Sub Cutting Out At Volume

[Space Ninja]

Hey guys,

Just had a quick question - I've got a little issue with my sub in my car at the moment - when I go to turn the volume past about 15 on my HU the sub works on and off but cuts out. I've got it attached to an 800W Pioneer Monoblock Amp and the Sub is a Clarion Pro dual voice coil.

I'm not sure what I can check out on it to be honest, the power cabling for the amp is very good and I never had this problem with my old sony sub (untill I blew it up though....)

any ideas ? if I can't figure it out I may take it over to Chris at audio express to have a look for me.

I would check to see if your rca's and remote cable are firmly connected, at a guess they might not be up to all the vibrations, then sit beside the amp and watch if it has a power light - see if that goes out

yep run it past (ring first.) and I'll have a look.

Cheers Chris, I'll try to give you a call tomorrow.

I just checked to see if the amp is cutting out, and its not, its just the sub, power seems constant to the amp so it must be something else.

[Chris Rogers]

unsure - will have to look at it.

Hello there,

It sounds more like ur drawing too much current out of the power side of ur amp. Is your voice coils parralelled or series, and what ohmms is it then. If it dual 2 ohmm voice coils in a parralell connection (positive to positive) (negative to negative) u will have a one ohmm load and ur amp will get hot and cut out at half volume. Most mono block amps can run 2 ohmms minimum.

Good Luck

only suggestion check all wiring is secure, maybe one of the wires inside the box is loose, or check your ground to monoblock is same size minimum as your power, not having a big enough ground will cause it to cut out, also check your rca cable, play with the ends of them and see if they cut out when you wriggle them, if its none of them may be... the devil is in your car

it was s fuse probelm to my understanding - I gave him a new fuseholder and it seems to be fixed.

alot of amp have a cutout if the is to much gain coming from deck, try lowering the input on amp and adjust more volume from deck. This is commewn with 3-5 volt pre outs
