magillaru Posted June 30, 2010 Report Share Posted June 30, 2010 I just installed my new Crescendo Audio 3KW, XS Power Battery, and upgraded my electrical (the Big 3) and the amp is hardly pushing the subs. I just replaced my PPI PCX2400 amp with the Crescendo. I have 2 JL Audio 13W7's. All the wiring is right, connections are good, HU settings are the same as before, etc. I just called my local car audio shop to ask them what might be the problem and they told me to turn the gain on the amp up, turn the bass level on the HU up, and turn the bass knob up. *I did not take there advice for all the obvious reasons! They also told me that as far as quality, that the PPI amp is a lot better and the Crescendo Audio amp is basically a piece of crap (in other words they never heard of it, so it must be crap - I told them it's a Zenon based board and it's basically the same as a Sundown amp - they had no idea what I was talking about). I was expecting this amp and all my new upgrades to knock the doors off, considering that the PPI sounded pretty decent when it was in there. I don't know what the problem is. I need help!

klee7013 Posted June 30, 2010 Report Share Posted June 30, 2010 check voltage make sure you got proper voltage- check all wires and connections to make sure they are nice and tight also make sure the gain is set to the output of your headunit Link to comment Share on other sites More sharing options...
magillaru Posted June 30, 2010 Author Report Share Posted June 30, 2010 Turn it up? Haha! Tried that, thanks though! Singer Alternators Team Asshole #anothershittysingerbuild Link to comment Share on other sites More sharing options...
Slawsen Posted June 30, 2010 Report Share Posted June 30, 2010 More info.. how you have them wired, what your gain settings are at, are you using bass boost? idk, like they said, voltage could be a factor, but if you aren't careful and it is voltage you'll have some fried hardware soon 00' Nissan Xterra Always under construction :] HU: Pioneer DEH3100-UB Mids & Highs: Kicker DS Component Set & Crescendo tweeters Mids & Highs Amp: Rockford 150.2 Subwoofer: 2 DC Audio LV 4 18"s Subwoofer Amp: Hifonics Brutus 2005d you been hanging out with jeff and dustin with that green paint? its yellow so it has to be loud.

Slawsen Posted June 30, 2010 Report Share Posted June 30, 2010 I meant the voltage your gain is at. You need to use a dmm and oscope when setting your gains.. 00' Nissan Xterra Always under construction :] HU: Pioneer DEH3100-UB Mids & Highs: Kicker DS Component Set & Crescendo tweeters Mids & Highs Amp: Rockford 150.2 Subwoofer: 2 DC Audio LV 4 18"s Subwoofer Amp: Hifonics Brutus 2005d you been hanging out with jeff and dustin with that green paint? its yellow so it has to be loud.

newls1 Posted June 30, 2010 Report Share Posted June 30, 2010 can you even get a 2ohm load with W7's???? I thought those over priced subs have weird VC options like 1.5ohm, 3ohm, etc.... I could be totally wrong here I love my staffie So anti FACEBOOK it isn't even funny Link to comment Share on other sites More sharing options...
