Alpine Type-R - Let Down By It

[chartman18 10+ year member]

Yeah. They (P1's) were gained all the way up (didnt know about anything, they were my first subs/package bass deal) so it was dying/amp was too after 6 months.

the type r's may be hyped a little much, but they are a decent sub. 2 sealed bounce quarters off my roof, so they have a little wang. they are definitely not the loudest thing out there, but i have been fairly satisfied. something is wrong somewhere. i'd check the power and ground and make sure you have the amped powered sufficiently. what guage running to the amp?

Everything is in working order. Its just hyped up. Probably because the idea of 700+ watts on a single sub SHOULD be better than 2 subs with no more than 400 watts max (P1's) but the type-r seems (to me) like its not as 'bassy'. It definitely sounds good and all, dont get me wrong. I was just expecting serious bass outside the car..

you said your P1s were all the way up right?

I would assume that it was a different amp since those P1 woulda fried with the gain at full tilt and him blasting it. I would say check your HU settings, then your amp settings and lastly try a different box. I think the reason the P1's may have been louder was because your were pushing them to distortion while now the Type R is actually playing clean bass and handling the power well. For example, have you ever noticed that if you swap out some factory speakers, the aftermarket ones seem less louder? Its that that they are less louder but the distortion is no longer their.

Yeah, the P1's were running off a Rockford P325.1 amp.

Can anyone tell me if the subsonic, gain, and frequency on my amp is good? PLEASE.

If so, then is it ok to adjust the bass, treble, etc on the head unit after or will that hurt it?

As for distortion, thats true.

If you dynamat the whole car you cant expect too much bass to heard outside the car

What are they set at? Subsonic should be set somewhere in the range of 10hz below tuning. Gain depends on ohm load and power output of amp. and Frequency? I'm assuming you mean low-pass...from 60-80 would be ideal

I still say that a different style box may be in order.

And you should get a dual 2 ohm version and run the amp at 1 ohm.

You should have never expected the R to be a big improvement over the P1s.

Let's look at the numbers for a sec.

Two P1s with 300 watts each would be as loud as a single Type-R with about 1200 watts. Just going by the numbers the Type-R should be about 2 dBs or so lower than the P1s at around 700 watts.

edit- Just saw that you were running 300 watts total to the P1s.. in that case the R should be very slightly louder, but almost unnoticeable.

edited. I gave the crown to the Type-Rs by a hair.

EDIT: My bad, you said P1's. They were in a dual 12" sealed, 1.25cu.ft. each. It gave me the kind of bass I wanted where people hear me coming down the street. With my Type-R, I cant really get that at all.

I love my Type R system... //content.invisioncic.com/y282845/emoticons/naughty.gif.94359f346c0f1259df8038d60b41863e.gif U can hear it a lot louder inside, thats what matters to me.. Fuk outside, ppl will mess with my car. //content.invisioncic.com/y282845/emoticons/eek.gif.771b7a90cf45cabdc554ff1121c21c4a.gif

You know what, your right AJ. I have to agree with that now kind of. I just guess Im an attention ***** and want people to know/feel Im coming their way, lol. I still kinda want more bass somewhat. I honestly dont feel like making a another box for my Type-R unless I have another sub, so then I'd just make a new sub box for both the subs.

Ok, someone said the Subsonic should be around 10hz below my box? That'd make it in the 20-25hz range then correct? Ok, its set around there currently.

And for Low-Pass frequency, the same person says the range should be around 6-80. I believe Im around 120hz currently. I guess I should turn that down towards 80.

As for gain, the ohm is 2-ohms, and the output at RMS listed is 1,100, but I really dont know what its really putting out. I was reading the gain setting pinned thread before I set this up, and it supposedly said at 1100 watts, it should be about 46.9 volts. Any ideas?

Anybody have any more tips/suggestions/help?

Thanks guys.

PS: Why did a couple people tell me to rebuild another box, when the majority of fellas on here recommended 2.5 at 32 hz? Shouldnt that mean its the best at that?

 

[SPL_Lancer]

I dont know about 2.5 @ 32Hz, I have never tryed it. But I do know that 1.5 @ 30-35Hz sounds good, and goes qute loud.

Is there any way the mods or something can remove this thread and put it in the Subwoofers category forum threads? lol, I cant believe I messed up on that and its so weird in the speaker category.

I have never heard a P1 but I used to have a P3 12' with 750rms running into it. I then replaced it with a type R 12' in the same ported box and with the same power and the Type R was louder to my ears.
