  2. 4 Gauge vs 8 Gauge sound quality ???

    General Car Audio Discussion
    Currently I am running 8 Gauge power wire with the JL HD750 amp and 12W7 subwoofer. Distant is about 7-8ft from battery to amp. Everything work fine and sound great. I wonder if I upgrade to 4 Gauge power wire, will the subwoofer sound ever better or there wouldn't be any sound different?
  3. how you'd start planning a 2 sub wall?

    DIYMA - SPL Forum
    Anybody with experience with dual 15 or 18 sub wall set-ups? I've got over 14 cu. ft., maybe 16 or 17 with some wierd angles. I've been told to keep it as squared off as possible in side, but it's a two-door neon so I could go into some cavities and up over the rear deck for some more space if...

  7. Does SQ matter when listening to music really far away

    Technical & Advanced Car Audio Discussion
    One example I have in my mind is lets say you have a great system everything is down perfectly then in a car here you roll your windows down and people hear your music. Would ppl notice the difference btw a stock system tuned correctly vs a sq system tuned correctly? Would people actually be...

  14. Low shelf filter or cabin gain filter for a car?

    General Car Audio Discussion
    Hi all, I tried to search on google already, but, you know my search skillz are for poop, so forgive the question. If my tests tomorrow still show a huge 12db drop after 50Hz, it seems it would make sense to look for a low-shelf filter to cut frequencies starting at around 55Hz and lower...

    Okay, I've notice that few if any drivers that you can buy are actually stress tested to certain decibels of SPL for audible distortion/motor noise. So, I wanted to think up a way to manually stress test drivers as safe as possible but with some risk in a cost-no-option method. Certain...

  18. Help designing enclosures for rear deck 6x9's.

    General Car Audio Discussion
    Hey, I need help designing a custom 6x9 enclosure for each separate 6x9 in my car's rear deck. The problem: My 6x9's are currently housed in baffles in the rear deck that cup the speaker (protecting it from the violent bass air from the sub), giving it no space to push air of it's own and thus...
