Alpine Type-R - Let Down By It

[CrEaTrE 10+ year member]

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.

2.5 @ 32hz is perfect, its not the box unless there is a leak or something.

Yeah, theres definitely no leaks in my box. Me and a buddy made sure the screws, glue, and caulk to in the right spots and such.

I guess its just me and my high expectations. I shouldnt have done that, but its just the RMS wattage compared to the P1's, make it seem like its going to wang much harder. Its definitely sounding more clear/quality than the P1's, thats for sure, and it hits harder/louder, but I just wanted a teeeny weeeny more bass, lol. A second Type-R should fix that correct? With the same amplifier powering both Type-R's?

What kind of box would be perfect, but not too large for 2 Type-Rs, Bxi 1606D amplifier powering them, in a kinda-ok-sized trunk? Max heighth is like, 14-15 inches, width is like no more than 34-35 inches, and the depth is like no more than 18 ish inches? I didnt really see any in the Box Plans thread.

PS: As for creatre above me, I dont see how he can how 1 ohms, on 2 4-ohm subwoofers? I thought it was only 2 ohms max.

Your are being let down becuase your a total basshead. Your first setup took 2 low end subs and maxed the gain out on an amp. You were pushing quite a bit more power out of that older amp than you think you were. RMS only refers to a NONCLIPPED signal, you were probably putting out 1.5x that, while pushing those subs to their limits. Sure it sounded like crap, but I'd bet it did get quite loud for what it was, even if 20% of it was distortion, which also adds volume! Try tuning your box higher, if you don't care about musicality it will at least be louder.

 

[chartman18 10+ year member]

Hmm, your right. I dont know if I feel like building a new box to 'tune' it higher for more loudness, just built this one, so Ill have to stick with it until I get another Type-R, then Ill build a dual 12" subwoofer ported box. Whats a good box in cu.ft. and hz for a dual Type-R? The current box I have now is 2.5cu.ft., and it pretty much almost takes up my whole trunk, it can go back at least 3-4 more inches, but thats it, and the sides, about 2-3 inches. Heighth is 14-15 inches max.

how bout you post some pics?

and try setting your gains properly?

and anyone who wants to be loud outside their car //content.invisioncic.com/y282845/emoticons/ban.gif.ce8465566702ef9f72e97e794ed1c86a.gif

Haha nice about the ban thing. I just said earlier that the dudes right about it not being loud on the outside, I agree with that now.

As for pics, I can take pics of the amplifier settings/tuning sometime for you guys.

As for setting my gains properly, I have a DMM, and its really confusing, so Im working on that buddy.

yeah, i'm usually not too critical. if i don't like someone i just don't post.

but you just came off as kind of a noob talking about maxed gains and being loud outside the car.

i'd start by setting the gains correctly and then seeing how it sounds.

just remember:

all HU settings at 0

HU volume about 3/4 up (and never turn it past the volume you set the gains to)

bass boost on amp at 0

subsonic filter and low pass filter as mentioned before (20-25Hz and 60-80Hz)

then set your gains (go for a voltage around 45V AC) using a 40Hz (or so) tone.

i suggest you go for the -3dB level.

what you really should have done is purchased the D2 version of the type r and wire to 1 ohm.

same price, same amp and you get more power //content.invisioncic.com/y282845/emoticons/rolleyes.gif.c1fef805e9d1464d377451cd5bc18bfb.gif

Someone may have already said this but I didn't feel like reading every post. When you say P1 are you referring to Rockford Fosgate? If so basically all they are is PA speakers. There is definately a quality difference. They produce bass differently than a high quality woofer. High quality woofers are designed to give a smooth bass response. The "cheap" woofers tend to have peaks at higher bass frequencies and those are the frequencies that can really be heard outside of a vehicle. And as for your box, it seems a little big for a Type R if you ask me. I would have figured around a 2. I had some of the old ones and I think they recommended porting at 2 cu ft. I really don't like the sound of woofers in vented boxes.

Another thing, just as xluben said, get your gains set right. The rule of thumb is head unit at 3/4 volume before distortion starts to play a role in sound. Of cours I can go to full volume on mine and have no breakup in the sound //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif Also don't use loud buttons and things of that nature. They were meant to be used with low volume levels.

chartman18, too bad you don't live by me.

I got lucky with my setup, it travels hella far and sounds amazing outside of the vehicle.

At least 10-25 people have made crazy comments like "OMG you were shaking the windows of my house when you pulled up", and "wow I've never heard anything like that before", and my favorite "Holy shi† you were shaking my mirrors and I was 2 cars in fornt of you!"

I say get another sub and try to build a box similar to mine...

nice amp. i'd be kinda afraid to have it mounted for every thief to see it though. nice looking box as well.

Thanks!

But good luck with theives being able to see it I have (2) layers of 5% limo tint and the factory privacy glass. No way they can see it even with a flashlight, I've tried. Plus I've epoxied all (4) of the double nutted bolts that hold the amp to the mdf plate that has (6) bolt's attached to the steel tubing which is attached to the frame of the truck //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

limo tint is the shit.

Distortion made the other speakers sound louder to the ear, is my guess. Clipped signals are horrific., temp3st called it imo.

 

[chartman18 10+ year member]

Hey, thanks all for the advice. I know all about keeping the H.U. at 0, bass boost off, etc and such. All I needed to know was the Gain setting and where that should be set at. I just dont know how to work a DMM well lol. I will definitely be getting another subwoofer and another custom box, one that fits my trunk, but also to caraudio fans specs and such. Any ideas for a box? I didnt see much that would fit in my trunk on the Box Plans thread.
