Yes, I just went to another professional audio shop and these guys just nit-picked the shot out of everything, basically telling me I was ripped off by several hundred dollars that I worked my **** into the dirt for. They said I was sold pieces of junk and that my best bet would be to sell my...

A little over a month ago I had installed a JL audio 10" ported box sub with a JL audio 300.1 amp. The setup was awesome in my opinion at first and then after a few weeks of great sound, it just seemed to die down to half power out of nowhere one day. I brought my vehicle back to the audio shop...

I have a Kenwood head unit, 50W 4 channel output and yes, there are sub controls in it. I have subwoofer level which I keep at +5, it goes from -15 to +15. The LPF is at 85htz. I also haven't changed any setting for the sub in the headunit or on the amp since the install, nor have I tuned...

Ok, so I have a JL audio 10" ported subwoofer with a JL audio 300.1 amp. Both were installed by a professional audio shop. The sub hit hard and sounded great for about 3 weeks and then one day it just started to sound weak, not hitting as hard and pushing bass at what feels like half of what it...

Now how exactly would I determine if my alternator has a problem? I have minimal comprehension when it comes to electricity.

Yea it's 12.7 with the jeep idling, the battery is 3 yrs old but has been holding up, I'm guessing cause it's an interstate which according to all the mechanics I know are great batts and that mine is ok, but the positive terminal always corrodes even before I had the sub and I'm just gonna...

About a month ago I got a sub and amp installed in my jeep wrangler, a JL audio ported 10" subwoofer with a 300.1 JL audio amp, the place I went to installed everything for me as well. At first, I was in love with the purchase and the sub hit nice and hard. About a week ago I was driving and I...
