NEED HELP! mtx terminator subs

[skipper89 10+ year member]

I went to my local audio shop today and spoke with the guy, gave him the basic run down of what i was looking for and he sold me 2 mtx terminator 12" subs in enclosed box. the amp that he gave me was an mtx thunder x702. I hooked up the subs and i feel as if the subs are very underpowered(they dont hit very hard).

these are the specs for the amp. http://cgi.ebay.com/MTX-X-Thunder-702X-Amplifier-2-channel_W0QQitemZ250300151342QQcmdZViewItem?hash=item250300151342&_trkparms=72%3A1205%7C39%3A1%7C66%3A2%7C65%3A12%7C240%3A1318&_trksid=p3286.c0.m14

these are the specs for the subs

Power Handling : 200 Watts RMS / 600 Watts MAX Power (Per Subwoofer)

Power Handling : 400 Watts RMS / 1200 Watts MAX Power (Combined)

Dimensions : 14"(H) x 29-1/2"(W) x 13-1/2"(BD) x 11"(TD)

Approximate Weight : 66.4 LBS

so this amp

with which subs? are they 4 ohms or 8? i'm thinkin 8 and he's wanting you to bridge the amp and wire the sub in parallel giving the amp a 4 ohm load.

 

[skipper89 10+ year member]

yes, thats the amp. the back of the sub says 4 ohms by the speaker connection so im pretty sure 4 ohms.

sell every thing start over trust me

 

[Horsemanwill 10+ year member]

ya so it's a "prefab" mtx box and each sub is 8 ohms so bridge the amp and if to you that's not loud enough then you're gonna have to spend more money then you did the first time.

 

[skipper89 10+ year member]

are you sure that i can bridge the subs with that amp?

 

[DBBOOM 10+ year member]

Who did the install, what type of car and how is the box(i.e how big and placement in the car)?

 

[Horsemanwill 10+ year member]

if the shop gave you the box with the subs in it and on the "terminal" you said it says 4 ohms and there is only one terminal then yes

pics of the box with subs will help

The subs are single 4's.

 

[Horsemanwill 10+ year member]

if the subs are 4 ohms each then no do NOT BRIDGE the amp to it as it can't handle a 2 ohm load.. if the subs are only 4 ohms each i'd suggest getting a bigger amp.

 

[skipper89 10+ year member]

no there are 2 terminals. so bigger amp i suppose or would you suggest just buying a whole new setup?

 

[Horsemanwill 10+ year member]

depends on what kind of sound your looking for if your looking for all out loud bass and makin the neighbors complain yes

 

[skipper89 10+ year member]

im not looking for insane glass shattering bass, but im looking for a nice deep bass that will sound good with my music for a decent price. the reviews that i am reading for the subs are pretty good and people seem to be happy with this set up. could it be possible that i hooked up the subs wrong? i connected the + and - from 1 channel to the positive and negative for one sub, and the same for channel 2. the subwoofers are single 4 ohm voice coil.

 

[Horsemanwill 10+ year member]

you seemed to have them connected right are you sure you don't have one of the wires switched on accident? just to make sure switch the wires on one side amp put the neg from sub on the pos for amp and so on but just on one sub. leave the other the way it is.

you have a 70 x 2 amp pushin subwoofers LOL!!!

Get an amp that does 600-1k at 2 ohms and sell that amp as fast as possible or take it back, its worthless for subwoofer use- look at the classifieeds here for deals.
