WTF spending 150 on headphones and 50 bucks on a head unit, thats *** backwards, you must've never heard a good headunit, or that boss wouldn't be everything you want.

Also Audiopipe =/= Audiophile in any way AT ALL.

Hard to tell much about an amp's setup from a pic, OP...especially wrt the gain setting. Like has already been remarked, whether or not it is really set correctly depends on more things than just being at 60% of max on amp's gain pot.

Turn that LPF down son.

Looks like he might have the LPF currently set to 80-100Hz, which is not awful. Turning it on to 180Hz like he was talking about doing would be very noob-like, tho!

[quote name='TaylorFade']Done or tested many loud trunks, have you? Because that's a load of crap.

At 2 ohms, that gain setting is probably perfectly fine. Especially since he's probably only got 2v outs (or less).[/QUOTE]

Everywhere that I've read or heard, and through my own personal experiences, has shown gains with subs facing the trunk lid. I've seen several in dept tests around the forums saying the same thing. Like I said though, that is vehicle specific, so maybe your set-ups don't show that. Don't need to be a jack ass about it brah.

And If he's got 2 volt pre-outs, he's probably fine. But he could just as likely have 4 volt pre-outs, it's not like they're unheard of these days or something. Even some of the most basic decks have 'em.

EDIT: Strike that last bit about it being more than 2v pre-outs... he's got a boss, he's lucky if he's seeing 2v. Gain is more than likely fine haha.



Again, @EpicMango if you already replaced the speakers... which you said you had.... and if they're any good, which I doubt since you buy Boss.... the sound can be greatly improved merely with some amp power (And especially clarity, since I'm willing to bet the processor on that Boss headunit is absolute shit), and some deadener. For most things in car audio, sound is improved with the install, more than the equipment.

What I was going to say, looks like it's in that range.

I wouldn't have been condescending if you didn't try to pass it off as fact. The fact is that a VERY small percentage of trunks meter better rearfiring. And most of those would benefit from upfiring if they cared to test or build for that. And I'm not just talking about my personal builds, but the 50 or so setups that I've tested and/or seen meter. You don't need a TL to know that either. All you need to do is take a look at all of the loudest trunk setups to see... how many rear firing? Zero.

Link to all of these "in dept" [sic] tests?

My personal car does a ton better rear firing. I think I can easily lose 3 dbs facing into the cabin. The reason those record vehicles are so loud is because they seal off the trunk from the cabin, creating a baffle. This will always be loudest, but will always take the most time and money. I love how mine sounds rear firing, and do not have the time or resources to seal it off. Maybe one day, but not now.

I didn't pass anything off as fact, and I made sure to note that tests were clearly vehicle specific. Just noted that from everything I'd seen, firing towards trunk was the best option. Unfortunately for both of us, I don't randomly bookmark everything I read so I don't have the links at hand. Rest assured they're either on here, cawko, or diyma. Obviously anything sealed firing into the cabin would be louder, but the tests didn't do that. It just covered every box position and noted rear-firing was best. Which has also been my results. I guess I'm just an anomaly, go figure.

The reason those record vehicles are so loud is because they seal off the trunk from the cabin, creating a baffle.

Thank you. I thought this was a given that we were not comparing to sealed off set-ups. Clearly you and I have exceptionally unique vehicles that benefit from rear-firing.

Oh I know. Back when I got the deck, and speakers, I wasn't worried about SQ, I just wanted something that could play music because before then, I had 4 speakers in my car, 3 were blown, and one was working but was almost blown as well, so I just wanted SOME music. I bought the boss deck, because all I needed was an AUX port. Thats it. I don't need ANY other feature in a deck.

My thoughts Exactly!

Anypics of the box from the rear of the car? What kinda dimensions?

Well that makes sense to me man, plenty fair there. Hopefully you're able to save up and get a decent head-unit though soon enough. A quality head-unit doesn't necessarily mean gobs of features. There's plenty good HU's for sale on this forum or others that I'm sure you'd notice a night and day difference in sound from. And what speakers do you have in the doors?

Box specs were 3.4cu ft tuned at 32hz

dimensions were 31x16x15

You really want pics? If you do I can take some. I wanna show off mah awesome system anyways

Chyeah, pics are always a good thing! Im interested, bc I also have a 94 and was wondering how close to the back seat you could get. You must be a good ways back off of it to be fitting a 15 vertically. I may be wrong thanks to the false floor thing that is saggin like hell when I brought the papemeasure out for a rough size idea in mine. I need to take mine out, trace it out on woods, cut it out and fabric it. So with that being said, I may be alittle off.

Give a full rundown of everything you got in yours. Im pretty curious. Oh, also, with a 3/4 ring, any idea what our max mounting depht is on our front doors?? And one more thing, I hadnt heard of until here pretty recent. I dont think we do, but Ill ask any way. We dont have that ELD do we?

 

[EpicMango 10+ year member]

Here's pics of my setup

Once again here is everything on this setup

Obsidian Audio 15' Dual 4 Ohm Subwoofer

Audiopipe ASPM-1500 1500 watts RMS @ 1 ohm amp (Wired at 2 ohms @1000 watts RMS)

Rockford Fosgate 4 Gauge Wiring Kit

Box is 31' tall, 16' high and 15' deep

3.4cu ft @32hz

In a 1994 4 Door Honda Accord

And I still have some trunk space

It's pretty cool when someone comes in and pesters everyone for advice and actually takes it and posts a small review/build log. Thanks, OP.

Lets go in Order //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

1. You can tell in the pictures how far the sub is from the back seat, its not a lot.

2. I would not know the mounting depth in our Front Doors. I tried checking Crutchfield since they can actually tell you what speakers will fit in your cat, but I couldn't find specific depth measurments..

3. I do not know if we have an ELD or not. If you plan on running anything more than 1000 watts on full tilt, you are going to dim. I notice that on one of my lowest yet hard hitting songs, that I dim quite a bit when I really wanna flex the sub. But that only occurs on the really really fat bass farts. And thats with my not so efficient ASPM-1500..

I hope this helps

Get 1 15 at 3.4 cubes or 2 12's that will work with 1.7cubes. But as you can see, my box is literally tucked into my wheel wells, so the dimensions of my box are literally perfect for a 94 accord.

Hehehehe. Heyyy, I was going to spend major money (for me) on a system, I just didn't wanna get screwed. I trusted you guys, and it definitely payed off. I am really happy with my system //content.invisioncic.com/y282845/emoticons/cool.gif.3bcaf8f141236c00f8044d07150e34f7.gif

The only thing I can see in your install that could do some improving on would be the enclosure. That port is very tiny. I would bet that a different enclosure would allow for overall better performance.

Other then that seems good. Glad everything is working out so far though.
