Aftermarket Speaker Fit Questions

**Scorpx** · 10-26-2004, 03:01 PM

I was wondering what size speakers the auio guys in the forum have been using. I am upgrading and am debating between just replacing the fronts with 6x9's or going component speakers. If I go component should I use 5 1/4's(which will require a fabricated piece) or will 6 1/2s fit without cutting? I have not pulled the panels off yet to see what type of mounts are there. Any advice will help. I want to do as little modification as possible so if I get rid of the car in a few years I can DROP the factory stuff back in easily.

well I haven't actualy replaced the speakers in mine yet, but I will be going with 6 1/2" component speakers, they will fit in a 6x9 opening, you just need an adaptor plate, crutchfield sells pre-made ones if you don't feel like making them yourself too

Well since Scorpx seems to have an SXT he may well have the non-Boston audio system. That has 6-1/2" speakers in the doors.
It would be silly to REPLACE those with nasty 6x9 speakers. Upgrade to proper 6-1/2" round speakers - they will sound much better. Use good quality pieces like MB Quart or Focal.

All the documentation says that all the speaker packages have 6x9's in the doors FROM the basic 4 speaker package all the way up to the 6 speaker package in the 300. Where did you read that the SXT has 6.5" speakers?

There were some non-Boston systems that came with 6-1/2" speakers in the doors.

I have seen both. There are even web sites with photos of 6-1/2" speakers in the doors. Do a search for it and you'll see.

The service manual says that there are 6x9 speakers in the front doors for all models so that may be the case with current cars.

Hmm, I pulled those sizes FROM TechAuthority... I'm not saying your wrong, I haven't seen one myself so maybe DC changed it after they published their documentation.

i've seen one person who had the 4 speaker setup say he had either 6 1/2 or 6 3/4 (forget which off hand) in the front when he changed his speakers, he had posted pictures of it too, looked like it had a 6x9 hole but with an odd looking plastic adaptor that he said was on there FROM the factory, it did look like a factory part not an aftermarket adaptor plate.

Huh, weird that they would have done that. Must have had a shortage of the 6x9's or a surplus of 6.5" that they wanted rid of... Cool, thanks for setting me straight guys.

There are cars with 6-1/2" speakers in the front doors. I saw them myself yesterday. (They were base 300's) And I did see photographs of an SXT Magnum with the base stereo with 6-1/2" speakers in the doors a few months ago.

However I can verify that the elisive animal known as 6-1/2" speaker does exist.

In any case, whatever is there should be replaced with a high quality 6-1/2" speaker. 6x9s don't cut it in the sound quality department so if they are there to begin with you should buy or make an adapter plate and install a proper 6-1/2" speaker.

I had 6-1/2's in the front doors of my magnum. I replaced them with Precision Power 6-1/2's and they sound great. I used the factory plate that fit the 6-1/2 in the 6x9 hole and just trimmed the inside enough to let the new 6-1/2 sit flat.

I have been designing and making speakers for over 20 years. If designed equally well, the 6x 9 should have better bass and also be a little louder since it has more surface area. The key is in the design. I was Chief Engineer at Jensen speakers , then head of engineering at Onkyo speakers until starting my own small speaker company here in Indiana called SEI (Sound Enginering Inc,)

We make custom speakers where you tell us what you want and we will build it for you.
American designed and made...Even make custom dust dap logo's.
Can't wait to get a Magnum SRT-8 for a company car and do a great system.
Saw some cool systems at CES in Vegas.

How would the pricing of your custom hand designed and manufactured speakers compare to existing commercially available products? Is it at all feasable for you to compete or are we looking at a niche market here?

**Rev.Hammer** · 01-17-2005, 12:06 PM

Sooo what are we talking $-wise there Ssmith?

**ssmith47201** · 01-17-2005, 09:56 PM

Our prices are about the same or maybe less since there is no middle man. We have been involved throughout our career in designiing/manufacturing both OEM and aftermaket customers. We are a GROUP of 8 FROM engineering and manufacturing backgrounds that have worked for Jensen, Harmon and Onkyo. Our average experience is over 8 years. I was a speaker Engineer at Jensen and left as Chief Engineer 15 years later to lead the engineering GROUP at Onkyo here in Indiana. After a change in ownership, we formed our small company and bought Onkyo equipment and inventory of parts.

We have dsigned / manufactured for AR, Advent, Acura, Chrysler, Eclipse, Ford, GM, Hammond Organ,Honda, JBL, JL Audio, Jensen, Nissan, Mitsubishi, Phase Linear, Rockford-Fosgate, Toyota and Others

We can build or REPAIR almost anything you want ...I can also provide before and after acoustical measurements if you send me a OEM driver.
Guess I should CHECK INTO becoming an official vendor

I wish I had a Magnum to CHECK out for you. I may do some quick research to see what I can find that will fit. Is there any way for you to tell how much more room you have beyond the OEM driver. If you decide to stay with a 6x9, I'll measure the old one for you, design something better and SHOW you the difference. 50% discount given to the first person to send an old one, since it will assist me in designing a better one that can be offeredto all Magnum owners.

I can also design a 6.5 to beat the 6 x 9 too.
