Question about JBL BP150.1 Car Audio Amplifier

Open Question

Amp Smoked, Miracle?

I have my system running with a Q Power 1 Farad cap and an MTX T8302 or something to that extent. It pushes 425 watts RMS at 4 Ohms Bridged at 14.4 V. Anyway, one day while I was driving my amp had cut off, when I got to the house I checked all my power wires and grounds, I accidently took off my ground while the amp was still turned on and my amp started smoking... ALOT, when I put the ground back on it stopped smoking, and my amp still worked! Have I done any damage to my amp without me knowing? And Why did my amp cut off for no reason? (I checked to see if it was too hot and it was not)

SOURCE: I need help, amp OVER heating too much (i think)... Please help

i think your load is too low... each sub when wired in parallel can potentially be 2 ohm or 1 ohm depending on if each voice coil is 2 ohm to begin with,,,,this will cause a clipping situation as described and the over heating problem as described,,,,my email is if you have a digital camera send me some pics including speaker model numbers...I await your information so I can help you... good luck

SOURCE: JBL amp, worked fine untill 2 days ago. protection light on..

might have roasted your speakers voice coils a little which may be sending the amp into protect mode throw a speaker on it that you know works and if it doesnt trigger the protect circuit then you probably have a blown or almost sub.

I have 2 JL Audio 8W0's rated at 75 RMS. I had a MTX 280 Amp pushing them but need to replace it, what brand and size amp do you recommend for these speakers.

  • This Kicker Amp will compliment them JL Audios like nothing else. KICKER ZX Series ZX350.4 4 channels all rated @ 75 watts RMS. If it was me that would be my choice for a replacement amp.

Toxic tx 600 amplifier

You need to get another amp for your sub. I would say if you want good quality go for MTX because I have had amps from MTX and never had a problem. what you need to know is look at the fuses on the amp if there are 3 of the 25 amp fuses on there then it should push out about 750 watts but on MTX they under clock the amp so it will push about 800 at 14.4 volts for that you will need a 4 gauge wiring kit with a 60 amp fuse in the fuse link. As far as your other amp hook up the speakers and tweeters to that but be sure to tune in down and you would need a 8 gauge wiring kit. I hope this helps you.

Hey i had 2 car amps +for 4 speakers(140W maxi) and a sub 12inch

1 cap, either .5, 1 or 1.5 farad will be fine. they make 5 10 and 20 farad that cost way more than u need to spend for 400 watts RMS. i like the rockford fosgates, you can get a low cost Tsunami, just make sure you follow the charging instructions.

Will a 300 rms amp power a cerwin vega vmax 124?

Hello dustin_stewa,

300 watts RMS is a little on the low side, but it'll power the sub. The sub is rated for 500 watts RMS.

If you haven't already purchased the amp, I'd recommend considering one with a little more output, perhaps in the range of 400-600 watts RMS.

Hope this helps.

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.

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.

What is best amp to run 2 12 inch cvr's

12In Kicker CVRs
are Dual Voice Coil, and You can run each voice coil around 200 Watts RMS

So each sub will have a 400 Watt RMS and 800 Watts peak.

Now since you have 2, Your total will be 800 Watts RMS and 1600 Watts Peak.

I would get really any amp that sits at around 800-1000 Watts RMS.

These are kicker but they are low end so i wouldnt push them to the extreme.

1000-1200 Watts RMS Max and but keep the Gain down on the amp. They will hit no doubt but i wouldnt push these subs or you will be disapointed in the long run.

I would get a Fosgate or MTX amp.

You can get any amp really but find something right around 1000 Watts RMS and it will push those well.

You can go mono block or a 2 channel, just depends on how you want to wire them.

Be careful though. If your running them bridged right now with your mono block, do not run them parallel bridged on a 1000w RMS Amp, you will blow them so fast lol

(RMS = Root Mean Square. Or in other words is the continuous wattage being sent from the amplifier to the subwoffers)

Hi jimmyjames,


How do you have the wires hooked from the sony reciever to the inputs on the mtx? 

 Sounds like your Remote wire is way too big. it should be 14 guage.  It only sends a low voltage low amp signal.


Another thing that could be messing up the sounds is the routing of the wires.  you should have the power supply wires separate from the Audiop signal wiring.  Power should run down the Driver side and Audio down the passenger side.


When you answer I may be able to tell you more.
