i am currently running alpine type r fronts and rears along with type r 12" sub powered by alpine pdx 1.6 and 4.1 amps. i hear a lot of high end systems don't run rear speakers and a lot of people recommend removing them. i am just wondering if i should also remove my rear speakers? also, would road noise be an issue having the rears removed?

 

True. The only folks who consistently install speakers in the rear shelf are those on automotive forums.

If you want better sound quality, sure. Bridge the amp and send full power to the fronts.

I'm not sure I understand. Removing the speakers from the rear shelf will help to vent the sub into the cabin, albeit slightly. Bass has no trouble traveling through the back seat.

thanks a lot for you reply and i' sorry for not clarifying: i've read on some other car forum (sorry i forgot which) that people are getting a lot more road noise from removing the rears. is it the same with our cars too?

 

Ahh...I see what you're saying. I can't say that I noticed any change in the noise floor. Our cars are so loud as it is, that if there were a change, it would just blend in with the rest of the noise.

When I started working on a system for the Evo, I used the same rationale as in any other car. The system sounded great when the car wasn't turned on, but as soon as it started moving, everything fell apart. Getting good sound in an Evo was easily the most challenging audio project I've done. This is coming from a guy who built a (48ft3) mass-loaded transmission line sub into his house. I guess I'm trying to say that the challenges of the environment override most commonly accepted tuning techniques.

Edit: As you're one of the few folks who genuinely seems interested in improving his system, I should say a bit more. Have you considered upgrading your equipment? I don't mean necessarily spending more cash. CA.com has a thriving FS board where Type-Rs sell well mostly to new folks. You could sell both pairs of speakers and the sub, and then use the funds to purchase gear more better-suited for the car. I can tell you that I personally tested 8 different drivers and 5 enclosures in the Evo before arriving at a point where the bass wasn't ****. I may have missed it, which HU are you running?

 

i'm running on a pioneer avic n4 headunit. what speakers would you recommend me upgrading to?

 

Apologies for the belated reply. I unsubscribed from a bunch of threads the other day, and I guess this one, too, by mistake.

IIRC, the Pioneer features a 3-band PEQ as its sole tuning option, is that correct?

It's difficult to make specific speaker recommendations, without knowing more about one's tastes and preferences. From a purely functional standpoint, you need speakers that don't require extensive tuning. The only ones that I can think of are Boston Pros.

Sub-wise, it's much easier to point to a specific driver/enclosure combo. This is hardly the most exotic setup, but it fits the application extremely well. The sub is VERY sensitive and its in-Evo FR is -/+3dB from 40-80Hz (amazing in itself). It sounds tight, articulated and defined. A night and day difference next to a Type-R:

This combo replaced an IDQ12V2 that stood as a reference for 4 years.
