    New system doesn't sound right

    Going to need to narrow it down a bit, friend. This really isn't much to go on.
  2. Yep. This is why I always question newbies who think they need to tune into the low 30s. Also, good looking box, OP. I've never had good results with multiple round ports myself but for what that sub is I don't suppose you're chasing 10ths on the meter.

    PRV amps

    Why? Are they getting more expensive? No such thing as a free lunch.

    Tapped Horn "expert" wanted

    diyaudio.com will be a better source for horn projects. I have yet to see a true horn build on this board.

    PRV amps

    Implying Brazilian amps ever had decent QC or reliability. You're buying at 5 cents a watt for a reason.
  6. Different wood isn't going to fix that, what you need to do is figure out a way to firmly secure the box to the floor of the vehicle if you want it to stay put. That box looked sound enough with the bracing and all. If panels are flexing add more bracing or double wall that side, if it's just the box itself moving work on bolting it down somehow. IF you do redesign figure out how to leave yourself room to mount the amp not on the box.

    And 30 years of seeing how these garbage brands operate tells me that they'll slap their name on anything and if someone hasn't tested the exact model in question you should expect he worst. I can think of a few brands that had one or two decent amps ever while everything else in their lineup has been pure trash. This is why I hate to support that sort of company.
  8. For the record, the frequency response will more model like a larger box for you but you will not gain efficiency you would if you actually had that airspace. Bear in mind your cabin gain may give you enough low extension where you don't need the curve you think you need to sound "good" and sealed boxes are quite forgiving anyway. A 30% change in volume doesn't really even change the response graph much. Easiest check is model the sub in WinISD to compare what you could even expect, or just buy 10$ worth of batting and test for yourself.

    Ignite 2000 watt max

    The point being does the """2000W""" model even do half of the one Derek reviewed? Will it blow up out of the box?

    Again, there is no "good" way to mount an amp to a box period. If you had that much room between the box and the rear of the trunk you should have built up an L shaped board mounted to the floor floating free from the box. If you believe the sides aren't flexing but the box is vibrating you may consider bolting/securing the box to the car somehow. Then you just get to the point where every bit of the car is vibrating and you're still getting undue wear.

    OP suggests that the review was of the double-size unit from that "brand"

    If nobody has tested it nobody has tested it. With these flea market brands and low priced electronics the "half size" model isn't necessarily just the big board scaled down. These companies buy whatever boards they can get the cheapest from China and have their name slapped on them. The point being when you're buying out of the bargain bin you need to be very careful you get the precise make model and year/series as in the review if you want to expect the same performance of the reviewer. Lastly if someone dyno'd this and it made power without blowing up it still may or may not be a reliable amp. Most of the cheap amps are hit or miss at best with build quality, quality control, and reliability.

    Again, there really is no "good" way to mount an amp to a box. Whatever you do just keep in mind it will lead to premature failure when compared with mounting elsewhere. For a test put it all together, get it playing full tilt, then put your forehead on the amp and you will be able to notice how much it is actually vibrating.

    Do what you like and you may or may not get away with it for some period of time but mounting amp(s) to your box in any way shape or form is sketchy.

    Do not mount amps to your box period. There is no good way to do it. Build an L shaped frame mount to the floor so that the amp(s) float away from the box if that's your only spot.
