isnt the amps fault, thats user fault.......do everything these people have suggested. wire that ****er to 1 ohm and just be easy on the gains. get ur crossover set right, make sure ur box isnt a POS. amp's working, its just not set right....

Will that amp run 1 ohm daily? The 2500 is rated at 2 ohms...i take it you bought the amp after the subs, well you should have got a 1 ohm stable amp with 2 dual 4 ohm subs. Not to mention that big of an amp requires a hella electrical system...probably coulda got buy with an ed nine.1 or something similar for MUCH cheaper and better on your elec system...

I didn't read past the first post, so forgive me if i mention anything that's already been said.

I'm willing to bet that the subs are wired wrong //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif If not, check your head unit and amp settings.

run the amp @ 2 ohms not 1 ohm. The amp can handle 1 but its not recommended and if you're having issues already you def dont wanna go that route lol.

hope everything works out.

we were able to do a 51.x in MECA last year with 2 L710s. The amp is very solid and reliable.

My buddies all have systems and I wanted to be the best. I have had luck with kicker before so I got a zx2500.1 and wired it to 2 s10l7's. It just doesn't sound good. The woofers fart at higher volumes, btw it it wired to 4 ohms at the amp which as I understand should be perfect. I have a diesel so I have two batteries putting out over 800 cold cranking amps, and I am running 0 awg wire from the battery. I also have a I believe h600 but as Im told is equal to 100 farads. I'm just mad because when I plug on of my subs into my buddies american legacy amp which I've never heard of one sub pounds twice as hard as both in my system. On top of that my other friend that has an sx650.1 and two cvrs pound harder than mine. Sorry for the long message but I wanted to be thorough. Any help is appreciated.

Simple.

It's because you touch yourself at night.

Bad Box FTL

dude....my amp has teh same board as urs, and itll run 1 om daily (.7ohms dcr) off 12v all day long. you need a better box, correct wiring, and to tune it right, only 3 knobs, it wont be that hard. bass boost all teh way down, set the crossover to around 70-80Hz (even better if u can do it on ur HU). and adjust that gain with a DMM get at least 1 battery up front and one in the back for the amp, if not a complete eletrical system upgrade

I appreciate the help but it seems like some of you aren't reading what I wrote. The box is fine it sounds good on another system. The subs are the correct ohms. I am not going to run the amp at full potential the subs will never last. In addition to that I plan on adding 2 more subs which would be the recommended setup. I took my truck to Sun Valley Stereo and they are gonna look at it in depth. When I took it in they glanced at it and agreed that everything looked ok but there was just something missing when we listened to it.

Turn the crossover (x-over freq on the amp) ALL the way down, to 50 hz.

And wire it down to 1 ohm, just turn the gain back some so you don't blow the subs. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

You said you had 1 sub hooked up in another car, that is a big difference. I would bet that you either have too small of a box or one sub is wired out of phase.

Thor200587 do you want to meet me at Sun Valley Stereo around 5:30 today when I get off of work. I want to hear what it sounds like. To me it sounds like the RCA signal that your amp is getting is what's causing the issue.

I can pull my RCA cables out the back hatch of my truck and we can plug them into your amp to see if that helps.

I've had a couple Kicker 10" L7 4ohm DVC's laying around my garage and decided to put one in my truck last night so I can have bass while I wait for my 18" BTL.

I originally had a 10" JL installed in this 2 cubes @ 28hz box which I was using for my Home Theater, but last night took out the JL and made the cutout hole square and popped in the 10" L7. It actaully sounds very clean, deep and loud even though the box is tuned more for Home Theater's and is too small for the sub in comparison to other ported box's that people have built for 10" L7's on caraudio.com
