Will this amp and dual sub setup pound my chest?

You say that because you've never experienced loud and Jeff says what he did because he has become immune to loud.

At the end of the day, you don't need to impress us.... if you throw in your favorite CD and it puts a smile on your face you're doing it right.

True.

So I picked it up today. The speakers sound like a whole new setup and are absolutely beautiful... The subwoofers hit just as hard as I need, and I can tell they are brand new and stiff... Can't wait for their full potential to come out. He said the DSP tuning they did made no sense at all, and he's got this system sounding like it's worth every penny and then some (helps that it's in a newer model VW GTI with tons of dynamat so it doesn't have that ghetto shake anywhere). Anyways, I think people really underestimate alpine type R's. They are ridiculous, at least from a daily drivers perspective, any more and I would surely damage my hearing beyond repair.

Hats off to Rainier Audio in Tacoma WA!

Wrr
Yes sir! Double bass pedal attacks make me happy. I do not think OP was being literal. I disagree with you regarding sealed boxes and kick drum extension. I get great results in those parameters using nothing special. Could it be sea elevation or lower wattage? No idea, but we will find out in a few days when his new setup is up and running.

you'll find me up front and center in the concerts so i expect that kind of bass kick in my ride. I never said anything about extension I mainly focused on the impact aka the chest pound feeling the OP was stating. I've heard all sorts of sealed setups. Non holds a candle to a smaller sub in a 1/4 wave transmission line box when it comes to accuracy and impact. a single 8 on 500 watts will beat out any two 12s sealed on 2000 watts all across the board in usable bandwidth, spl, and accuracy. The group delay aka overall accuracy is much better as well. You might want to transition to more advanced boxes in your next boxes. . The enclosure design is everything and T lines are absolutely killer. Sealed boxes, you are literally at the mercy of your vehicle cabin gain, you rarely get a real flat response, you just get a rolled off response with a high peak in your car's resonant frequency which is far from SQ imo. In my 6th order wall i can play from 25 hz to 65hz flat within 2 db variance and will have slow roll offs after that. In the dual 15s T-line I've heard it was legit flat from 17hz to 70hz with half a db variance from our testing, crazy blend for metal but can also play slowed rebassed songs for hair tricks as well.
For reference, you'll have a 6-10 DB variance from 20hz to 60hz with most sealed boxes.

With boxes with any kind of port or horn, you can factor in your vehicle acoustics in the enclosure design process to achieve greater SQ, combine that with modeling out responses from your electro mechanical parameters aka ts parameters, you'll achieve results you would never have imagined you can ask @shredder2 how modeling softwares changed his whole bass life lmao. With sealed boxes, you are stuck with the response you get unless you start EQing with a dsp to flatten peaks but you give up output with that. I'd rather have full flat and powerful response off the bat.

Once the subs break in I may look into a ported box, if you think it would make a ridiculous difference with the amp and subs I have... I would be willing to sacrifice valuable snowboard and mountain bike room.

if you are happy with what you have, dont change anything. You get numb to bass really easy and you just fall straight into a money sink.

$4000!? That included the price of the car, right?

900 for GTI mk7 harness and head unit. Like 1400 in new amps, and 700 for subs and box. Thousand in work to rewire and fix the **** tuning of the focal speakers and mosconi dsp I kept made sense to me. Worth it worth it worth it. Rather spend money once to get it done nicely and under warranty than to **** up and blow **** or get terribly matched pieces myself until I learn.

Im glad you like it. Enjoy it for a while until you get that itch again lol. What I would do (if possible) is to watch videos on car audio or hell even go to the shop and hang out and shoot the shiit (if they let you). I did that at my local shop and they would give me fuses, rcas, 1/0 wire and all kinds of odds and ends for free. I just brought some beer over as a thank you haha. I went from letting my neighbor install my setup when I was 16 to learning how to do it all myself and now get to spend on better equipment as I don’t have to pay someone to do it. I don’t know the ins and outs of the technical stuff (yet) but that’s is what I’m trying to learn now.

Anyways, I think people really underestimate alpine type R's.

Alpine Type R has been known solid for ages. The subs can get loud and the components sound really nice. The type R can hang with a lot of far more expensive brand name stuff. Type X is even better but very spendy.

The issue you'll have here is that a lot of the DIY crowd buys gear from companies that are one guy in a garage selling cookie cutter stuff from China with their name brand on it. Depending what you're after and if you do not need to rely on brick and mortar service or support they're getting a lot more bang for their buck. On the other side you have the snobophiles who will scorn you if you're not paying at least a buck a watt for power and run esoteric boutique brands with outrageous price tags and a head unit with a copper chasis.

Anyway, like I said before, if you can put in your favorite CD and it puts a smile on your face you're doing it right and it sounds like the guys at your local shop will look out for you if anything ever happens so there's definitely value there. You bought good equipment that you can expect to last a long time and perform well along the way. If you're happy don't change anything. Ported box would give you the equivalent of about 1 more click on the volume knob more output and possibly a bit more low extension but if your music sounds good now best leave well enough alone.

Definitely bringing them some thank you items, but with nothing to expect back except the same awesomeness they've already extended doing regular business.

I must admit I am intrigued. I have yet to hear a sub setup the plays that wide. By your description a 1/4 wave t-line sounds pricey. I might build a box after all. Thanks.

 

[OldFartAudio]

Glad you like it, I would have been surprised if you didn’t though. Have fun with your new setup and take care of those installers.

 

[Tattooman]

I can’t imagine what I’d be able to do on a $4k budget haha. I really hope you enjoy the setup but $4k for that is crazy expensive. You live and learn though so next time, come here first.

Come where? Where u located?
