I have a Cadence ZRS-C65 with two SA-10 D2s. When setting the gain, do I go by the impedance the subs are wired to (2ohm), or what they actually measure at when I test the wires with a DMM (2.7ohm)? Also, when voltage drops does the power drop, or does the amp draw more to keep power where it should be? My electrical isnt up to par at the moment (all stock), so I sit 13.8v idle, and drop to high 12s when the amp reads ~30v. So if thats 450w at 2ohm, which would be 32amps if it stayed at 13.8v. Since it doesnt, and drops to about 12.8v, does that mean it draws 35amps instead to make the 450w, or does it continue to draw 32amps and only put out 410w? And when figuring effi…

Hey all I need to re wire my car and move my batts back and get them off my back seat so I can compete.So i was wondering instead of having to take all my wire that I ran out,Could I just use a distribution block as a means of extending my wire?Here is a pic of what I have currently and what Im talking about doing. Sorry for crappy drawings lol.So if you understand what im talking about doing, will it work ?Thanks

the kicker zx1000.1 has a 0-18db variable bass boost at 40hz.. my question is if i want to run my IDQ15s ported and tuned to 28-30hz would the bass boost hurt the sound of the subs?

I have an Alpine CDA-9886. The way have mine set is I have the sub out on 15 and the gain on my amp set at a moderate level. I notice a when play it at 20 it'll be hitting good, but when I turn it up past 20, that bass stays at the same level and doesn't get louder. My friend said it's my deck and he has had simular problems with Alpine's and has me interested in a nice Pioneer deck if my deck is the problem. I'd like a 2nd opinion from you guys.

Okay so I'm trying to get a estimate of how much wattage I can safely put out without harming my amp's by the voltage dropping. I have a relatively small car, it has a 70 amp alt and I'm not sure about the battery. I was originally going to just run 1000watts on stock electrical but I figured if I upgrade my electrical I can go a little bit bigger. Now lets say I do the big 3 on my little car and I add a deep cycle battery in the back for the amp, how many more watts would I be able to run? And one more thing when you have a voltmeter what is the danger zone in volts? I think it was 11?

I'm running a sundown sae1200v1 at 2ohms running voltage is 14.6 it dips down to 13.7-13.4... I'm running 1/0ga about 5 foot run its cca though all I had for ground was a chunk of 2ga it's about a foot long ran to the frame ... also got a 1/0 ga battery ground to the frame even went to a relay harness for the headlights

Ok guys, I'm from the UK, but i'm over with you in the states for the next 8 months or so. Staying out in Melbourne, Florida. I'm after either a decent 3000W rms @1 ohm class a/b amp Or a class D, or pair of class D's with good dampening factors, with about 3kw @1 ohm ultimatly. I have back at home an AA Mayhem 15", which i powered with a Powerbass xa3000D. Which i liked, but i want something to control the woofer better. I've heard US amps merlins and i liked the sound of them . They were running @ 2 ohm though, but i could run one per coil. As i'm not used to prices on things out here, roughly how much money are we talking for a pair of merlins mono's, totalling ~3k? O…

I have a pretty basic question. I am looking to upgrade the amps I have to Sundown amps. I need to know if the current wiring will be enough and if not what I need to upgrade. I am having a authorized dealer install these so I just need to know what I need to tell them. I have the following gear: Car: 2001 Jetta GL 2.0liter 4 cylinder Headunit: Kenwood KDC-MP438U (3 sets pre-outs) Fronts: Polk Audio db6501 component speaker (max of 125 watts continuous), door mounted Rear: Polk Audio db6501 component speaker (max of 125 watts continuous), door mounted Sub: 10" Treo TE dual 4 ohm sub (500 watt max), mounted in a Ported ProBox Wiring: 4 gauge Memphis 2 amp wiring kit I a…

i was just wondering how much the EXILE XI1500.1 cost?

Whats this CD player compaired to a dual or Jenson flip up? Is this CD player good enough to some mids and highs? Lemme get some feedback..

Promised pics of my D7's when I got them. These are quick shots. I will get some better ones once I get some more time. These are the finest amps I have ever seen or touched in my life. They put the Zap's to shame really bad. Each one weigh roughly 20 lbs. and the build quality along with the crossover's and list of features and options are unmatched by any amp. I have not heard them yet but I can be pretty sure with the statement that these amps will go toe to toe with anything. DAMN! they look good. I am so happy I chose these over the Zapco's.

