Green light blinks slowly on my JL Audio 300/4 amp

I just replaced the battery in my 2004 Avalanche and the receiver and subwoofer (bazooka) works, but the JL Audio 300/4 power amp is not working as the green light slowly blinks off and on. Help!

    We found the problem to be the ground wire attached near the driver's side rear door. After reattaching with a new washer, everything worked. Thanks.

    I have a Hollywood Amplifier 750w...and this green light keeps blinking on/off...i tested on my friend's car to check if it was a wrong connection on my car, but the same thing happened. Some one on the web told me it could be the solders inside the amp. is it true?

Check your fuse at the battery. While AGU glass fuses "look" good, when you read the voltage AFTER the fuse, you can only be getting 5 volts or so. I can't tell you how many times I have seen this.

If this woofer is a dual voice coil woofer and if you are running your amp bridged or in mono would suggest try wiring your woofer in series.But before Idid anything I would unhook the woofer from the amp and pop it with a battery to make sure your woofer is still connected.

Can you use a bazooka ba1150 to power up an infinity 1230w sub? not a techie just happened to have these two items and was wondering if i can use them together. thanks.


This is an 150 RMS amp, but the ratings say it'll push 2 10's.
You probably won't get much out of that amp with a 1230 watt subwoofer.
The subwoofer you are wanting to run is 300 RMS, so you'll get half the power you could be pulling. But it would do okay I guess. Nothing like what you could get with a different amp though. You need like a 1000 watt amp to get the most out of your sub. But "YES" you can use them together.

JL audio w7 is not working but not blown


Possibly the voltage spike/surge destroyed your subs. I am surprised you didn't lose your amp as well.

I NEED A SUBWOOFER THATWILL FIT INT A 2008 MISUBISHI RAIDER CLUB CAB( SAME AS DAKOTA. ANY SUGGESTIONS


Hello andrewsa104,

If you are looking for something that is made specifically for vehicle, two possibilities are JL Audio Stealthboxes and MTX Thunderforms. These are generally "turn-key" systems with amps included. But check.

Here's a link to a thunderform that fits a 2002 - up Dodge Dakota Quad Cab.

A less expensive approach would be a generic powered subwoofer system that you fit under a seat or behind a seat. Many manufacturers offer such solutions, including Bazooka, MTX (thunderlink), Infinity (basslink), etc.

Hope this helps.

Got jl300/2 amp confused which subwoofer sounds good


Hello drsubhakar26,

JL W6's will perform well with from 150-600 watts RMS. W7's with from 150-500 watts. Less expensive Alpine Type R's work OK with from 200-500 watts RMS. Either of the brands will sound good. None of them will perform to their full potential with 300 watts RMS. Powering any sub with a 2-channel amp is a compromise. A monoblock is more efficient.

Hope this helps.

Wrong connection continuation


If you're installing this in a vehicle with a 12 volt charging system (most automobiles are 12v), I think the batteries may be dead in your multimeter. You shouldn't read anything over ~15v.

When you measure this again, place the black lead on the ground terminal of the amp.

Wrong connection


You should have blown a fuse. Check the main power fuse feeding the system (usually at the battery). If it appears to be good, you'll need a multimeter to check the voltage at the B+ and remote terminals of the amplifiers. Place the black meter lead on the ground terminal of the amp when testing. .
