S1R-BLUNTZWORTH Posted August 22, 2008 Report Posted August 22, 2008 I have ordered a new amp to replace my T8002. The new amp is a T1500-1bd, and supposedly does 1500wrms @ 1 ohm. With my current speakers (2 12" mtx 8500's, rated @ 500w RMS each) i only have a choice of wiring the subs at 1 ohm or 4 ohms because they are both dual voice coil 4ohm subs. So.... If I wire them @ 4ohms, I only get 500wrms x1 out of the amp, which is weak for my subs.. But if I wire them @ 1 ohm, I get 1500wRMS which is overkill for the subs . I know these are still high quality subs, so maybe they'll be okay with an extra 200 watts to each of them. Any advice anyone? Thanks, Joshua Amps - 2x t1500-1bd Subs - 2x hdc315's(copper d2's) Deck - 1940's Amplitude Modulation radio

Guest Posted August 22, 2008 Report Posted August 22, 2008 have the gains down a little when you have them at 1 ohm
Pitbullx Posted August 22, 2008 Report Posted August 22, 2008 That amp does close to 2000w rms....... the gain will have to be damn near at "0" be careful Team Devastation Mixed Martial ArtsMachado Brazilian JiujitsuOnce I lock it on there's no escape I don't train to make you tap, I train to tear your arm, leg, or head off.

S1R-BLUNTZWORTH Posted August 22, 2008 Author Report Posted August 22, 2008 Thanks for the feedback everyone- I know Rockford understates their "power rating" for amps, but I ordered mine through Ebay for $265 and it doesn't come with a birthsheet...so maybe it's closer to the rated 1500w instead of a couple of the luckier 1800+watt birthsheets i've seen for the t1500-1bd's (lucky bastards!) . but either way, IMO $265 seems like a -steal- for this amp You don't really think I should keep the gain set all the way down to "0" should I ? Well, then it's a good thing this one dont come with a "bass remote", cause I'd probably blow them on the first day haha! how will I be able to tell if its getting too loud for them? (i know, stupid question) just ordered a 200amp inline circuit breaker too http://cgi.ebay.com/CIRCUIT-BREAKER-200-AM...p3286.m20.l1116 Amps - 2x t1500-1bd Subs - 2x hdc315's(copper d2's) Deck - 1940's Amplitude Modulation radio
S1R-BLUNTZWORTH Posted August 28, 2008 Author Report Posted August 28, 2008 believe it or not, the 8500's seem to love that juicy 1600 watts rms going to them. I'm suprised, thought it would blow the sh** out of them already Amps - 2x t1500-1bd Subs - 2x hdc315's(copper d2's) Deck - 1940's Amplitude Modulation radio