Just wondered if anyone has used one before on an AGM type batt ? (regular or Jr version)

Alright, I just put a new Fi Btl 18 in my 97 dodge ram 2500. It is diesel and has a h/o alternator and duel batteries. I was using a power acustik OVN1 5500D amp. It is connected to a battery with zero gauge wire for both the positive and ground. The gain was only turned up about half way with the BTL running at 1 Ohm. I did not listen to it all that loud, however one day the bass cut out and then the amp started to smoke. I immediately shut off the radio and felt the amp. It was cool to the touch. The amp was only in for a week and had only been used maybe three times.... When I got home I turned the radio back on and the LED indicator came on but no power is coming out …

One of these will be my next amp. The T1500 may or may not be the CP version. I will decide that if I decide to go with the RF amp. Will be powering two DC lvl3 15's.

Do you like the new 45 degree angled connectors or the straight out connectors?

hey guys, its been a while since i last was on here. Broke down and decided to get 4 skar vvx10's for my truck. Its a 2001 ford f250. The woofers are d4's so ive been trying to figure out which was the bes route to go with amps. I wont lie, I picked up a Soundstream rub1.1600d initally and was going two run two of them (2 woofers per 1600). Electrcial wont be an issue as i already have a 270 amp alt and an xs power 3000 secondary battery. Deka batt in the front. I'm just stretched on amp choice. I've looked at everythng and just cant decide. I trust the soundstream, but if there is better out there, i wanna try them. any suggestions? if i could keep it under $800 id be st…

when i have the motor running, & i turn off the system the Planet Audio TT850d makes a pop through the subs !!! ??? i sent it in to get it fixxed and they said they swapped out the board and sent it back so i hook it up and it lasted for about 1 day befor it started the POP thing agine.... so iv tried different amps and NONE of them POP when i turn off the system i.e. ( PPi / JL Audio / Mtx / Hifonics ) !!! any one have a clue as to why the PA Amp pops @ shut down ??? iv tried different ground locations, re-ran the remote w/ new wire, re-grounded the Kenwood & Kove, cant seem to get the amp to quit making a pop when i turn it off.... oh ya it does NOT pop if th…

Ive got a class D Mono amp that keeps shutting off while playing music. before It used to do it if there was a weak signal but now its starting to do it no matter what. I have to turn off the HU then turn it back on to get the amp working again. In the last vehicle it was in the remote wire was connected to a fuse under the dash and the wire's insulation rubbed off somewhere. the wire touched metal on the vehicle and burned out the wire. for a while the amp wouldnt even play any music but then started workign again. btw, that happened almost exactly a year ago... had the amp for 1 1/2 years & i bass it everyday

Ok, I have decided the XXX, huge amp, heavy optima yellow top 31 series, and massive box is too much for what I need it for. I am selling everything except the Rainbows and my HU to Jamie's cousin. Here is what the next system will be: 2 RL-i 8's sealed in a movable box Rainbows on a 150x2 amp (that seems to be the most power they can take) A matching amp for the rl-i's (around 700 watts) Audiocontrol EQT's and 4XS I would also like to be able to stay in the running for USACi 0-600 sq class. I can get the JBL's for about 550-600 if my eBay powerseller pricematch goes through on SD. I can get the Kickers for around 750-800 I think. I already have a PA VX3002, and anoth…

I'm looking for a good 600 - 700 watt amp. Any recommendations? It'll be to power a pair of Audiopulse Epic 12s. Impediance doesn't matter. Just needs to be able to power a pair of Epic 12s. As for budget, I could spend up to 400.

which do you prefer and why? Myself enjoy a good powerful 2 channel instead of a 4 channel.

I'm curious as to what difference I should except to see switching amps. Currently I have some shitty old soundstream amp, MAYBE giving my SSD 18" 300w. I'm not even sure on that. I'm going to be switching it out for a SAE-1000d. What kind of output difference should I be expecting ? I'm sure overall sound quality will be better, as my current amp is garbage.... But will there be more SPL ? That's what I'm curious about.

i just got word that i might be able to get one of the new jbl amps (bpx1100.1 or bpx2200.1) for cheap.....like manufacturer cost cheap....worth thinking about, i've heard very little about these amps, and if i do decide to go this route it will be replacing my hifonics 1500 to power a xxx15 :boxin:

See the smoked plexi in the middle? What does everyone think? Leave it? Replace it with a clear red? Replace it with clear and have JBL and Crown etched on either side and backlit red?

A few days back I got in my car to head to a friends house. Started the car and as my head unit turned on I heard a sort of pop/thud noise coming from my trunk. It wasn't too loud, but I then noticed my sub wasn't playing. Looked back there and the amp wasn't on. It had worked fine the day before. I checked fuses, grounds, and the remote wire to make sure it was fine. Amp still wouldn't turn on. I opened up the amp and I didn't see any burn marks or any apparent damage, but I took some photos to see if any of you guys happened to know anything... There is one 30A fuse, and the rest are 40A; hoping that had nothing to do with the amp not turning on, its been that wa…
