Hey guys. I just bought an 06 RX-8 about 2 weeks ago. I got recommended to a guy who builds custom boxes and would like to pay him a visit soon.

Before I talk to him though, out of curiosity, what would you consider the best bang for your buck setup in terms of an amp and 2 subs? I definitely want/need to keep it under $1000, and will take any suggestions.

From what I understand, some also let you control the amp's output level from a remote-control type device. I would really like this as obviously the RX-8's built in CD player doesnt allow for that.

Any help is appreciated.

i have on 12' alpine type r and the alpine 450 amp and i love it i got it all for 600 and it hits hard. you could go with im thinking you could get 2 12 type r's (220 a piece) and 2 650 amps (300) for around a 1000 if you use ebay.

well if bang for your buck you mean spl i would go with a hi fonics amp probobly the bxi2607d ....onlinecarstereo.com, these amps are alot of power for a pretty good price. i would recomend two ten inch subs in a ported enclosure. the reason i say 10's is because a 12 inch sub will have a larger enclosure and if its ported could be very large and two enclosures like that probobly wouldnt fit in the trunk. also two 12 inch subs might be two much as far as efficency is concerned. i would put each 10 inch sub in a single enclosure that are rear firing. leave a space betwee the two boxes and take out the divider in between the two seats to let a little more sound get through. have the vents for the ports on the out side of the boxes close to walls of the trunk with the subs next to the gap youre going to leave in between the two boxes so the sound can travel through the space in the back seat.

the type of sub youl use is wide open. you should be able to find alot under 200 a piece since the amp is almost 600 bucks. THE TRICK IS TO HAVE A CUSTOM BOX MADE TO THE SPECS OF THE SUB. since you have a buddy that does that your in luck. you can have a top of the line sub sound like **** in a poor box design. but you could have a shitty sub in a nice box sound great. im not sayin 200 bucks would get you a shitty sub but if you did get one.....


good luck and do your home work

chase rx8 is right, my brother has two type r's and they hit. you might want to make that one of the subs you look at. but two of those amps will only get you 900 watts......that hi fonics amp is pushin 2600w @ 1 ohm .....youll probobly also need a capacitor and dynamat if you want it to impress you

One of these in a sealed box would be superior to two 10"s, IMO.

Or even a ported box if you wanted some serious SPL.



Edit: Though I will admit the Alpine is a nice sub.

More opinions based on what? Perhaps it might be a little better to find out the following.

(1) how much trunk space do you want to give up
(2) are you after a SQ (sound quality) based system or a SPL (loud) system
(3) are you going to want to expand it in the future
(4) do you want shat that you will be replacing or good equipment that you will keep
(5) do you want your system designed based on a educated and informed decision or a guess

ricky356

thats what i was wondering ...i just took a guess on spl because thats what bang for your buck sounded like to me............i took into consideration the trunk space leaving enough room for some items to be stored. the only thing he will have to expand on is the mids and tweets. the stuff i recomended is decent equipment that will run till he gets sick of it and wants something new.

however i dont think that 1 jlw6 800w peak 12" sub with a 500w amp will come any where close to 2-10" properly ported subs with a 2000+ watt amp

once again the subs dont have to be $400 dollar high end equipment. a durable sub that is cheaper in a proper box will perform great......two tens will push more air than a single twelve...add the inches up. 10 inch subs hit just as hard as a larger sub. they may not play as deep but the box shouldnt be tuned to an inaudible frequency anyway. which is really the only advantage a larger sub would have. think about it? do you ever hear of a a 10 inch sub not playing a note a 12 or 15 inch sub would??? so why would you use one twelve instead of two tens?? even a 15 inch sub has a less moving area than two 10's.

could you fit two twelves....... probobly. two ported twelves "which would perform more efficently"....probobly not. two ported tens yes! with some trunk left!

I agree with ricky on the hifonics amps. they are definitely awesome. Every one that is tested by car audio magazines say they are also pushing out more power than is claimed. I bought a bxi1206 to run a volfenhag 4812 & it hits incredibly hard. I definitely would go for a single 12" or 2 10". I have a custom fabrication setup , but can tell you there is no way I could have made sufficient air space to fit 2 of the 12's I put in. I paid $1100 for everything I have. https://www.rx8club.com/series-i-interior-audio-electronics-24/showing-off-my-sound-112979/ if you want to see everything. Keep in mind that like $150 is needed for an LOC, which takes a chunk out of your budget, so a single 12" is a good option to save a little. It is way more than this car needs anyway.

1) as little as I can without sacrificing power
2) a bit of both, I guess SPL would be more what I am going for
3) no, I want this to be a one shot deal
4) good equipment
5) guess... no im kiddin, educated

Also, what is a "ported" box?

Thanks for all the info. If you were in my position, and wanted to spend under $1000, what exactly would you buy? Also keep in mind like $150 of it comes out for having this guy build the box and wire everything for me. So for $850, what exactly would you buy? Thanks!

A ported box allows the back pressure wave of the speaker to reinforce the front pressure wave of the speaker. A speaker makes sound on both the outward stroke and on the inward stroke. A port allows this inward pressure wave to escape and makes the system play that much louder again.

Want loud, all things being equal, two 10's are louder than one 12. However, things are not always equal. One single 12" high output sub like the DD2512 will obliterate most other 10" drivers that are not in the same class. Give it 500-800w rms of power and it will absolutely thunder in your car. One single driver in the proper box is going to take up less real estate in your trunk as compared to two 10" drivers in their box. A 8" sub can and will play the exact same deep bass note as a 15" does, it just cannot do it with the same amplitude due to restrictions based on the mechanical abilities of the sub.

You do not need 2000watts of power to get loud. 300 watts of power is even more than enough to get loud. 20 years ago power like we have now was unheard of, yes things could indeed still get loud. It is all in how it is matched together. Choose the right sub, the proper box for it, power it properly, interface and install it into your vehicle properly and you will have a highly predictable outcome.

Based on what you have mentioned, I would look at the following.

1 - Digital Designs DD2512
1 - custom slot port box
1 - amplifier wiring kit, 4 gauge
1 - BIG 3 wiring upgrade (can be done in the future)
1 - mono subwoofer amplifier designed and engineered to operate at 2 ohms and provide between 500 - 800w rms into 2 ohms. The Pioneer Premiere PRSD1000M amp comes to mind right now, many other to choose from as well.

Just be sure that your sub is made for a ported box before you go that route. Some are made for enclosed, some for ported, & some of them can use bandpass boxes. Bandpass always sound great to me, but not sure if you have enough room in the trunk for one of these, no matter what size you go with (you'd have to check).

ricky356

since your budget is tight you just may have to go with the single 12" sub. in that case i would go with what forbidden sugested. the digital designs subs are out standing and i know they can be pricey as well but i think the dd2512 should fit your budget. i know a 35 series 10" runs about $480 ....or so i was told and the 9100 series is almost $1000 for a ten inch sub.if you can save up and get two tens i would do that. but with the money your workin with i would just go with a nice twelve inch sub. not saying that you couldnt find two tens for the price of that 12 .............but would they be able to handle all that power? so the hifonics bxi2607d amp and the digital designs dd2512. by the way digital designs holds the spl world record for a single sub setup.

good luck
