If the amp takes high level inputs, then under the hood it's the same thing as a line out converter
The overlap in filtered/unfiltered frequency range will be hard on the amplifier since it will be driving both in parallel. Otherwise it might sound fine, you could drop the midrange to compensate a little.fusseli - I have a pair of JL C2-350x and Alpine SPE 6090 I plan to install in my 6 speaker setup. I also have some SPR-60c components from my last car. Reading through your install makes me wonder - would you think I could run the SPE6090 in the rear, and use the woofer from my Alpine component speakers in the door? They have a LPF - the inductor reads 0.20mH and from quick reading I'm guessing this would be around 3200hz, would there be too much overlap in frequencies from the full range in the dash?
Previously I had a WJ Grand Cherokee with the components installed in the front - tweeters dash and woofers door, howver there was definitely a noticeable gap between sound. This car has a good sound stage although abysmal speakers - I'd like to keep the stage as close to stock as possible while upgrading the quality of the speakers and am wondering if the overlap would hurt or help.
I'm in the same boat right now; I want to upgrade my factory speakers (6 speaker option) but am having a heck of a time finding quality 3.5" 8-ohm dash speakers.TLDR: Upgraded all speakers now the dash is too loud/bright/harsh. Bass +4, mid +0, treb -2, fade to rear -3. Need help lowering dash speaker volume.
I've installed the dash speakers first since they arrived first. I noticed it sounds great as long as I keep the volume under 13. Anything over and it's too loud and piercing. Overpowers the door speakers. Gets worse as volume increases. Adjusting treble doesn't help. Ended with Bass +4, mid +0, treb -2, fade to rear -3 but still ear piercing and lost midbass up front.
A few days later I installed the Alpines in all 4 doors and although the Alpines sound great, the dash is still too loud and overpowering.
I tried reversing the polarities on both dash speakers but did not help. I think reversing the polarities may have made it a little worse and sounds distorted at 15+ volume.
I then tried without any dash speakers and just the Alpines in the doors. I didn't like sound, and would prefer completely stock compared to this.
At the moment I have the stock dash speakers with the Alpines in the door. Overall It's better than stock, but I would like to improve it without too much work if possible.
I feel like if the volume on the dash can be controlled independently, this would solve my problem.
The pioneer dash speakers are 4 ohm, while the stock are 8 ohm. Is this playing a big part in the volume? I notice as I increase the volume, the Dash's volume increase exponentially with the pioneers, does this make sense? I'm willing to purchase 8 ohm speakers, I could not find any though. Is there something I could add to the dash speakers? I've read resistors can mess up the sound and could add peaks and dips.
Out of curiosity, how would this have any sort of negative effect on the radio?FCA got around this harshness by using 8-ohm speakers in the dash to attenuate the sound relative to the door speakers. Now, one option is to use 4-ohm speakers in the dash and 2-ohm speakers in the door (same ratio as factory), but now we're HALVING the effective resistance that the radio "sees". Yes, it'll put out TWICE the power (assuming perfect amplification, which isn't happening in a stock head unit!), or the same sound intensity at half the Volume Level, but is that SAFE for the radio? I have a Lifetime Maxcare warranty and don't want to void the radio warranty due to installing low-impedance speakers.
I sent an email to Panasonic asking about this. Let’s see if they respond at all.The lower the speaker resistance, the more power the radio will try to put out. I have no idea what the minimum speaker resistance rating for the radio is though, nor do I know if the radio has "too low resistance" protection circuitry. If you get too low, it's basically the same as a "dead short" and electronics inside the radio will overheat and become damaged.
Yeah. It's made by Panasonic. If they respond I'll see what info I can get.Panasonic? Do they make the 8.4 radios for Jeep? I dunno - never pulled the head unit to look for a manufacturer label.
The question would need to be posed to the manufacturer of the head unit; ask them what is the minimum speaker impedance that the head unit is rated for.
I sent requests to both FCA and Panasonic.Yeah. It's made by Panasonic. If they respond I'll see what info I can get.
