Ok, so I'm starting to get my system all set up in my tC now and I'm looking for some suggestions. I have a couple ideas on what I want to do but I'm worried about how it will sound. My ultimate goal for my system is to get it as loud as possible while still having good sound quality throughout the vehicle. I'd prefer not to just load up on the front speakers like competitors do. Here's the equipment I have currently.

Deck: Alpine CDA-9856
Speakers: Keeping Stock for the Moment
Amplifier: RockfordFosgate Power T4004
Subs: 2 12" Duals in Ported Box (Best Buy special)
Sub Amp: JL Audio e1400D

I could put in Alpine Type-S speakers for now, but I think the stock speakers will be fine until I upgrade. Here's what I was planning. I was thinking I'd upgrade the speakers to Apline Type-X components and I'd get a set of Element Designs Eu-650s. I was going to put 1 set of components in the front and 1 set in the trunk angled at the rear window and the Eu-650s in where the stock rear speakers are. I'm pretty sure my amp will be able to power the Eu-650s and the rear components but I've been wrong before. I'm concerned that the Eu-650s will be too overpowering if I put them where the stock rear speakers are but I'm not sure. One of the reasons I want components in the way back is so that when I open the hatch music, and not bass, comes out. I want my car to be a boombox on wheels, so when I open the doors and the hatch I want it to sound good but at the same time I want it to sound good on the inside.

I'm also open to any suggestions in regards to speakers. The Type-Xs are running about $220 a set and the Eu-650s are $85.00 a set. My amp can put out a lot of power so I want to use it, but I don't want to sacrifice sound quality to get it. For speakers I'm looking to spend under $600.

Note: Here's the power ratings for a quick reference. The amp rating is "Actual (Rated)"
RockfordFosgate Power T4004 - 90 x 4 @ 4 ohms (25 x 4 @ 4 ohms); 151 x 4 @ 1 ohm (100 x 4 @ 1 ohm)
Alpine SPX-177R - 75 watts
Eu-650 - 150 watts

 

1) Sell the Duals...
2) shop at www.edesignaudio.com for everything you need... all their products are top notch and inexpensive!!

the eDi6500s components are only $250 and would be comparable to the type-x's, The 6500s vs. JL XR comps both in a tC, the 6500s win hands down, better bass response and more natural tweets...

Don't overload your car with mids and highs.. that=bad imaging/staging... if you REALLY want rears, get good components up front (eDi6500s) with a mid in the rear speaker spot (Eu-650) of equal type...

 

Replacing the subs is kind of low on my list for the moment. They're 600watts and it was only like $150. I thought I'd blow em and get new ones but it hasn't happened yet and they actually sound pretty good.

I don't quite get the overloading. It would still have 4 speakers and all I'm doing is adding the mid-bass.

 

the main reason many competitors in SQ only have front speakers is for imaging and staging. CD's, MP3's, radio, etc are all "stereo" recordings. Stereo=2channel (front left, front right)... 2 channels is all that is needed for accurate reproduction of the original recording and that is exactly what SQ is about, accuracy.

it's all in personal preference but I know I'll never have any sort of upgraded rear speakers in any car i ever own.. only fronts...
