Sub Suggestions

I recently purchased and installed two 10" JBL subs in two separate downfiring truck boxes in my Ext. Cab Silverado. I have a Rockford Fosgate P3001 amp powering them. I got the subs and boxes for really cheap and they kind of suck. I was wondering what would be some good replacement subs. I'm not really looking to spend much more than $100-$150 for them and the cheaper the better. I just want something that produces good quality bass and won't distort at moderately high volumes. Any suggestions would be greatly appreciated.

Some more info would be appreciated. What size is your box? Is it under the seat downfiring?

 

Also, it may not be your subs that are sounding like crap, that is a really low power amp, and at higher volumes will start to distort. For a decent sound, expect to spend around $100 for each sub and about $300 for a quality amp.

 

As far as brands, i would look into Alpine, JL, and Kicker.

They are two small sealed truck boxes that are under the back seat. One on the drivers side, one on the passenger side. The amp is mounted in the middle. I'm pretty sure it is the subs that suck. I don't know what the RMS wattage is, but the peak power is only 200W. My friend has the same amp in the same truck and his sounds a hell of a lot better than mine does. Those kickers seem like about what I'm looking for. I might have to get a couple of those.

You can't compare amps in 2 vehicles, even if they have the same components. The box, and acoustics of the vehicle play a huge role.

 

And 200w max...wow...i have 200 going to each of my door speakers...just as a comparison.

 

200 Max...which would be 100 RMS...which would be 50 watts per sub. Just keep in mind that most aftermarket head units will put 50+ watts to your reference door and dash speakers.

 

It could be mismatched subs to their enclosure, while your friend has better matched volumes. It could also be his subs are better matched to the amp.

 

Also your deck plays a huge factor. You could have thousands invested in speakers and amps, but if your HU sucks, the sound will suck.

Ok, I have another question. For some reason, earlier tonight my subs were hitting great. They were producing more and clearer bass with the volume lower than the usual setting I play my stereo at. It did this for a while. I went to a couple of places over the course of the night, turned off my truck came back and they still sounded great. Later, after I had been at a friends house for a while, I got in my truck to go back home and they sounded about like they did originally, which isn't very good even an moderate volume. What could be the cause of this problem? I was thinking maybe a ground problem. I haven't had anytime to mess with it so I don't know. Could this be a possible reason for this?

Describe the sound. If it is highly distorted at even low levels, you could be shorting out, or have a ground loop. Also need to check to make sure your connections are secure and haven't vibrated loose or anything like that.

Were your windows rolled down when they sounded better?

      2027 GMC Sierra: Official Discussion

      By Jsdirt · Posted

      I was around and remember that era very well, so I'm calling b/s on that statement. If they were that bad no police department or taxi company would've bought a single one ... but they were used in both services (and fire) for DECADES. They were bulletproof and proven. Even the early 21st century ones weren't too bad! The early models were legendary.   Mine is proof, but people like atlas are blinded by agenda and refuse to believe facts right before their very eyes.   Even decades after they were built, a new generation started driving them, posting all their builds and shenanigans on Grandmarq.net and Crownvic.net. The failures would show up then, since they all were deep past 100k-150k miles by that point, and younger drivers tend to be a little aggressive, especially with vehicles than can lay a one-tire fire for as long as you hold your foot in it. They've more than proven themselves over the decades.   The only thing that'll really take them out is road salt. The bodies and sheet metal were garbage. A victim of the cheapout FoMoCo and GM have been partaking in before then, and since.   Today it's the stuff that counts - the undercarriage that rots away first!    GMs Caprice was no slouch either. Reliable as a stone ax - the opposite of what they build now.

      Let me know how your vehicles do in 10 years. You don't know ******, kid. 😂    There's a reason that Panther platform was used as police, fire, and taxi service for DECADES ... long before you were born, apparently.

      Disconnecting Battery

      By davester · Posted

      If your connector also has a big lever to get the connector on and off, you don't want to force the lever either way, as it becomes a bigger problem if you bust the lever or the mechanism it works.

      Disconnecting Battery

      By davester · Posted

      It's just useful to disconnect the battery to prevent odd shorting out when unplugging/plugging stuff together.  I also  touch the two cable ends together (after disonnecting) to drain the small amount of stored battery energy in various modules.   I believe the main system where you need to be more concerned with, so you need to do the above and then wait some time, iss when you are working on the air bag system, to prevent inadvertent firing of the air bags.   The in-cab switches are just that, plain switches, it's generally not a problem to swap them in/out.  For my '12, I'll get an error message on the dash if I power up the truck w them unplugged, but that's it (power up= turn the ignition on).   The ITBC located above the spare tire is a computer that manages the trailer brake system.  That is probably more important to have the battery disconnected.  It does have to be programmed to the truck, either before or after it's installed, for it to work.  For my '12, I had a very hard time reinstalling the main connector to it (IDK if yours is the same or not), it turned out the silicon seal was jamming up, preventing it from going on all the way.  I finally got it fully installed by lubing the seal with a bit of dielectric grease, then it slid on and latched in place easily.

      Remote Start Noise 2024 2500 HD Gas

      By BCGM · Posted

      JR ! I just got the truck back from the Dealership today . The technician did a cold remote start on the truck this morning and it made the noise . It was determined that it was a starter issue and replaced it under warranty . Of course   it did not make the sound after a new starter was put in because the truck was not cold . We will we see what happens tomorrow morning when I start the truck cold  . Keep tuned !   Oh I found a video on YouTube of a cold start and it did the same thing your truck and mine do , I will see if I can find it and post it up
