abaddon Posted April 12, 2010 Report Share Posted April 12, 2010 Here's the deal.. I bought 2 12" Kicker CVXs with a box from my buddy. Subs were tested and bump hard. I also bought just a temporary Fusion 2000watt mono amp until I can buy my Hifonics Brutus. I am running 0awg for Power/Ground and for some reason... This doesn't bump AT ALL!!! The subs move, but move sloppy.. No air is really coming out of the port and the sound quality is just shit. Hardly hits any notes at all. Sometimes when you turn it up it seems like the subs turn themselves down, but the amp never goes into protect mode. I was thinking it was the amp, but I'm not sold because it just came out of my friend's system running 2 12" Type-Rs and this amp rocked those subs! The whole reason I even bought the amp was because I have seen it bump subs! I ran out of ring terminals so my ground is bare wire connected to a seat bolt in the back of my Expedition, so I was thinking it might have a bad ground. I also thought it might have been the used RCA's I got with this wiring. They are nicer gold-plated RCA's, but wasn't sure. Any ideas at all? Took a multimeter to everything, RCA's tested fine, ground was re done but still no terminal(until tomorrow when shops are open) so I'm stumped. I'm guessing it's the crappy amp but like I said, it was just temporary. Buddy won't buy it back from me now.

ktm300 Posted April 12, 2010 Report Share Posted April 12, 2010 They wired right? Are they in phase? Quote Link to comment Share on other sites More sharing options...
baaudio Posted April 12, 2010 Report Share Posted April 12, 2010 (edited) That's weird man. At least you KNOW the stuff works. I would say double check all your amp settings and hu settings. The hu outputs might be the problem. If your running a hi/lo maybe check the outputs and peg them if you can.

abaddon Posted April 12, 2010 Author Report Share Posted April 12, 2010 (edited) Subs are wired perfect to 2 ohms in the box. I know the kid who had the amp before me had his subs at 1 ohm, but come on my subs should STILL be bumping harder. That's weird man. At least you KNOW the stuff works. I would say double check all your amp settings and hu settings. The hu outputs might be the problem. If your running a hi/lo maybe check the outputs and peg them if you can. It's very strange. and what do you mean by Hi/Lo outputs? My Head unit is a JVC KD-S100. I have seperate RCA Subwoofer outputs and more different RCA inputs for A/V shit. Oh, and tomorrow, I'm adding a second battery with a Stinger isolator.

Are you sure you have the positive wire from the subs running to the positive terminal in the amp and the negative to negative, or if there's a phase switch its not on 180. This sounds like the problem. Edited April 12, 2010 by vengfuldev Quote Start out boxy, shape as you move along. Dc Audio Team Fur Link to comment Share on other sites More sharing options...
dyeagain15 Posted April 12, 2010 Report Share Posted April 12, 2010 i have the same headunit ^^^ yea i'd say its the ground cause im running a kicker cvt (just for now) of a rf 500.2 with a body ground, no trouble at all. sound comes out nice and clear Quote My F-150 Build (So Far) 2 DC L3 10's Kenwood KDC-X794 (4) Selenium ST200 (Highs) (2) RE X8 (Mids) Sundown Sub/Mid/High Amps Shuriken Batteries Knu Wiring My Feedback Thread Link to comment Share on other sites More sharing options...
baaudio Posted April 12, 2010 Report Share Posted April 12, 2010 A hi/lo is an adapter you put in to convert speaker wires into rca outputs. This is only on stock hu that they do this. But ya I agree^^^ ground is the problem Quote Team NWSPL baaudio Build Log 2001 GMC Sierra walkthrough 4 Mechman Elite 370s, 10 AGM batteries, 3 Crossfire XS v2 18s, Crossfire 8k Link to comment Share on other sites More sharing options...
finkster Posted April 12, 2010 Report Share Posted April 12, 2010 seat belt bolts suck...lol wait until u get a real ground with a ring terminal and re check. also make sure your filters on the amp are set right. 80 for lpf usually... check fuses and wiring. did u try adjusting the bass volume from the head unit?

chewie Posted April 12, 2010 Report Share Posted April 12, 2010 ive barebacked wire for ground before.. so thats not the problem.. unless its a bad ground spot.. i would check your head unit.. take your volt meter and put it on dc volts and play a song with the woofers not attached.. check for dc voltage coming out of the amp.. dc volts = bad then swap to ac volts and see how many volts its putting out.. if any.. double check the ohm load coming out of the box.. if its still 2 the woofers would have to be dual 2 ohm woofers if they check out take a 9 volt battery and run it to the terminal on the speaker box.. positve to positive and neg to negative.. keep it on there for a second. only long enough to see which way they move.. if one moves in and one moves out.. theres your problem.. if they both move the same way. well then your sol lol Quote 91 dodge colt gt.. 4 custom t600 15s audioque 3500d.1 tuned to 25 hz... stay tuned. blazer stroker 15 brutus bxi2006d terrible voltage drop 145.4@38HZ...
