Alpine MRP-M500

[Qexler 10+ year member]

I have an alpine MRP-M500 hooked to my 1043d (10" type r)

in a 1.29 cubic foot box with a 20" flared aero port

Below is a photo of the amplifier settings.

The only thing I am confused about is the lp crossover setting?

Most amplifiers have lp and hp filters but mine is just the single knob.

What exactly should this be set at?

You should keep it set as low as posible

lowest is like 45-50 range, but it doesn't sound like it's hitting any high notes at all when it's so low is why

I ask this.

Its a Mono amp your not going to get those high notes from your sub with that amp

I would keep it set at 100hz or lower.

Mono block, no high notes, Is it's purpose solely super low bass?

Yeppers! Go for a 2 channel if you want your subs to produce higher notes but you should just upgrade you door speakers or 6x9s if you want midrange and highs

Theres nothing wrong with using a monoblock though? I mean it's meant for a woofer

You dont get what im saying but that amp is designed for Low notes on a subwoofer........... Subwoofers are not made to produces high notes... So yes that amp is perfect for your subwoofer.

I mentioned a 2 channel amp because it sounded to me like you wanted your mid and highs to be louder.... in that case you could aftermarket speakers and a 2channel amp to amplify your mids and highs //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif get it??

I see, as for amp tuning your recommending me to drop the lp filter on my current amp to the absolute lowest setting?

may I ask if its designed for a woofer only why does it's hz settings go so high?

this is a good place to start...

If amp is going to be used for a sub then set the lp between 80-100hz. If you are going to power door speakers with it then set the lp as low as it can go. Either way keep bass boost off.
