Long time member of the forums, but haven't been around in a few years. I was devoting most of my time to getting my CarPC where I wanted in terms of features and SQL. Now that I have it sorted out, I'm looking to do a bit of upgrading in my audio hardware department.

Right now I'm running Infinity 5000cs 5.25" comps up front, with 2 Pioneer 305DVC's in the trunk. While it sounds pretty good, I'm really having to stretch my subs out to match up with the 5.25" drivers in the front. Using a cut crossover of 110Hz at the moment and would like to get that down to around 90Hz or 100Hz at the highest.

Keep in mind that I am budget limited on this at no more than $200.00 for the component set. Whether I end up going 5.25" or moving up to 6.5" this is an absolute hard limit for my cash flow.

Couple of questions now. Can I realistically find a set of 5.25" comps that will get me to my goal of 90Hz realistically? I listen to the music fairly loud so keep this in mind. If this is not feasible, I can go to 6.5" components.

Another question, is it worth it to even upgrade at this point? For under $200.00 will I notice a fairly large difference over what I'm using now? Basically is it even worth buying new equipment with my limited budget or should I just stick to what I have?

Thanks in advance for any help, it's much appreciated.

Wow, just was looking around and noticed many people using the PG RSd 65cs comp set. Seems like it has mucho respect around here and it can be had for around $100.00 on Ebay and various other sites. This would seem to be my best option as of now. Discuss.... :D

don't expect much down low from any 5 1/4" speakers. and yea the rsd65cs's are pretty darn good and inexpensive.

I see this, like $87.00 shipped for the 6.5" set. Man, only thing is, I don't know if I can fit the 6.5" drivers into my existing mount. Not sure if its deep enough. I'm driving a '99 Regal right now that had 5.25" installed factory. Guess I'll have to check this coming weekend if we can fab up a new MDF ring and get them in.

Wish me luck, if it fits, I'll definitely be purchasing a set of these before they go out of stock everywhere.

cool. if they fit then try them. they are 2.87 inches deep though, so ya gotta watch out for depth as well as width.

He's right, the basket width can bite you in the *** too depending on the car.

Thanks for the measurements, I'll do some mock up work this weekend and see how things go. In all honesty, I should just order them and then if they don't fit I'm sure some one would be willing to buy them off me.

I would do the measurements first, but I just don't have much time for install, fabrication as of late. Would be much better with components in hand first.

do whatever ya gotta do. honestly though i think you might have a hard time selling them used when you can get them brand new in the box for so cheap.

I see you're running your PG RSD's active. That's exactly what I plan on doing. I noticed that the frequency response is excellent on the drivers. What is your current cross over point for the RSD's and do you think they will fill in my 80Hz to 100Hz gap effectively?

in sealed and deadened doors they will drop down pretty low. right now because i have so much power going to them i have the crossover at 80hz with a 12db slope. a while back i had them playing down to 50hz using a 24db slope. they played pretty well down to 50hz as long as you don't crank the sh*t out of them. a normal 6.5" woofer should be crossed around 80hz if you want to get any good volume out of the set w/o distortion. this set does have excellent output on the bottom end. with a lot of power, crossed at 80hz they do great.

they are a great set to get if you need to run passive for a while but would like to try active in the future. but running them active can do wonders for them.
