ZX1500.1 Major Problem

I just purchased a zx1500.1 off of eBay(maybe a mistake) and just got done hooking it up. I have 2 12" L7's 2 ohm....the subs are wired exactly how they are supossed to. I hook everything up and turn on my car...the amp powers up then it seems like the subs are just getting constant power because there is just a constant sound of low bass. The subs don't hit they just stay erect and I have no idea what is wrong.

Re: ZX1500.1 Major Problem

If the subs are pushed to their limits straight out and remain there as long as the amp is on, the amplifier probably has shorted output transistors. If the speakers are moving in and out like they would be on a bass note, there may be something wrong with the shield ground of the head unit.

SOURCE: Amp cuts off...

Are the woofers single or dual voice coil?

How many ohms per coil?

If they are dual voice coil, are the coils for each speaker wired in series or parallel?

Are the speakers connected directly to the amp or are the speaker in series (one wire from each speaker connected to the amp?

Have you checked the DC voltage at the amp when you're playing it at high volume (where it cuts off)?

I have 2 10" Kicker Comp Subs

That amplifier is only rated at 150 watts at 4 ohms, or 300 watts at 2 ohms. Not a very strong amp to run 2 kicker comps. My guess is you have the subs wired wrong for your application. There are 2 types of subs, one is a dual 4 ohm, and one is a dual 2 ohm. Most people bridge these coils together and that cuts your ohms in half. For example. Lets say you have the 10cvr104 subs. Thats the dual 4 ohm sub. You wire the coils together in parallel, now its a 2 ohm sub. You have 2 of these subs running off of your amp, if they are hooked up in parallel, now you have a 1 ohm load, out of the amplifiers normal operation. Your amplifiers internals heat up really quick and there is a thermal overload, putting your amplifier into circuit protection mode. My suggestion for wiring your subs is as follows: for each speaker, wire the coils together like this- positive coil1 to negative coil 2 and negative coil 1 to positive coil 2. That is called running in series, and doubles your ohm load. Next, we need to wire the speakers together properly to hook up to your amplifier. For this, since the coils are hooked together, you only need to use one set of terminals from each sub. And take the positive from sub 1 and hook it to positive of amp. Take negative sub 1 and hook it to positive of sub 2. Take negative of sub 2 and hook it to negative of amp.

2 12" subs + 600W amp. Turn on, goes boom once, then red light

Is your gain all the way up? If it done this before, sounds like your over working the amp. Make sure your subs ohm load is capable with the amp load to. If they are 1 ohm and your amp is only 2 ohm stable, it would beat for a lil bit then go into protection mode to. Check your wires too.

I hooked my Hifonics BXi 1610 Brutus series amplifier up to my 2 12" Kicker Solo Baric L7 subs. Everything turns on on the amp but its barely pushing my subs. Ive tried tuning it and it still doesn't push...

wire the subs if thair dual 4 ohm . in parallel. red to red and black to black. giving it a 2ohm load. do the other sub the same. and conect it on the amp . turn your gain about 12oclock and db level less than 12oclock and your frequnecy around 80-100. and that should work

Hello gonenutz14,

It depends on how you define the "best way". Driving each sub with a separate 750 watt amp will result in about 50 percent more power than having them share the output from a single 1000 watt amp. But with 2 amps, there's more wiring issues to contend with and the adjustments are more complex. The 2 750 watt amps will cost more than a single 1000. Plus if the 1000 watt amp is stable to 1 ohm, the power difference will actually be less than 50 percent because of the lower impedance. But if the 750 watt amps are also stable to 1 ohm and their outputs can be combined, we're back to 2 being better than 1.

I'd say that the simplest, most economical way is to use a single amp. If maximum power to the subs is the highest priority, and cost and wiring is not an issue, then 2 is better.

Hope this helps.

Hello smoot_dog,

Well, you did not specify whether you have the 2 ohm or the 4 ohm versions of the L7 and that will impact your choice of amps. But with 8 voice coils and 4 subs to work with, you certainly have lots or potential configurations.

If your subs are the 4-ohm version, I would recommend the Alpine MRP-M1000. Currently it is on sale at for $347.00. With this amp you'd wire the voice coils in parallel (2 ohms), wire each of the 2 pair of subs in series (4 ohms), and the resulting pairs parallel to the amp for a final load of 2 ohms.

If your subs are the 2-ohm version, I would recommend the Rockford-Fosgate Punch P1000-1bd which is stable at 1 ohm. Crutchfield sells it for $349.99. With the Punch and 2-ohm voice coils, you'd series the voice coils (4 ohms), parallel each pair of subs (2 ohms), and then parallel the resulting pairs to the amp for a final load of 1 ohm.

Either of these amps will provide an honest 250 watts RMS to each L7. They'll not only rock your vehicle, they'll rock the pavement.

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

Hooking up DVC subs

The amp is rated to run a 2 ohm load on each channel. To do this, connect the voice coils of one sub in parallel (tie both "+" on the sub to each other and both "-" on the sub to each other), then connect that sub to one channel of the amp. Repeat this process for the other sub and connect it to the other channel on the amp. The subs will be in stereo and the amp will be outputting it's maximum power.

Amp overheating and adjusting gain and frequency

Overheating in amplifiers is often caused by a speaker load of too low impedance. If your L7 is a dual 4-ohm voice coil, and if you're using the amplifier in bridged mode, that may be causing your problem. Dual 4-ohm subs, with the voice coils wired in parallel, present a 2-ohm load to the amp. Your amp is capable of running a 2 ohm load in 2-channel mode, but not bridged mode. The best fix with your equipment would be to re-wire the sub's voice coils in series, resulting in an 8-ohm load. The amplifier's power output will drop sharply, but you won't have problems with overheating in that configuration. There's a good chance that you'll still be able to get all the volume you want, even with an 8-ohm setup; otherwise you'll probably want to switch to a mono amp designed for a 2-ohm load.
