Hey so I've only been having this issue since I switched out my subs and amplifier from a kenwood excelon set up to the rockford amp and subs. Whats happening is the amp BANGS all day no matter what at the lows but the moment it gets to a higher frequency seems like a punchier frequency (I wish i Knew what frequency it was but i Just know its not the low end probably way closer to 80hz), it goes into PROTECTION mode. I thought at first it wasn't getting enough voltage and my battery tested at 50% cause i do have a battery tester at our shop, so I changed my battery today and I'm still having the same issue. I know its not my wiring because i had no problems with others amps and subs ect. Rockfords support tech keeps saying its clipping at this certain frequency, which I'm not eliminating yet, but the thing is I have my gain set to just under 7, and it was still doing the same thing even when i had the gain set to under 5. and it doesnt hit nearly as hard as it should be unless i turn the gain closer to over half. I just want to know what i can eliminate and what i should try if you guys are familiar with this issue. If my amp is clipping why wouldnt it be clipping on the lows and only does it on the highs? Another thing is it hardly does it when I'm parked, mailny does it when I'm driving which is really irritating because I want it when I'm driving I could care less about being parked as this is just my daily driver. Any advice would help. The other 3 installers at my shop said battery and rockford only said clipping.. I also tested my alternator with our snap on tester and it also tested good. All that rockford said was too turn down the gain but I know those subs can handle what I'm giving them at least I would think.. Radio is outputting full 5.0 volts
Gain = ~60%
Lpf = ~25%
Punch EQ = 0
subsonic filter = 50%
2005 Dodge Stratus

whats up fam. so heres a quick run down of my system. not a trunk build, not a wall, just a simple ugly back seat build lol i am a construction electrician with my trunk almost always full with tools and material for work. only other spot to fit a sub box with out doing a wall is my back seat. i just need some bass! not really going for looks. ive had some pictures on what i had before (just went from a skar evl15 to a dc xl15 and sae1500 to a dc 2k) so here are some recent pics... hope you guys enjoy...
i personally did the big3 with sky high 1/0 up front and ran power from front stock battery to rear full throttle group 34. messed up by getting a blue big 3 kit instead of red lol oh well.
heres what it looked like before i swapped out the sae1500. the rest of the wiring was done by arden audio in sacramento. when i went home and did a lil inspection i have noticed the ground going to the 4ch amp was just self tapped in with 3 screws on the frame of the vehicle. wasnt too happy about it so instead of complaining i just went ahead and fixed it. both grounds are now sharing an existing grounding point directly under the driver seat. everything else was fine, thanks arden audio!
and heres the box just sitting on the back seat haha
I have some questions about setting up my system.
So far it consists of:
2008 Chevy Trailblazer LS
Rockford Fosgate 3Sixty.3
Rockford Fosgate P1000-1bd (2007/2008)
Rockford Fosgate PEQ Knob for Bass
Rockford Fosgate P500-4 (2007/2008)
Rockford Fosgate Punch Pro PPS4-6
Rockford Fosgate Punch P1T-S
2x Kenwood KFC-W3009
Rockford Fosgate 0 Gauge Amp Kit
Sky High Car Audio Speaker Wire
I'm going to be using the 360.3 for active crossovers instead of the passive ones that came with the P1T-S.
I'm using 2 channels of the 500-4 for the 6.5" and the other 2 channels for the tweeters in the dash. I'm gonna change that once I get a Punch 200-2. Then I will use the 2 channels that were used for the tweeters to power two rear speakers and use the 200-2 for the tweeters.
The first thing I'm wondering is: if it's okay to run the 2 RJ-45 cables used to control the 360.3 and the PEQ next to the speaker wires and RCA cables along the right side of the car. Will this cause any noise in either the speaker wires or RCA cables, or even in the RJ-45 cable?
Second question is: what's the best way to ensure that I'm not feeding too much power to the tweeters? They are capable of 60 Watts RMS but my amp is able to do up to 125 Watts RMS. How do I keep the Watts down to keep from blowing them?
