I need a guy who knows car audio

[83countrysquire]

I got two sets of cadence cwm6-kit wired to my vx4004 planet audio amp. Each channel running to one speaker. It says the speaker can handle 100watts rms and that is wat the amp puts out each channel. The speakers peak at 200watts I believe thats what the amp peaks too. But when i crank the volume with a mid bass range the speakers start to pop. What could be my problem?? Anyway i could cut the power i run to them?

The "POP" is the speaker's cone/suspension running out of travel. You can keep the power level up, but you must raise the x-over cutoff. Your amp has an 18db/octave cutoff, but it is only a low pass x-over. So, at this point you are probably asking the speakers to reproduce what they were never designed to do. Are you running subs? The VX 4004 is better suited to someone not running subs, or using it to power only the subs as there is no high-pass x-over.

From here, you can reduce the power levels, or wire in a passive high pass for the midbass drivers.

Well is there anyway I could adjust it so that it doesnt do that, i will be running one sub soon but I still want to wire the subs off the same amp was thinking about running two channels on one but it would throw off the balance, heres a pic of the adjusters i got

You could run a passive high-pass filter. I would aim for 80-100hz for a 2nd-order passive filter. Go here on how to wire it:

will these work? http://cgi.ebay.com/ebaymotors/_Car-...1%7C240%3A1318
or would this be a better choice http://www.parts-express.com/pe/psho...00&ctab=1#Tabs

[torquelover]

The first link would work, but you can do it yourself for less money. All you need is a capacitor wired inline. The second link is for a low pass crossover, exactly opposite of what you need.

[83countrysquire]

So this would be my best option wired inline with positive wire. http://www.parts-express.com/pe/psho...number=027-374
But i cant find the one that is best for audio quality in that size. But I assume this will do.

This. I need to flip my HP filter on, I get a bit too much bass trying to reproduce out of my little 3.5" front speakers. The adjustable controls on the amp are nice, you can just tweak it to how you need/want.

Additionally, most newer head units have built in adjustable crossovers.

[83countrysquire]

man how i love you guys always so helpful to me especially mrltd always been helping whether it be crazy pipe dreams or things I actually gonna do.

[mrltd]

Yes, I occasionally can be a helpful asshole.

Unfortunately mine doesn't. It has a crossover, but no adjustment which is really stupid.

[torquelover]

So, there is a high pass on there? Did you try it yet? It did seem odd to not have one if it had a low-pass.
