SQ setup in my car
 

Okay everyone

I have narrowed down the following list of equipment to be used in my new car for an SQ setup:

1. Alpine 9887 HU
2. Polk's SR6500 components (no rear fill)
3. Polk SR124 sub

I need the following from the experts please:
1. What amp setup should I follow? I was thinking on getting a 2 way Polk Momo for the fronts and the monoblock for the sub or maybe the 400.4 MOMO for the fronts and two channels bridged for the sub...any better options than this without using a lot more money (maybe upto 200$ in price difference versus what I am looking at for amps versus the 400.4 setup)
2. Anything (HU or sub or components) you would want to change in favour of better SQ with not more than $300 additional spent on the setup? (I have an option of getting the Premium series MB Quarts installed as well)
3. Ideas/pointers/advice on installation? (My car is a 2006 Honda Accord). I really need the setup to shine through in SQ

My current small car has a pioneer 880PRS HU and MB Quart Reference front components with Punch series Rockford Fosgate amp and sub (10"). What I am looking at is a 'significant' increase in SQ. There was no special installation done on the 1000 cc car I had except the tweeters which were mounted on the A pillars and sub was in an infinite baffle config.

Take care

How about sound deadener?

Can you post some photos of your install?

You already have a great base to work from, especially the 880PRS. I bet a "significant" improvement in SQ could be achieved with install improvements and tuning.

I am looking at sound deadening, although do not have any clue of how to do it properly in my accord. One more thing that is bothering me is the change in SQ my HU will bring versus the 880 prs. Will it be noticeable? what about the speakers, should i go with the MB quarts premiums or the polks?

Also looking at suggestions for the amp(s) please

Worry less about components and more about install. Speaker position is going to have a way greater effect on SQ than anything else.

Can you explain a little more? the speakers (6.5" woofers in the front) will be mounted in the door panels in the standard location, whereas I am thinking of mounting the tweeters on the A pillars...any suggestions to better this?

Tweeters in the A pillar is a good plan. If you can get tweeters that handle a lower crossover point that will help bring the sound stage up higher.

switching 880 for alpine deck will not introduce any dramatic effects on your sq. save your money and spend it on deadening and proper install.

I use auto ta and eq with the 880prs, and I like it very much (never tuned an HU myself and no tuners here). Is the imprint calibration result better in SQ than the 880prs auto ta and eq?
Would also like to ask if any of you has any comments on the kenwood kdc-x991 (especially what about the auto ta and eq...does it have them?)

Thanks

I don't know much about the imprint system, but I think you won't get a dramatic gain in quality from swapping headunits. Deaden the heck out of your car, work a lot with your speaker positioning. Try out different placements for your tweeters, different aiming, and find what's best. If you can angle your mids towards you rather than facing each other, that might help out with staging too.

I just did a small adjustment to my kickpanels (about 10~15 degrees to the orientation of the speaker) this weekend and the stage went up about 6 inches and the depth increased a lot. When listening to Sara K.'s If I could sing your blues, the trumpet sounds really far in the back.
