How can i connect 2 12''s pioneer premier too an jl audio amp n make the bass loud???

Hello m1k377060,

Having your subs in well-designed and constructed enclosures will make as much or more difference in their output than how you connect them to an amp.

The TS-SW1241D's are single voice coil 4 ohm shallow subwoofers that are rated for 350 watts RMS. For maximum loudness, your JL amp needs to be 2 ohm stable and capable of delivering 700 watts RMS into that impedance. Wire the subs in parallel for a 2 ohm load and maximum power from the amp.

Hope this helps.

Hi i have two 10'' jenson xs sub and they are about 6 years old and i was wondering wut amp size i should buy to run them.

I believe these are 4ohms, if so buy a 2ohm stable monoblock amp, that puts out 250-300 watts RMS, and connect your subs to it in parallel, don't pay attention to peak watts, look at RMS watts, or continuous watts. If they're 2 ohms, buy a 2 ohm stable 2 channel amp that puts out 125-150 watts RMS per channel, and 250-300 watts total or bridged RMS output. And connect them normally, on sub per channel... hope this helps, as far as brand recommendations, MTX, pioneer, Alpine, Kenwood... Good luck

I have one mtx t4510-04..what amp do you

Hello jandytaala,

The recommended power range for you T4510-04 is 112.5 to 225 watts RMS. So you need a monoblock amp within that range. You could go up to about 300 watts RMS, but watch the gain and don't try to get too much from a single 10" sub.

The Orion Cobalt shown here would be a good match and is only $139.99. For another $60, the Alpine MRP-M500 will output 300 watts into 4 ohms.

Hope this helps.

Is amp big enough for speakers


To run 2 subs, the amp would be a little small. The subs will run OK, they just won't be very loud.

It's usually better to compare and match up the RMS power rather than the peak power. The Sony XS-L10P5B sub has a peak power handling figure of 1200 watts, but the RMS is 300 watts. The Sony XM-ZZR3301 monoblock amp puts out 1100 watts peak, but only 330 watts RMS. They would work great together, 1 sub, 1 amp. But if you add another sub, each one would only be getting about 165 watts. They'd work OK, just not as loud as they could be.

Hope this helps!

Need proper wiring details.

This is a dual 4 ohm sub. By wiring the terminals in series (one set of + to - from one side to the other) you will have an 8 ohm sub (most folks probably don't want this). By wiring in parallel (+ to + and - to - and connect the - wire to the - terminal on your amp and the + wire to the + terminal on your amp you'll have a 2 ohm sub.
