Need help for a system in an Evo 8...

[TwStDeVo 0]

hi,

im new to the forum and been looking through countless threads but cant come up with the best set up for myself. i would really appreciate everyone's help! i already got a system in my car but im not happy with the bass output (plus the subs are overpowered and keep going out). i mostly listen to rap/hip hop and want to be as loud as possible. currently, im running 2 boston acoustic g5 12s and 2 12" radiators off of a mtx 1501d. the enclosure is a custom install in my spare tire well which gives the 2 12s 1cf each, the radiators are separate. im thinking about replacing the 2 12s and the radiators with just 2 Q series 12s and i see that 1cf is enough but 1.3 is recommended, so i was thinking about adding some polyfill to get the extra airspace. would this set up be loud?

if not, last option is to remove my rear strut bar and have a new box with the sub/s (ported if needed) facing the rear of the car (only if it would be a big enough difference from the spare tire location). i dont want to lose all of my trunk space but i am willing to lose some if it will be worth it. if i change my set up to this way (which i most likely will) im thinking about doing 1 12" Q ported, 2 12" Q's sealed, 1 12" BL Ported, or 1 15" Q sealed. what would be the best and loudest option(1500watt amp)? Looking for loud, clean, deep hard hitting bass! here is what my trunk looks like, there is about 35inches between the wheel wells and about 13-15inches in height.

What's the rest of the "system"?

eclipse 5510 deck, focal polyglass 6.5 components (thinking about replacing with cdt es-62i gold), focal 6.5 coaxals in the rear (going to remove), eclipse amp for mids (200watts), mini battery up front (so i can clear my upper intercooler pipe), optima extended yellow top in trunk (larger size battery), 1 farad cap, and i will soon be installing an irragi 180amp alternator.

still looking for help, thinking about going 1 15 q or bl ported.

Hmmm... I wouldnt want to remove the strut brace at all. No reason to add some chassis flex for a sub box. If you were local I could fab a new one that integrates with an enclosure (I used to do chassis fab for road race cars).

1500W is definitley on the high side of things for a single Q. Im sure others will tell you different though (I stick closer to our ratings with most recommendations). A pair of 12s would be louder than a single 15 (when in like enclosures). Maybe a pair of SSDs off that amp? Do the seats drop down too?

Qs would work fine sealed in 1 cuft. You could always stuff with up to 1lb of poly fill to gain up to about 15% in percieved box volume.

Thanks,

Scott

thanks scott, ive been anxiously waiting for a reply from you. i can definitely remove the rear strut brace as ive spoke with numerous autocross racers and suspension guys and they said in most cars the rear strut bar helps alot but in my car the way the suspension is set up there is not real difference. also, seats do not drop down.

now for the subs set up:

1) would it make a big enough difference to change the way the subs face from up to firing back?

2) how would 2 12s (Q) sealed compare to 1 12 ported?

3) what about 2 10s ported, would you recommend that over others (2 12s sealed)?

4) whats the best enclosure for 2 ssd 12s ported?

5) what would be an optimal box for the type of music i listen to (rap/hip hop) for 2 10s ported ? 1 12 ported? 1 15 ported? all of them q or bl series. ive seen 2.2cf tuned to 32hz for 1 12 and 3.5 cf tuned to 32hz for 1 15, not sure about 10s.

6) would 2 12 q (or bl is possible) sealed be alot louder than my 2 12 boston g5?

if you have further ideas, please post as im looking for a custom set up that does not take up the whole trunk but i can sacrifice a little past the wheel well arches. if it does not make a big enough difference changing the way the subs face, then i will keep the same set up. appreciate your help and looking to place an order as soon as you can let me know the best set up for my car.

bump! i decided to change my current set up with the boston subs next week. right now its 2 10" bl or icons ported. would this be better than say 1 12 ported or 1 15 ported if it can fit in my available space? also trying to decide how to do my trunk, want to make it look really custom but not sacrifice sound. so far its either facing the sub/s back or towards the cabin. between the trunk and the car there is just a metal cross brace. appreciate everyone's help as i need to finalize everything as soon as possible!
