MTTX 1501D: Not getting the power it i hoped

[psych0ticnemes1 5,000+ posts]

rca from hu to back of line driver, rca from line driver to amp. positive and negative to line driver-done. easy hook up. ill take the infinity for it

what size wire can i use for the line driver? does it need like a "turn on lead" or no

it takes same size wire as your hu, and a remote turn on wire like an amp,its about the same size as a pack of smokes, jus tuck it into your dash.

can i hook it up back by my amps? that way i don't have to worry about running more wires?

Just a heads up, on almost all the MTX amps I've had, and the few I installed, the dont start putting out power until the gain is about 90% up. I cant tell you why, but I;ve read its pretty normal with the 1501d. Others may chime in that have the same amp. BTW: I';ve always used a DMM to set the gains.

iirc i talked to scottie who originally owned and modded one of mine that he had in one of his crazy setups (later i had them rebuilt to normal). anyways he said that with only 1v of preamp, you only need the gain half way to get full power.....now granted this was on a bit ore stable electrical. i had a decent electrical and with a 4v preouts i still needed it close to 2/3 the way up....

definitly upgrade the power wire (i noticed improvment when i did to mine), and slap on a 100amp fuse......MTX say thos things will do 150amps full tilt. i did 140.1dB off a xxx15 with a single 1501d, 4awg wire and 2 red tops, i know you can get morepower out of that amp.....something isnt making since, keep workin on it

as far as clipping it, these amp have a compression circuit which is turned on or off by taking a paperclip (or something of that sorts) and pokin into that little hole on the side of the amp (forgot which side)... with it clicked in its ON, clicked out its OFF.....with this on you will never clip, the amp will internally do what it needs to do to keep you from clipping //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif take that dmm and get that gain up, keep the bass EQ (bass boost ont he amp) down, and try turning ur bass preout up on the HU

this amp has much potential, just needs things set right for it to perform, but it will //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

update: put a dmm on it... apparently i didn't have my gain high enough... i set it as if i were getting 1200rms because my voltage when driving is at 13.5 or so normally, so 48.9 on the dmm... It is tough to tell how far i have turned the gain, so it may only be at half but i'm not used to cranking it, that's all. Kicker amps are very sensitive compared to these. I used a 0db test tone so i won't clip and turned my sub-out from +6 to +4 after setting my gain too. It wangs now //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif Thanks guys...

good to hear man, when used right they'll pound. loved it on my xxx15. the 2 1501d's on the 4hp kicked ***, my first 2.5kW daily setup //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif . Good to see it's got a good home now.

Just a heads up, on almost all the MTX amps I've had, and the few I installed, they dont start putting out power until the gain is about 75% up.

i was gonna say maybe you just have bad imp rise

not sure if you solved your problem but ive also got a 1501d except mine is modded to go down to 1ohm. its currently in 1 ohm and tends to shut off every once in a while. its random when it shuts off.. but i think it has to do with the temperature. will this amp shut off if it reaches a certain temp? cuz on cold days and nights it rarely shuts off. but gimme a heat wave and itll do it more throughout the day. can i put a fan in my trunk to solve this or will a fan not be enough??
