[QUOTE="R2D2, post: 8685517, member: 678145"] Long story short I replaced old alpine e12 sub and a dhd amp I bought 10+ yrs ago and I got the 2 items below. I got the sub first but I am thinking it wasn't strong enough to handle the amp or I just put 2 much power into it, but my settings were not that high ( or so I believe) so I am not sure if it could be some thing else. Its hooked up to a stock 2001 gs300 radio system and I control the bass with PAC bass knob and have it wired to a kicker L.O.C. in the rear stock sub.. my old system was fine up until last month when the e12 died of natural causes lol. So here are the questions: Did I use too much power? Did I pair sub and amp incorrectly? Improper Tuning? Improper Wiring of Sub? ..ALL OF THE ABOVE.. SKAR AUDIO IX-12 D4 [ATTACH type="full" alt="18986"]18986[/ATTACH] Sub was wired like this [ATTACH type="full" alt="18988"]18988[/ATTACH] Technical Specifications Skar Audio IX-12 D4 Dual 4 Ohm Voice Coil Configuration Peak Power: 500 Watts RMS Power: 250 Watts Pressed Paper Cone Advanced Air Flow Cooling System 2" BASV High Temperature Copper Voice Coil Motor Weight: 40 oz Frequency Response: 25 - 300 Hz Sensitivity: 88.1 dB ALPINE MRV -M500 [ATTACH type="full" alt="18987"]18987[/ATTACH] [COLOR=rgb(44, 130, 201)][B] [/B][FONT=verdana][B]Gain was set at the notch below 1/2, lpf to 80, and bass eq to +3[/B][/FONT][/COLOR] Performance RMS Power Output (Watts x Channels) 300 x 1 Peak Power Output (Watts x Channels) N/A Power at 2 Ohms (Watts x Channels) 500 x 1 Bridged Power (Watts x Channels) N/A Minimum Impedance Bridged N/A Minimum Impedance Unbridged 2 Best Frequency Response 7-400 Hz THD at Rated RMS Power 0.2% Signal to Noise Ratio 85 dB Input Voltage 14.4v Features Amplifier Class D Low-Pass Crossover Frequency 50-400 Hz Low-Pass Slope (dB/octave) 24 dB/octave High-Pass Crossover Frequency N/A High-Pass Slope (dB/octave) N/A Bass Boost 0-12 dB Bass Boost Frequency 50 Hz Fan Cooled No Fuse Rating 60 [/QUOTE]
