I have two dual 1 ohm 18 BTLs fully loaded in a single chamber box...12 cubic feet after subs and port...with two kicker 2500.1...my gain was all the way down...my bass boost on the amps was half way up with the bass on my head unit at zero...when ever I turn my remote bass up the amps starts clipping...I had two MTX 8500 12s that hit louder on the local meter...I have a 275 amp alternator with another one on the way with two red top optimas all zero gauge wires power and ground wires...can someone help me out...I know these amps are better then this...

I agree I payed to much money to have all this break down on me over something simple to fix...for the charging system...I will have two 275 amp alternators and two D3100...wired up with 0/1 guage...is that enough ...???...or will I need more???

that is what someone also told me...they maybe my amps are not clipping...but the are actually turning off because I do not have enough power for them...I have two red top batteries...to go with the alternators I wanted get two Powermaster d3100s...I am going to set the amps at before the start cutting out...then turn on on everything in my truck to use power to see if it starts to cut off with out my touching anything on the amps...if it does I believe that it is a power problem...does that make sense to anyone else...???

CrazyKenKid I had the amp and subs installed at a local shop...they said that they set everything for me...that if I wanted more bass...all I needed to do was turn up the remote bass...but when I play certain songs with a lot of bass the subs cut off...then I looked at the amps and the amps are going into protection mode when the bass hit...so first I turned down the the bass boost down...it did nothing...then I turned the gain down all the way...they told me that they used the scope on the amps and we metered it...my RCA volts are 2.2...I do not have any line drivers... KU40 I do not know how to set the gain properly so that is why I sent it to the shop...if you have any advice on how to do it I would gladly listen...I thought I knew what I was doing...until I talked to someone who knew...then I realized I was way off so I just had everything done by the shop... also...they hooked up the second amps RCAs from the out put of the first amp...so do I set the second amp the same why I do the first one or do I just leave it lone...

Hello…my name is Dobson and I am a mechanic in the army…currently doing a tour in Iraq…with a good understanding of how to do installs…I am writing this to ensure that I have touched on every major aspect of my new install for my truck…I will try to be a descriptive as possible…so here goes nothing…I have a Chevy Avalanche…I will use the system for daily use and compete to see what it will do…my sub box will be single chamber and will take the place of my mid gate…I want to get two Fi BTL 18s…dual one ohm…subs will be wired in series to get two ohms from each sub…I will wire the subs together in parallel to equal one ohm…the amp I want is a Rockford Fosgate T40001 BD…wired to one ohm…the sub box is going to be 47 x 21 x 37 to give me 21.13 cubic feet exterior volume…interior volume using ¾ MDF will put it at 18.22…after port…subs…and bracing…the interior volume will be 14.4…the port will be 204 ¾ square inches…interior dimensions will be 10 ½ x 19 ½ x 27 ¼ …tuned to 32 hertz…bracing will go from left to right…one every ten inches…braces will have one solid rectangles cut in them two inches from the edge…I will have two pieces of wood on the back wall for bracing…extending out the dimensions to 37.75 inches…the baffle board will be tripled up…the subs will be drilled into two baffles and the third will be cut to the external dimensions of the sub and have the subs sitting flush…I will line the meeting edges with silicone and the whole interior of the box coved in resin…I have a Audiobahn 6004v amp for my highs and mids…my electrical system will consist of three alternators…one 105 amps alternator (stock) charging the two red tops under the hood which runs the truck accessories…two 275 amp alternators are used to charge up the two Kinetik HC 2400s to power the amps…all wires associated with the charging system will be Stinger 1/0 gauge and RCA cables will be Stinger as will as all battery terminals…I have the batteries under the hood grounded to my engine…frame and body…the Kinetiks will be grounded to the body and frame (if need be)…all cables will have Stinger 1/0 gauge connectors on them and will be soldered…(I hate it when one some how pops off the connector)and for the cherry on top I want to get the new Kenwood navigation unit DNX 9140 with 5 volt output…I need to drive from Alaska to New York when I get back…what I am not sure of right now is if I am going to need a external EQ…if so…I will be at a lost of how to set all the EQs and crossovers…the amps have a some type of EQ and crossover…so does the head unit…with a external EQ…if needed…???what do I set the amps and head unit EQ and crossover at…???...sorry about the long drawn out write up but if I am going to put this much money into this system I wanted to make sure that I am doing everything right…if I have left out anything…or messed up on what I am doing…please feel free to correct me so I can get on track… How do you all feel about this set up…I am a straight bass head…I want bass but SQ does matter…for the price and what I have heard…Fi is exactly what I am looking for…I like the fact that no one I know have even heard of them…just adds to the heart break when I pull up to someone and I am louder and they have never even heard of the subs I have…I know that no one can really answer this question but I have to ask…what will a set up like this hit…???...the loudest I have done is 150 with two MTX 9500 15 and the MTX amp that puts out 3750 watts…not sure what model it is… Thanks for taking the time…

WOW...I am not going to lie...I never thought that I would have to do all that to get the number that I wanted...I picked the number for this very reason...I know that it is not easy to get...but wow...I think I should try this on a car that I do not drive on a daily... if I do two T40001 amps...what size box should I make...I am not use to going this deep...I usally ask the company of the subs that I brought and they send me a box size to make and I run with it...thats about all...but I like this though...it is harder...not just throwing some stuff together and there you go...

Just checking in...just signed up today...anyone on here in Alaska???

MAN...you all are hurting my feelings...but I understand...I am not trying to cross the line of a daily driver and a SPL set up...I was thinking of dropping to a US AMPS AX3200DE amps that put out 3500 per sub...but I was wanting to sell them since I have placed the order for the Rockford Fosgate T40001 BD...what would I need to do to get to 155???...and I have heard good things from POWERMASTER batteries...are they better then Kinetiks???
