      @Eric Prough The signal from your source unit could be at a voltage higher than the amp. The pop is surge current. You need to match the gain so they are the same. DSP is a filter to stop added THD Total Harmonic Distortion. It should not be a problem for subs though if you have full range speakers more THD is added with more circuits. Look it up on youtube and online.

      @ROBERT FRIEND what does dsp mean and what do you mean line level. What caused the problem all i did was switch my amp kept everything else the same.

      @Eric Prough Your line level is not matched, the output from music source to amp needs line level with dsp output to match the gain. The best thing you can do for now is turn down the volume and gain before switching on or off, you can put a switch between Battery and Amp and switch off amp before switching off the source and amp too. That is how I solve the problem. Get high current anti surge rocker switch or LOC with DSP.
      DSP is a filter not all LOC have it.

      I made the phase mistake. I had everything installed right and in my last car it sounded fantastic and hit the back of my seat real nice. But in my new car it seemed like all the bass was just soft and not powerful. I had it forward firing into the rear seats. However when I opened my trunk up it immediately started pounding like it used to. Not sure why. I decided to turn my box around so that it can fire backwards towards the taillights and that solved my lack of bass. Super simple. Made me really happy with my install.

      You can use a simple 9v battery to determine the polarity. With the positive connected to the positive and negative to negative the cone will push out. Reverse it will pull in. Only hold for a moment, no heat will build, speakrs don't like 0hz.

      you also can test a speaker polarity with a 1.5 battery, positive concoction of spear and positive concoction from battery than the speaker will push forward

      Thank you for putting this out there! I still cant figure out how to duplicate the system I had in my 1998 extended cab s10. I had 2 jl 10s in separate sealed enclosures behind the seats with the stock head unit and ac delco speakers which I believe at that time were produced by Bose with a pyramid 150 amp. It was perfect! Especially for rock and metal and still hit hard! I now have a quad cab 2005 dodge ram with a kenwood deck and alpine door speakers. Can you help me recreate that sound I miss? I also have an SAS 8 inch that came with a 100 watt amp. It would mean the world to me if anyone could help me recreate that sound!

      Is it okay to have your subwoofer flush against the back of your seat or under your seat I have a 2001 Dodge Ram and it does not have a lot of room it's a extended cab so I just have to 10s in the floor behind each seat and then a really big 12 just sitting on top of the back seat but if I could flip the boxes up or slide them under the back seat then I would have more room but I figured it would mess the speaker up if it didn't have room to move I thought I knew so much about car audio until I started putting a system in my truck you actually have to be very good at math to get the best results lol and I suck at math

      Great Video. I have a question. What is the best way to fit a 12" subwoofer in a 1993 Jeep Wrangler. I already have it installed but just in a loose box, the system is very loud but I'd like to be able the get the sub box out of the way, or build a custom box for it. I know not much room to work with. any idea's?

      @Junior Awesome, I knew about the box for the 10's but didn't know they had them for 12's. Thanks for the information, I appreciate it.

      One more thing, go buy pillow stuffing, and fill the sub box with it, it can help you get bigger sound from a smaller box. Dont over stuff it, but dont be afraid to pack it in a bit. Should be slightly firm to push in.

      I have a 98 wrangler with 2 10's in the rear. Ebay has down firing boxes that fit in the back and allow you to keep the rear seat. Thay also have ones for 12's. Check it out!

      Also buy a solid car to install an audio system in. Too many ricers with huge subwoofers in a old japaneese clunker which rattles to death by a single 12" sub at 300w. I have built in a few cars and i prefer Mercedes or BMW since they are rock solid!

      I'll take my "ricer" car any day of week over those money pit German cars. Yes, the German cars are fun to drive and handle great, but when they get near 100k miles, they turn into money pits when everything starts breaking down.

      hi mark I wonder what it's a proper way to install two subwoofers, in a car. and what's better way it's to get two amps with one channel like monoblock for each sub. or better like install one amplifier with two channel
