Watch the bass I understand what you are saying now and you're probably right about the box not being exact. I looked into the bandpass enclosures when I decided to build another box but decided that it was in no way feasible with the area that I have to work with because I would like to have the passenger seat go all the way back (it does right now) and have the drivers seat go partway back a little past where it was comfortable for when somebody else drives it. Looks like I will be designing a new box and I will have to try the aeroports this time they look like they will make it a lot easier. Can you give me any recommendations about the box size and what you guys think the tuning frequency should be at? I will consider doing a new amp though to because that seems like it is more needed then a sub, when I bought it I was looking for the best bang for your buck on a cheap budget. Also has anybody had any experience with Directed amps? I am looking at a used one for $230 its a Directed 1100D.

I have already done all the ground wires and the alternator power wire, it is the stock alternator but it is brand new because my old one got replaced right before I did the system (didn't think about putting a system in at that time) and when I watch the voltage it barely ever goes below 13 volts, and I can leave it playing for hours and the truck still starts fine. Also when I said that I cant get enough volume I mean that even with the gain adjusted all the way up when I turn the head unit volume up it doesn't seem to distort (I thought this may be because my ipod does not have a high enough voltage or something), I don't turn the head unit quite all the way up though because I have the rear speakers running off of it with no amp and they distort. All of the bass boosters are off from the head unit and the amp I don't understand what I can tune differently about it I thought the gain was to adjust that amp according to the rest of the speakers playing. I have considered building a new box but its extremely difficult to build a ported box to fit behind the regular cab seat and I felt that I did the best I could do for awhile, I built a sealed box the first time and wanted more so I built the ported one I have now. If you guys think that will make a big enough difference then I might have to try that but I wasn't sure what my weakest link was through the system. Watch the bass are you saying I should build another box because mine is throwing the sub out of spec? Sorry I did not really understand your post. And I do like the sub it does very well with rap and that kindof music I just have been listening to other kinds lately and want to find out how to get better SQ. Oh and Mha the hifonics speakers have really surprised me being that they are so cheap. An amp is a must and they have very little bass but if you have a HPF then they seem really clean when they get loud. Again sorry for the long post but you guys are great 13 replies in one day lol thanks everybody!

Hey all I have some questions about my sound system and I'm not sure what to put this topic under so feel free to move it for me. But I am looking to upgrade my sound system from what I have now but am not sure where to start. I have a regular cab F150 with a single 12" CVX behind the seat in a custom ported box. It is being run from a Hifonics HFI1000D amplifier at 1 ohm and gets pretty loud. For the mids and highs I have a pair of Hifonics 5.25" components running off of a Rockford Fosgate P300.2. The mids and highs sound good to me and I don't have a problem with them partly because I got an amazing deal on them. But lately I have been listening to all different kids of music and the bass SQ leaves some to be desired. Also when running it hard it seems to be extremely loud for the first song or two but then quiets down and I can't seem to get the volume out of it playing from my ipod for the sub amp even with the gain all the way up. I would guess this is because the amp is getting warm but I'm not exactly sure. This is the first system that I have had and I do all of the installation myself but I would like some feedback on what to upgrade. I want better SQ and would like to keep at least the same SPL or a little more. I can't spend more then like $300-400 dollars on it right now. Sorry for the long post just tryin not to leave anything out. Thanks everybody, Josh
