this helps.

2006 12" Kicker L7 4 ohm


first whats the range in terms of WATTS that your 12" sub can handle in 4 OHMS ? second , lets check the AMP , POWER ACOUSTIK 1800 WATTS , Now thats a lot of power to drive a single 12" sub speaker . your amp is 1800 watts , per channel is around 500 watts , if BRIDGE thats around 1600 watts rms for ONE channel , if your sub can handle that kind of wattage fine , but it will not blow the amp , what it does is shuts down , some kind of protection mode , it will come back on after a minute or so. I suggest to use one channel in stereo mode , or purchase another sub to use the other channel. i hope this helps AJ

Bridging to 12 inch kicker competition subs to my 1000 watt alpine 4 channel amp


I'm a bit confused. For Alpine amps, the "M" prefix is for monoblock (aka single channel) amps and the "F" prefix is for multichannel amps. The only M550 I find is an MRD-M550, which is a monoblock, not a 4 channel like you say.
Unfortunately, I can't give you accurate help until we know weather it's truly 1 channel or 4 channel. Then I'll be glad to help!
