These JL speakers work with 300/4 amp?

[seeitgo]

Oh okay, does it seem that the C2-650 external crossovers would work well with JL 300/4 amp?

OR better yet

which would you choose? haha!

the TR set is older, i think. there's no external crossover so there's probably just a cap on the tweeter and no lowpass for the mid. the CS set has a better crossover so they'll probably sound better...

the crossovers will work with any amp, since they're designed to protect the speakers.

run the highpass (HPF) on the amp at about 80Hz.

I will try that, thanks!

By the way, I have purchased the JL C2-650

The JL C2-650 Component specs say
Peak Power: 200 watts per pair / 100 watts each
RMS Power: 120 watts per pair / 60 watts each

Should I just use 2 channels from the JL 300/4 amp, so 75W each
-OR-
Can I bridge the amp and give 150W each?

if you're going to overpower them, make sure the highpass is set (and set correctly) and be positive about your gain setting with relation to maximum volume on the headunit.

the only ways to smoke speakers is by playing them outside their intended passbands for too long, or by overpowering them--both of which equal overheating the coil. if you're careful and have common sense, it's not an issue to do it.

I'm still here!! I'm just quiet. I can make the rings and I do have some other material to make them out of but it is very tough to work with and the best way I've found to cut them is a simple ring with my router. I tried to make a set from the material for my Fit and I burnt up two blades and spent an hour cutting one ring with a jig saw. I haven't posted anything about them since I put them in the Fit about 4 months ago and waiting to see how they hold up. If they hold up like I expect I'll start making them from the new material. I will admit that this stuff is expensive so the current price will have to go up to recoup some of the cost. They might not work well in a 6th gen since the door metal is stamped with so many ridges.

I have made them before and coated them in fiberglass resin and that usually helps but it adds time to the process.

Feel free to email me at [email protected] or PM me on here and I'll answer any questions that you might have.

That new material looks like it will hold up really well! I will definitely message you once i get my speakers and start installing.

I'm pretty sure i will finally get to understanding the need for spacers as ryan_s has been describing and a need for a bracket like yours.

Thanks for all the support and willing to help me out guys! I'm just waiting for my speakers to arrive through FedEx in the next 3 days.

I have been unable to figure out the following:
Questions:
what kind of RCA's I need
-&-
how to wire them.

I see RCA's online that have:
(1) input and (2) output
-or-
(2) input and (2) output
etc.

So, I will have a JL 300/4 amp powering my components in the front
&
a 500/1 powering my sub in the trunk.
&
My rears will either be removed or be powered by my HU

My headunit has RCA female outputs of:
- (R) Audio IN
- (L) Audio IN
- Front (R) speaker OUT
- Rear (R) speaker OUT
- Front (L) speaker OUT
- Rear (L) speaker OUT
- Video OUT
- Video IN
- Subwoofer Line OUT

Thanks for any explanations on how to wire this part of my audio system.

Pictures would be really helpful too

You've got a few options. The easiest is to buy three sets of stereo RCA's (two in/two out). This way you can run a front pair/rear pair and sub pair. Even though you don't need but one rca for the mono amp having a pair may be helpful in the future. Once it comes to the install you should run all three pairs and match them to where they go - Front RCA output to the Front input of the 300/4. Rear output to the Rear input of the 300/4. Sub output to the input of the 500/1. You will have front to rear fade and sub control from the radio. The next obstacle is the gain structure for each amp. You can do some research or use the JL tutorial on their website. That way will get you close to the ideal input to the amp. You just need a few special discs and some sense, and a little time.

You can buy a four conductor RCA for the front/rear but you might run into issues in the future if you have a cable issue.

Good luck and make sure you spend some time on the install and do it right the first time.
