Bass cuts out.
Hey guys,
Got a question for an expert.
I'm running two Alpine Type R's (500RMS each) off an Alpine PDX 1.1000 (1000RMS) in a Sealed box (not for long though).
But my question is, my bass just stops once i get to a certain level; It's still loud but there is definitely more in the subs as they just stop, and i have to turn the HU on and off to get them back.
I think it might be due to a lack of power getting to the amp?
Stock Battery, no Capacitor, Standard Alternator. 4gauge wiring all the way through.
Anyone able to hint at what this could be causing this?
One mate told me to get a bigger battery, another is saying alternator upgrade and Capacitor.
But An Expert opinion would be rad.
let me know if you need any more info, or pictures, or what have you.
Heres a link to my car with all the exact products inside.

Capacitors are just a dangerous band-aid, they don't fix the actual issue.
Are any lights coming on on the amp? Sounds almost as if it's going into protect mode.
How are the subwoofers wired up? What independence are they resulting in?
Capacitors are dangerous now? I can understand them not being used for certain issues but claiming they're dangerous?

Sounds like a power issue? My mate had the same problem

Umm, I dont know my wiring terminology, but theres two seperate wires, with the banana plugs connecting the dual voice coils. The Subs aren't connected to eachother at all.
Not too sure on impedence, I think it results in 2ohm, but i failed physics, and it was a while ago in which i did. Hence needing an expert
That PDX amp is a mono, so even if the wires aren't connected near the subs, contact near (or even on the terminals of) the amp will mean they are wired 'together'.
Are you able to have a squiz and draw an accurate diagram of how the wires are connected? Or give a detailed description of each input/output?
The Amp has 2 plugs, which i've run individually to a sub. 1 plug for 1 sub.
If this isn't suffiecent, let me know and i'll go take a picture for you.
And the right hand side is the banana plug on the sub for the dual voice coil.
MS Paint liek ah baws
Your mate has something set up wrong.
Their are 2 types of Type R subs, dual 4 ohm, and dual 2 ohm ( i think i can't recall) so we need to know which one's you have. Once we know we can tell you how to wire them up. Otherwise you might be presenting the amp with an unsuitable load.

btw your drawing sucks

Pretty sure my drawing rocks.
And they're Dual 4ohm.
Well if they are dual 4 ohm then you haven't got a 2 ohm load going to the amp, it's either 1, 4, or higher.
What's with the speaker outputs on the PDX amps, is it just pos and neg? I've never played around with a pdx amp so so you'll have to help me here, i'm unsure as to why there are 2 outputs on a 1 channel amp. But if they are just positive and negative and you said your subs aren't connected together then there's your problem your amp will be going into protect mode because of the load.
You need to wire the voice coils on each sub in parralel, and then wire the subs in series to get a 4 ohm load. According to Alpines website your amp puts the same power out at both 2 and 4 ohm.
I like your attempt to belittle me, but if installed incorrectly they can explode, have a google. I classify something that has the potential to explode in the hands of an uninformed person quite dangerous.Capacitors are dangerous now? I can understand them not being used for certain issues but claiming they're dangerous?
Is it wired like this to 4ohm:
Or like this to 1ohm:
Or something different?

Use the first picture in the above post, this is how you have to wire up the subs. Then you will get your full 1000wrms.

Ah okay.
I've got the banana plugs going from + to + and - to -. (Like it the second pic, but each wire goes back to the Amp, not the other Sub.)
So i just need to switch those around.
I'll give that a go today and let you know if it works!
Thanks Guys, Much Appreciated.
Haha, it wasn't to belittle you, I just don't see the point of you saying it. From your other posts on here, you're clearly biased against capacitors and now have added that they're dangerous to your comments about them. It's just amusing
Still wires them in parallel, producing a 1 ohm load which the amp obviously can't handle
Problem should be solved if you wire them like the 1st pic
Well yeah, I don't see the point of recommending a fairly expensive piece of equipment as a band-aid when it's often cheaper to fix the actual problem (Big 3 upgrade etc.)Haha, it wasn't to belittle you, I just don't see the point of you saying it.

Congratulations Internet.
You remain world champion of everything in the history of things.
Please come to the counter to claim your prize.
But seriously, you guys are amazing!

Yes, yes we are. Modest too.
