Had my T1 Wired for 1Ω. Kept my gain set between 1/3 and 1/2, Bass Boost off, Low Pass at roughly 85-110hz, sub-sonic filter (if available) set at 25-30hz (estimates based on range of motion of the dials.)
My DEH-2200UB has a Sound Retrieve feature for digital files, (I've used a USB Flash Drive for my music since I installed this Head-unit.) I've used S. Ret. on level 2 because it brings back rich highs and deep lows. EQ on Custom with 0 Treble, 0 Mid, 0 Bass, SLA set on 0. (Each setting goes +/-6, except SLA which is +/-4)
Stock alt/power wires for '98 Grand Prix GTP (Not sure of the Alts amperage.) Duralast Yellow Top Battery.
(Not sure of brand) 4-Gauge Power/Ground, 60 Amp AGU Fuse within 6 inches of the power connection under my hood, Kicker Shielded RCA's, 18-Gauge Blue Remote wire.
So far my T1 ate through an Audiobahn A1300-HCT(Which lasted 6-9months with my T1 until Sunday evening,) and a Kole Audio KX1-2000D (Which only lasted two days.)
Took my sub to a local shop and was told I have a Bad Voice Coil on my T1 (Which has caused the amps to blow) and no audio output on both amps, but they appear to be taking power.
Asked them to leave my sub out of the box (was in a box when I brought it to them.)
Arriving home I break out my handy-dandy Multi-Meter to read the coils for myself.
*Side note, I'm missing the plastic trim piece that surrounds the woofer facade. Plus my genius friend used elastometric sealant around the edges of the subwoofer once upon a time, haven't felt any leaks so haven't cleaned it off.
According to specs from SonicElectronix, the voice coils should read 2.0Ω each.
Help is GREATLY appreciated, Criticism is welcome. Flaming is just plain mean.
