what do you think about the amp? are you happy with it? i have done the big 3 but i used 1/0 gauge from home depot electrical wire. i used 1/0 welding cable to run from my battery to my amp. a guy who owns a local car audio shop took a look at the wire i used to run my big 3 and said it's no good b/c there are only like 8 big strands instead of hundreds of strands as there is in audio and welding cable. so i am going to redo my big 3 with 1/0 welding cable. damn must have been a bitch to get that wire where you wanted it. imo if its already done dont change it. nothing wrong with what you have. the only difference in strand is how flexible it is. i think you should start with an extra battery and see how that works out Ok, I will do that. I was told I need to get an isolator and a capacitor. does this sound right?

when you say 3500, are you talking about a battery?

would you recommend getting a h/o alternator instead?

Ok, what would the other run of 1/0 be for? The ground going to the back battery?

Hello, I have a Cresendo BC2000d and my headlight dim bad when it really hits. I'm wondering what else I need to run it properly. I have upgraded the big 3 with 1/0 wire and have the amp hooked up to 1/0 wire. I have stock battery and stock 130 amp alternator. The amp runs at 14.8 volts idle but when it hits hard notes I know the voltage drops because my lights dim BAD. What should I do to fix this? Just upgrade to a better battery? Add another battery? Upgrade alternator? Thanks

In my case I was using bass boost with my PPI and not my Crescendo. The difference is with Crescendo the bass boost frequency is 45 or 48 hz, I can't remember which. On thee PPI there is a unique feature which allows you to boost the bass at 4 different frequencies - 30hz, 36hz, 44hz, and 60hz. I had it on 30hz boost. It stink that you can't do that with newer amps, pick the boosting frequency. But the PPI seemed like it was louder and sounded better although the Crescendo was much more powerful.

I'm in the same boat as you. I have 2 12" Kicker CVX dual 4 ohm and I did have them hooked up to a PPI PC21400 bridged at 4 ohms running 1400 watts. It was loud. I wanted more power so I bough a Crescendo BC2000d and wired my subs down to 1 ohm. So you have 1400 watts out of PPI (probably more) vs. 2400 watts out of the Crescendo.I swear the PPI sounds better and louder. Is it because the PPI is a class AB amplifier? Maybe someone could help me out with understanding this.. Tony

Nothing here

dang where did you get that thing? how old is it? looks ancient....

try re-posting that pic again please

thanks skittles. i typed that wrong, i was using a bass remote knob previously with my ppi amp. i am not using the ppi remote bass knob with the crescendo. but you did clarify what the knob does now and how it should be set and used. what about this phase setting? i have never seen this on an amp before. and like you said i think, should i keep the bass boost on 0? thanks

Ok. My previous amp (PPI) has a remote bass boost know at a certain chosen frequency. I was using that knob with the crescendo as a bass boost knob. so does the remote knob override the settings on the actual amp?

WHAT??? no, dude... no. and you don't need to turn the sub level up any on a pioneer. i have always left mine at 0. alpines you need to turn all the way up.adjust your subsonic just below the tuning frequency of your box. it's there to protect your subs, use it. put bass boost to 0. it might be boosting a different frequency than 40hz. so when you test at 40hz, you get a good set point. but then when you play music that has content where the bass boost has boosted, you get clipping. is the remote gain all the way up when you tune? turn the LPF down to around 80hz. thats more preference but it will help with clipping a little bit. oh, and yes, that power wire is definitely hurting you. just to test it though, play a tone and turn it up to be just shy of clipping and then measure input voltage at the amp. I'm a little confused on the remote knob. The manual says it's a bass boost/remote gain. So which one is it? And thanks for all the input guys....

i have a pioneer avh-p3400bh. i have 1/0 wire for my big 3 but unfortunately i have cheap dB link 4 gauge wire going to the new Crescendo. it doesn't even look copper. i just ordered some 1/0 welding cable i'm going to run instead. do you think that is the problem? i have the bass boost set about half way when i was setting the voltage. head unit has equalizer and the lower frequencies are at like +2 db. Have the LPF to about 125htz. subsonic i didn't touch and phase setting i didn't touch. i just took an ohm reading and i do have them wired at 1 ohm. the multimeter read exatcly 1. so that narrows problem down.
