What do I do now??

[powerstroker 10+ year member]

Ok, so it looks like I may have to send my amp off to get repaired. It is a Crossfire XP600D, and I am getting no output from it. I have the blue "good power" led, but no sounds. I am running 4 awg Knu Flex and have a good ground (frame rail, less than 15'' ground cable). I have checked the rca's and remote wire (neither are pinched, cut, etc.), and my HU settings are correct.

I really wanna get some music playing, and am thinking about buying a used amp from here to run my 4 new Sundown E8's @1 ohm. I have seen a couple of amps on here that were relatively cheap. (Hifonics 750W mono amp, Fusion 100W mono). Should I wait it out and get the Crossfire fixed? Or should I get it fixed and buy one of these to get me by and then sell both of them and buy a Sundown SAE1200D?

Thanks for any replies, and possible suggestions for getting my Crossfire working.

EDIT: May be a REALLY DUMB QUESTION, but could the fact that I don't have a remote gain knob be the problem, ie; gain is turned all the way down, and I have no way to turn it up? Or should the gain control on the amp override it when I turn it up on the amp?

i would just buy a new or used amp what kinda power are you needing and at what ohm?

Do....whatever you like. If you wanna get another amp soon anyways just save the hassle and buy that.

Kinda what I was thinking. Thanks for the reply.

I was hoping to buy an amp to get me by, then sell them both when I get the Crossfire fixed. Maybe throw a little cash with it and by the Sundown.

I need it to be one ohm mono stable.

The subs are S4's, and I have 4 of them. As far as power, I really don't know. I know the subs are 200wrms, but I have read a lot of guys putting a lot of power to them.

I am running them in a sealed box, built to specs that Sundown gives. I am thinking maybe 800-1000wrms@1 ohm.

THANKS FOR THE REPLIES.

You can't take a screwdriver and turn the gain up on your amp?

I'd just buy the amp you want.

I'm sure there is a used one for sale on here somewhere.

Yessir, I have done that. I was just wondering if ......dumb question alert!!!!!!.......maybe the knob was turned all the way down before it was removed, making the gain be turned all the way down, and not adjustable by the gain control on the amp until the gain was turned back up with the remote knob.

 

[andrewmoore13 10+ year member]

Amp > remote.

the amp gain will override a remote. From my understanding a remote knob will just allow you to adjust UP to what the amp is set at and once its removed it will revert back to the amps setting.

I think it's just supposed to make it easier to adjust on the fly.

Thanks a lot. I was kinda thinking that, but wasn't sure.

Any ideas about what may be wrong with the amp? What about the Sundown SAE1200D? Too much power for those subs in a sealed enclosure? Would I need to upgrade the alt. to run that amp? (Ford Super Duty diesel)

No, you wouldn't need to upgrade your alt.

I would suggest going with the Sundown if you can find a used one or swing the money to get a new one. The subs in a sealed box should be able to take the power. I wouldn't sweat it to run 300+ to each; you can always adjust the gains to reduce power if you need to.

What is your budget for a new amp? What do they want to charge you to fix the old amp? Likely going with a new amp would be a good way to go, but before you do that.... have you replaced the RCAs with another set to see if it is just bad RCAs? RCAs are known to just "go bad" without any apparent physical damage. I'd try that first and foremost, then if that's not the problem I would probably just buy a new amp.

Ok, I will go pick up another set of RCA's tomorrow.

I called Crossfire and they said that it would more than likely be covered by warranty (very nice folks by the way). I can comfortably spend around $250-$300 for a sub amp, but I really would like to get this Crossfire working. Hopefully, it's just an RCA problem. Can I test the RCA's with a volt meter?

If I can't get it going, I will likely buy this amp unless you guys point me in a different direction.

If you play a 60 hz tone and use your DMM on AC voltage and you get a few volts then they should be fine.... Likely easier to switch them out though //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

Ok, thanks again. I guess that is what I get for using cheap a$$ rca's.
