Some background: I have always liked the F150 trucks and have owned several of them over the years. I had been planning out a system for those trucks for years and picking up the odd component here and there (most notably the Mechman 320a alternator and the XS Power D6500 XS AGM battery. I had planned on doing a system in a Supercrew 4-door and had also picked up a DM810 thinking I would integrate it into the factory (non-Sony) system. Some time in 2019 I decided I was sick and tired of having payments with wheels and made a few decisions that included trading my 2018 Lariat Supercrew in for a well maintained 2016 Supercab (the one with the funny half suicide doors). I had enough equity in the 2018 truck that I barely had to come out of pocket on the 2016 truck at all and I then had a solid work truck with no payment. Now I've got a solid work truck that I plan to drive until the wheels fall off. I also have a daily driver sedan that most of my mileage goes on and I only use the truck for towing, material pick ups, dirty job stuff - you know - work truck stuff, so I'm hopeful that it has years of life left.

All the fab work was done with normal power tools with the exception of one box trim piece that I used a 3D printer to make. No CNC or Laser work. I'll stop here and respond to the post with the build log pictures as I don't know if the site will time out if I spend an hour writing up a post

Greetings, I have 2 Kenwood 12" 4ohm DVC performance series woofers (KFC-W12DVC) rated for 250watts/1000max. I can wire them for either 4ohm or 1ohm. I'm shopping for a good amp to power the pair and my question is; should I be looking for an amp to push 500 watts at 4ohm or 1ohm? Does it make a difference as long as it delivers 500w RMS at the correct impedance for how I wire the drivers? Also where the max power for the woofers is 1000, does that stay there, or can I get an amp that will push 1500 to 2000 max? Someone also mentioned getting a 2 channel amp and running it with each woofer at 2ohms but I don't know about that because aren't 2 channel amplifiers full frequency? I'm looking for Class D monoblock subwoofer amps because that's all it will be for and they stick within subwoofer frequency range. Any input is greatly helpful and appreciated. Just in case anyone is wondering, because I have been asked a couple of times, the reason I have 2 dual voice coil 4ohm subwoofers is because I didn't know the difference when I bought the first one, I just thought 2 voice coils would be better than one and that 4ohms was very stable. That driver is awesome, it's taken all the poundings I have thrown at it for well over 2 years. I listen to a wide variety of bass heavy music genres from speed metal to downtempo coffee house trance and anything and everything between. If it's got bass, bpm, and soul, it's on. The little 250.1 DX series Kicker has overheated a few times trying to push it so I'm in the process of a budget conscious upgrade and I wanted a second driver to match my current hammer for cost savings and because of the performance I've seen from it. I've had it in a sealed enclosure that housed a 12" Kenwood SVC originally, but the little Kicker ended that one's life almost immediately. I did buy it used and I think it was a sub par woofer because upon inspection, the speaker just looked cheaply made. Small magnet, small diameter motor/voice coil and a paper cone, but it did say Kenwood on it. The amp I bought new but it's having a hard time with the one I have so I am amp shopping and have become slightly overwhelmed and that's why I'm turning to experts for help. I have a dual enclosure that a buddy gave me for nothing but it's ported and the chambers are way too big for what my drivers call for so I'm going to modify it and am going to be eliminating the ports. I like the performance I have seen with the sealed box that I have now and I don't think I'm interested in changing to a ported box. I've done some homework on box construction and I'm pretty confident that I'll be ok there, I'm only throwing that into the mix because if I understand correctly, it does have an affect on amplifier/driver performance and needs/recommendations.

Ok probably a dumb question but ima ask neway i set my gains on the hu, fr amp, and sub amp with the disc as im supposed to and all is good. and for shits and giggles i played music and tested my amps with the dd1 and get a solid distort light light on my full range amp and a flashing on the subwoofer amp. Is this normal??? everything sounds fine just dont want too damage my equipment... Question 2, I have a Kenwood kdc-hd548u and it has a sub level -15-+15 adj as of now I have it set at 0 but after researching some say crank it up then set gains and some say keep it flat then set gains. so idk wich is better level high gain low or level flat and gain high????THANKZ

my system was loud as shit but after a having it for a couple of weeks it just isnt the same but is still loud.. so i gotta ask is it just me or is something wrong? could i be just getting used to it. it happens everytime i upgrade.

This is what happens when you try to record loud music with a phone. The entire system is being run off of a hifonics 5 channel amp. The sub is an XFL 12 and its stiff as a board! 136 db's on music isn't bad for a single 12 not broke in off of a 5 channel tuned to 36 hz. http://www.facebook....&type=2 http://www.facebook.com/#!/photo.php?v=3405925583584&set=vb.1133222970&type=2&theater
